Medical Forum / General / Dentistry / May 2008Crown longevity?
I've read here and elsewhere that crowns only last 5-15 years on average. What happens after that? Do they replace the crown or does the tooth have to come out? Thanks. > I've read here and elsewhere that crowns only last 5-15 years on average. > What happens after that? Do they replace the crown or does the tooth have to > come out? Thanks. Average numbers are meaningless, because of wide variation. The tooth may fail for other reasons--say, periodontal--that have nothing to do with the crown. If a well-made crown fails because there is decay at the gumline, you could not properly consider that a failure of the crown. Likewise, the condition of the tooth at the point there is a problem will generally indicate whether it is a good idea to replace the crown, or lose the tooth.

Ok, I thought I had read that it lasted only 5-15 years due to normal wear and tear. Are you saying that a well made crown (barring periodontal issues) should last a lifetime? Are there any special steps I should take for a crowned tooth above and beyond a normal tooth? Thanks. > Ok, I thought I had read that it lasted only 5-15 years due to normal wear > and tear.

Fire, flood, terrorist activity....decay, accidents, errant olive pit--s**t happens. I have an elderly man who survived a concentration camp. He came to me with 4 large gold veneer bridges that had been placed in a Swiss army hospital when he was liberated. One had a rotted abutment, and I replaced the bridge. The rest looked like hell, but were still functional, and he didn't want them replaced. AFAIK, they're still in service over 60 years later. Most patients wouldn't tolerate the space under the pontics, the appearance etc., but for this man's purposes it was still functional, and I wasn't going to pressure him to replace the 3 remaining bridges. > Are there any special steps I should take for a crowned tooth above and > beyond a normal tooth? Avoid olive pits in olive bread, don't chew on ice cubes, pens, pencils, blasting caps... Steve > Thanks.

Strictly stick to det cord ! > But no blasting caps, right? For some odd reason, that brings to mind a fake commercial on " A Prairie Home Companion" from years ago. It was for "Blo-Gel, the plastic explosive you use at home". I believe they suggested stuck windows and home-style tooth extractions as good uses for the product.

Any chance of an audio clip of that ? >> But no blasting caps, right? > [quoted text clipped - 6 lines] > > Vaughn Ketchuuuuuuuuuuuuuuuuuuuuuup! I think the most damaging habits are night time clenching and bruxism. If there are signs of parafunctional activity, an NTI is the best insurance to prevent damage (for all of the teeth, not just crowns).

Oh yeah, I'm done with chewing anything harder than a piece of toast. But lets say a crown fails. How is it replaced? Is the remaining tooth weaker the second time around? >>> Are there any special steps I should take for a crowned tooth above and >>> beyond a normal tooth?

Laws of physics, classical mechanics, and all that... Just a primary though, 8/25-28/08 Denver should be interesting. Chinese proverb: "May you live in interesting times." Seems we are. Sun Tzu Chapter IV. TACTICAL DISPOSITIONS 2.) To secure ourselves against defeat lies in our own hands, but the opportunity of defeating the enemy is provided by the enemy himself. [That is, of course, by a mistake on the enemy's part.]
