I am so happy to finally found a family dental clinic here in Vegas. We moved here a year ago and I’m glad I found the best dentists for my family especially my daughter. The clinic is very clean, the atmosphere is comfy, and the staff are friendly. They did a detailed check up using their modern equipments which is awesome! My hygienist, Maggie is so gentle with my teeth! I like it! Dr. RJ is very informative and very thorough in his examinations. He really takes time to check with his patients. Dr. Audrey is the best for kids!

I was on the hunt for a new dentist having just moved to Las Vegas. I’m so glad I came across Desert Inn Smiles. Even on the phone, Araceli was very warm and accommodating and responded to all my questions with so much patience. She’s even nicer in person. Roxanne also made me feel at ease before Doc RJ came in to see me. I felt I was in very good hands from the very beginning. I’ve already set up my next appointment!

Evan M. from Las Vegas, NV (Source: Yelp)


Came in for a filling of a chipped tooth. The staff was very friendly. The dentist was friendly as well. A+ dentist and A+ service. I had ZERO pain during the filling. Usually, with other dentists, i feel a little bit of pain but with this dentist, I felt ZERO pain. The place is super clean as well. Highly recommended!!! Three exclamation points because, well, they’re awesome. 🙂 Thank you!

Alma R. from Las Vegas, NV (Source: Yelp)


Dr.RJ saved my smile! I came here with a recommendation from my daughter about how clean and amazing the the office and staff are and let me tell you I was not disappointed! I got my cleaning and the doctor made me feel comfortable and he explained to me my choices with bridges, crowns, and implants. And we decided on implant and let me tell you he must have the softest hands ever because I have yet to feel any discomfort or pain from the process. So happy he accepts most insurances and will always be happy to go back.

Hermón B. from Whitney Ranch, Henderson, NV (Source: Yelp)


I had a great experience at this office. The office is clean and staff is very friendly. But most importantly nobody tried to pressure me to do any service I didn’t want. I went for a missing filling and told them that’s all I’m looking to fix today, and no one came with a list of services I need. They just told me to come back for a full exam when I’m ready. Dr Rj is very informative and easy to talk to, and I’m so happy I finally found a dentist I look forward going to. I will definitely be bringing the rest of my family to this office

Jay B. from Las Vegas, NV (Source: Yelp)


Worried about your teeth? Desert Inn Smiles will put your mind at ease! After changing jobs I had no insurance so I put off going to the dentist for a long time. Since I’m getting married soon, I didn’t want my grill to be all busted on my wedding day. After shopping around, along with a few recommendations from friends and family, I decided to pay Dr. RJ a visit. Cleanest office I’ve been to ever! I really like the decor and color scheme. The attention to detail is amazing, down to the black gloves and masks which I think are pretty cool. They even have TVs in the exam rooms! I was able to watch some of Avengers: Infinity War while I was getting work done. The staff is friendly, welcoming, and very accommodating. I work crazy hours, but they were able to fit me in for a late afternoon appointment. Dr. RJ is very professional. He put my dental anxiety at ease and even turned the appointment into an educational experience! They also have very fair cash pay rates. In case you’re between insurance coverage like me. Thanks for everything! I will definitely come back again.

I was petrified to go to the dentist, however I was in pain. I had called several dentists offices here in Las Vegas and no one could see me right away. I had broken my tooth. Suprisingly I stumbled upon the number for Desert Inn smiles on Google. Understanding my urgent need, they were kind enough to fit me into the schedule. I am so grateful that I reached out to this office. Dr. RJ along with his entire staff are amazing!! They began nurturing my fear of the dentist from the moment I stepped in the door. I cannot say enough great things about this particular dentist. You will be doing yourself an injustice to go anywhere else for your dental care.

I am so very grateful and thankful for trying Desert Inn Smiles. I had to cut my vacation short because I lost my front tooth and when I called for an appointment they got me in immediately and Dr. RJ gave me a front tooth and did so that I made it to my great granddaughter’s first birthday and I could smile for all the pictures taken. His staff is nice, friendly, so very helpful and made me feel so comfortable . I cannot say enough and highly recommend Desert Inn Smiles!

Robert S. from Las Vegas, NV (Source: Yelp)


If you’re looking for a dentist in Las Vegas, you really need look no further. Dr. RJ and his whole staff are absolutely exceptional. I’ve lived in several cities and had many dentists. And between the excellent technology here, friendly and kind treatment, and the incredibly gifted Dr RJ, I’d choose Desert Inn Smiles hands down. Whether it’s just a cleaning, or crown or implant – The combination of quality work within very reasonable pricing – Check out Desert Inn Smiles.

Verenice P. from Las Vegas, NV (Source: Yelp)


I cant get over how amazing Dr. R.J. is! Currently going thru some dental work but also going out of town. Aside from checking on me days before leaving town, Dr. R.J. in advance asked where will I be heading out to. Why you ask? To call his dentist associates and see who will be free incase I’ll need any help with my current situation! You can tell he loves his job, and he as well as his team are very knowledgeable! I love going to the dentist is a false statement, but I love going to Desert Inn Smile is a true statement!!!

Ronald Almendralo (Source: Google)


The team at Desert Inn Smiles is awesome. They provide awesome customer service. I received text messages for reminders for my appointment. The facility is very clean and organized. I went in for teeth cleaning and greeted as soon as I walked in. Dr. RJ and his staff did a very thorough cleaning. I would recommend this office to anyone looking for a reliable and patient first dental office.

Frank N. from Summerlin, Las Vegas, NV (Source: Yelp)


Excellent every time. Like most people as a child had traumatic experiences with dentists. RJ has been amazing, four crowns and a couple root canals later he still delivers excellent service. Overall experience is quick, friendly and inviting. The lobby is modern yet elegant, tastefully furnished and always clean and tidy. My kids love coming to the dentist now!

Kimberly E. from Monterey Park, CA (Source: Yelp)


First time coming to this office today with my daughter.  Found it here on YELP.  The office is super clean.  Dental Assistant, Rox was sweet and gentle with xrays.  Maggie, the Hygienist was sweet too…she listened to my anxiety about dental treatment and was gentle while cleaning my teeth.  Now, Dr. RJ…he is AWESOME!!  Reviewed my dental history and didn’t  try to make up all different kind of treatment I would need that would cost me thousands of dollars.  I have been looking for a dental office that was honest and would only want to charge me for what I needed.  I expressed my concerns with things I didn’t like about my teeth and what I would like fixed…NO PRESSURE to get it done.  I have lived here in Vegas for two years and had bad experiences with RAMPART DENTAL, ALOHA DENTAL and CANYON POINT DENTAL all of them just giving me a long list of a quote for things I need to have fixed!!  I left each place feeling like they just wanted my money!!  Not here at Desert Inn Smiles…I can’t even begin to say how happy I am to find my permanent dental office.  I totally recommend this office if you are looking for a great team!!

Kristi B. from Centennial, Las Vegas, NV (Source: Yelp)


Hands down, best dentist in town! RJ is friendly, thorough and makes sure you’re comfortable every step of the way. What shocked me the most is how quick he was how quick he was to respond to an inquiry I sent via their website. I was experiencing pain when their office was closed and he called me right after I sent the message to help. He even checked in on me the days leading up to my visit. The rest of the staff is friendly and helpful too! To top it all off, I’ve never had to wait long when I go in for my appointments. I fill out the paperwork and get brought in immediately after. I would recommend Desert Inn Smiles to anyone.

Leilani F. from New Braunfels, TX (Source: Yelp)


Dr. RJ and his staff were wonderful at providing superb patient care. I come from Texas where almost anywhere you go you feel like family and not just a paycheck to most. I visited the dental office today for a cleaning, routine check up and recommendations on how to best care for my teeth. My expectations were exceeded and I was helped with everything I needed. Sonia and the receptionist (whose names escapes me) were so helpful, kind and overall they care about you. I am a life long patient for my duration in Las Vegas.

Frances C. from Las Vegas, NV (Source: Yelp)


Dr. RJ and his team are the best! I have really bad anxiety when it comes to the dentist, so I shared that with him during my first visit. He does everything humanly possible to help put me at ease. During procedures, he stops often to check on me and asks if I need anything. After procedures, he checks on me as well. The front office staff and his assistants are extremely helpful and knowledgeable. You’ll always receive a warm welcome, and you’ll always get all of your questions answered in a timely manner.Dr. RJ and his team are the best!

I have nothing but good reports about Desert Inn Smiles! Dr. RJ was very thorough and informative on what was going on in my x rays and explained possible situations that may or may not happen in the future. I have never had a dentist explain the current situation, what looks good, and what to keep an eye on. My visit was a pleasant experience and his staff was very welcoming and friendly. Made an appointment for my husband before I left for his cleaning. We will definitely be coming back. If you want the ease and comfort of knowing you made the right choice for your dental hygiene Desert Inn Smiles is the way to go. Thank you!

Maria A. from Las Vegas, NV (Source: Yelp)


This is my second time coming to this office, I live in Henderson and I dont mind the drive. I appreciate the front desk (cant remember the young lady’s name) she was very helpful since the minute I called on the phone. Dr. R.J is an excellent Dr he explains everything step by step, he answers all your questions. Since the minute he sat next to me he made me feel comfortable and not scared at all. I walk out of there understanding what needs to be done and why. If you are looking for a dentist I definitely recommend Dr R.J.

I love going to the dentist, said by no one! I love going to Desert Inn Smiles, that’s a fact! Dr.R.J. is the best! You can tell he loves his job! I’ve been getting work done for about 3 years there now and I still applaud his customer service. After procedures he will reach out and ask how recovery is going and follow up from time to time, or as simple as when I was laughing while watching Deon Cole (in their rooms which are hooked up to Netflix and always clean) and next visit he says Deon Cole was on the radio and remembered I was watching it. That attention to detail and clients is unbelievable and so appreciated! I recommend you, family, friends, neighbors, associates, coworkers, everyone go to Desert Inn Smiles!

Very good customer service at Desert Inn Smiles Dental Clinic.Dr RJ Guideng is my Dentist of choice.He is excellent and compassionate.He treats you like a member of his family.I highly recommend him to my friends and family.They strictly adhere to the CDC guidelines for COVID. The office is clean.The equipment ,specially the Xrays and Ct Scan are hi tech. Dr.RJ explains his plans of treatment depending on the result of the panoramic xrays and Ct scan.Dr RJ makes you feel comfortable while drilling your teeth by constantly explaining what he is doing and asking if you are ok. Dee his assistant is very nice and compassionate too. I am highly satisfied w the care I am getting from Desert Inn Smiles. Special acknowledgement to Araceli their Office Manager,she has an excellent customer service.

Imelda P. from Las Vegas, NV (Source: Yelp)


I had the greatest experience ever in this office . I never had a painful tooth until recently so Dr Rj was highly recommended . It was good that I got a same day appointment . The office is so clean and looks elegant . There was a warm reception by staff and their assistant looks knowledgeable . Dr Rj is the best . He was able to diagnose right away what is causing the pain and procedure was done to fix it . The procedure went well with no problems . Being in the medical field I would highly recommend Dr Rj to anybody with dental problems without any reservations .

Dr.R.J. is the best! In the middle of getting some work done I had some issues with gum swelling and pain so I was able to go back in before my original follow up which was great since I would be going out of town for Thanksgiving. He asked where I was going and what city I’d be staying at, why you ask??? Because he wanted to reach out to his associates in that area to see who’d be available incase I would need some help!!! Now that’s dedication to your customers! I highly recommend YOU reading this review to go to Desert Inn Smiles and tell your family and friends to go too! All the staff in the office is amazing!!!

I’ve been going to this place for the past 6 – 8 months and it’s honestly the first place in my life that I’ve felt welcomed and they’re often more involved in my teeth than I am at times. Dr. Guideng is extremely helpful and comforting and will pretty much break down the process of any procedure so that you don’t get left in the dark. I’ve been in for cleanings, fillings, and a crown and each time I’ve left genuinely satisfied.

Frederick B. from Las Vegas, NV (Source: Yelp)


Just visited this office for the first time. Dr. RJ was awesome and very thorough with my exam and cleaning. The office was really nice and modern, the color scheme was bright and clean.  I was surprised to find out that even infants needed to see a dentist once their first teeth come in.  We’ll definitely be taking our 11 month old to Dr. Audrey since she specializes in pediatrics. Front office staff and dental assistant were super friendly as well… my family and I will be coming back!

Chris N. from Las Vegas, NV (Source: Yelp)


Moved to Las Vegas from the SF Bay area in 2019 and I’m glad I found Desert Inn Smiles for my dental care. Dr. RJ Guideng is undoubtedly a top notch and excellent doctor. He is professional, friendly, and an expert in his field. Two weeks ago I had two molars and a bridge that was making my life miserable. Because of Covid I was hesitant to have my infected tooth checked. I’m glad I did because Dr RJ Guideng took action immediately. He decided to do my oral surgery right then and there. The procedure was pleasant and comfortable. I highly recommend Desert Inn Smiles to anyone who needs dental care. The staff is friendly and caring. They took care of my insurance and the cost was very reasonable. The dental clinic is immaculately clean and modern. This is the BEST dental clinic in Las Vegas!

Charles B. from Las Vegas, NV (Source: Yelp)


I moved to Las Vegas, to the Lakes at the time, three years ago. I needed a Dentist and RJ was close, so, off I went. In my lifetime, unfortunately, I’ve seen a lot of Dentist. This one, I do not mind at all. No anxiety, because I know it means solutions and answers. They thoroughly diagnose, have some pretty impressive modern equipment from 3D scanning to other Sci Fi fun stuff. I have never had to wait a long time if in pain, or for needed crown(s), etc. And even in the midst of the largest case breakout of Covid in History in Las Vegas when an exposed root started throbbing, they got me in and got it solved. The staff is great, and they worked with me on my insurance for when it hadn’t quite kicked in. Once, a metal bed frame in a garage fell on my face (don’t ask) and RJ saw me immediately, x-rayed my jaw area (thanks again, Marie Curie)  and made sure no teeth were cracked. On a Saturday. For nothing (regular office call). As long as I live in Las Vegas, I have no need for any other Dental Care. And hopefully will only see him every three months (I clean often because of several bridges and crowns).

On a scale of 1 to 10 how scared about I of the dentist? 12!!! I was happy the office was so close but Omg! When you come in it’s like your going to a spa. So inviting. So clean and the ladies were so nice. I felt like I could just rest here. I’m going back tomorrow for a deep cleaning. Maggie the dental hygienist is the best. Super patient with my anxiety of encouraging the whole way.

I was here for a chipped tooth. A+ dentist and A+ service. The staff was very friendly. The dentist was friendly as well and knew what he was doing. ZERO pain. Usually, with other dentists, i feel a little bit of pain but with this dentist, i felt ZERO pain. The place is super clean as well. Highly recommended! Thank you!

I’ve been in Las Vegas for a little bit over a year. Finding a dentist is really hard especially if you do not have anyone to refer you. Desert Inn Smiles is less than five minutes from my home. I chose them for their five star rating with no regrets.The staff Is very professional, extremely friendly and make you feel very comfortable. The dentist R.J. Guideng is very patient, great bedside manner, and explains everything in detail. He totally understood the hot flashes I was having and accommodated me during my dental procedure. If you do not live in the area, I highly recommend making the drive. I will continue my services with Desert Inn Smiles and will now be bringing my family members.

Eugene F. from Northwest Las Vegas, NV (Source: Yelp)


Long story short, I have only had one dentist work on my teeth throughout my life. He decided to finally retire a little while back. Finding another dental office or specifically DENTIST for that matter that you can trust can be hard. Finding Desert Inn Smiles has been a BLESSING! You can tell everyone enjoys working there and everyone always is happy. Dr. Guideng and his staff treated me like family therefore making me feel as comfortable as one can be. I can say I do miss my old dentist, but truly am happy I found this one!

Robilyn Y. from Tacoma, WA (Source: Yelp)


I had my first appt with this facility today, after my husband went there twice. They are very friendly, and accommodating. I believe my hygienist was Maggie, she was super sweet and had very light hands throughout the cleaning. We have had problems with other places , including hygienists who were really rough, so as silly as it sounds that was really nice. The dentist was great, very informative and always willing to explain if something wasn’t understood. The whole facility is very clean and I really felt comfortable throughout the visit. I’m going to recommend him to my adult son to go here as well since I really felt they were a competent and friendly facility. Thank you !

Kimberly N. from Las Vegas, NV (Source: Yelp)


I am not a fan of going to the Dentist at all. I found Desert Inn Smiles while searching online for a dentist near me; what I found was so much more! The atmosphere is welcoming, and spotless. The staff is extremely friendly, both in person and on the phone. I met with Dr. R.J. who spent time reviewing my X-rays, MRI, and 3D X-ray with me, helping me understand treatment needed. At no point did I feel embarrassed or judged for my oral health. Instead, I felt informed, and confident in the treatment plan discussed. That same visit, I was able to undergo a cleaning with Maggie, who is the most gentle Dental Hygienist I have ever been treated by. It was sooooo nice being able to get same day treatment on an initial visit. Normally the day after a cleaning my mouth is sore, but not with Maggie. I woke up this morning feeling great! I really appreciate everyone in this office for creating a pleasant experience for a person who really does not like going to the dentist!

I loved this office. I needed a new crown and my old office’s hours didn’t really work with my schedule. The great thing about Desert Inn Smiles is that they have later appointments so i am able to go after work and don’t have to take time off. Dr. RJ was great, very comforting and the process was quick and easy. They accept several insurances and the front office was very helpful. I’ll definitely return in the future

Rosy S. from Las Vegas, NV (Source: Yelp)

Desert Inn Smiles is a general, family, cosmetic, implant dentistry office in Las Vegas. Family owned and operated. We specialize in routine dental procedures such as cleanings (regular and deep cleanings), tooth colored composite fillings, crowns, bridges, root canal therapy, implants, and kid friendly dentistry! We love to provide a comfortable and affordable environment, and we take pride in the work that we do for our patients. Desert Inn Smiles has been in the works for many years, but finally coming to fruition in 2017. Dr. R.J. couldn't think of a better place to open a family dental practice, but at home! Born and raised in the city of Las Vegas, Dr. R.J. is a true local. He graduated from Cimarron-Memorial HS and completed his undergraduate and doctorate studies at UNLV. Since then, he has made it his focus to provide the very best quality dental care to all of his patients. He made the move to Dallas, TX for a few years, where he fell in love with BBQ and a beautiful lady named Audrey. They then made their way back to Las Vegas to open Desert Inn Smiles with the goal of caring for the city and the community through dental care. ​ Dr. R.J. has spent a lot of his time outside of practice furthering his skills by way of continuing education. He has taken numerous hours in many fields, but his primary focus for the past 5 years has been dental implantology, in which he has accumulated over 350 hours in the subject alone. He is an educator and is a part of the Implant Know-How team and the Wehrle Implant Immersion Course, in which he is an instructor.
