Signs a Filling or Crown May Need Attention
August 4, 2026
Dental fillings and crowns help repair or protect teeth affected by decay, damage, or wear. Although restorations are designed for regular use, they can gradually change as they are exposed to chewing forces, temperature changes, and daily habits. Not every unusual sensation means a restoration has failed, but certain changes are worth discussing with a dentist.
Sensitivity That Persists or Develops Suddenly
Some temporary sensitivity may occur after dental treatment. However, sensitivity that develops unexpectedly, keeps returning, becomes stronger, or lingers after eating or drinking should be assessed. Discomfort may be related to the restoration, the surrounding tooth, gum recession, decay, or another concern that cannot be identified from the symptom alone.
A Change in the Way Your Teeth Meet
A filling or crown that feels unusually high may affect how your upper and lower teeth come together. You may notice that one tooth contacts first, chewing feels uneven, or pressure is concentrated in a particular area. A change in your bite should be brought to your dentist’s attention, particularly when it causes discomfort while chewing.

Rough, Chipped, or Loose Areas
A rough edge, visible chip, crack, or movement in a restoration may indicate that it has been damaged or loosened. Food repeatedly collecting around the area, floss catching or tearing, or an unpleasant taste may also warrant an examination. Avoid trying to repair or reattach a loose restoration at home, since a dentist should first evaluate the tooth underneath.
Caring for Dental Restorations
Continue brushing twice daily with fluoride toothpaste and cleaning between your teeth. Avoid chewing ice, biting pens, or using your teeth to open packaging, as these habits can place unnecessary stress on both natural teeth and restorations. Patients who clench or grind should also discuss this with their dental team.
