Menstruation does not interfere with dental fillings and will not cause any adverse effects. Dental filling is a common dental treatment and a routine procedure that can be performed during lactation, menstruation, or pregnancy. Therefore, there is no need for excessive concern. It primarily involves the use of resin or glass ionomer materials for restoration, which can improve tooth damage, enhance chewing ability, and maintain a relatively long duration. After the filling, the material does not immediately solidify, so it is best to avoid chewing too hard or sticky foods in the short term, as this may cause the filling material to fall out and affect the restoration effect. In daily life, attention should also be paid to oral hygiene care, and a good habit of brushing teeth every day should be developed, such as brushing in the morning and evening or rinsing after meals, ensuring that the tooth surface and gaps are thoroughly cleaned. During menstruation, special attention should be paid to diet adjustment, and food that nourishes qi and blood should be consumed as much as possible.
