A crown is a cover or “cap” that is placed over a tooth. The crown restores the tooth to its normal shape, size, and function. A crown can make the tooth stronger or improve the way it looks.
When the crowns cemented into place, it fully encase the entire visible portion of a tooth that lies at and above the gum line.
What is crown made from?
Crowns are made from several types of materials. Metal alloys, ceramics, porcelain, porcelain fused to metal, or composite resin may be used. When a crown is made, the material often is colored to blend in with your natural teeth.
dentists want your crown to look natural and fit comfortably in your mouth. To decide which material to use for your crown, your dentist will consider many factors, such as:
- the tooth’s location and function
- the position of the gum tissue
- your preference
- the amount of tooth that shows when you smile
- the color or shade of the tooth
Reasons you may need a crown:
- protect a weak tooth (for instance, from decay) from breaking or to hold together parts of a cracked tooth.
- restore an already broken tooth or a tooth that has been severely worn down.
- protect the restored tooth in case of root canal treatment.
- cover and support a tooth with a large filling when there isn’t a lot of tooth left.
- hold a dental bridge in place.
- cover misshaped or severely discolored teeth.
- cover a dental implant.
- make a cosmetic modification.
What Problems Could Develop With a Dental Crown?
- Discomfort or sensitivity:
Your dentist may recommend that you brush teeth with toothpaste designed for sensitive teeth.
- Chipped crown:
Crowns made of all porcelain or porcelain fused to metal can sometimes chip, if the chip is small, a composite resin can be used to repair the chip with the crown remaining in your mouth.
- Loose crown:
Sometimes the cement washes out from under the crown, not only does this allow the crown to become loose, it allows bacteria to leak in and cause decay to the tooth that remains.
- Crown falls off
Sometimes crowns fall off, reasons include decaying of the underlying tooth and loosening of the cementing material used to place the crown, if your crown falls off, clean the crown and the front of the tooth. Contact your dentist’s office immediately.
- Allergic reaction
Because the metals used to make crowns are usually a mixture of metals, but this is extremely rare.
- Dark line on crowned tooth next to the gum line:
This dark line is simply the metal of the crown showing through, while not a problem in itself, but it is cosmetically unacceptable.
How Long Do Dental Crowns Last?
On average, dental crowns last between five and 15 years. The life span of a crown depends on the amount of “wear and tear” the crown is exposed to, how well you follow good oral hygiene practices, and your personal mouth-related habits.
Caring for Dental Crown:
Like natural teeth, crowns can break. And, the tooth under the crown can still get cavities. To prevent cavities or damage to your crown:
- Brush your teeth twice a day and clean between your teeth every day.
- Avoid chewing hard foods, ice, or other hard objects, such as pencils, especially if you have tooth-colored crowns.
- Be sure to see your dentist for regular exams and professional teeth cleanings.
