Wisdom teeth are generally not recommended to grind off the corners, mainly because it may lead to dentin hypersensitivity, tooth decay, pulpitis, food impaction and other adverse consequences. 1. Dentin Allergy: Wisdom teeth may expose the dentin layer after grinding off the edges, which may lead to soreness and pain when the teeth encounter hot and cold stimuli as well as food, mechanical and other stimuli, which is also known as dentin allergy, so it is not recommended to polish the edges. 2. Tooth decay: If the wisdom teeth are not cleaned properly after polishing the edges, the risk of tooth decay will be increased, so it is recommended that the wisdom teeth be extracted as soon as possible. 3. Pulpitis: After grinding the corners of wisdom teeth, if the grinding amount is too much, it may cause the pulp to be exposed and infected, resulting in pulpitis, leading to severe pain and other problems, so it is recommended to go to the hospital for oral radiography and then timely removal of wisdom teeth. 4. Food impaction: clinically, when wisdom teeth erupt orthodontically and have a good occlusal relationship with the opposite jaw wisdom teeth, no special treatment is needed, but if there is an obstruction of wisdom teeth, simply grinding the corners may lead to food impaction, which affects oral hygiene.
