A veneer is a layer of tooth coloured material, usually porcelain, which is cemented to the facial surface of the tooth. Veneers are also used to improve the appearance of teeth, particularly if they are discoloured; eroded or surface abrasions are evident. A veneer may be placed on one or more anterior teeth to improve the colour of the teeth or perhaps to close in a large gap between teeth. This procedure is much less invasive than a full coverage restoration and it preserves the natural structure of the tooth.
If a veneer becomes chipped or discoloured it can easily be replaced. A patient should avoid biting on hard substances such as ice, bones, and hard vegetables that could fracture the veneer. The result of cosmetically bonded veneers is aesthetically pleasing and there is no discomfort during the procedure.
A crown (sometimes referred to as a cap) is a full coverage restoration that restores the anatomical surfaces of a damaged or fractured tooth to their original contour and function. The anatomical surfaces are the parts of the tooth that you can see above the gum line. Typically, this type of restoration is recommended when there is very little tooth structure left to restore. The retention of filling material is poor without adequate surface to which the material will adhere. This results in the tooth requiring both constant and frequent repair.
A crown is permanently cemented onto the prepared tooth structure. This type of restorative procedure is often a dentist’s treatment of choice because of the excellent clinical results achieved in creating a strong, permanent restoration. The aesthetic quality of these restorations enhances the overall appearance of the smile, one of our most important communicative features.
The two types of crowns that are commonly used are:
1. Porcelain fused to metal - This type of crown is often used on posterior teeth due to the strength that the semi-precious metal can provide during chewing. The veneer or facing of the tooth consists of porcelain that gives the restoration a natural looking quality.
2. Porcelain crown - This is a very thin shell covered by layers of porcelain to resemble the shading and translucency of a natural tooth. This restoration is often recommended for anterior teeth.
A patient will benefit from this procedure by having a permanently restored, functional and aesthetically pleasing tooth that blends in with the remainder of your natural teeth.
Every tooth in your mouth provides support, structure and function to the jaw. Absence of even a single tooth can cause the adjacent teeth to drift into the position of the missing tooth. Sometimes only the roots will drift causing pressure on neighbouring teeth and reducing the support of other teeth. This drifting is only evident on a dental x-ray.
A bridge is a dental prosthesis that is used to replace one or more missing teeth in the same arch. A bridge is permanently cemented into the mouth; therefore, you cannot remove it. It provides solid support to the structure of the jaw and prevents adjacent teeth from shifting.
Although a partial removal denture can also replace a missing tooth, it can compromise the health of the underlying gum tissue and cause bone loss. A permanently cemented fixed bridge will provide support to the jaw and protect the integrity of the gums. You will benefit by enjoying a permanently restored, functional and aesthetically pleasing bridge that replaces the missing tooth or teeth within the dental arch. You will never have to be concerned with ill-fitting partial dentures again.
