It is important to find out the cause of frequent tongue ulcers and treat them for the cause. The common reason for frequent tongue ulcers is low immunity, or nutritional imbalance, lack of vitamins or trace elements in the body, etc. Ulcers are prone to recurrence, and the attack will be red, swollen and painful, and sometimes the pain is unbearable and affects normal eating and work life. You can have the appropriate examination, vitamin supplementation, intramuscular injection of transfer factor, strengthen physical exercise, eat more vegetables and fruits, pay attention to nutritional balance, and improve the immunity of the body. The affected area can be cauterized under surface anesthesia to promote the healing of the mucosa, and then iodine glycerin can be applied to relieve the painful symptoms. Frequent tongue ulcers may also be related to the presence of stumpy crowns and roots or poor restorations inside the mouth. Tongue ulcers often coincide with irritating factors. Teeth that have no retention value should be extracted as early as possible, sharp tips should be ground down as much as possible, and bad restorations should be removed as early as possible and then redesigned and restored to avoid long-term repeated irritation causing ulcers to become cancerous. Frequent tongue ulcers can be supplemented with vitamins, or transfer factors can be used to improve immunity, and local mucosal lesions can be cauterized to promote healing and relieve pain.
