"The man with a toothache thinks everyone happy whose teeth are sound."

George Bernard Shaw

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.

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.

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.

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.

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 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.

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.

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.

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.

Your cosmetic dentist may have you use a Flipper appliance. A Flipper is a false tooth to temporarily take the place of a missing tooth before the permanent bridge 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 bridge.

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.

There are basically three types of crowns, those made of gold, ceramic crowns and ceramic-veneered gold crowns. Gold and metal-ceramic crowns are extremely durable and are normally used in molars, where the forces from chewing and grinding are most prevalent. Ceramic crowns are used primarily for front teeth, since they can best resemble the natural tooth color.

Definitions

Dental fillings

• Dental fillings are inserted as restorations in the treatment of dental cavities, after drilling out the cavities.

Dental implants

• Dental implants are surgically fixed substitutes for roots of missing teeth. Embedded in the jawbone, they act as anchors for a replacement tooth, also known as a crown, or a full set of replacement teeth.

Dentures

• Removable complete dentures are full-mouth false teeth, which are used when a patient has no teeth left on either the mandibular arch, the maxillary arch, or both.

Veneer

• A layer of tooth-colored material, usually porcelain or acrylic resin, attached to and covering the surface of a metal crown or natural tooth structure.

Anesthesia

• Total or partial loss of sensation, especially tactile sensibility, induced by disease, injury, acupuncture, or an anesthetic, such as chloroform or nitrous oxide.


• Local or general insensibility to pain with or without the loss of consciousness, induced by an anesthetic.


• A drug, administered for medical or surgical purposes, that induces partial or total loss of sensation and may be topical, local, regional, or general, depending on the method of administration and area of the body affected.

Bridge

• A dental bridge is a prosthesis used in place of missing teeth and may be removable or permanently attached.

Dental cavities

• The formation of cavities in the teeth by the action of bacteria; tooth decay.


• Also known colloquially as tooth decay.

Dental crown

• Full-coverage restoration (sometimes incorrectly called a cap) is a prosthetic tooth designed by a dentist and usually created by a lab technician.

Porcelain

• A hard, white, translucent ceramic made by firing a pure clay and then glazing it with variously colored fusible materials.

Stomatology

• The medical study of the mouth and its diseases.

Tooth bleaching
