Normally, extraction is recommended when the tooth cannot be cured by root canal treatment or gum treatment. Keeping of natural teeth as long as possible is definitely better than replace them with artificial tooth.
Wisdom tooth is the tooth that cannot erupt properly. It usually occurs during the age of 18 – 25 years old. It might erupt straightly, inclinedly or horizontally and usually attach with the adjacent teeth and then cause difficulty in cleaning and make the teeth easily decayed and the gum nearby infected. Sometimes it might cause severe pain and terrible swelling.
