Are there dental impacts of hormone therapy ?

I had ac and taxol chemo in 2016 and now on Letrozole, and I wish I had been told to have a dental check up before starting all this. I felt like my teeth became very delicate during chemo, and during and after chemo 2 of them broke, and I feel they are not as strong as they once were. Have just been to the dentist this week to have a filling replaced, and was told I will need 2 of them capped some time within the next year. I think it should be standard advice to have a dental check and clean before starting cancer treatment.
