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. Throughout your life you end up having 2 completely different sets of teeth. The initial set is the baby teeth (deciduous teeth) that eventually fall out. They are whiter, softer, and less sturdy than adult teeth. Hence, they tend to wear out much faster than permanent teeth, but they also fall out to make room for them. Making sure that there's enough space in the vacancy caused by a lost baby tooth is important for healthy adult 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.
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. 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. 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. Composite resin fillings are applied in thin layers, and slowly built up to form the complete filling. A bright dental light will harden each layer before the next is applied. Once your filling is completed, your dentist will use a special paper, articulating paper, to adjust the height of your dental filling and that your bite remains correct. Your tooth is then polished.
There are two main types of dentures. Both Complete Dentures and Partial Dentures are finely crafted, custom-fitted. If you properly maintain your dentures they will appear natural and provide a perfect smile. Additionally, dentures help strengthen muscles controlling your expressions that require the support of your teeth, rid you of pronunciation problems caused by missing teeth and aid with chewing. If you've lost, or are losing, all of your teeth a Complete Denture is something to discuss with your cosmetic dentist. If some of your teeth remain and are healthy, a partial denture may be your way to a great smile. 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.
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. 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.

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.
