MOH has broken a few of his bottom teeth with constant grinding, more seem to be breaking by the day. His dentist wants to do root canal treatment, even though he is 80 this year. Since seeing the dentist Monday last, we have two more broken teeth. He has had two guards made, both of which he has accidentally thrown away, at £80 a go from the dentist, it just can't be done, however the dentist wants to make another one ! We are spending so much money at the dentist, it's unreal. He has blackened teeth, we think from using tea and coffee as a mouth wash, and several are missing, the plate he had made no longer fits, so more expense. We have asked about removal of all his teeth, as there doesn't seem to be a satisfactory solution to the problem, but the dentist doesn't want to do that. What would you do ?
