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

I have been a patient at this office for over 20 years. In March my dentist retired and the practice was turned over to Dr. Lily Du. She is fantastic and I couldn’t be more pleased! The staff is friendly and approachable. Dr. Du is enthusiastic and knowledgeable. You can tell she is passionate about what she does. I would highly recommend this practice and hope to continue as a client for an additional 20 years and beyond.

From the first time to everytime we come for a visit, the staff is so friendly. It feels like you’re with friends and family, its so welcoming. And Dr. Du is just the best, she worked with me today with patience and grace, even though my mouth wasn’t numbing. We got it eventually and they were sure to keep checking on me to ensure I was comfortable and safe. I love this office and the people in it are truly wonderful! Thanks for giving me my Ideal Smile!

My appointment was great. Dr. Du is a thorough professional who clearly keeps a modern and up-to-date practice. The entire experience was better than I have come to expect at other dentists. The office is a delight to be in – bright and nicely decorated. The staff are attentive, friendly, and diverse!

I highly recommend this place! Life got busy and I hadn’t been to a dentist in 4 years, at least… I was super nervous to go back! I found this place through Google so I was a little unsure of what to expect but the staff were so welcoming and understanding and didn’t make me feel bad about having not been in so long at all. They explained everything they were doing and were so gentle and patient with me. The office is also super adorable and beautifully decorated in a calming way. I’m actually looking forward to going back soon!

Filling popped out at 11pm on a Friday. Thought I was a goner for the weekend. Called in at 8:30 am on Saturday they fit me in at 10am. Was able to do all my paperwork online prior to arrival. Check in was a breeze i was taken to the chair within minutes of arrival. Hygienist was very warm and welcoming doctor was helpful energetic and kind. Couldn’t have asked for a better emergency dental appointment. I was a new patient and they treated me like a regular.

I’m from out of state, I needed emergency work done and I found this place. They did an amazing job, they were quick to get me in last minute. All the staff were so kind and sweet honestly this is the best dentist office that I’ve ever been to. I’m just disappointed that we don’t have a dentist office like this in California. I’m definitely going to see them if I need to while I’m in Washington. If your looking for excellent customer service this is the place for you. Thank you so much Dr. Du and Steph.

I have been visiting this dental office for almost two decades and have no reason to change. Even when my insurance situation changes, I look for a way to continue visiting this office. Dr. LaBounty and now Dr. Du have always given my teeth great care and attention. But that’s not all. Their hygienists and office staff have been just as attentive, friendly, and have always found a way to accommodate my schedule.

Dr. Du, Bebe, and the whole team are so welcoming, kind and empathetic. I especially love Dr. DU’s holistic approach to medicine, and the transparency around treatment planning and cost/insurance coverage. Establishing care as a new patient can sometimes be a daunting process, but the Ideal Smiles team have made me feel confident that I’ve made the right choice for a new provider.

Found Dr. Lily Du / Ideal Smiles through google search and I can’t be happier! Dr. Du really sets the tone for her practice to educate and communicate with patients and I love that. You can tell she loves being a dentist and truly cares about your oral health. Both Dr. Du and Bibi (hygienist) we’re super sweet and had gentle hands. I highly recommend!

New patient visit of Dr. Du and it was a wonderful first visit! She is warm, easy to talk to and great with explaining everything in detail. Stephanie and office staff are friendly and welcoming! Definitely would recommend to anyone looking for a new dentist in the Bellevue area ??

In March of 2020, my dentist retired and the practice was turned over to Dr. Lily Du of Ideal Smiles. The transition was seamless and I am extremely pleased with Dr. Du and her staff. They are friendly, approachable and knowledgeable. They make going to the dentist a joy…which is saying a lot! I would highly recommend this practice to anyone looking for a dentist.

Dr. Du and her staff are incredibly professional, welcoming, friendly, and any other positive adjective you could use. My recent visit with them was my first dental exam in quite some time and I had a lot of hesitance about what to expect. Thankfully, everyone in Ideal Smiles put my mind at ease. Dr. Du and Becky were fantastic in sharing their specific findings with my exam, rationale for their care, and current evidence in dentistry. They addressed my concerns, provided options, and created an environment for patient-centered collaboration—all of which are critical in effective health care. I can’t recommend them enough.

Dr. Lily is the BEST dentist around. She truly cares about her patients! During your visit with her you will feel her passion for dentistry and caring for her patients. She has a gentle touch & is very thorough in her explanations. She helped me with my moms difficult extraction case & even made time to squeeze her Into her busy schedule. Dr. Lily handled it with AMAZING care and my mom is no longer fearful of the dentist anymore. I am so thankful for the way the team cared for my mother. From the time you enter to the time you leave you will be greeted with warm smiles and helping hands. If your looking for a 5 star dentist! Ideal Smiles is a great choice. The entire team is amazing!

I had the opportunity to shadow Dr. Du and her team at Ideal Smiles. While watching the team in action, it became really evident that the Ideal Smiles crew love what they do! They love their patients, they love practicing dentistry, and (*really important point*) they love each other. This team dynamic fosters a wonderful environment for patient care that is both excellent and welcoming (and the Disney-themed decor is the extra cherry on top as well! haha). Thanks, Ideal Smiles!
