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. 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. 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.
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. The implant procedure is a surgical placement of the implant or implants in your jaw bone which requires a three to six month healing period before the implant restoration to replace the missing tooth or teeth. During this healing time, the bone grows in and around the titanium implant creating a very strong support. Dental implants can be rejected. Usually they are replaced with another implant of a slightly larger size. The rejection or "failure" rate is minimal, only 1 to 2% of all implant procedures. You must go without wearing your dentures for one day to two weeks after an implant placement. After the implant has "taken" and you have sufficiently healed, a very natural crown is placed on the implant. 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.
Dentures are removable replacements for missing teeth typically made out of an acrylic resin which at times incorporate porcelain or metal for additional structural support. There are two main types of dentures. Both Complete Dentures and Partial Dentures are finely crafted, custom-fitted. If you properly maintain your dentures they will appear natural and provide a perfect smile. Additionally, dentures help strengthen muscles controlling your expressions that require the support of your teeth, rid you of pronunciation problems caused by missing teeth and aid with chewing. If you've lost, or are losing, all of your teeth a Complete Denture is something to discuss with your cosmetic dentist. If some of your teeth remain and are healthy, a partial denture may be your way to a great smile.
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. 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. Dental veneers can be made from porcelain or from resin composite materials. Porcelain veneers resist stains better than resin veneers and better mimic the light reflecting properties of natural teeth. Resin veneers are thinner and require removal of less of the tooth surface before placement. You will need to discuss the best choice of veneer material for you with your dentist. Veneers, porcelain or plastic, are placed over the front teeth to change color shape of the teeth. Veneers are ideal for teeth that are too small, too big, or have uneven surfaces. It is very common for people to have imperfect teeth, either oddly shaped teeth, chipped teeth, crooked teeth, teeth with small holes in them, or an inappropriate sized tooth or teeth that have an odd appearance. Veneers solve such irregularities and create a durable and pleasing smile.
Basically, bonding will cover any natural flaws applying a thin coating of a plastic material on the front surface of your teeth. After this, your cosmetic dentist will apply a bonding material and sculpt, color and shape it to provide a pleasing result. A high-intensity light then hardens the plastic, and the surface is finely polished. 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. 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.
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. The dentist will then make an impression, which will serve as the model from which the bridge, false tooth and crowns will be made by a dental laboratory. A temporary bridge will be placed for you to wear while your bridge is being made until your next visit. This temporary bridge will serve to protect your teeth and gums.
For individuals who have chipped, cracked or irregularly shaped teeth, dental contouring and reshaping can be just the ticket for a more beautiful smile. 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. 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.
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. 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. In some cases your cosmetic dentist may choose to use a Flipper instead of a temporary crown. A Flipper is a false tooth to temporarily take the place of a missing tooth before the permanent crown is placed. A Flipper can be attached via either a wire or a plastic piece that fits in the roof of your mouth. Flippers are meant to be a temporary solution while awaiting the permanent crown.
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. 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. Some tenderness and soreness is to be expected with any method of teeth straightening, especially soon after an adjustment is made. The bone on one side of each tooth socket will be compressed, and the other side must be filled in with new bone as the tooth moves through the jaw. Standard orthodontic braces may cause superficial irritation to the interior of the mouth, a symptom that can be reduced with salt water gargles and a soft wax on the surface of the brackets. Severe side effects to teeth straightening are nearly unheard of, and the process is considered very safe.
