I have veeners which are years old and I feel that they are too heavy. There are 6 in total can they be replaced and how much would this cost, my hygeine is not good because the veeners are so close together can they be taken off then hygeine work done for a bit before others put back on? (mouth is in a bad way) I would be grateful for advice here I hate my teeth can you give me some advice because there are so many denists out there
