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.

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.

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.

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.

Implants are great for replacing missing teeth. It is important that you have enough bone in the area of the missing teeth for the implants to be attached to. Implants are not only used to replace one tooth, but rather people missing most, if not all, of their teeth benefit greatly as well. Implants are increasingly being used to replace certain types of bridges and removable partial dentures.

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.

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.

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.

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.

For individuals who have chipped, cracked or irregularly shaped teeth, dental contouring and reshaping can be just the ticket for a more beautiful smile.

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.

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 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.

Dentists are able to provide much more dramatic teeth whitening. Some patients opt for a take-home kit that provides results in a few days, while others choose a one-hour procedure that uses advanced technologies to immediately bleach teeth several shades lighter. Take-home kits usually involve custom-fit trays with a whitening gel of carbamide peroxide, to be worn for several hours at a time over some number of weeks as determined by the dentist. These kits are usually less expensive than the one-visit whitening procedures.

For individuals who are looking for a fast way to achieve dramatic teeth whitening results, in-office whitening is the way to go. Protective gel is applied to the gums, lips and other tissue around the teeth, and then a bleaching solution is applied to the tooth enamel. A high intensity laser or other type of light catalyzes the bleach, and the teeth are treated for one to two hours.

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.

Most of us have had amalgam fillings (silver) or gold filling restorations. Some amalgam fillings were what we have called mercury fillings, as some amalgam fillings contained mercury. Metal fillings were effective, but very conspicuous and tended to blacken in color over time.

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.

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.

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.

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.

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.

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.

This procedure should be thoroughly discussed with your dentist as there are several personal and medical factors to take into consideration. You may instead be a candidate for dental bridges and dental implants as optional procedures.

The setting up dentures procedure begins with a wax bite impression of your mouth that will give your dentist exacting measurements. A try-on appointment will fine tunes color, shape, and custom-fit. After your final dentures are fabricated, they will be placed and informed of their required care.

The main component of dentures is acrylic resin molded over the top of various combinations and paterns of metal. In oreder to use dentures all of the teeth in the top or bottom or both top and bottom of the mouth are removed. It is recomended that after the removal of the necessary teeth that the patient wait at least a month to have the dentures fit to the mouth. The waiting period allows for proper healing in the mouth to take place.
