Hi Bryanna -
a somewhat belated update to the issues I had with my bridge - I thought you'd like further confirmation of how valuable your advice is.
After your advice on the forum, I consulted another dentist who referred me to one of the top endodontists in the UK based in Harley St, London - he confirmed your opinion entirely! ie, that the whole bridge should be removed etc, and the causes of the infection etc dealt with before moving on to eg any new crown/implants etc and (as you also advised) not to proceed with the procedure recommended by my (previous)dentist.
So many thanks again, and although it is a rather crude measure of the worth of your advice, you might like to know that the Harley St endodontist charges around $500/hour just for a consultation!
