1.Why do teeth need extracting? When a tooth has been damaged either by infection (from tooth decay) or trauma (from a knock or bump), the dental professional will provide advice as to the best treatment for the tooth. If the damage to the tooth is too great, the best option may be to extract the tooth. 

2. How are baby teeth extracted? The dental professional may take x-rays of the affected tooth to assess the position of the tooth, the surrounding bone and the presence of an adult tooth. The tooth and surrounding area will be numbed (an injection) by local anaesthetic. Once the area around the tooth is numb, the tooth is loosened with movements and pressure. The loosened tooth is then removed. Following an extraction, the patient will be asked to bite down on a piece of sterile gauze to help stop the bleeding.
