Yes, dental bridges can increase the risk of tooth decay and gum disease because of how they are structured. The design of a bridge naturally creates small spaces where food debris and bacterial plaque can easily accumulate, specifically under the artificial tooth (the pontic) and around the anchor teeth (the abutment teeth).

If these areas are not meticulously cleaned, the trapped plaque can lead to several biological complications:

• Tooth Decay: Plaque buildup fuels cavities at the margins of the crowns. If decay reaches the nerve of an anchor tooth, it may require a root canal or lead to the loss of the entire bridge.
• Gum Disease: Bacteria around the bridge can trigger inflammation of the gums, known as periodontitis. This is a serious concern because gum disease and cavities are actually the leading causes of bridge failure, occurring more frequently than technical issues like material breakage.

Research cited by the American Dental Association highlights that these biological risks contribute to a 63% survival rate for bridges over a 25-year period. However, we treat each patient as we would our own family, and we have seen firsthand that these risks are manageable. The longevity of your bridge depends heavily on daily habits, such as using floss threaders or interdental brushes to clean under the restoration, and attending regular professional cleanings so we can catch early signs of inflammation or decay.
