Services We Provide

Dental Exams

Routine dental check ups can help to make sure that your teeth and gums are healthy.

Dental Cleanings

Plaque and bacterial calculus build-up occurs everyday. A dental cleaning uses specialized instruments to remove the bacterial collections to promote oral health.


Sealants are thin, tooth-colored, plastic material that is applied to the deep grooves to prevent cavities.

Fluoride Treatment

Fluoride is a natural occurring mineral that helps to strengthen and protect teeth from cavities. It also promotes the remineralization of decalcified teeth.

Kids’ Teeth

Baby teeth are just as important as adult teeth! Children should visit a dentist when they are as young as 6 months or 1 years old.

Deep Cleaning

Sometimes excess build up can collect at the gum line or roots. This can cause severe irritation. A deep cleaning can help bring your gums back to health!

Composite Fillings

When a tooth has a cavity, resin composites restorations (a tooth-colored material) is used to restore teeth.

Dentures and Partials

If you're missing multiple teeth, partials and dentures are a great way to help you restore your abilities to chew.


Implants are a great restorative option for missing teeth. After an implant integrates and heals, an implant crown needs to be placed to help restore function.


Large cavities and broken teeth can make a tooth weaker. Crowns can help protect your teeth from fracture.


Invisalign takes a modern approach to straightening teeth, using a custom-made series of aligners. These aligner trays are made of smooth, comfortable and virtually invisible plastic that you wear over your teeth.


Coffee, tea and wine can stain your teeth, leaving them looking old and dull. Our in-office and take-home trays will help to remove these stains for a younger fresh look!


When a cavity is extremely large, it can affect the nerve and cause pain or sensitivity. Root canals treatment removes the bacteria and damaged nerve.


Night guards are worn at night to help protect your teeth from trauma when you grind and clench.


We want to make sure you are comfortable, and nitrous oxide helps you relax!


Occasionally the best course of action is to extract a severely damaged tooth.


Dental emergencies happen, and we are prepared to treat time sensitive injuries.


Dental veneers can achieve your perfect smile. Veneers are a dental porcelain laminate, and are custom made just for your teeth.
