What is Dental Crown ?

A crown is a type of dental restoration which completely caps or encircles a tooth or dental implant. Crowns are often needed when a large cavity threatens the ongoing health of a tooth. They are typically bonded to the tooth using a dental cement. Crowns can be made from many materials, which are usually fabricated using indirect methods. Crowns are often used to improve the strength or appearance of teeth. While inarguably beneficial to dental health, the procedure and materials can be relatively expensive.

A dental crown is usually a tooth-shaped “cap” that is positioned over a tooth — to cover the tooth to restore its shape and size, strength, and improve its appearance.

The crowns, when cemented into place, fully encase the full visible portion of any tooth that lies on and above the chewing gum line.

Various other relevant terms

Crown prep:

This is the design with the tooth after it has been shaved down to allow room for any crown. The preparation design is determined by the material that the crown will be made from, previous fillings, cracks, and root canal therapy performed on the tooth while trying to keep enough tooth structure for that crown to adhere on.

Margin:

This is the edge with the crown that meets the prepared surface with the tooth. This needs for being smooth with no interruptions or ledges.

Cusps:

They’re the raised or pointy parts of a crown that include the primary tools for getting and chewing food. Every time a cusp has been damaged at a cavity or fracture, the tooth needs a crown to prevent more damage.

Partial crown/onlay:

That is a crown that only covers many of the cusps of the enamel, but not all advisors. This restoration is chosen like a conservative measure to preserve the maximum amount of tooth structure as achievable. When conditions allow, this is the preferred type of overhead restoration.

Dental veneer:

Porcelain veneers are partial crowns that cover only the front and biting edge regarding teeth. These all-ceramic restorations tend to be placed on front teeth to change the color or model of teeth or add symmetry and balance to a smile. Since they are occasionally placed on crooked the teeth, treatment with veneers has sometimes been called “instant orthodontics. ”

Temporary/provisional:

That is a temporary crown that is positioned on the tooth while looking forward to the final crown for being made by the dentistry lab. Temporary crowns shouldn’t be left over a tooth for very long as they are made of weak resources and cemented with weak cement that does not seal the tooth for extended. Occasionally, a temporary crown will certainly purposely be left with for a prolonged time frame by the dentist to be sure it becomes free regarding pain or other signs and symptoms.

Why you should crown your Teeth

A dental crown could possibly be needed in the next situations:

• To protect any weak tooth (for instance, from decay) from breaking in order to hold together parts of any cracked tooth
• To restore a broken tooth or a tooth that has been severely worn down
• To cover and support a tooth which has a large filling when there isn’t a lot of tooth still left
• To hold a dental bridge constantly in place
• To cover misshapen or perhaps severely discolored teeth
• To hide a dental implant
• To create a cosmetic modification

For children a crown may be taken on primary (baby) teeth in order to:

• Save a tooth that has been so damaged by decay so it can’t support a filling.
• Protect the teeth of any child at high possibility for tooth decay, especially when a child has difficulty keeping up with daily oral hygiene.
• Decrease the frequency involving general anesthesia for children unable because of age, behavior, or medical history to fully cooperate using the requirements of proper dentistry.

In such cases, a pediatric dentist will probably recommend a stainless metallic crown.
