Teeth as sparkle your smile 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 visible part of a tooth, otherwise known as the crown, is only a small portion of the living system. The crown is made up of enamel, the hardest substance found within the body. It is bone that has been enriched with large percentages of calcium. That's why people who drink lots of milk or take calcium supplements have strong bones and teeth. The enamel is thickest at the crown, and thinnest near the roots of the teeth. New developments include the implantation of artificial teeth or binding posts into the gums or jawbone; antibiotic fiber for periodontal disease; root canal surgery, a procedure that ameliorates pain while permitting teeth to remain in place; and nearly painless lasers to repair dental cavities, usually making local anesthesia unnecessary.
Colored tooth fillings Composite resin dental fillings were created as an alternative to traditional metal dental fillings. Tooth fillings colored to look like a natural tooth are known as Composite Resin Dental Fillings,are made of a plastic dental resin. Composite Resin Dental Fillings are strong, durable, and make for a very natural looking smile. Many dental insurance plans cover their use. 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. Composite resins may also be used to enhance the appearance of any tooth, which is a tooth bonding procedure. The composite resin will strengthen and enhance the natural tooth structure as it does with use as a dental filling. 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.
Teeth bridges A dental bridge is a false tooth, known as a pontic, which is fused between two porcelain crowns to fill in the area left by a missing tooth. The two crowns holding it in place that are attached onto your teeth on each side of the false tooth. This is known as a fixed bridge. This procedure is used to replace one or more missing teeth. Fixed bridges cannot be taken out of your mouth as you might do with removable partial dentures. 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. 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.
Tooth crown procedure 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. Your cosmetic dentist will usually be able to spot problem areas in your mouth that might lead to tooth damage and a need for crowns. Chewing patterns play a big role as well. By selectively grinding the tips of your middle and back teeth (called cusps) will alter your bite to reduce the stress on at-risk teeth. 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. Be sure to discuss with your cosmetic dentist that the cement color used for your permanent crown will be the same as used for your temporary crown. A try in paste is used for this purpose. The color of the cement does affect the overall color of a porcelain crown, so this needs to be discussed long before your temporary crown is placed.
Dental bonding The dental bonding procedure utilizes a composite resin and is used for a variety of structural as well as cosmetic purposes. One can draw a parallel between dental bonding materials and a sculptor's clay. By using dental composite resin bonding your dentist can restore chipped or broken teeth, fill in gaps and reshape or recolor your smile. Bonding is a composite resin filling placed in the back teeth as well as the front teeth. Composites are the solution for restoring decayed teeth, making cosmetic improvements and even changing the color of your teeth or the reshaping of teeth. Bonding will lighten any stains you may have, close up minor gaps and can be used to correct crooked teeth. A very mild etching solution is applied to your teeth to create very small crevices in the tooth's enamel structure. These small crevices provide a slightly rough surface permitting a durable resin to bond materials to your teeth. The resin is then placed on your tooth and high-intensity light cures the resins onto your tooth's surface - with each individual layer of resin hardening in just minutes. When the last coat has been applied to your tooth, the bonded material is then sculpted to fit your tooth and finely polished.
The need for teeth whitening Teeth whitening can be accomplished many different ways. Considered a cosmetic procedure, teeth whitening has become very popular in recent years with the development of various methods that range from drugstore products to dental visits. There are many different causes that lead to stained or discolored teeth. Some of the most common causes are everyday foods and drinks--coffee, tea, soda, and red wine all have a staining effect on tooth enamel. Smoking will also darken teeth. Some medications, if taken during early childhood, can result in teeth that are discolored. The simplest type of teeth whitening is the use of products that can be picked up from the drugstore. These products, which use a very mild bleaching solution, usually require extended use over a period of several weeks. They may be brushed on, squeezed into one-size-fits-all trays, applied as strips, or used in conjunction with normal toothpaste and mouthwash. While these products are very popular, their mildness makes them less effective. Mild side effects are to be expected with any teeth whitening procedure, and may range from slight discomfort to sensitivity to hot and cold. While serious side effects are extremely rare, any extended sensations of pain should immediately be reported to a dentist. Irritation to the gums and mouth tissues should also be watched for and reported if persistent.
Methods of teeth straightening The classic metal orthodontic braces are the most familiar method of teeth straightening. Consisting of a bracket glued to the front of each tooth and a metal wire connecting them, orthodontic braces usually require several years of wear for effective teeth straightening. They can be uncomfortable, expensive, and embarrassing for older patients. However, they are still the most effective method of teeth straightening and can correct overbites and underbites as well as individual teeth alignment. Lingual braces are similar to classic orthodontic braces but are attached to the backside of the teeth, rather than the front. Although they still have many of the problems of standard braces, they are not visible and may be chosen by adults who do not wish for visible braces. Lingual braces are more expensive than standard braces but the fastest method of "invisible" teeth straightening. Invisalign is one of the newest methods of teeth straightening and is extremely popular with adults. Consisting of a clear mold that is nearly invisible when worn, Invisalign uses a series of molds that gradually push the teeth into the desired shape. Invisalign does not cost significantly more than standard orthodontic braces, but cannot correct an overbite or underbite and is only a good choice for minor straightening. Invisalign is not as effective on major problems, which may require standard braces.
