I have a decayed tooth. How much tooth structure is needed for a crown only and how much warrants a post and core?

Broken down tooth: There are no absolute values do determine if a crown or filling is needed. If the decay is very deep, then root canal therapy is needed in order to place the post. If you are unsure of the diagnosis, get a second opinion.

How is crowning done on a tooth?

How is crowning done on a tooth?

See below: A compromised tooth (fracture, failing old filling) may need to be covered and protected by a crown. First, there must be enuf healthy tooth as a foundation. It may be necessary to do a "core buildup". Then the tooth is reduced in all dimensions (ground down if you must), a mold (impression) is taken, and then a crown is custom fabricated to recreate the tooth that was once there.

What is the solution for composite restoration overhanged proximally in rct tooth? Do I have to remove old one and replace it or crowning the tooth?

Depends: It really depends on the condition of the tooth, is it otherwise healthy with intact walls? If so then have the filling replaced so you floss there without a problem. If the tooth is heavenly restored with large or multiple filling then crowning the tooth would be best.

How far is it possible for you drill a tooth down without crowning it?

How far is it possible for you drill a tooth down without crowning it?

Why Is it Drilled: It depends why the tooth is being drilled. If the bite is off, an adjustment of the tooth usually takes off a small fraction of a millimeter of the enamel outer coating. Small areas of decay can be drilled out & a simple filling placed. When decay is deep, the tooth is fracture or more and 1/2 to 2/3 of the tooth needs restoring then a crown is needed.

Loose tooth post-root canal & crowning, how can this be remedied?

Loose tooth post-root canal & crowning, how can this be remedied?

Loose from?: If the crown is loose, intact and no caries, the crown might be able to be re-cemented. If the structure inside the crown is decayed or fractured, at least a new post and crown. If the tooth is unrestorable due to root fracture, periodontal breakdown, untreatable infection, etc. An extraction would be in order. This needs to be evaluated in person by a dentist who can discuss your options.

Why do teeth need crowning?

Why do teeth need crowning?

Strength mostly: Most of the time a tooth will need a crown to add strength to the existing structure. If a tooth is broken down, has decay, is too weak for a filling, then the crown would be made. Crowns can be made to increase function if teeth are not the proper size and shape. Crowns can also be done for cosmetic reasons if the patient does not like the look of their own tooth.

How can you repair teeth crowning?

How can you repair teeth crowning?

Depends: Do you mean repairing a tooth with a crown or repairing a tooth with a crown already on the tooth? Repairing a tooth with a crown on is often possibly by putting a small filling at the edge of the crown where there is decay. If you mean repairing a tooth by placing a crown, then it is an entirely different procedure. After preparing the tooth, a dental lab makes the crown & the dentist cements it.

Does teeth crowning require anesthesia?

Just local: No need for anything more. I find that giving only what is needed and thereby decreasing risk by not adding more drugs is the safest way to practice.

Could my dentist put me to sleep for having crownings on both front top and bottom teeth?

Sleep dentistry: Yes, however he needs to be licensed to be able to use sedation in the office. It does add significantly to the cost of the care.

Itero would certainly seem so much more accurate at the tooth root margin than the traditional approach manner of making a crown. Ledge emphasis.?

Itero would certainly seem so much more accurate at the tooth root margin than the traditional approach manner of making a crown. Ledge emphasis.?

It's the dentist: It's the quality of the dentist and his care and expertise, not the type of specific crown material or brand name used that is the important criteria. I would rather have michelangelo paint me a picture with finger paints than my daughter using the finest artist materials available.

How can a crown on the tooth work?

How can a crown on the tooth work?

Crown: A crown is cemented on your tooth so it will not come off. It will protect the tooth and provides the strength needed for eating, speaking and other normal functions. You take care of a crown just like any other regular tooth with good brushing and flossing and it should last many years. I hope this answers your concerns.

What is life like with a tooth crown?

What is life like with a tooth crown?

Crowns: When done correctly it should feel pretty much like a regular tooth. Initially it may have a different feel to your tongue or to bite but will become normal fairly soon. Make sure you need a crown though. A lot of times they are over kill, when a more conservative restoration can be done, like an onlay. Many times aggressive crowns can lead to root canals.

Do you get a shot when making a tooth crown?

Do you get a shot when making a tooth crown?

Depends: All depends on whether the tooth is vital, or has had a root canal. If vital, I would recommend local anesthesia. In 35 years, I have only done a few crowns on vital teeth without local anesthesia (at patient's request). If root canaled tooth, no need for local anesthesia, unless the tissue is sensitive, then only a little is needed. Discuss with your Dentist. Good Luck.
