Porcelain Veneers

Porcelain Veneers Learn More

Veneers are very thin porcelain pieces that are custom made to adhere directly to the front of teeth without grinding or shaving. Transform your smile without drilling on your natural teeth!

In the hands of a highly skilled dentist, porcelain laminates can provide you with an incredibly natural, beautiful smile. They are virtually undetectable and can dramatically improve your appearance. They are durable and long-lasting when compared to other cosmetic treatments.

One-Visit Crowns

Porcelain Crowns Learn More

Protect and keep badly decayed or fractured teeth while maintaining a beautiful smile. Made to perfectly match the shape and shade of your other teeth, they’re durable, strong, and undetectable.

Crowns should be placed before the tooth is so decayed that it may fracture. This can often help prevent the expense of root canal therapy in the future. If a tooth is too damaged to have a crown applied, a porcelain bridge may be a good alternative.


Mercury-Free Learn More

The common silver filling contains mercury. Dr. Smith uses the highest-quality biocompatible, tooth-colored restorations to create healthy, beautiful smiles. Since the composite material adheres directly to the tooth enamel, less preparation of the tooth is required before using it. This means it is more durable and provides a more natural-looking result.

Smile Whitening

Smile Whitening Learn More

Many everyday things like coffee, tea and wine can significantly dull teeth. Smile whitening enables us to significantly brighten your smile for that dazzling white smile you deserve.

Plastic whitening trays will be made from models of your teeth. You will then place a special whitening gel in each tray and wear the trays in your mouth for several hours per day. (Many patients wear their trays after dinner and before bed.) A significant change in tooth color is usually seen in just four to six weeks.

Laser Dentistry

Laser Dentistry Learn More

Laser dentistry is a highly-effective, gentle way to treat gum disease, remove bacteria, and re-contour gum lines after cosmetic dentistry. Laser dentistry is a more comfortable, accurate way to produce excellent results.
