Q. Hi i am having a problem with my dentist matching up my bridge shape and colour the last time it was cemented perm in my mouth making this a very painful situation the next time will be the 3rd time. I dont mind the returns to obtain the best results how ever i am concirned after my last visit i ended up with an ulcerated gum around the bridge, I had all my top crowns replaced tooth whitening on my lower teeth and have spent quite a lot of money already at the dentist. And on a previous visit after five hours between the dentist and hygenist became very ill and needed the paramedics out. I am getting reluctant about these visits.
