### Everything You Need to Know About Dental Fillings Dental fillings are used to treat cavities and repair damaged teeth. Here's a step-by-step guide on what to expect: 1. **Diagnosis and Preparation**: Your dentist will first numb the area around the affected tooth with a local anesthetic. Then, they will remove the decayed part of the tooth using a drill, air abrasion instrument, or laser. 2. **Cleaning**: After removing the decay, the dentist will clean the cavity to remove bacteria and debris. If the decay is near the root, a liner may be placed to protect the nerve. 3. **Filling the Tooth**: The filling material is then applied. For tooth-colored fillings, the material is applied in layers and each layer is hardened with a special light. The dentist will then shape and polish the filling. 4. **Types of Fillings**: Fillings can be made from various materials including gold, porcelain, silver amalgam, composite resin, and glass ionomer. The choice depends on the location and extent of the decay, cost, and your dentist's recommendation. 5. **Indirect Fillings**: These are made in a dental lab and require two visits. They are used when not enough tooth structure remains to support a filling but the tooth is not so damaged that it needs a crown. 6. **Temporary Fillings**: These are used in certain situations and are not meant to last. They need to be replaced with a permanent filling to avoid complications. 7. **Maintenance**: Good oral hygiene is essential. Visit your dentist regularly, brush with fluoride toothpaste, floss, and use antibacterial mouthwash. If you notice any issues with your filling, contact your dentist. 8. **Pain and Sensitivity**: Some sensitivity is normal after getting a filling. If it persists, consult your dentist. Pain when biting may indicate that the filling needs adjustment. 9. **Allergic Reactions**: Rarely, some people may be allergic to the materials used in fillings. Symptoms include skin rashes and itching. 10. **Deteriorating Fillings**: Fillings can wear down over time due to chewing and grinding. Regular check-ups can help identify and address any issues early. By following these guidelines, you can ensure that your dental fillings last and keep your teeth healthy.
