Generally speaking, root exposure does not recover by itself. Root exposure is usually caused by loose teeth due to periodontal disease, or the formation of calculus due to long-term food impaction or incorrect brushing methods, etc. Usually, it cannot recover by itself and requires symptomatic treatment according to the condition. If the root is exposed due to long-term attachment of tartar resulting in lowered alveolar bone height, bad breath, yellow or black, hard plaque at the junction of the tooth and gum, etc. may occur, and periodontal surgery and bone grafting surgery are required for treatment, but complete recovery is more difficult. If it is caused by chronic inflammation in the apical area, there are usually symptoms such as chewing discomfort and weakness of bite. You can first treat the root canal and then remove the exposed roots, and when the alveolar bone heals, the roots can be rewrapped. Tooth root exposure is recommended to go to dentistry for dental film and other examinations for effective treatment. In daily life, you should brush your teeth in the morning and evening, rinse your mouth after meals, keep the inside of your mouth clean, and clean your teeth regularly.
