Extraction is a procedure where a badly decayed or broken down tooth is removed from the oral cavity. In cases of erupted wisdom tooth, it is sometimes extracted because it is a source of food trap and to prevent further damage to the neighbouring teeth.
To prevent unnecessary extraction, it is advisable for patient to see the dentist regularly so that any initial caries or problems could be addressed before it worsens. Patients are advised to keep a good oral hygiene by brushing and flossing their teeth regularly.
