Wisdom teeth have lesions that interfere with normal life and need to be removed.

1. The best time to extract a tooth: 18 to 30 years old is the most suitable, the sooner you have symptoms, the better, after the age of 40 tooth extraction will increase the risk and difficulty of treatment.
2. Early tooth extraction is better: when wisdom teeth only have tooth germs, the damage of extraction is small, and when the root formation is incomplete, the tooth root is thicker and not easy to break.
3. Delay in tooth extraction wound is larger: Delay may lead to other lesions caused by impacted tooth, which will increase the difficulty of tooth extraction, slow wound healing, and increase the difficulty of treatment.
