Come take advantage of our modern dental facility located in Upland CA providing excellence in modern dentistry.
E-Max / Obsidian (Lithium Disilicate, Lithium Silicate) crowns are considered one of the most esthetic crowns available today. They are a type of all-ceramic dental crowns which are preferred for its translucency, longer lasting aesthetic qualities. This type of crown is often used for a highly attractive appearance which ensures that they compliment the rest of your teeth.
Dr. Lee can surgically place implants into the bone to act as tooth root substitutes. If you have adequate bone levels and density, are generally not prone to infection and can maintain stringent oral hygiene - then you're the perfect candidate for dental implants. At Signature Dental, we only restore the highest quality implants from the most reputable companies such as Ankylos, Astra, Hiossen, Nobel Biocare, and Zimmer Biomet.
Cosmetic dentists know that the most esthetic veneers are also the ones that involve a certain degree of modification to the natural enamel of teeth. In most cases, 6 to 10 teeth on an arch are artistically shaped to ideal contours so that a thin porcelain veneer can be bonded in a harmonious balance between form and function.

We have been using these dentists for over 10 years. They are kind, efficient and professional. Usually, I am in and out in 35 minutes for cleanings. I’ve had one referral where the dentist found a tissue lump and wanted it checked by an oral surgeon. All was well, but I appreciated the concern. Thank you so much.

What a WONDERFUL Dentistry! From the front desk to the dental assistant(s) to the dentist(s). This group is very warm, inviting and professional at all levels. My standards are very high due to "lots" of inherited teeth issues so when I endorse a dentist that's pretty big. Thank you Signature Dental for taking such good care of your patients.

I went to Dr. Lee at Signature Dental for a consultation (2nd opinion). Lets just say he was so kind and professional. I had a bridge done with my previous dentist and am in excruciating pain due to my bite being off. Thanks to Dr. Lee I left with the knowledge and confidence needed to feel secure enough to be firm about having the bridge redone at my previous dental office. My entire family will now he going to Dr. Lee and Dr. Chan for all further treatment. The entire staff was amazing!

This place is not trustworthy just like some other dental offices I've visited before. It was some time ago, so I can't be sure if the same staff works there. The lady at the front desk was a total fake, pretending to be friendly. On the next visit, she even put the wrong tooth number on the chart before giving it to the dentist. If I didn't correct her, the dentist could have fixed a wrong tooth. I got treatments from both male and female dentists, a couple. I felt like they wanted as much $ as possible from my insurance maximum, suggesting me all kinds of unnecessary procedures. There are other

Everyone in this office is the cream of the crop! Absolutely wonderful and caring team. Never thought I’d get homesick for the dentist, but it’s honestly like going to see long-time friends when I go here- and I’ve only been twice! Makes it much easier to stay on top of my dental care, knowing I’m going to an appointment where I laugh a lot and feel like I’m their number one concern. For those who are needle averse, the injections here are fairly painless. Much, much better that other places I’ve gone.

These folks are great and know what they are doing. Super clean and nice place, cool gadgets. I like how the dentists show you everything and explain everything. Last cavity I had was about 8 years ago, get my cleanings frequently because I intend to keep them til I'm 98.
