This reminds me of the last time I visited the hygienist a few months ago. She replaced a lovely lady who I used to enjoy seeing, but this new woman really does take pleasure in causing as much pain as possible.
Anyway, my two front teeth are chipped and the enamel on the back of them has worn away. She opened my mouth and said 'What have you done to your front teeth?' I told her I hadn't done anything but nothing I said made her believe me. She insisted it had been caused by some sort of trauma to the teeth and that I should have got them seen to when it happened, but I've never had any kind of accident that would cause it and my dentist has never said they're anything to worry about.
She still didn't believe me and carried on mutilating my gums.
I'm due for a clean in April, I'm hoping she'll have moved on by then, grrrr.
