Hi Kman,
I have a real issue with brushing my teeth too. Just after I got married, a dentist told me that the enamel on a lot of my teeth had been damaged by orange juice. My former dentist had never mentioned anything about that

Soon afterwards, I needed veneers on my four front top teeth. The veneers have worked very well, and overall my teeth are ok in most ways. I haven't had a filling since I was about 15.
But I am still "paranoid" about my teeth. For several years, I spent far too long brushing my teeth, and I hated eating sugary things without eating cheese afterwards (which is supposed to help prevent decay)
But lately I have gone the other way, and I go for a few days sometimes without brushing them at all

I still can't seem to spend a "normal" time brushing them. ie. the recommended 3 minutes ... it takes me far longer, and I often end up not doing them at all
So I can certainly relate to issues with tooth brushing
Take care,
Fuzzy
