I have had an extraction and have a missing tooth.
My dentist can order and fiit a larger or double crown on the neigbouring tooth.
Is this a good lasting idea and could pressure on the gap tooth with no support
on its shared half be a concern?
I have heard of same day implants for around £1300.
It depends IMO a lot on what you general dental health and bone density are like. How much do you trust your dentist and what does the dentist advise? I wuld only go to my own dentist for implants (I have one and one failed, not his fault) so cannot comment on implant only services. having also had one go wrong because of a pre-existing infection which had probably been in my sinus for years, I wouldn't consider going abroad for implants.
I have recently had that kind of crown (rather bridge I think) which fills a gap by being half crowned on to the good tooth next door. I couldn't be happier with the result although it did cost over £700 (I was told only a false tooth on a plate was available NHS). That was about 6 months ago and have no problems. I happily eat toffees on it! It also greatly increased my confidence about smiling because the gap showed when I did.
I had a double crown fitted to replace one of my back teeth, it has been absolutely fine for the past 5 years and no reason to think it should not last. I am not sure how robust it would be if it was a biting tooth.
Have you discussed a bridge with your dentist.
These are questions you should be asking your dentist as only s/he will have examined you and have the clinical information needed to advise you on your treatment options.
