Will a tooth that has 75% missing above the gum be strong enough to take a crown?

Only the front side of the tooth remains - it is also the tooth around which the clasp of my metal upper plate fits. Alternatively should I have that tooth removed and fit the brace to the next good tooth? Should this tooth then be crowned to protect this tooth?

surely your dentist could answer this?
Reply:Your dentist would be the best one to answer this question.
Reply:Yes, your dentist would be the best to answer this, but from personal experience, I have one and I have a crown. Now, buyer beware--with a tooth that fragile, the crown may not last that long. After two years, I had mine replaced. Good luck.
Reply:My brother is a dentist, if you're 50 plus, no. If you're 30 do it. When you turn 59 you'll have to have it cut out. My opinion is get the tooth pulled.
Reply:Is the tooth loose? If there is enough bone to support the tooth and the partial then I surely would have a crown placed on the tooth. The more teeth you have removed, the more bone loss will occur down the road. If you decide to have the tooth pulled then you shouldn't need a crown on the tooth behind it. It is not the partial that is causing the bone loss, it is you. Bacteria or infection can cause periodontal disease. Also smoking, drinking, grinding and clenching teeth, and some medications.
Reply:There is not enough tooth structure left to be able to support a crown. It would likely just break off and may not even be able to withstand the preparation for a crown. Your best bet is to get that tooth extracted and they can get another tooth added to your partial denture.

YES that tooth will take and hold a crown. A regular crown would not be successful so you will be given something called a Post Crown. In this case as the remaining amount of tooth insufficient a post is needed to hold it. A tiny hole is bored down through the remaining tooth into the root and a tiny metal post is fixed into this, your new crown is fitted on to this. These crowns are very common. As you can imagine these crowns are not as strong as a regular crown, but generally last well enough.I have two and no problems, with these age isn't an issue. Another alternative is to have an implant,this is more expensive. I think the crown will work.How about a best answer for this??!!
Reply:Probably NOT. But check with your dentist.


Normally the decay in an upper molar leaves only the outer shell (as you describe), and the inside root has been severely weakened.


Even with a post and core as suggested above, I would be very wary of rebuilding such a tooth.


Should you then crown the next tooth in front? Perhaps - there needs to be a thorough assessment of all your remaining teeth before that could be recommended.
Reply:It should be possible to strengthen the broken tooth by building it up with special core building materials by your Dentist as long as the nerve of the tooth (if it has one) is not affected it can then be crowned and the crown will be specially made to help retain the plate.


Only your dentist can really answer your question because other factors may affect the result.


If the Dentist decides to remove the broken tooth then the missing tooth will be added to the plate and the clasp will be moved to the next good tooth, again the Dentist will decide if he feels it should be crowned. Hope this helps good luck!
Reply:I am a dental nurse so I may be able to give you some advice.


If there is no or very little decay and the root is solid they your dentist can put a post into it and mount a crown on it. It will be strong enough to support your denture although the denture might cause the porcelain to chip off the crown. You could have the root removed and have it added on to your denture. Even if the root is dead it can be root filled then crowned. Personally from what you have said it seems like it would be possible but do ask a dentist. Good luck.
