Our teeth Most people know that the teeth are the hardest and strongest part of the body. There's more than meets the eye, though. Teeth are actually a living part of your body that has blood vessels and nerves. If you used to judge your teeth like a book by its cover, then you're in for one big surprise. Teeth anatomy is a lot more complicated than you ever thought. The permanent teeth are the second set of teeth that will last the rest of your life. They tend to be more yellow (and not just because of coffee) and are extremely hard. The final set of teeth is made up of 32 teeth, or 16 on each jaw. There are two central incisors for biting, two lateral incisors for biting, two canines for tearing and cutting, four premolars for chewing, and six molars for chewing. Your teeth are by far one of the most important things you use every day. Many people end up neglecting their teeth with improper oral hygiene. You should take care of them by brushing at least twice a day, flossing once per day, and going for regular dental checkups at least twice per year.
Dental fillings At some point or other in ours lives, most of us wind up with a cavity. In most cases, a cavity calls for your dentist to remove the decay and to fill in the tooth area that was removed. There have been a number of advances in the field over the past few years, so if you're one of the lucky ones and haven't had a cavity in a while, you should read up on what is available today so that you understand the choices available to you. If you have a cavity in a tooth, broken fillings, mercury fillings, or amalgam fillings, this type of dental filling is well worth discussing with your dentist. Mercury fillings or amalgam fillings can easily be removed and replaced with far more attractive colored fillings. These fillings actually strengthen your tooth beyond the level it had with the amalgam fillings. A special dental material is then used to open up the pores of your tooth's dentin and roughens up the surface of the exposed enamel. This achieves better and stronger bond. The bond resin is applied to stick the composite to your tooth. This material is made of the same dental resin as the composite however it is much more fluid. This layer is then hardened and cured with a very bright light. If over half of your molar tooth's biting surface is decayed an inlay or onlay may be a better option than a filling. These options are basically for when more than a filling is needed but less than a crown will do. An inlay is placed in between the cusps of the tooth, whereas an only will cover one or more of the cusps. They can be made of a gold alloy, porcelain or tooth-colored resin and are cemented into place.
Dental laminates Veneers provide a durable solution to the color and shape problems that are common to so many people. Veneers are applied to fronts or visible areas of the teeth. The enamel (outside layer of the tooth) is ground down or reduced by just fractions of a milimeter in order to allow for the thin (contact lense thickness) veneer to be permanently attached to the tooth. Teeth enamel discoloration can be caused by staining, aging, or chemical damage to teeth. Some of the more common causes of teeth discoloration are medications, coffee, tea or cigarettes. People who drink significant amounts of cola soft drinks can experience similar staining. While no alternative to veneers will create the exact same effect, there are some popular procedures that may seem worthwhile. Crowns, while more expensive, also act to cover the tooth with a protective coating. For individuals who simply want to brighten their teeth, many clinics now offer tooth bleaching, though this is a much less permanent procedure.
Teeth bridges In areas of your mouth that are under less stress, such as your front teeth, a cantilever bridge may be used. Cantilever bridges are used when there are teeth on only one side of the open space. Bridges can reduce your risk of gum disease, help correct some bite issues and even improve your speech. Bridges require your commitment to serious oral hygiene, but will last as many ten years or more. If you a space from a missing tooth, a bridge will be custom made to fill in the space with a false tooth. The false tooth is attached by the bridge to the two other teeth around the space - bridging them together. Your cosmetic dentist will prepare your teeth on either side of the space for the false tooth. You will be given a mild anesthetic to numb the area, and the cosmetic dentist will remove the an area of each abutment (teeth on either side of the space) to accommodate for the thickness of the crown. When these teeth already have fillings, part of the filling may be left in place to help as a foundation for the crown.
Teeth reshaping Tooth reshaping, or contouring, is one of few instant treatments now available in cosmetic dentistry. Dental reshaping and contouring is a procedure to correct crooked teeth, chipped teeth, cracked teeth or even overlapping teeth in just one session. The dental contouring procedure can even be a substitute for braces under certain circumstances. It is also a procedure of subtle changes. A few millimeters of reduction and a few millimeters of tooth-colored laminate can create a beautiful smile when performed by a cosmetic dentist, with no discomfort to you. Tooth reshaping, or dental contouring, is commonly used to alter the length, shape or position of your teeth. The cosmetic dentist will mark your teeth with a pencil prior to performing the procedure. This helps the cosmetic dentist in their sculpting process. As your cosmetic dentist sculpts the tooth, imperfections are artfully eliminating or minimized. A sanding drill or laser may be used to remove small amounts of surface enamel gradually. Abrasive strips are then moved back and forth between your teeth to shape the actual sides of your teeth. Then the teeth are smoothed and polished. Usually anesthetic is not needed. Teeth contouring and reshaping usually takes one to three visits.
Theeth crowns As we age, many of us find ourselves with teeth that are no longer structurally sound. Root canals, lost fillings, decay below a filling, chipping and cracking of the enamel are all things that can lead to large scale defects in a tooth's surface. When the entire surface of the tooth is a problem, but the root system is intact, a crown might be just what the dentist orders. Grinding your teeth, an improper bite, age, fillings and tooth decay can all be contributing factors in the wearing down, cracking or breakage of your teeth. Dental crowns cover the entire visible surface of your affected tooth and add strength, durability and tooth stability. Your cosmetic dentist will make an impression of the tooth and a dental laboratory will create the crown. You will typically leave the office with a temporary crown to wear while the permanent crown is being made - this takes about two weeks. The permanent crown is then cemented onto your tooth. Typically, only two visits are required for this part of the procedure. Often, a preliminary restoration of your tooth may be needed before a crown can be placed. To stabilize your tooth, a filling must first be put in place prior to placing a crown due to the loss of original tooth structure. Tooth crowns usually last ten to fifteen years.
