Q. I wanted to change my metal fillings for white ones.I paid £150 to have one done and the experience was awful.THe dentist made me feel like a naughty school child making remarks such as”You can make this longer if you like”I was told my the receptionist that as he started my treatment then he would have to continue.The new filling I had was so uncomfortable and extremelely painful when I chewed but again I was told only “my dentist”could rectifty the problem.Reluctantly I have gone back to the same man to have another filling replaced but as I have been grinding down on a bottom tooth he now says I have to have a crown costing £490I please advise.thanks,
