Our teeth 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.
Dental implants tomorrow Tooth loss is something no one looks forward to. If you lose one or more teeth, you have a number of options, one of which is dental implants. You owe it to yourself to be informed as possible about these options. With this in mind, we've created this section on dental implants. Begin learning more about dental implants for tooth replacement exacltly now! 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'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.
Tooth dentures 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.
Methods of teeth straightening 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. 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.
Terms and definitionsDental 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.
