발치, or tooth extraction, is a dental procedure where a tooth is removed from its socket in the jawbone. This procedure is often necessary due to various reasons, such as severe tooth decay, gum disease, or overcrowding of teeth. Dentists typically perform this procedure under local anesthesia to minimize discomfort. After the extraction, patients may experience some swelling and pain, which can be managed with prescribed medications. Proper aftercare, including avoiding certain foods and maintaining oral hygiene, is essential for a smooth recovery. Regular check-ups with a dentist can help prevent the need for future extractions.
