Check out what some of our happy patients are saying about us:

Sarah C. from Everett, WA (Source: Yelp)


I have been a patient of this office for nearly a year. I originally heard about the office from an online review who stated that the dentists were the best that they had ever been to. I hadn’t been to the dentist for awhile and decided to give them a try. I needed to get my wisdom teeth taken out. The office staff were very friendly from the time I entered the office. The hygenist who took me back for my appointment put me at ease and was very attentive to my needs. Dr Aylen was very professional but had an amazing bedside manner. She made sure I was not in any pain and made sure to explain all of the procedures to me. The hygenists and dental assistants were amazing at making me feel comfortable and taken care of. Dr Aylen even called me that night at home to be sure I was doing okay and to see if I had any other questions. I have been to this office several times since then for a cleaning and to do some other minor work. For the cleaning and minor work, I saw Dr. Aluas. She was also very easy to talk with and very professional. She was very knowledgeable and made sure that I understood the procedures and the treatment plan. The office is very up to date with digital xrays, cable TV at each patient chair, and special cameras so the dentists can show patients what needs to be done at a close view. The front desk team make sure to work with you regarding your financial situation and your insurance. I would highly recommend this office to anyone needing a dental cleaning, wisdom teeth extraction or any other dental work.

Dr. Aylen and her staff are so compassionate and thoughtful in what they do. They take the time to answer questions and put your mind at ease, which can be so rare in the medical industry. I so appreciate being given different options and being able to talk through them to find what works best for me and my family. We’ve been multiple times during COVID and the dental staff is wearing full PPE, reception staff have masks and there’s lots of sanitizing happening. Thank you so much for your care, Dr. Aylen and staff!

I have anxiety about visiting dentist and doctor offices. Karla Aylen made me feel at ease and took time to explain things and make me feel comfortable. I haven’t visited the dentist as much as i should over the years due to my anxiety but that is lessening as I’ve had nothing but good experiences with Karla Aylen. She was also great about developing a treatment plan for work that needed to be done that I’d be able to handle with my anxiety. I will continue to go back to Karla Aylen and highly recommend her and the staff at the office.

A. W. from Seattle, WA (Source: Yelp)


We have established dental care with several dental offices from coast to coast, and now that we are living in Seattle I have to say, Northgate Smiles is the best for dental treatment, professional care, feeling welcome, benefits explanation, and office environment. Anytime we come in for an appointment we receive premier dental care, they go to great lengths to explain procedures and costs, and ensure you feel comfortable during the entire procedure. The office is classy and is technology-wise superior. I feel fortunate to have Dr. Karla Aylen and the Northgate Smiles Dental Team taking care of our dental needs.

The women at the front desk, Sandra and Meghan made me feel comfortable and set the tone for the rest of my appointment. I hadn’t been to the dentist in quite some time and naturally was anxious. Sandra helped me through the paperwork process which is never fun, and having left some information out, she was kind in helping me correct my mistake. It wasn’t long after that I was called back to begin my cleaning. The man who took my x-rays, Artem, was very kind. I had given him a heads up that I may get a phone call at 1pm for work that I would have to take. He worked efficiently to make sure that we were done with the x-rays before the time of my call, and was understanding when I had to step outside for a few minutes to take the call. I really appreciated this, assuming it was an inconvenience being the last patient on a Friday, no one wants to stay longer than they have to, but he didn’t make me feel like an inconvenience at all. When I returned, Dr. Aylen went over my x-rays and did an exam. She let me know I had several cavities, and some that they had to keep an eye on. No one likes to hear bad news, but Dr. Aylen did it in a way that didn’t make me feel shameful or embarrassed. The office had some technology that was new to me. They were able to pull up on a screen in front of me my x-rays, and even some pictures they had taken of the inside of my mouth. Being able to visualize what she was telling me about my mouth made it easier for me to understand. Once we were done, I got my teeth cleaned by Lea Ann. I couldn’t be happier with the job she did. I walked out feeling like my teeth were in a much better state than when I walked in. She did a thorough job, in a delicate way, instructing me on things/areas I need to work on along the way. I don’t think anyone every looks forward to going to the dentist, but Northgate Smiles has been an overall exceptional experience for myself and my family. I will recommend their services to my friends and family.

Braeden D. from Lynnwood, WA (Source: Yelp)


Northgate Smiles, Dr. Aylen and Staff…wonderful! Very comfortable office, pleasant and friendly- eases the anxiety of going to the dentist. I have 2 crowns that need to be done. I’ve been putting it off for fear of getting major work. Dr Aylen and staff have been great at assuring me its the right decision and needed work. Front office staff has been great in communicating with me the costs and how insurance works with this process. So next step…2 crowns. Couldn’t imagine going anywhere else!

Jenifer M. from Seattle, WA (Source: Yelp)


I have been a patient of Dr. Aylen’s dental practice for more than three years. Her staff is always very warm, welcoming and accommodating. Dr. Aylen and her staff have worked with me for my general dental needs including veneers and also partnered with my orthodontist throughout my adult orthodontia treatment to ensure my teeth remained healthy throughout treatment. I have always been completely satisfied with all of their services and would highly recommend them.

I’ve been going to this office over a decade now. I recently had a filling done on one of my front teeth. I had put if off for over a year being concerned it might not look natural when I smile, but finally gave in and had it done. Dr. Aylen had me in and out in less than 20 minutes and the filling looks flawless, completely matching the other teeth. I asked my wife if she could tell which one and she had no idea. Very pleased with the work. Regular cleanings have always been thorough and well done. Super friendly staff in all facets of the operation. Never had an appointment start late or run late.

Vanessa G. from Bothell, WA (Source: Yelp)


I have an extreme fear of the dentist and had put off my annual appointment for two years. My previous dentist had retired so I had to find a new place to go and had additional anxiety due to change as well. All of my previous anxiety disappeared as soon as I walked into the office. The ladies at the desk were extremely kind. As soon as my dental hygienist came to retrieve me I knew that my visit was going to be pleasant. She was SO amazing and knew exactly what to say to help me feel at ease and calm. She was totally engaged and beyond nice. My time with her was so positive that I have decided to stop taking my kids to their pediatric dentist and start taking them to Northgate Smiles. Dr. Aylen was very professional and warm. Often, I feel intimidated my dentists and doctors but not once did I feel uncomfortable or nervous. Overall, my experience at Northgate Smiles was positive and as enjoyable as going to the dentist could be.

Mohammed Y. from Seattle, WA (Source: Yelp)

Northgate Smiles is an top notch dental office. The dentists at Northgate Smiles are the best in Seattle. I’ve been going here for a little over five years and am very happy. The entire staff is professional, friendly and helpful. I enjoy my teeth cleanings every 6 months, Linda, LeaAnn and Hailey all have done a nice job cleaning my teeth over the years. A few years back Northgate Smiles even took out my wisdom teeth when they started hurting, I was scared but Dr Aluas did an amazing job; I’m so happy and grateful I got them out. If you are looking for a great dentist in the area for a tooth ache or a cleaning, call Dr Aylen and her staff. Thank you Northgate Smiles for giving me a nice smile and keeping my teeth looking good!

Lacey B. from Mountlake Terrace, WA (Source: Yelp)


Northgate Smiles is a great choice if you have anxiety around dentistry. Dr. Aylen and Dr. Aluas are patient, reassuring, and always sensitive to my needs during a procedure. They offer several options for managing anxiety, and they do excellent dental work. I have been coming here for ten years. I had another dentist for a year due to a different insurance plan, and I switched my insurance back so I could come back to Northgate Smiles. Highly recommended!

Jesse C. from Seattle, WA (Source: Yelp)


There are a couple of complaints about pricing on here that I want to address. Dental work pricing here is competitive with others in the area, and I cannot stress how impressed I have been with Dr. Aylen’s work. From an emergency wisdom tooth removal to simple fillings, she has been great! The staff is always friendly, knowledgeable and welcoming. The entire process goes at your pace, showing you which teeth are most important to get done, while focusing on utilizing your insurance most efficiently as well. You have total control over which procedures you’d like to be done first. I avoided going to the dentist for a long time, but I love going now!

Caroline T. from Kenmore, WA (Source: Yelp)


From the moment I walked into Dr. Aylen’s beautiful and exceptionally spotless office I was impressed. My Children played with the toys in the toy box while I enjoyed a lovely cup of coffee. The front desk staff were so polite and accommodating. I was called back on time. As for the dental care, it was the most professional I have ever experienced. Dr Aylens’ office is up to date with all the latest technology. The work I had was quite involved and completely painless. Dr. Aylen explained everything to me in terms that I could understand. The staff really made me feel at ease as I don’t like going to the dentist. However I will be happy to return to this office anytime and I will definitely recommend Dr. Aylen to all my friends. Thank you Northgate Smiles for a wonderful experience.

I moved up here less than a year ago and chose Northgate Smiles as my new dentist and couldnt be more satisfied! The staff and are not only friendly and helpful but are highly knowledgeable. I wouldn’t want to go anywhere else after experiencing the excellent service at Northgate Smiles, you won’t be disappointed!

Li Anne T. from Seattle, WA (Source: Yelp)


A B. Seattle, WADr Aylen gave a superb effort in my 1st visit with her . With x-rays and digital images, she gave me my best ever comprehensive exam I believe I have ever had. I wish I found her years ago! She took time and was very thorough to explain all the work I needed (4 crowns and 4 fillings) and answered my questions with concern and sensitivity. She and her staff were very pleasant and friendly and made me feel like I had been a patient there all my life. I committed to her treatment plan with ease believing that I am in capable hands with her and her associates there at NorthGate Smiles. I have little anxiety sitting in her chair knowing I am in such good hands. As well, Dr Aluas and D.H. Leah was super too. Both were very personal, attentive to my needs, pleasant to talk with and handled their tasks with efficiency and obvious experience and knowledge. I feel I am in very good hands at NorthGate Smiles and it good to find a dentist office I firmly believe I will have on my health-care team for a long, long time!

Northgate Smiles has been my dental destination for 40+ years and several ownership changes. The dentists, assistants, and office staff have always been friendly and competent and though I could walk to hundreds of dentists from my downtown Seattle residence, I’ve never considered leaving Northgate Smiles, an office Dr. Karla Aylen continues to make as professional and enjoyable as any trip to the dentist could be.

Ron Reed (Source: Google)


Dr. Aylen and her Northgate Smiles team make me feel welcome and comfortable in their care. Lea Ann is my favorite Hygienist and always performs a thorough cleaning with just the right balance of technical skill, professional critique, and personal encouragement. She identified some trouble areas on my first visit with her and was very diligent to ensure a good quality cleaning of those areas, and the rest of the mouth. She then provided home care guidance to help me maintain my clean, healthy teeth and gums. I followed “most” of her guidance including the use of a Sonicare electric toothbrush and my teeth feel cleaner longer and my subsequent visits are more of a check up than a challenging clean up. If you read this far it should not be a surprise that I highly recommend Lea Ann and the Northgate Smiles team!

Ryan B. from Bothell, WA (Source: Yelp)


If you are looking for a great dentist, Dr. Karla Aylen is one of the best. I consider myself a “tough guy” but am timid when it comes to dentistry. Karla was extremely gentle, walked through every step, and has changed my opinion and nervousness associated. I also experienced a very minor dental emergency and Karla met me within an hour at her clinic on a Sunday (they are usually closed). An added bonus is that she is very nice and a charm to be around.

Erin S. from Seattle, WA (Source: Yelp)


I can’t say enough good things about Dr. Aylen and her staff. Dr. Aylen is friendly, kind and gentle. She really cares about her patients, explaining everything in detail, and even calling to check on you after a major procedure. She is also great at anesthetic injections! The worst part of the dentist for me has always been the novocain injections. Ouch! Dr. Aylen is gentle and fast, minimizing the normal discomfort of these injections. Tammy, the hygienist, is friendly and funny. She tells great stories that make my cleaning appointments fly by. Dr. Aylen’s office staff is genuinely friendly and helpful. They always greet me by name when I walk in the door. I would recommend Dr. Aylen to anyone looking for a kind and competent dentist!

Mary L. Bergeron (Source: Facebook)


I have been a patient their since 2010 and couldn’t be happier. I have referred 3 of my friends to them too and from what I hear are just as happy with this office as I am. I am very thankful for the happy reviews I read online before choosing to go here 4 long years ago. I wanted to pass on the happiness out to others who are looking for a wonderful dentist. I recommend northgate smiles to anyone and everyone. My very 1st filling I had done with them, Dr Karla Aylen called me herself the following day to make sure I was feeling as good as I possibly could. I was 100% confident at that point, I had made the right choice for all my dental work in the future. I am very thankful to have a trustworthy, great dentist.

I am so glad I found this dental clinic while doing research online. Everyone at this clinic is very professional and so nice. I appreciate that billing questions or issues can be promptly taken care of on the spot. Actually, I have never gone to an office that managed billing as efficiently as they do. Northgate Smiles takes customer service serious and everyone I have been dealing with at this office is patient focused and ensures you are comfortable and well taken care of. My husband is also going to this clinic and we both could not be happier with our dentist and dental hygienist. I highly recommend this dental clinic.

Let’s face it. No one enjoys having to go to the dentist. But everyone who works at Northgate Smiles seems to understand this. The reception staff, hygienists and doctors are all a delight to deal with. They try to make what can sometimes be a traumatic necessity into an, if not pleasant experience, at least one that makes you feel like you’ve been in the best care possible.

Liba Z. from Seattle, WA (Source: Yelp)


About a year ago I had to change my dentist because I got new dental insurance. Fortunately two of my friends recommended me Dr. Aylen at Northgate Smile. I made an appointment and was very happy I did so. Dr. Aylen and her staff are very experienced and skilled professionals and I always feel welcomed there. My teeth are in bad shape (overbite, cross bite, receding gums, deep pockets, gingivitis, damaged enamel, prone to cavities, tons of filings) and need a lot of attention. Dr. Aylen and her dental hygienists managed to keep everything under control and I haven’t had any new cavity since. All procedures were done with great care and almost no pain and I never have had any problems or needed any additional repairs afterwards. I also appreciate follow up calls after treatment and appointments reminders. I will continue to see Dr. Aylen and I am planning to start Invisalign treatment with her shortly. I recommended Dr. Aylen to my husband (he needed cleaning) and he was very happy with the services as well.

Serena M. from Seattle, WA (Source: Yelp)


Sea foam green carpets, blue and beige suede chairs. Soothing lighting and soft tones. I did not realize going to the dentist could feel as though I just arrived at a spa for the day. I had the most wonderful experience at this particular dentist office. Being a new patient, I had no idea what to expect. From the time I entered the office, I was greeted with a warm welcome by name. You are offered bottles of water, tea, and coffee. The reception staff is prompt and quite kind as well as the hygienist. Conversation flowed in between my cleaning and x-rays. I am surprised to say I actually had fun at the dentist office. I look forward to returning for any necessary work. Dr. Aylen was amazing and well worth the visit.

Nate M. from Seattle, WA (Source: Yelp)


Simply the best dentist I have ever worked with. Dr. Aylen and her front office staff is absolutely delightful to chat with, my questions are always answered and I ALWAYS feel as though they have my best interests in mind. I’ve been a patient for well over 4 years and can’t imagine ever being seen by anyone else. I’ve been seen for routine cleanings and X-Rays as well as minor procedures, Invisalign, and teeth whitening. I love them so much that I’ve referred roughly 8 of my co-workers and friends who all agree that Dr. Aylen and her team of dental professionals are amazing! **I was surprised to read some of the reviews left by others who we’re not RAVING about how great a place Northgate Smiles is and how amazing the entire staff is there. I would highly recommend to all!

S. J. from Seattle, WA (Source: Yelp)


I have been seeing Dr. Aylen at Northgate Smiles for a couple of years now, and I couldn’t be more pleased! Previous dental offices have told me my teeth are cracked from grinding and that I should consider getting veneers. At Northgate Smiles they let me know my teeth are just fine, although a little worn down from grinding, so I should consider a mouth guard – quite different from the price of veneers! When I first went to see Dr. Aylen, I needed an implant (crown), and it turned out my post is not a standard one, so needed a particular setting. She notified the lab making the implant about the non-standard post and arranged someone from the lab to come up during my exam to take a look. After my appointment I went down stairs to get the final details worked out. It made everything so easy for me. And finally, my dental hygienist Cindy is fantastic! She’s very easy to talk to and makes my cleaning seem to last no time at all, and my teeth feel great when she’s done. I highly recommend Northgate Smiles!

I’ve been going to them for years and drive over a half hour just for the friendly service of Dr. Aylen and her team. I especially love the cheerful attitudes of Sandra and the other ladies at the front desk who always put me at ease before getting my teeth worked on. If you live near Northgate, I would highly recommend checking them out for your next dental appointment.

Justin Wade (Source: Google)


Let’s start by saying…I HATE dentists. I looked around and came across this shop. Tracy the front desk lady got me in the next day after I described to her my symptoms (I am glad I listened to her). Monique was my Dental Assistant and she worked really hard to comfort me. Her and I had a great chat until Dr. Aylen showed up. She was very personable, took her time with me, and gave me all my options in detail. I have few things that need to be taken care of. Knowing this is a one stop shop, makes me happy.

M. G. from Kenmore, WA (Source: Yelp)


I am a fan! I love going to the dentist now! Dr. Karla Aylen and her staff are truly attentive, kind and friendly. I like the professional yet warm attention I recieve from the minute I cross the threshold. My treatment plan is clear to me and I am happy to recieve helpful information, in a positive manner. It feels like we are working together to really make my smile the best it can be. My husband and son also go to Northgate Smiles and it is equally good for them, they leave happy and cared for. My son is 6 and it has been a great experience for him because of the friendly treatment and Dr. Aylen’s humor and patience. Never had any problem with billing or insurance, smooth operation all around. I recommend.

Cale W. from Seattle, WA (Source: Yelp)


My wife and I have been going here for a few years now and it is the best practice we have ever been to. Dr. Aylen and Dr. Aluas have both worked on my teeth and I would recommend them both. I have had my biannual cleanings, wisdom teeth removed, a crown and a couple fillings done here and the Dr.’s and their staff were great through each procedure. After my wisdom teeth were removed I had dry sockets that started late on a friday night which were very painful. I called the office that night and Dr. Aylen came in early Saturday morning on her day off to give me the medication/ dressing necessary. There was no extra charge for this service and Dr. Aylen was very kind and helpful.

Ghia C. from Seattle, WA (Source: Yelp)


First of all it was tough for me to transfer care since i really liked my previous dentist but had to find a new one that is closer to my house.When my dental insurance emailed me the lists of all dentists around my area i had to google each one of the them and dr Aylen had the best review online. And those reviews weren’t wrong everybody in this clinic are so nice and very friendly. Dr Aylen is very thorough and very caring. She even called me the day after my procedure checking how i’m doing.

Leanne Rutland (Source: Facebook)


I am so happy to have found Northgate Smiles! The staff is sooo friendly and respectful! I have been able to easily schedule appointments that fit with my busy schedule. The office is modern and very clean. I love the amount of technology they use! I have been able to ask numerous questions with out feeling embarrassed, rushed, or canyoning. The staff makes you feel like you are their number one priority! I would recommend this facility to ANYONE!

I had such a wonderful first time experience with everyone I encountered at Northgate Smiles that I’m looking forward to returning to have dental work done (that is not so pleasant) only because I know I will be in good hands and treated kindly. I laughed my way through the uncomfortable workup x-rays with a technician who made me feel so at ease and comfortable despite all of the hardware and contraptions she had to put into my mouth. That was no easy task! I then felt so at ease and relaxed with having my teeth cleaned that it seemed to be over before it even started. I was not in pain nor did I worry about what was to come next. Everything going on in my mouth was explained to me very well by everyone. What a relief that was and then some. Dr. Aylen was truly a gem when she came into the room. A warm and comforting smile when we met and genuine kindness and concern for what I had going on in my mouth. We don’t always like what we hear when we go to the dentist, but in this case I felt so educated and understanding of what was happening that I felt at ease leaving there. I could not have asked for better dental care providers in all of the staff at Northgate Smiles. Thank you to Dr. Aylen and all of her staff; I’m truly grateful!.

A. B. from Seattle, WA (Source: Yelp)


I had to go to an emergency dental clinic over the weekend, the work they said I needed done was quite extensive so I called Northgate Smiles with the quotes. They got me in right away to get my abscess taken care of and gave me the root canal I needed. I had a very visible cavity but they decided to just focus on the cavity, however, 10 days later my cavity started to hurt so they squeezed me in and did a filling. The staff and dentists here have been so great, I appreciate that I don’t feel judged here. I tend to have a great deal of anxiety about going to the dentist because of the shame I feel for the condition my teeth are in.
