Our general dentistry services include:

We recommend scheduling a dental cleaning at least twice a year to help maintain your dental and oral health. Our registered dental hygienists will remove plaque and tartar deposits in order to prevent cavities. We will also check for any signs of periodontal disease, oral cancer or any other abnormalities and finish off by polishing and flossing your teeth.

Drs. Doug & Cathy Smith are proud to use KaVo DIAGNOdent, dentistry’s most accurate aid for detecting cavities. The device features a small laser that detects decay in pits and grooves on teeth. This early detection results in smaller fillings and helps preserve your natural tooth structure. It is a simple, fast and painless way to maintain strong and healthy teeth.

We understand that many patients may feel uneasy about dental x-rays due to radiation exposure. Our practice has the most up-to-date x-ray equipment that exposes you to the least amount of radiation possible. X-rays allow us to detect hidden decay, determine the condition of current fillings, crowns and bridges, monitor wisdom teeth and so much more.

Root canals are needed when a tooth becomes diseased or inflamed. The procedure repairs and saves teeth that are badly damaged from a large cavity or major trauma. First, the infected pulp is removed and the tooth’s interior is cleaned and disinfected. The tooth is then sealed with a rubber-like material and restored with a crown or filling to prevent future infections.

Dental sealants are thin, plastic coatings that are painted on the surface of your teeth. They are most commonly painted on your back teeth (molars) to help prevent tooth decay. Sealants quickly bond to the grooves of your teeth and act as a protective barrier over the enamel.

Fillings restore form and function to teeth after decay is removed. Tooth-colored composite resin is the most common filling material used. It is a safe restorative material that will help you maintain a healthy mouth.

Full and partial dentures are reliable options to replace missing teeth. Our practice is equipped to create custom dentures to comfortably fit your mouth. We will educate you on the proper way to take care of and preserve your dentures.

Nitrous oxide is a gas you can breathe in to help you eliminate dental anxiety and feel more comfortable. It has no color or smell and is a very safe sedation. Our staff is trained to administer nitrous oxide if you believe it’s an appropriate measure to take in order to feel more at ease.

Oral cancers often go unnoticed because there is limited pain and physical evidence during the early stages. We will perform a thorough examination to identify any signs of oral cancer and determine the best solution to eliminate it. Oral cancer does not just affect tobacco users so everyone needs to be checked on a regular basis for any signs of the disease.

Drs. Doug & Cathy Smith have the tools and experience necessary to perform all types of cosmetic dental restorations.
