Our teeth 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. Excellent crowns and bridges were made by the Etruscans in the 7th cent. B.C. At about that time, teeth were being extracted in Asia Minor as a cure for bodily ills and diseases. Skills achieved by the Etruscans, Phoenicians, Egyptians, Greeks, and Romans were largely lost during the Middle Ages, when barbers and roving bands of charlatans practiced unskilled dentistry at marketplaces and fairs. Abulcasis, a Spanish Moor, was one of the few in his time who studied dental surgery. 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.
Tooth veneers This section of our cosmetic dentistry information site provides you with some background into dental veneers, both composite veneers and porcelain veneers. Dental veneers, sometimes called tooth veneers, can be used to correct both color and shape problems. There are several corrections that you can make to the color of your teeth as well as the shape of your teeth! Some of the causes of tooth discoloration are staining, aging, chemical damage, disease, medication, and genetics. Dental Veneers (Tooth Veneers) are used to correct both the color and the shape of teeth. 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. Dental veneers (sometimes called porcelain veneers or dental porcelain laminates) are wafer-thin, custom-made shells of tooth-colored materials designed to cover the front surface of teeth. These shells are bonded to the front of the teeth changing their color, shape, size or length and resulting in an improved appearance.
Fillings for dental cavities 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. Your dentist will give you a local anesthetic to numb the area. The dentist then prepares an access to the decayed area of the tooth and removes the decayed portions. This is accomplished with traditional drills, micro air abrasion or even with a dental laser. With a composite filling, your dentist will preserve more of the natural tooth as the composite resin can be bonded to the tooth in thin layers. If your tooth's decayed area is close to a nerve, a special liner will be used to protect the nerve. Composite resin fillings are applied in thin layers, and slowly built up to form the complete filling. A bright dental light will harden each layer before the next is applied. Once your filling is completed, your dentist will use a special paper, articulating paper, to adjust the height of your dental filling and that your bite remains correct. Your tooth is then polished. There are no known health risks of receiving composite fillings. If such a filling is not going to be enough to protect your damaged tooth, or if your tooth enamel is thin and will easily fracture, or if your tooth has had a root canal that weakened your tooth condition, your tooth may require additional protection such as a crown.
Tooth crown procedure 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. In other instances, crowns are used to replace a actual missing tooth. These crowns are anchored to the teeth on either side, with a bridge section connecting the two crowns. Instead of bridges, single tooth dental implants may be used that eliminate the need for supporting the crowns. 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 implants tomorrow If you're missing one tooth or all of your teeth, implants may well be for you. So long as you have enough bone in the area of the missing tooth to facilitate the anchorage of the implants, this procedure can yield terrific results. If you don't have enough bone for this purpose, a bone graft may be necessary. If you have a small dental bridge or partial dentures (removable type), implants will be a welcome alternative. Implants are an alternative to a fixed bridge. The implant will last a lifetime, but the crown on top of it will last ten to fifteen years. Implants are surgically placed in your jaw bone while under anesthesia. It is a very time consuming procedure when having many implants placed. As this procedure is surgical, it is very important to research and find a well credited cosmetic dentist that you are comfortable with. For some people there are varying degrees discomfort or pain, which subsides in a couple of days. As with similar types of surgery, bruising and minor swelling might also develop shortly after the procedure. If you're missing one tooth or all of your teeth, implants may well be for you. So long as you have enough bone in the area of the missing tooth to facilitate the anchorage of the implants, this procedure can yield terrific results. If you don't have enough bone for this purpose, a bone graft may be necessary. A procedure of building up the bone is known as Bone Grafting. Bone grafting is common with dental implants. The bone that is used is one of three types. The preferred bone to use is taken from other areas of your mouth or collected in a suction device as the drilling of the sites for dental implants occurs. Sometimes bone is taken from areas such as a hip (this requires an orthopedic surgeon and an operating room). The third source for needed bone is a synthetic type. This is the least preferred type of bone to be used for this procedure.
Dental contouring and reshaping You maybe candidate for tooth contouring and reshaping, if you want your teeth to appear less crowded, lack chips and fractures, have decreased overlaps or to be without pits or grooves in the enamel, this procedure should be discussed with your cosmetic dentist. With a little dental contouring, you can make a huge difference in the way you feel about your smile. Good cosmetic dentistry can give you a smile that is the envy of others. Tooth contouring by a cosmetic dentist does require that you have normal, healthy 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. Contouring teeth may also help correct small problems with bite. It is common for bonding to be combined with tooth reshaping to achieve a beautiful smile. There are actually several ways to change the appearance of your teeth. Many times these various procedures are combined in different ways to deliver that smile of your dreams.
Teeth whitening While there is no medical need to whiten teeth, it is a procedure that can have a big impact on a person's self-esteem. Severely yellowed or discolored teeth can make a person self-conscious and reluctant to smile. 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. Some types of tooth discoloration are difficult to whiten and treat. Teeth that have been subjected to trauma may darken significantly, and resist any bleaching procedure. Some medications affect young children when their teeth are first forming and may also be nearly impossible to treat. Dentists will be able to tell what situations may result in bleach-resistant discoloration, and provide advice on how effective various treatments may be. In cases of extreme discoloration that cannot be subjected to common teeth whitening procedures, porcelain veneers applied to the teeth may be an alternative solution.
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. The resin comes in many shades so that we can match it to your natural teeth. Due to the layers involved, this procedure will take slightly longer than traditional silver fillings because multiple layers of the bonding material are applied. Typically bonding takes an hour to two hours depending on your particular case. You are good candidate for tooth bonding, if you have close, small gaps between your front teeth, or if you have chipped or cracked teeth, you may be a candidate for bonding. Bonding is also used for patients who have discolored teeth, uneven teeth, gum recession or tooth decay. Bonding material is porous, so smokers will find that their bonding will yellow. If you think you are a candidate for bonding, discuss it with your dentist.
Dental 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. You maybe candidate for dental bridges, if you have missing teeth and have good oral hygiene practices, you should discuss this procedure with your cosmetic dentist. If spaces are left unfilled, they may cause the surrounding teeth to drift out of position. Additionally, spaces from missing teeth can cause your other teeth and your gums to become far more susceptible to tooth decay and gum disease. 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.
Methods of teeth straightening Teeth straightening is accomplished with a number of different procedures and is usually done on children and adolescents when their permanent teeth begin growing in. Crooked teeth, crowded teeth, and even overbites and underbites can be treated with various teeth straightening techniques. While considered a cosmetic procedure, some people require teeth straightening in order for their teeth to be aligned in such a way that chewing is possible. Severe overbites and underbites can result in serious consequences over time, and even overly crowded teeth can mean health problems for the mouth. 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. The most common method of teeth straightening remains standard orthodontic braces. Archwires, springs, and rubberbands apply pressure to the individual teeth by means of brackets that are glued onto their surface. Regular visits are required to the orthodontist in order to tighten wires as needed and make other adjustments. At each visit, the wires will be tightened slightly to renew pressure and push them toward their intended position. Additional wires, rubberbands, and headgear may be prescribed to help move the teeth into their ideal position as quickly as possible. When the teeth have all been repositioned, the brackets will be removed and a retainer must be worn to prevent relapse for some period of time.
