Modern composite fillings blend seamlessly with your natural teeth while restoring strength, function, and appearance.

Typically, when something is repaired, it’s restored to its former appearance. For example, if someone fixes a dent or scrape on a car, the person performing the repair paints the formerly damaged area the same color as the rest of the car. In other words, repairs don’t usually stand out. So why would the approach to repairing a damaged or decayed tooth be any different?


New Holland’s Dr. Laura Harkin takes a forward-thinking approach to dental care. To restore teeth compromised by decay or damage, she uses durable, long-lasting, tooth-colored fillings. There’s no metal to mar your smile and advertise your dental work to the world.


Out with the Old

For decades, silver fillings were used to fill cavities. The material is actually a mixture of different metals and substances, including mercury. As people began questioning the safety of mercury-containing fillings, an alternative emerged: composite resin tinted to match natural tooth color. This alternative not only provided an aesthetic choice for patients, but it delivered unmatched durability.


Metal fillings can move over time, expanding and contracting in response to the temperatures of the foods and beverages we consume. As a result, tiny cracks can form. Bacteria can gain entry to the inner chambers of a tooth through these cracks and further damage the tooth.


In with the New

Dr. Harkin fills decayed teeth with composite resin. She also replaces old metal fillings with new tooth-colored ones. The resin starts out soft, so it can be molded to the contours of the prepared tooth. Plus, it can be tinted to blend seamlessly with your smile. When hardened with a special light, the material forms an impenetrable bond against future decay. Composite resin fillings won’t change shape over time, so they maintain their integrity for the long haul, protecting your smile.


White fillings repair dental damage to turn back the clock on your smile. Others won’t notice your fillings, but they will notice your beautiful smile.
