Sean C Lee, DDS

Kind and knowledgeable. Clearly explained all procedures being done. Will go back when my next cleaning is due.

Dr. Lee & his staff are WONDERFUL & they do a FANTASTIC job! I have very sensitive teeth & they take great care in making me comfortable. LOVE EM!

Sean Lee is a very personable and ethical doc who goes the extra mile to spend time with you. Had a routine exam and cleaning which was not painful — very good hands!

Dr. Sean C. Lee is awesome! He is extremely knowledgeable, caring, friendly and listens to the needs of his patients. I had two crowns put in a little over six months ago and I have not had any problems. His work is impeccable! His staff is friendly, helpful and caring as well. I did a lot of research to find a new dentist and Dr. Lee got such great reviews and had high credentials so I decided to schedule an appointment. I am so glad I did. If you are looking for an all-​around amazing dentist, give Dr. Lee a call. He’s the best!

First off, I generally have really bad anxiety when it comes to the dentist, I was with my past dentist for about 12 years and finally decided that I needed to look for a new one. And if you were like me, you’re doing the online research, reading through reviews on Google and Unilocal (like this review). After comparing a few dentists, I opted for Dr Sean Lee.
I walked into the office and it was definitely a different vibe from other offices, Dr Lee was already standing there finishing up with another patient, the girls behind the counter looked happy to be there, I filled out my paperwork and I was ready to go for xrays
Everything was very up to date, I was pleasantly surprised with the xrays, they were digital, the tabs weren’t as uncomfortable as the old school ones that the assistant usually jabs in your mouth, and you can see the xrays right away
Sean and I believe Janet? (I feel bad for forgetting her name :(but I know her last name is graham) had a great dynamic, they kept a good atmosphere, they were joking and talking and it wasn’t too awkward like it usually is at a dentist.
Sean does like to talk a lot, which is cool cause I usually talk a ton too, I would have been responding right back if it wasn’t for the fact that my teeth were getting cleaned haha, he makes sure you’re doing alright and not in pain, and he explains everything very thoroughly, you can tell he actually cares about he patient and on a side note will even ask if he talks too much haha
Great atmosphere, and great people. I set up my next appointment right when I walked out. I don’t think I’ll be having any dental anxiety anymore!

This dentist and staff are amazing! I have been to the same dentist since I was five years old and considered a fact of life that all dentists are mean and don’t really care about you. But I was very happy to learn this dentist was nothing like my old dentist. They seem as though they genuinely care about their patients. Dr. Lee is unlike other dentists because he doesn’t pressure you to begin work or buy certain products to make money. Instead he makes suggestions and allows you to decide if it works for you. He and his staff treat their patients very kindly and try their best to work with you and your schedule without pressure. I WOULD DEFINITELY RECOMMEND THEM TO ANYONE!!!

My husband is the absolute worst when it comes to visiting the dentist. He was years overdue and needed dental care badly. I felt that my personal dentist did not have the bedside manner that would calm my husband’s fears. I went on a mission to find the perfect dentist that could handle my husband as if he were a 5 year old. It took several weeks before discovering Dr. Sean Lee. The minute I walked into his office I had the feeling of success! He and his staff are the sweetest and most professional dental group I’d ever encountered. My husband is so happy and actually looks forward to each appointment. Needless to say, I left my former dentist in Pasadena for Dr. Sean Lee!

Went there recently for my 6 month check up and as always I’ve been treated with the utmost respect and the environment is very friendly and clean. Dr. Sean Lee is my dentist and every time I go there he explains the procedure of what he’s about to do. He’s also open to any and all questions. He’s very informative and knowledgeable. His assistants Debbie and Danielle are very friendly, helpful and very professional as well. Overall the staff is trustworthy and on my first visit even received my bleaching kit and have received addtional bleaching kits since. Would highly recommend without a doubt.

Dr. Lee and his staff are one of a kind. Truly talented and professional people. They always make me feel welcomed and relaxed. Dr. Lee has seen both my children, 3 years old and 5 years old, and they have had a great experience. I have a seen a few dentist over my life and Dr. Lee is by far the best one.

Enjoyable experience and relaxing atmosphere. Dr lee is very informative, an genuinely cares about you. His whole staff are very nice. I had my teeth cleaned and e was very careful around the sensitive areas of my mouth. I would definitely recommend him to anyone looking to have any kind of dental work done.

I highly recommend Dr. Sean Lee. He is professional and trustworthy. I always look forward to our visits. My five year old son absolutely loves going to his check ups. Dr. Lee and his staff have created an environment that is non threatening for patients of all ages. Dr. Lee is always on schedule with his appointments and usually only has one patient at a time and you really can tell he cares about his patients. He always explains in great detail what he is going to do and why. His office is also in a great location in Upland and the office is always clean. I have had some bad dentists in the past so finding Dr. Lee was a treasure. Thank you!

Surroundings comfortable…
Dr. Lee… Priceless…

The nicest dentist I have ever had! The office was easy to find and clean. Everyone was very welcoming and friendly. It is not often you find a doctor who actually takes the time to explain everything to you and make you aware of all issues so you can make an informed decision. So glad I started going to Sean Lee!

This is a update: had my teeth cleaned. It was great, smooth, no pain, none of that scraping I would always dread. He is up to date in the Dental field. Talks to you, explains before and during what –why he is doing what he is doing. Great staff.
I tell everybody about him because somebody is always in need of a good dentist
and it’s by word of mouth, personal experience that we look for as to who we
we will call. Thats how I first found him, thru a friend who also had good things
to say about him.

So glad I found Dr. Lee, so sad that I have to move from the area.
I’ve always felt a lot of guilt and shame about my teeth from dentists in my past due to numerous cavities. After a while I stopped even trying to floss because I felt like it was a waste of time.
When I went to Dr. Lee’s office, all that changed.
Dr. Lee was incredibly attentive, intelligent, friendly, patient. I can’t say enough good things about him. From the moment he came in to look at my teeth and x-​rays, I just felt very welcome and put at ease. So many businesses don’t realize how important a first impression is, but my experience at Dr. Lee’s office exemplifies good first impression. His mantra that he treats you «like family» is certainly true.
He told me that on a scale of 1 to 10 for teeth health, my teeth were about a 9.5. I was floored! I felt reinvigorated to take good care of my teeth, and have begun flossing again (still gotta start brushing twice a day). He answered all of my questions in detail («which is more important: genetic teeth health or teeth care/​hygiene?») and made sure to set me up with a good plan before leaving.
He didn’t force any cavity fillings or teeth work on me before leaving, which was incredible. He told me what I should watch out for in my mouth (a couple trouble spots), and recommended where to go to get my wisdom teeth removed.
I left feeling really sad — I wanted to keep hanging out with Dr. Lee! I’m a young man, and so I’ve had bad dentist experiences all my life. Dr. Lee turned all of that around.
I can’t recommend Dr. Lee highly enough, and I feel like this looks like some kind of paid advertisement. But really, if you’re looking for an attentive, honest, and caring dentist in a comforting and relaxing atmosphere, then please have your teeth cared for by Dr. Sean Lee.

Dr. Lee and his team are excellent! He gives you the time and care needed for to have a really enjoyable experience, I’m serious! I enjoy going to my cleanings because Dr. Lee knows me by name and although I only come in twice a year he still remembers the conversation we had six months before. I’m a bit of a wimp when it comes to drilling but Dr. Lee accommodates to me and my sensitive mouth.
