Dental bridges are a popular and effective way to replace missing teeth. When well cared for, they can restore your smile, improve chewing function, and last up to 15 years—or even longer. But like any dental restoration, a bridge isn’t invincible.
Knowing what can cause a dental bridge to fail can help you take the right steps to protect your investment and maintain a strong, healthy smile for years to come.
Poor Oral Hygiene
One of the most common reasons a dental bridge fails is poor oral hygiene. While the bridge itself can’t decay, the natural teeth that support it—called abutment teeth—can still develop cavities or gum disease. If these teeth become compromised, the bridge can loosen or fail entirely.
Brushing twice a day, flossing daily (especially around and under the bridge), and using an antibacterial mouthwash can go a long way in preventing plaque buildup and keeping your supporting teeth strong.
Bite Problems or Excessive Pressure
Dental bridges are designed to withstand normal biting and chewing forces, but excessive pressure—like grinding or clenching your teeth—can cause them to crack, loosen, or wear down prematurely. If you tend to grind your teeth at night, a custom nightguard can protect both your natural teeth and your restoration from damage.
It’s also important to have your bite alignment checked regularly. An uneven bite can place extra stress on the bridge and lead to long-term failure if not addressed.
Gum Disease and Bone Loss
Healthy gums and bone are essential to supporting a dental bridge. If gum disease develops and isn’t treated promptly, it can cause the supporting bone to deteriorate. As a result, the abutment teeth may loosen, and the bridge may no longer fit properly.
Early gum disease may not cause pain, but signs like bleeding gums, bad breath, or gum recession should never be ignored. Regular dental cleanings and checkups are crucial for catching these problems early and preventing long-term damage.
Decay Under the Bridge
Although the bridge covers the tooth structure, bacteria can still sneak in through small gaps if the bridge isn’t sealed properly or if decay develops near the margin. Once decay begins under a crown or abutment tooth, it can compromise the stability of the entire bridge.
To avoid this issue, it’s essential to schedule regular dental visits so your dentist can monitor your bridge and identify any signs of trouble early on.
Wear and Tear Over Time
Even with excellent care, all dental restorations experience natural wear and tear. Over the years, materials may become worn, and fit may change due to shifting teeth or jawbone changes. That’s why long-term maintenance is key—your dentist may recommend occasional adjustments or eventual replacement as your needs change.
Understanding what leads to dental bridge failure helps you take proactive steps to protect your smile and extend the life of your restoration.
