The Ketzos Hashulchan 126:3 discusses issues with teeth becoming a concern of protecting one's health. Do Poskim today suggest the frequency one must visit the dentist to preemptively protect one's health or is it only an obligation to go when there is currently an issue?
I've heard the authorities of today (e.g. Rabbi A. Weiss) teach that the Torah expects one to following medical recommendations. Have you consulted your dentalcare professionals regarding this issue?
