A dental filling is used to strengthen a tooth that is weakened due to cavities, cracks, chips or other reasons. The goal is to preserve the tooth and avoid extraction. It can also protect the tooth from future damage or decay.
Dr. Donald Reid offers amalgam free dentistry for your overall health and better aesthetics when placing a dental filling. Truckee CA dentist, Dr. Reid recommends that old silver, amalgam fillings be removed and replaced with composite, resin fillings, or “white” fillings, to improve the look and health of your smile.
In addition to the developing health concerns about the amount of mercury in amalgam, this type of filling can create dental problems down the road due to the nature of the material and how they are placed.
Amalgam fillings are placed in the tooth after decay has been removed, leaving a hairline opening around the edge. This is done because the material in amalgam will react to changes in temperature, space is left to accommodate expansion and contraction of the metals. This continuous expansion and shrinkage with temperature can easily initiate cracks and fractures in your teeth over time- and frequently does. Typical signs are increased tooth sensitivity as the forces of biting put pressure in the cracks and damage the tooth.
The break down of amalgam fillings over time enables the materials in them, such as mercury, to leak out and enter your body. The effects of mercury on overall health can be wide ranging, but exposure to toxic metals like mercury can have neurological and physiological effects that are lasting.
While the studies are ongoing in regards to the health risks associated with the use of mercury in dentistry, Dr. Reid has chosen to treat on the side of caution with composite fillings that will also enhance your smile.
Benefits of Mercury Free Fillings
Dr. Reid uses high quality, composite resin or porcelain for dental fillings. He expertly matches the material as closely as possible to your natural teeth for a beautiful result that will restore your oral health after damage or decay.
The procedure for placing a composite, or white filling is less invasive and requires the removal of as little tooth structure as necessary to address any infection or decay. The material is flexible and creates a permanent seal when cured, keeping out harmful bacteria and reducing the risk of future cracks as a result of biting forces because it remains stable despite temperature changes.
Dr. Reid can place most composite fillings during a single visit, and even places high quality porcelain fillings in one visit using CEREC technology. You will be made as comfortable as possible with a local anesthetic and relaxing surroundings while your tooth is prepared, filled and polished for a beautiful result.
Inlays & Onlays
If the tooth affected by damage or decay is a larger tooth, or if the decay is substantial and a larger part of the tooth structure needs to be removed before filling, Dr. Reid may recommend an inlay or onlay. This type of dental restoration is often called a partial crown and is typically made of high quality porcelain for a lasting result that will strengthen the tooth and prevent further damage.
