Tooth extraction may be necessary to remove a tooth loosened by gum disease, or one that has extensive decay or suffered damage. It may also be required for an impacted wisdom tooth or if you need more room for orthodontic treatment. Extracting teeth can help to eliminate pain and prevent infection.
You should promote healing after an extraction by eating softer foods and chewing on the opposite side of your mouth. You should also avoid hot foods, smoking and alcohol. The site of extraction should be kept clean by rinsing with warm, salty water.
