Hi, had one about 20 years ago and have been told it needs redoing. I had awful pain over Easter even though the actual tooth is crowned. Dentist took an xray and said the was infection around the tip of the root. Gave me antibiotics which stopped the pain but now I have a large hard lump on the gum. Dentist can`t do it so been referred to a local hospital, they have now written and said the work will have to be done by a consultant. Feel abit worried as its not a pleasant procedure. Feel a wimp saying that when my dh has been through hell with cancer treatment the last five years.
