Excessive tooth decay, tooth infection, and crowding can all require a tooth extraction. Also, If a tooth has been broken or damaged by decay, our dentist will try to fix it with a filling, crown or other treatment. Sometimes, though, there’s too much damage for the tooth to be repaired. In this case, the tooth needs to be extracted. A very loose tooth also will require extraction if it can’t be saved, even with bone replacement surgery. Those who get braces may need one or two teeth removed to provide room for their other teeth as they shift into place.
