Can you get a filling or root canal treatment during your menstrual period?

Generally, whether dental fillings or root canal treatment can be performed during menstruation depends on the type of procedure. Simple fillings are usually acceptable, while complex root canal treatments are best avoided during this period. The detailed analysis is as follows:

If the filling is simple, such as for shallow or moderate cavities, which only requires removal of decayed tissue followed by filling, the procedure is short and minimally invasive. It typically has no significant impact during menstruation. Since this treatment mainly involves hard dental tissues, it is less affected by hormonal changes related to blood clotting and pain sensitivity. As long as the patient does not experience notable discomfort, the procedure can proceed normally.

However, for complex root canal treatments—such as those involving multi-rooted teeth or cases accompanied by periapical abscesses—it is advisable to avoid treatment during menstruation. Hormonal fluctuations during this period may slightly impair blood clotting function, increasing the risk of bleeding during the procedure. Additionally, heightened pain sensitivity could worsen discomfort and potentially affect postoperative recovery.

Extra attention should be paid to oral hygiene during menstruation. Maintain regular brushing in the morning and evening, use dental floss, rinse after meals, and reduce intake of sugary foods to prevent worsening dental issues. If tooth pain is severe, cold compresses may provide temporary relief; however, proper dental treatment should be postponed until after menstruation ends.
