No tooth loss but my gums bleed easy

I take 3 different types of medicines and I have lost some teeth

My son has smashed his teeth so many times from seizure

The medication can give you a dry mouth and whatever sugar you have triples huge hugs x

I don't have any bleeding or tooth loss either but for years I had trouble with my teeth because of medicine. I have braces to correct them, sometimes I'm afraid when I remove the braces the teeth will shift back. My gums don't bleed, they swell.
