Osmosis video - Periapical lesions

Periapical lesions are abnormal growths or infections that can occur around the root tip of a tooth. Periodontitis and periapical abscess are among periapical infections. Periapical lesions can be caused by tooth decay, trauma to the tooth, or a previous dental procedure. Symptoms of periapical lesions may include tooth pain, swelling in the gums, and sensitivity to hot or cold temperatures. Treatment involves antibiotics, pus drainage if any abscess, endodontic treatment of the tooth, and if all fail, extraction of the affected tooth might be needed.
