You wouldn't trust a dentist because of that? I wish I could say the same and for that reason.
I've had a phobia for years about going to the dentist and couldn't cope with my last toothache. Decided to visit a Polish dentist charing 80 Euro for an extraction but she ended up ripping off half my molar along with my gum and refused to continue cause she is was too afraid. Its now costing me a good chunk of money to have it fixed by a specialist and I'm looking at 6+ months recovery time for the gum.
Cormac, good luck at the dentist.
