"Gold that buys health can never be ill spent."

Thomas Dekker, Westward Ho, 1604

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.

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.

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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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.

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.

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.

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.

Dental reshaping and contouring is a procedure to correct crooked teeth, chipped teeth, cracked teeth or even overlapping teeth in just one session. This procedure is even a substitute for braces under certain circumstances. This is also a procedure of subtle changes. A few millimeters of reduction and a few millimeters of tooth-colored 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.

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.

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.

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 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.

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.
