How does a dentist fix your cavities?
Fixing cavities, also known as dental caries, typically involves several steps carried out by a dentist to remove the decayed portion of the tooth and restore its structural integrity and function. Here's a general overview of how a dentist might fix cavities:
1. Examination and Diagnosis:
- The dentist begins by examining your teeth to locate and assess the extent of the cavity. They may use dental instruments, such as a dental explorer and a dental mirror, to check for signs of decay.
- If necessary, the dentist might take X-rays to get a more detailed view of the tooth and the surrounding bone to determine the depth of the cavity and rule out any underlying issues.
2. Preparation:
- The dentist numbs the area around the affected tooth using a local anesthetic to ensure you are comfortable during the procedure.
- They then use dental tools, such as dental drills, to carefully remove the decayed part of the tooth. This step helps to eliminate bacteria and prevent the cavity from spreading further.
3. Cleaning:
- Once the decayed material has been removed, the dentist thoroughly cleans the area. They may rinse the tooth with water or use suction to remove any remaining debris.
4. Placing a Liner (Optional):
- In some cases, the dentist might apply a liner to the tooth before the final restoration. This is done if the cavity is deep and close to the pulp (the innermost part of the tooth). The liner helps protect the pulp and reduce sensitivity.
5. Restoration:
- After the tooth is prepared, the dentist restores its shape and function using various materials. Common options include:
- Dental Amalgam (Silver Fillings): These are durable and long-lasting, often used in molars and premolars.
- Composite Resin (Tooth-Colored Fillings): These can be matched to the color of your natural teeth and are used when aesthetics is a priority.
- Glass Ionomer Cement Fillings: These fillings release fluoride, which can help strengthen the tooth. They're often used in situations like pediatric dentistry.
- Ceramic Inlays or Onlays: In cases of larger cavities, the dentist might recommend a ceramic restoration that is custom-made to fit the tooth.
- Once the filling or restoration is in place, the dentist adjusts it to ensure a proper bite and smooth surface.
6. Polishing:
- Finally, the dentist polishes the restored tooth to smoothen any rough edges and provide a natural appearance.
It's worth noting that the specific techniques and materials used may vary based on the individual case, the extent of the cavity, and the dentist's professional judgment. It's important to follow the post-procedure care instructions provided by your dentist to ensure the longevity of your dental work.
