Tooth extraction is a dental procedure where a tooth is removed from its socket in the jawbone. This may be necessary due to various reasons, such as severe decay, infection, or overcrowding. Dentists or oral surgeons typically perform the procedure under local anesthesia to minimize discomfort. After the extraction, patients may experience some swelling and pain, which can be managed with prescribed medications. It's important to follow post-operative care instructions, such as avoiding certain foods and maintaining oral hygiene, to ensure proper healing and prevent complications like dry socket.
