Tooth extraction is a common dental procedure, but the cost can be a barrier to tooth extraction. Through community dental programs, government dental assistance programs, free services from dental schools, and participation in oral health programs organized by volunteers, you can find free channels and methods for tooth extraction. The necessity of tooth extraction lies in relieving pain, preventing infection, and maintaining oral health. After tooth extraction, it is crucial to follow the doctor's recommendations, control bleeding, regulate oral hygiene, avoid eating hard foods, and return to your doctor's office regularly.
