Wisdom tooth has cavity and infected how do you fix it?

Treatment options for an infected wisdom tooth with a cavity include:

1. Root canal therapy: This involves removing the infected pulp and nerve of the tooth and then filling and sealing the root canals to prevent further infection. A root canal can relieve pain and save the tooth from extraction.

2. Tooth extraction: If the infection is severe or the tooth is badly damaged, extraction may be the only viable option. This is usually done by an oral surgeon and may require stitches to close the wound.

3. Antibiotics: Antibiotics may be prescribed to help fight the infection and reduce pain and swelling.

4. Pain relievers: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can be used to manage pain.

It's important to see a dentist or oral surgeon as soon as possible if you have an infected wisdom tooth to get the proper treatment and prevent complications.
