dental work

What is the name of your state? What is the name of your state? New York
Am I liable for dental work that was not successfully done? A dentist twice Tried to put on a crown, both times it came off within a week. The dentist is now charging me $2000.
In more detail
The dentist first used an epoxy post to add a crown to the stub of a tooth. This crown lasted about a week before the post broke. I then returned to the same dentist who made another attempt to add a crown, to the same tooth, but this time with a titanium post. This crown lasted less than 2 weeks. When I went back I was told that the base of the post is still in the tooth but had no additional work done. After that I went to another dentist who said 2 things
1 I was advised not have a crown on that tooth
2 Crown lengthening by a periodontist would be needed before if a crown was to be added. This 2nd dentist said that I did not have enough tooth left to support a crown unless its base was lengthend.
The dentist who failed in adding the crown is billing me for $2000.
Am I obligated to pay for work that did not succeede? If this person keeps bothering me could I file a malpractice suit?

I do not know if the original tooth could successfully support a crown but you were using it to crack nuts and broke it. The x-rays would show that.
You may have been told the crown was "iffy" and chose to proceed. Your records would indicate that.
In any event, it appears the dentist tried but your rotten tooth just could not stand up. It is not mal-practice and you are liable for the bill. If you do not pay he will put it in collections.
He did the work with your consent and the possiblity of failure is on the release. Look at the contract.
