Marlborough Office

Cosmetic Dentist in Marlborough MA

With cosmetic dentistry, we are able to improve our patients’ lives by giving them beautiful smiles they love to show off. For some patients, this enhancement enables them to gain confidence that helps them in their careers or in their social relationships. 

For other patients, it relieves the discomfort of always feeling like they need to cover their mouths with their hands. When they finally see their new smiles, it can be hard for them to stop smiling! Finally, they love smiling and laughing with their friends. Seeing a patient with a new, nonstop smile is one of the most delightful aspects of our job.

Your dentist keeps your teeth clean and healthy, but that’s not all a dentist can do. At Union Dental in Marlborough, we also pride ourselves in helping patients have the most attractive smiles. We want you to feel great about your appearance. Schedule a cosmetic dentist appointment with Dr Tony Tong to learn how you can improve your smile.

Tooth Whitening

It’s amazing the difference that lighter, brighter teeth can make. Many people have stains or discoloration. Even though that change is normal, you don’t have to resign yourself to it. Teeth whitening procedures can give you back your brilliant smile.


Our Union Dental team uses the Zoom! system for professional whitening. We have both in-office and at-home treatment options available. Some patients have seen improvements up to seven shades lighter than before. Our dental professionals will work with you to determine what type of whitening treatment will best suit your needs.

Dental Veneers

The most stubborn stains may not respond to teeth whitening as much as you'd like. Also, whitening can change the color of your teeth but not the shape. If you have cosmetic concerns that go beyond basic brightening treatments, we may suggest dental veneers.


Made of porcelain, veneers are designed to go over the front of your teeth. First, we remove a bit of your enamel to make space for these thin covers. Then, we bond the veneers to your teeth. It’s a permanent way to hide stains, chips, gaps and other irregularities.

Dental Crowns

Dental Veneers go on the front of your teeth. Crowns are similar, but they surround the whole tooth. We match them perfectly to your mouth in size, shape and color so that they look just like natural teeth.


Typically, crowns are recommended for patients whose teeth have been damaged. Crowns are also advised for many patients who have root canals.

Dental Bonding

Not all tooth concerns require a major procedure. Dental bonding is a quick way to solve many cosmetic issues. It’s a tooth-colored material that can fill gaps, make repairs or hide stains.


Who can benefit from dental bonding? We’ve used this service for people with:


  • Chips
  • Discoloration
  • Excess space between teeth
  • Short teeth
  • Unusual tooth shapes


Bonding can be done in just one visit.

Cavity Filling

Are you worried that getting a cavity filled will affect the look of your mouth? At Union Dental, that doesn't have to be a concern. We use tooth-colored fillings made of composite resin. No one will notice that you’ve had a cavity taken care of, and you won’t have to worry about the filling discoloring the surrounding area over time.


Dr Tony Tong and the team can even redo your old fillings. Ask us about having replacement fillings put in using tooth-colored material.

Full Service Dentistry

It’s great to have a cosmetic dentist on your side, but you also need a professional who can take care of your everyday dental needs and your serious oral health issues. In addition to cosmetic dentistry, Dr Tony Tong also provides general dentistry and oral surgery.


When you need a cleaning or an exam, visit our Union Dental office in Marlborough. You can also turn to us for root canals, extractions, implants, bridges and more. Of course, we’re always here for your whitening, brightening and repair needs. With our team on your side, your smile will be in good hands.
