Crowns are full coverage restorations that are used to cover a tooth that is likely to break, or is too broken down to be restored with a filling. They are most commonly done after root canal treatment, or when a tooth fractures. The larger the hole made by a cavity that has to be treated, the more likely a crown will be needed. Even after a filling is put in a large cavity, a tooth is more likely to break. Keep in mind that the jaw muscles are the strongest in the human body. Teeth are subjected to tremendous pressures. Crowns cover the weakened tooth, providing strength and protecting the tooth against breakage. A broken or cracked tooth is a far more serious matter and much more difficult to treat. Crowns prevent this, as well as making for a nice smile.
There are many types of dentures, but they share a common function. They replace teeth that have become loose or been lost due to bone loss. When bone loss around the roots of teeth is great enough to loosen them or let them fall out, it's time for dentures. No one enjoys losing their natural teeth, but dentures allow you to keep some of the funcionality of your natural teeth.
The entire mouth is examined and a determination is made as to which teeth will have to be removed, and which will remain. The loose teeth are then extracted. Dentures are fitted to go over or around whatever teeth remain in the mouth, depending on the type. There is an adjustment period after dentures are placed in the mouth, and it can take some getting used to. But once accustomed to the dentures, most of the normal functionality and appearance return as you adapt to your new smile.
A dental implant is an option to replace a missing tooth. In this procedure, a small titanium shaft is surgically implanted into the bone and allowed to set. The bone grows around it forming a tight connection, which additionally slows or stops the bone loss that occurs when the root of a natural tooth is missing. Once the implant is firmly set in the mouth, the dentist then works to attach the replacement tooth onto the top of the shaft. This permanent solution has the advantages over bridge work that it does not stress the surrounding teeth for support and tends to be a more predicatable treatment option.
ROOT CANAL TREATMENT
A root canal is then performed to clean out the infected tooth pulp, and the canals are disinfected. Once the infection is resolved, the canal(s) are filled in to prevent any further infection. At this point, it is highly recommended that the tooth have a post and core and a crown to protect it from fracturing.
This is an option for filling the space created by a missing tooth. It involves preparing the teeth on both sides of the space for crown abutments and having a pontic, or fake tooth, attached in the middle to replace the missing tooth. This bridge replaces the missing tooth, both functionally and cosmetically. Bridge work is as much an art as it is an exact science. The materials used may be gold alloys, porcelain bonded to metal alloy, or all ceramic material. The choice of material depends on requirements for strength, wear, and/or esthetics.
It is important that a missing tooth be replaced as soon as possible. Teeth tend to move forward if there is a space allowing them to do so. This can lead to the healthy teeth shifting in such a way that they can create problems in your mouth that may be difficult to improve.
Problems in this area can cause:
Dental treatments for this condition can include replacing missing teeth, moving teeth, adjusting the bite, filling gaps between teeth, etc. There is no one solution that is right for all cases. Sometimes a plastic mouthpiece is used to prevent clenching or grinding that is contributing to the problem. If untreated and taken to extremes, surgery may be required to repair a badly damaged joint.
