Advice on Dental Crown
Discussion
I had a molar crowned back in October.
It came out whilst eating in late April.
Dentist fixed it a couple of weeks ago and it fell out again the next day - once again when I was eating.
So going back today to get it refitted again. So, I was wondering....
What's the expected lifespan of a crowned molar?
Is it normal for it to fall out so frequently?
What are the reasons for a crown to fall out - is it potentially a badly fitted / made crown?
Given this was done privately and was fairly costly what do I do if it falls out again - would I be within my rights to ask for it to be remade / refitted?
Thanks....

Guess it varies system to system
Ive got 3 crowns, all done through the 1 day Cerec system, my dentist felt sorry for me as another dentist butured my teeth to fit a bridge (long story) so did the first two for cost price privately 10 years ago and haven't had a single issue since.
Had another Cerec one done in one sitting a year ago, no issues at all and fixed the pain from a fractured tooth brilliantly
Sorry that the above doesn't really help you OP, but just highlighting they have lasted a long time for me!

Thanks for replies...not sure what cement was used to bond it the last time...smelled of superglue and needed curing is all I can say.
Anyhow my crown is off to be sandblasted as it's got too much cement residue left on it. So will be refitted next week.
Dentist did say that he'd sized it so the procedure would be as stress free as possible ( I'm a very nervous patient due to dentist butchery in the 70s / 80s ) so he feels the design maybe wrong and might have to be redone, now all of this is double dutch to me as far as I'm concerned the tooth has been drilled back significantly and the crown fixed on top....how much more obtrusive could this have been?

Crowns typically last about 10yrs. They then start leaking and may fall off or allow decay to resume underneath, which causes pain. If you have one falling off repeated ly it's faulty or badly fitted.
I've had one for 15+ years, it failed 6 yrs ago or so and was replaced after lengthy root canal treatment to fix the underlying decay. Fine since.

My one and only crown detached twice in four years. At the end of its life it had leaked and the foundation (1st premolar) was decaying. Infection made me do a hamster impression for a while but the tooth had to go. It was a bit tricky to extract a headless tooth - levering was involved.

Not sure what you mean by obtrusive but he sounds like he's a good bloke and will take care of you.Anyhow my crown is off to be sandblasted as it's got too much cement residue left on it. So will be refitted next week.

Ah ok, I understand now!
It's not a question of being invasive on the tooth.
Doing a crown prep is a very detailed task demanding a lot of delicate gestures to make sure the shape of the preparation is just so. you have to prepare the tooth in a slightly conical fashion with creating any undercuts which would prevent the crown from seating properly.
At the same time it mustn't be too conical or you'll have problems with retention etc.
It's complicated enough as it is (we're talking tiny fractions of a millimetre of tooth being removed at each passage) with a patient who is at ease but if you have someone who is very nervous, with a tongue wriggling around (worse in nervous patients) and them having to stop and swallow every few seconds it becomes extremely complicated. That's not considering the pressure of having several patients/emergencies sitting the waiting room...
And you mentioned that you're a nervous patient....
The upshot is, maybe, to make things go quicker for you in a reasonable time sometimes it's best to assure that you've removed all the undercuts to make sure the crown seats and that it was just impossible, without spending an unrealistic time on the job , to prepare the tooth in a detailed enough way to get good retention.
It may be that he's thinking of preparing the tooth less conically which will make the tooth more retentive for the crown.
All supposition of course
