Loose teeth are those that can be pushed in the alveolar bone and some cases do not require treatment. For some complex cases, such as periodontal infection and excessive tooth destruction, extraction treatment is required. The presence of approximately 0.25 mm of tooth looseness is usually considered healthy in all individuals. This looseness is known as physiological mobility. The main reason for this is that the tooth is not fused directly to the alveolar bone, but is attached to the socket by the periodontal ligament. This slight mobility is the result of applying chewing forces to the teeth while chewing without causing damage to the teeth and is something that does not require special treatment. Loose teeth are most often seen in periodontal infections, and treatment in this case is still focused on treating periodontal infections, which can effectively restore normal teeth to a fixed or slightly mobile state after the infection is controlled. For the treatment of periodontal infection, scaling and periodontal scaling are preferred in dentistry to thoroughly remove calculus and plaque. In addition, it is important to pay attention to dental hygiene in life. The momentary cleaning during scaling is difficult to control the inflammation of periodontal tissues. If the tooth is slightly loose due to injury, you should go to the dentistry department to take pictures in time to prevent any undetected root fracture, and the loose tooth can be fixed by the dentist according to the situation when the loose tooth is obvious. Gum damage heals quickly, but it often takes about 4-6 weeks for the tooth to stabilize, during which time chewing or biting should be avoided, soft food should be adhered to during the injury, and the tooth should not be pushed with the hand. Whether or not a loose tooth requires medical intervention, it is important to have the help of a doctor to determine the degree of looseness and the cause of the occurrence of the tooth for targeted treatment.
