Tooth extractions are dental procedures where a tooth is removed from its socket in the jawbone. This is often necessary due to severe decay, infection, or overcrowding. Dentists or oral surgeons perform the procedure, ensuring the patient is comfortable, often using local anesthesia to numb the area. After the extraction, patients may experience some swelling and discomfort, which can be managed with pain relievers. It's important to follow post-operative care instructions to promote healing and prevent complications, such as dry socket. Regular dental check-ups can help avoid the need for extractions in the future.
