Q. I had root canal on my 2nd premolar on the right hand side of my mouth (5th tooth over)10 years ago. I havent had any touble with it since but about 18months ago I went to a new dentist who discovered it was infected and had to be dug out and repacked with anesthetic. I have now managed to break the front of the tooth off. I went to my dentist and she said it was infected again so there was little point in getting a crown and she has recommended i visit a dental surgeon to have it extracted (the root is pointed apparently). My options then are to have a bridge crown (£600) or screw in tooth (£1500). It is not causing me any problems and i cant really afford to replace it at the minute. I have also heard that if its removed and I choose not to replace it there is a chance my other teeth will move into the space etc. Its far enough back in my mouth and cant be seen so Im just wondering is there any reason why i cant leave it as it is for a while until I can afford to have it replaced? or should i go ahead and have it removed now and replaced or can i safely leave the gap?
