Hi Stuart, do you mind me asking where you got the treatment done in UK. A private dentist did mine and i have to do them again, i have found out that the filling material could be unsafe, especially in the future, i need to start work next year so i need to be healthy and not worry about it. I hope you didn't get them done by NHS, cos they havn't got a clue, i swear they are trying to kill us! Good luck!
