The first thing you need to do is to pay attention to oral hygiene and health care when you have sore and tender teeth during the menstrual period. If the oral hygiene is not good, there may be persistent tooth sensitivity problems, which are generally more likely to be caused by changes in oral hormone levels. Coupled with the swollen pain in the gums, changes in hormone levels can cause oral problems. Therefore, patients should pay attention to oral health care in daily life, brush and rinse their teeth in time to avoid the effects caused by bacteria and food residue retention. In addition, after correlation treatment, some local therapeutic drugs or desensitizing drugs can be effectively applied to relieve the tooth sensitivity irritation. Patients usually should not eat foods that are too acidic, too cold or too hot to avoid the occurrence of irritation, which can cause some serious problems. Therefore, oral hygiene is very important during the menstrual period.
