Can Dental Bridges Increase the Risk of Tooth Decay or Gum Disease?

Yes, dental bridges can increase the risk of both tooth decay and gum disease if not meticulously maintained. While bridges are a common restorative choice, they present specific biological challenges that require daily attention.

Here is how these risks typically develop:

• Decay at the Margins: To anchor a bridge, we must reshape the healthy adjacent teeth (abutment teeth), which permanently removes protective enamel. The junction where the bridge crown meets the tooth is highly susceptible to plaque buildup. If bacteria reach this junction, decay can advance rapidly underneath the crown, often going unnoticed until the tooth is severely compromised.
• Periodontal Issues: Food debris and bacteria easily become trapped in the small space beneath the pontic (the fake replacement tooth). Without diligent cleaning, these areas can develop periodontal pockets and inflammation, leading to gum disease. According to research cited by the ADA, biological complications like caries and periodontitis are the leading causes of abutment tooth loss.

At our clinic, we provide a judgement-free space to help you manage these risks. Because cleaning under a bridge is more demanding than cleaning natural teeth, we recommend using special tools such as floss threaders, interdental brushes, or water flossers to reach difficult areas. Regular professional cleanings every three to six months are also essential so we can monitor the health of your supporting teeth and catch any early signs of inflammation or loosening.
