You should discuss the specifics of the financial arrangement of your situation with the dentist. Normally there is no guarantee or warranty implied with dental work but of course, your good will and trust is important to his practice and I'm glad that you are giving him the opportunity to correct the problem. If he's having problems, you may want to ask him to refer you to a specialist or someone else who can handle the problem and correct the situation instead of suing him.
I'm not so sure about the pin exactly. My interpretation of a pin is a small pin used to hold the "core or buildup" in place. I think you may be speaking about a post (larger) which is placed down the root canal to help provide retention (something for the bridge to grab onto). If the post is broken and can't be removed, extraction is probably the most likely scenario at this point. A broken post may indicate also a broken root which would be a source of infection.
Implants may be an alternative but you would need to discuss that with your dentist or another dentist.
Hi May!
Really upsetting story.. just for you to know, it is not normal. Normally, in such cases, one shall have a guarantee on that dental work... Yes, if it is always falling down, it i awful and also not good, if someone has to do it with a loctite, there are special glues for that.. You possibly have an invoice and - hopefully - a guarantee from him. Would nothing happen and he would not change his the bridge or even not do anything, you still can sue him. My aunt was not satysfied with the dentists in the UK, so she went to Hungary, to the empireclinic and got a really good treatment.. with guarantee!! I am happy to say that she probably won't need that, me i am the next to go in June.. check the site, they also can tell you things without your personal visit there, send them the x-ray of your husband, they will probably have a competent opinion you can rely on.. doesn't cost nothing to ask them.. so, success!
