While dental composite restorations are generally safe and successful, complications can occasionally arise. It is important to be aware of these possibilities and seek prompt dental care if you experience any of the following:

1. Tooth Sensitivity: Sensitivity to hot or cold temperatures is common after dental composite restorations. It should subside within a few weeks. However, if the sensitivity persists or worsens, contact your dentist.
2. Discoloration: Composite restorations can stain over time, especially if you consume staining substances excessively. Your dentist may be able to polish or replace the restoration if severe discoloration occurs.
3. Chipping or Fracturing: Although composite restorations are durable, they can chip or fracture due to trauma or biting down on hard objects. If this happens, contact your dentist immediately.
4. Allergic Reactions: Although rare, some individuals may experience allergic reactions to the materials used in composite restorations. If you notice any unusual symptoms such as swelling, rash, or difficulty breathing, seek immediate medical attention.
5. Secondary Decay: Dental composite restorations can develop new decay around their margins if proper oral hygiene is not maintained. Regular brushing, flossing, and dental visits are crucial to prevent secondary decay.
