protective coating

I've heard there's a permanent coating that dentist can apply to teeth that helps prevent cavities.My dentist tells me it wouldn't do any good at my age,54.Does anyone know if this is true?

yes, the only thing i can think of is selants.

and no, it would not work, that only works when you are younger, when your perment teeth are first coming in and there are NO cavities, "soft spots" if there is a slight cavity you cannot put them on.
so the older you are the more likely that of a start of a cavity that is undetected.

Thanx for your response.Looks like i'll do it the old fashion way,with the toothbrush & regular check-ups.

Even IF you were to get the sealants, that in itself is no replacement for good dental hygeine and regular check-ups.
