Dental cavity crown-re;ated?

Indirectly, maybe: Question is too vague, but i'll address possibilities. If a crown is poorly designed with a gap in the fit on the tooth, a cavity could develop in gap. If cavity remains after tooth reduction for crown, it may continue to progress under crown. If a crown doesn't contact adjacent tooth well, food trap forms which creates a condition for a cavity to occur on adjacent tooth or at margin of crown. ...Read more

Pain in gums where crown is placed? Is that cavity or gingivitis?

Pain in gums where crown is placed? Is that cavity or gingivitis?

It is possible: A little more history about the onset and type of pain you are experiencing is necessary. If the crown has been in place for a long period of time, you could have recurrent decay in the tooth. You could also have a periodontal or gum problem. If the crown is a new crown, it could be related to irritation from the seating of the crown, possibly some residual cement, or your occlusion or bite. ...Read more

I have to replace a crown and get a filling for a cavity. Which one should I get done first?

I have to replace a crown and get a filling for a cavity. Which one should I get done first?

Both: The extent of the problem in each will determine which one is more important to do. Your own dentist can answer that question better than we can never having seen either tooth nor x-rays of them.

What are the pros and cons to electively (no margin cavities) remove old porcelin fused to metal teeth crowns for new ones? Could a tooths root split?

What are the pros and cons to electively (no margin cavities) remove old porcelin fused to metal teeth crowns for new ones? Could a tooths root split?

Not likely: Of course, it's always a possibility, but root splitting is not likely, as long as when the crowns are being cut off, they are fully cut through, down to the tooth, before they are removed. Really, unless you have decay on the teeth, there is no need to remove the old crowns. Unless you don't like the look of them or the porcelain has chipped off. ...Read more

I have two cavity holes in my front teeth, roughly how much would it cost to crown them? And what is the best natural crown type

I have two cavity holes in my front teeth, roughly how much would it cost to crown them? And what is the best natural crown type

Cavities: Without knowing the exact extent of the decay, it is hard to determine what treatment you need and what the total cost would be. Simple fillings are less expensive that root canals, posts, and crowns. That being said, since fees vary so widely from town to town and office to office, a fee quoted you over the internet is meaningless. Seek the advice of a local dentist who is going to treat you. ...Read more

13 year old has deep cavity... Dentist says she needs a root canal. Is that safe? She'd have to get a silver crown. Is it better to just pull it?

13 year old has deep cavity... Dentist says she needs a root canal. Is that safe? She'd have to get a silver crown. Is it better to just pull it?

No-no -no: If your finger was broken would you want it amputated? A root canal would preserve the tooth and keep all the other teeth in line and prevent crooked and shifting of other teeth. A missing tooth can cost more to replace than a root canal and crown. ...Read more
