Tooth extraction is performed only when the dentist finds out that pulling it out can improve oral health of the patient. Tooth decay, crowding and risk of dental infection are some of the common reasons for tooth extraction. Dentists make a note of the medical condition of the patient before performing tooth extraction. It is a process done with the help of local anesthesia. Depending on the complexity of the extraction process a surgery may sometimes be necessary. Dentists guide patients on post operation care which helps in quick recovery from the treatment. Pain medicines and ice bags can help reduce pain and avoid swelling after the process is complete.
