Our Services


Cosmetic Dentistry

Whether your teeth are the wrong shape, crooked, stained, or chipped, our cosmetic dentists can treat your teeth with minimal methods using the latest techniques and the finest materials.



Preventative Care

Efficient preventative care is key to having a healthy smile. Consistent checkups will allow our team to diagnose oral cancer, gum disease, and tooth decay before they spread and become a problem.  



Teeth Whitening

Teeth can become stained from the foods we eat and drink. A great way to bring back the brilliance and radiance of your smile is with Teeth Whitening treatments. In-office bleach treatments and at-home whitening custom trays are available options. 




General Routine Cleanings

Our dental health care professionals perform regular 3, 4 & 6 month routine dental cleanings. Maintaining a regular schedule for your oral health is an excellent way to avoid future gum issues and minimize carries from occurring.

Crowns, Bridges and General Dental

 Each case has its own recommended treatment. Crowns, bridges and composite (aka white) fillings are a few options when it comes to dental restorations. Make an appointment today and we can get you set up with a treatment plan. 

Missing Tooth Replacements

 Prosthetic replacements such as dentures, partial dentures and stay-plates/ flippers, are available for patients depending on current oral health and appropriate determination by the dentist. A detailed treatment plan is available to determine options for teeth replacements. 

Dental Implant Restorations

 Don't know where to start with dental implants? No problem, we work with and refer to some of the best specialists in the area. Dr. Grammas takes pride in excellent restorations for your implants, using only the best labs. 

Cosmetic Crowns and Veneers

 Cosmetic Dentistry is a great way to make changes to your smile, in the most natural appearing way possible. You chose everything from the size, shape to color of your teeth. Give us a call to make your appointment for a treatment plan today!
