How do I get a cavity under my crown(Dental cap)? How long does a crown(cap) last?
A crown, or dental cover, is a form of dental rebuilding that entirely caps or encloses a tooth or dental implant. A crown could be required when a large cavity threatens the health of a tooth. They are classically fused to the tooth by dental cement. The crown reinstates the tooth to its normal shape, size, and purpose. Crowns are made up of several types of materials. Metal alloys, ceramics, porcelain fused to metal, porcelain, or composite resin could be used. When a crown is made, the material usually colored to merge with your natural teeth.
This is a very reasonable question if you are not familiar with the actual process and design of a crown cemented to a tooth.
First, a crown does not get a cavity. The cavity starts on the root at the crown/tooth junction. Second, any tooth structure can get decay regardless of your age. Third, as the tooth approaches the gums and its diameter decreases. That means that the nerve is closer to the outside surface of the tooth.
Avoid eating chewy food, such as chewing gums and caramels. Reduce chewing force on the temporary crown. Don’t eat hard food, it has the potential to break your crown. Clean your gums frequently, as they can be tender after the treatment. Use dental floss carefully.
Crowns are usually made of ceramic or a mix of metals. These materials don’t cause stains and plaque. Though, any crown has an edge where it meets with the tooth. Dentists try to make this edge plane, but it is not able to achieve a perfectly smooth surface. This area should be cleaned thoroughly as it has the potential to develop cavity or gum disease. Brush your teeth twice a day with fluoride toothpaste, floss them with a super floss and use interdental cleaners to remove plaque. If you have an aptitude for developing cavities, your dentist can prescribe a special high-fluoride gel to use at night to prevent teeth decay.
Reduce Biting Force;
Crowns are not as strong as your own healthy teeth. So, avoid biting hard substances and fingernails this may damage your crown. There are also other risk factors that may cause the crown’s damage: bruxism (teeth grinding), sports activities, stress that is often followed by clenching and grinding the teeth. In case you have bruxism, you may be prescribed to wear a nightguard during sleep. When playing sports, mouth guards are available to guard your crowns, other restorations as well as intact teeth.
The location of the cavity under a crown will dictate the treatment for the tooth. If the cavity is on the outside near the cheeks, it may be able to be patched and not remake the entire crown at this point. If it is in between then the crown and adjacent tooth, the crown should definitely be replaced. Crowns typically last between 5 and 20 years. Some crows may fail sooner and some may last longer.
If your crown is broken, contact your dentist.
