Fillings are not recommended during menstruation, as they can cause some damage and bleeding. The poor blood clotting ability during menstruation may result in prolonged bleeding, which is detrimental to wound healing. Anesthesia may be injected during the filling, which may affect the menstruation, so it is better to wait until the menstruation is completely cleared. During menstruation, the body’s resistance decreases, which can easily cause germs and infections. It is necessary to maintain oral hygiene during menstruation by brushing your teeth every morning and evening, and using salt water to rinse your mouth after meals can reduce food residues and help your dental health. If you have dental disease, you need to treat it only after your period. During menstruation, you should also pay attention to your diet and eat more fresh vegetables, soy products, dairy products to supplement nutrition, and eat less spicy, stimulating, cold food or it will affect the amount of menstruation, and in severe cases, dysmenorrhea. Pay attention to rest and avoid strenuous exercise, and pay attention to hygiene to avoid gynecological diseases.
