Hi,
this might be a longer post so beware. But basically I am going through a lot of anxiety around teeth and all things related and don't know what to do with it.

I've never been scared of the dentist, you could even say I would be one of these children that looked forward to the routine dentist checkup, since they would always be painfree last about two minutes and in the end I would be given a cute new toothbrush with a picture of a fairy princess.
 This all changed late last year when my mum lost several teeth due to untreated periodontal disease (bad dentist, probably some bad dental care habits and some genetics /mum always had problematic mouth since she was a kid/) and several months later I changed my dentist and all of a sudden went from "near perfect teeth" to several cavities and 1 mm of bone loss (at 23 years old). 
 Since then I've been going crazy just thinking about teeth. I've cried in the dental office nearly every time I went there (for the cavity filling) and had several panic attacks thinking all of my teeth are gonna fall out. Being this very obsessed with my teeth made me 1) finally step up my dental care game (yay to flossing and brushing two times a day!) but also 2) obsessively check if my teeth are ok and securely in place. I would repeatedly wiggle my teeth, sometimes until the point I would start to feel them give in and get the tiniest bit loose. At which point I would inevitably spiral deep down into anxiety hole. Sometimes I also clench my jaw or just go over my teeth with my tongue multiple times.

I had some anxiety issues before, but this whole teeth thing brought me to a new level of anxiety hell.

Do you have some suggestions on how to deal with this? Should I tell my dentist? Self-help remedies? Any idea will be well appreciated.
