### Common Problems with Dental Fillings **Tooth Sensitivity:** It's common to experience sensitivity to pressure, air, sweet foods, or temperature after getting a filling. This usually resolves on its own within a few weeks. Avoid triggers and pain relievers are generally not needed. If sensitivity persists beyond two to four weeks, consult your dentist. They may recommend desensitizing toothpaste, apply a desensitizing agent, or suggest a root canal. **Allergic Reactions:** Allergic reactions to silver fillings are rare, with fewer than 100 cases reported. Symptoms include skin rashes and itching. If confirmed, another restorative material can be used. **Wear and Tear:** Constant pressure from chewing, grinding, or clenching can cause fillings to wear away, chip, or crack. Your dentist can identify weaknesses during regular check-ups. **Decay Under Fillings:** If the seal between the tooth enamel and the filling breaks, food particles and bacteria can cause additional decay. Untreated decay can infect the dental pulp and cause an abscessed tooth. Extensive decay may require a crown instead of a replacement filling. **Filling Loss:** New fillings may fall out due to inadequate dental work, contamination, or bite trauma. Older restorations are usually lost due to decay or fracturing of the remaining tooth.
