Honestly, Dr. Tu is amazing. She's super thorough and really takes pride in her work. She actually listens to my concerns, which is rare, and it's genuinely a pleasure to see her (because let's be real, who actually enjoys going to the dentist?). I love that she's thoughtful with treatment and doesn't push unnecessary stuff. Finally, a dentist in Sunnyvale I can fully trust! 10/5 stars — especially for cosmetic dentistry and general dentistry.
Owner Response
Thanks so much! Dr. Tu really does care about doing things right and making sure patients feel heard. At Bay Smile Design in Sunnyvale, we take pride in that. Glad you trust us — see you next time!

There's no one else I'd trust with my teeth besides Dr. Tu. She always explains what needs to be done so I understand how to keep my teeth healthy. Not only is she the best dentist, but the whole staff is super friendly. From Eva welcoming me and setting up appointments to Agnes doing my cleanings — everyone makes me feel like family. Agnes is gentle and patient with all my questions. I love this team and will be a patient for years to come. Their preventive care and teeth whitening services in Sunnyvale are top notch!
Owner Response
We really appreciate hearing this! Dr. Tu always takes time to explain things clearly, and Eva and Agnes will be thrilled to hear your kind words. It means a lot to know you feel comfortable here at Bay Smide Design in Sunnyvale. Looking forward to your next visit!

I'd strongly advise caution before choosing this clinic. The front desk staff was incredibly rude and unprofessional. The management seems disorganized, and there's zero transparency about pricing and procedures. It felt more like a business pushing unnecessary sales than a healthcare provider caring for a patient. Save your time and money — go somewhere else where patients are actually valued. I was looking for honest cosmetic dentistry and general dentistry in Sunnyvale, but this wasn't it.
Owner Response
We take patient care and transparency very seriously at Bay Smile Design in Sunnyvale. We are unable to locate a patient record under this name. If you received care here, please contact us directly so we can address your concerns and work toward a resolution.

Very disappointing experience at this clinic. From the moment I walked in, communication was subpar. The dentist lacked patience and didn't explain the treatment plan or costs clearly. I was looking for cosmetic dentistry and general dentistry in Sunnyvale, but left feeling confused and frustrated.
Owner Response
We take patient care and transparency seriously. After reviewing your review, we noticed similarities with others posted the same day from accounts with no other activity. If you are a patient at Bay Smile Design in Sunnyvale, please contact us so we can address your concerns.

Received a rushed cleaning — the hygienist left to get the dentist, who didn't even look in my mouth, just signed off on paperwork without making eye contact. On top of that, I was charged a premium fee because of their contract with my insurance. For teeth cleaning in Sunnyvale, I expected more thorough care.
Owner Response
Sorry to hear about your experience. The hygienist that day was a temporary provider while our regular is on maternity leave. We normally pride ourselves on thorough care at Bay Smile Design in Sunnyvale. We'd like to make it right — please give us a call.

After my filling, my face and lips swelled up, which never happened before. Then I got a viral mouth cold that made it worse. I was charged more than the pre-visit insurance estimate. The process felt rushed — long waits, and the doctor seemed reluctant to talk, just wanted to finish fast. Scheduling was chaotic — had to call multiple times with no resolution. Also felt like over-treatment: my previous dentist never recommended this. For general dentistry in Sunnyvale, I expected better.
Owner Response
We're sorry your experience wasn't smooth. Swelling can happen with deep decay, but we understand your frustration. At Bay Smile Design in Sunnyvale, we're reviewing our scheduling and communication to improve. Please contact us so we can discuss your concerns directly.

I've been coming to Dr. Lee and Dr. Tu's dentistry for years — convenient location, friendly staff, and excellent hygienists. They typically only recommend useful extras like fixing fillings or wisdom teeth extractions, but don't push them aggressively. For general dentistry and emergency dental services in Sunnyvale, they're the best. Highly recommended!
Owner Response
We're happy you appreciate our care and approach! Dr. Richard Lee and the whole team at Bay Smile Design in Sunnyvale are glad to have you as a longtime patient. See you at your next cleaning!

I recently had my wisdom teeth removed at Bay Smile Design, and honestly, it was a great experience. From start to finish, the team was professional, caring, and skilled. The procedure went smoothly, and I had minimal discomfort afterward. What really impressed me was the thoughtful follow-up to check on how I was doing — made me feel truly cared for. Not often you can say that about dental surgery, but it was awesome. If you need third molar extractions in Sunnyvale, go here!
Owner Response
So glad your wisdom teeth removal went smoothly! Our team at Bay Smile Design in Sunnyvale aims to make every patient feel comfortable and cared for. Thanks for recommending us — we appreciate your trust!

In late 2024, Dr. Tu said I needed 3 fillings and a crown. I got a second opinion, and that dentist said the tiny crack on my molar was common and crowning it would be 'completely unnecessary' and 'such a shame.' Also, two of the 'cavities' were just mild decay from having braces and not brushing well — not true cavities. So I only had one real cavity. Yet I was told I needed over two thousand dollars of work. Extremely disappointing. For general dentistry and cosmetic dentistry in Sunnyvale, I expected honesty.
Owner Response
Thank you for your feedback. We're sorry for the concern this caused. Treatment recommendations can vary between providers based on diagnostic approach. At Bay Smile Design in Sunnyvale, we aim for conservative care but sometimes deeper issues are only visible during treatment. We'd be happy to discuss further if you'd like.

I’ve been a loyal customer of this place with my family ever since I was in my little age (I wanna say ever since I was in fifth grade), and this place really takes care of you when it comes to your teeth. They really put forefront first what it means to be yourself. In the past, we’ve had no problem about setting up appointments for quarterly teeth cleanings, wisdom teeth removals, and more. The service at this dental place is phenomenal — I would recommend anybody needing a new dentist or hygiene place to check this one out. Not only do they have the best doctors like Dr. Tu and Dr. Lee, but they also have dental assistants that make sure every experience that you have is worthwhile. Thanks for always making my memories worthwhile!
Owner Response
Thank you for your kind words and for being such a loyal patient over the years! It’s truly an honor to have cared for you and your family since your school days.

Regular cleaning and exam appointment was setup quickly. Promptly met by the nurse to do a set of x-rays before the cleaning/exam started by the dentist. Overall experience was very attentive and professional, with clear communications of the dental health status, and area that needs to be monitored and looked at in the next scheduled cleaning/exam visit. Thumbs up!

Dr. Lee is a reliable professional. He had installed a dental implant for me in 2014. The implant is still functioning. Whenever I have any implant questions I always go to his clinic. He has been very helpful and I highly recommend him.
Owner Response

My wife came in to get two veneers on her front teeth. They have never lasted beyond two years and have struggled to keep them on. We’ve gotten a second review from a very expensive clinic on the east coast and they pointed out that the color was off, the bond was not properly done, and the veneers are now causing her to have gingivitis on her two front teeth. She has come in before to Bay Smile to have them fixed within 2 years of them being put in and we were charged again for the fix. I would have hoped they would have covered the cost to fix what was supposed to last 8-10 years. Incredibly frustrating and disheartening as a partner to watch my wife suffer through this heartache time and time again. Oh and she had to get them taken off originally at Bay Smile as the color was off. Not a very professional clinic. Good luck if you’re getting veneers here. I would go to a specialist instead of here.
Owner Response
Thank you for sharing your concerns. We’re truly sorry to hear about your wife’s experience and regret that it didn’t meet her expectations.

Amazing experience at Bay Smile Design! From the moment I walked in, the staff made me feel welcome, and they even texted me before my appointment. The front desk was efficient and friendly, got me checked in quick. The office is spacious, modern, clean with a calming vibe. I was nervous about my cleaning since I hadn't seen a dentist in over a year, but Dr. Tu put me at ease right away. She was professional, gentle, and took her time. If you need preventive care or teeth whitening in Sunnyvale, this is the place!
