I am enquiring on behalf of a colleague Trombone player for a dentist within reasonable travelling distance of Sunderland. Basically he has had all his teeth removed and is finding difficulties with his dentures as they keep working loose! He has tried several brands of fixing paste/powder but without much success. Does anyone know of an experienced dentist in this area who has the knowledge to sort the problem? Suggestions would be appreciated either in the forum or by pm if you prefer. Many thanks in anticipation.
