A dental crown, which is also known as a “tooth cap” or “dental cap,” is a type of dental restoration that completely covers a tooth or a dental implant. This kind of treatment may be necessary in cases where damage to the tooth is extensive and simple restorative methods such as tooth fillings will not suffice to cover the damage. Dental caps are permanently fixed to the underlying teeth and can function just like natural teeth.
There are many reasons why dental crowns may be placed on the teeth. Besides restoring extensively damaged teeth, they may be used to hold together a weak or cracked tooth. Dental crowns may also be placed to hold a bridge in place or cover up a tooth that has little material left. In addition to being a good replacement for severely broken or rotted teeth, tooth caps may also be placed for cosmetic purposes, such as when teeth are discoloured or misshapen.
Dental crowns may be made out of metal, porcelain, resin, ceramic or a combination of these. Caps that are all-porcelain or ceramic are the best choices for cosmetic use as these are the materials with colours that closely match the natural colour of the teeth. As such, they are best used for capping the front teeth which are highly visible. In addition, these are perfectly suited to people with allergies to metal. However, it is important to note that they are not as strong as other types of crown materials and are thus prone to be worn out, especially if the patient suffers from bruxism or tooth grinding.
A stronger type of dental crown is the porcelain-fused-to-metal type. These can also be used for cosmetic purposes because of the porcelain component. However, the metal component of this type of crown may become visible as a dark line on the gums. This is especially common among those with receding gum tissue. Just like all-porcelain or all-ceramic caps, they are also prone to breaking down and chipping.
All-resin tooth caps are a popular choice because they are inexpensive. However, among all the materials used for caps, they are the most prone to fractures and wearing out. The last material commonly used for dental caps is metal. This is the strongest among all the substances used for dental crowns—they can withstand the forces of biting, do not chip or break, and hardly wear down even after years of use. They do have a major drawback, however, and that is the unsightly colour. These are best for molars that are out of sight of other people.
Tooth Caps do not need special care, but practicing good oral hygiene should be continued.
