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. 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.
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. 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. When missing one tooth, your cosmetic dentist may use a Flipper to fill the space. A Flipper is a false tooth to temporarily take the place of a missing tooth before the permanent crown is placed on the implant. 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 to be placed on your implant(s).
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. There are many different causes that lead to stained or discolored teeth. Some of the most common causes are everyday foods and drinks--coffee, tea, soda, and red wine all have a staining effect on tooth enamel. Smoking will also darken teeth. Some medications, if taken during early childhood, can result in teeth that are discolored. 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.
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. 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.
Bonding is a composite resin filling placed in the back teeth as well as the front teeth. Composites are the solution for restoring decayed teeth, making cosmetic improvements and even changing the color of your teeth or the reshaping of teeth. Bonding will lighten any stains you may have, close up minor gaps and can be used to correct crooked teeth. 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.

Definitions and termsDental 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
- Also known as tooth whitening.
