How do I know if I need a crown on one of my molars?

Alternative: Your dentist can give you an opinion. With the development of strong porcelains, crowns can almost always be avoided today. Ask about porcelain onlays as an alternative to crowns. Not only are they more attractive, they also leave more of you own tooth. They can be made chairside in a single visit with the use of a computerized process called cerec. ...Read more

Is there any assumed guarantee on dental crowns? A few years ago, my former dentist put a crown on one of my molars. Recently, a part of the crown (near the gum line, between teeth) broke off, and food is getting trapped in the resulting gap, causing gum

There : There are no guarantees expressed or implied with any medical procedure, and it is unethical for any health care provider to do so. You do not say how old the crown is, but it is possible that something is breaking down under the crown. It could also be that nothing broke off, but in fact, you have a bone loss in that area resulting in a space and a bacterial/food trap. Was a recent radiograph taken? What did your current dentist tell you? This cannot be left untreated. From your description, and assuming you are correct that something did break off, it could be that a small piece of porcelain chipped off the crown. If the gold coping under the porcelain flexed due to a cavity in that spot, the porcelain could flake off. If there is a cavity, it needs to be taken care of. Even if no cavity, the food and bacteria being trapped will constantly keep the gum tissue in that area inflammed, which can lead to a periodontal defect. You should see your new dentist to determine what exactly the problem is and what would be the proper course of action. ...Read more

A piece of one of my molars has broken off after accidentally biting a hard peppercorn. It hurt at the time but feels fine now, what should I do?

A piece of one of my molars has broken off after accidentally biting a hard peppercorn. It hurt at the time but feels fine now, what should I do?

Exam: The usual situation is that you have an area of decay in the tooth that eroded the supporting dentin under the surface enamel. Once sufficient pressure was applied to the unsupported enamel, it snapped off. If you wait long enough, the only option will eventually become extraction. Get it looked at by a dentist to assess your options asap. ...Read more

What are the odds of an oral cyst returning after removal? I had an oral cyst near one of my molars removed, and was wondering if it's likely to return? .

What are the odds of an oral cyst returning after removal? I had an oral cyst near one of my molars removed, and was wondering if it's likely to return?


.

The : The chance of recurrence of any oral lesion depends upon the nature of the lesion and how completely it was removed. When a lesion is removed the tissue is typically sent to an oral pathologist for evaluation. A report is sent to the surgeon indicating the nature of the lesion and if it has been completely excised. As to see the report and have it explained in terms of potential recurrence. Keep a copy for your personal records in case you ever change dentists or move. ...Read more

I have a gum pocket on the outside of one of my molars. A wisdom tooth is starting to surface behind it. Could the wisdom tooth be causing the pocket?

I have a gum pocket on the outside of one of my molars. A wisdom tooth is starting to surface behind it. Could the wisdom tooth be causing the pocket?

Yes: You are correct, as a wisdom tooth erupts into the mouth, it can create a pocket in the gum, especially if the wisdom tooth is erupting abnormally. This pocketing may or may not be a problem that should be examined by a professional. It could be at risk for food impaction and subsequent infection. Have a professional provide a oral exam and explain your options and any risks. Good luck :) ...Read more

It is possible: Dental sealants help reduce the risk of developing cavities on the biting surfaces of teeth. They can’t prevent 100% of cavities from forming. Whenever you have tooth structure, you have the chance of developing decay. ...Read more

Once you have cracked tooth syndrome, are you going to inevitably get more cracks? I've been told I have cracked tooth syndrome and several small cracks in one of my molars. I'm not sure what causes it, but i'm worried that once it's started i will just w

Once you have cracked tooth syndrome, are you going to inevitably get more cracks? I've been told I have cracked tooth syndrome and several small cracks in one of my molars. I'm not sure what causes it, but i'm worried that once it's started i will just w

Cracked : Cracked tooth syndrome (cts) involves a crack in the tooth portion that is above the gum line. 90 % of cts is fixed with a simple crown. It keeps the cracked part of the tooth above the gum line from moving & all the symptoms from being stimulating. The other 10% need root canal as well because the crack has reached the root canal system. If the crack is one of the above (described as favorable) this is a complete cure. If the tooth is cracked further below the gum, involving a fracture (or crack) of the root, the tooth will need to be extracted. Your dentist will know because there will be a space in the attachment of the tooth to the bone, just in the location of the crack. Xray evidences this type of crack, whereas cts is not discernable on xray exam. ...Read more

Is cracked tooth syndrome the same thing as a fractured tooth? Part of one of my molars cracked off while eating last night, and i'm trying to do research to figure out what happened. Are they the same thing? .

Is cracked tooth syndrome the same thing as a fractured tooth? Part of one of my molars cracked off while eating last night, and i'm trying to do research to figure out what happened. Are they the same thing?


.

Not really: "cracked tooth syndrome" is what we use to describe a tooth that usually acts normal but if you bite a certain way you get a shooting pain. A crown is the treatment of choice. The crack is not usually detectable. A cracked tooth is when a tooth fractures. This is usually caused by underlying decay that weakens the tooth or by a very large filling. This almost always shows up on an x-ray or exam. ...Read more
