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. Your teeth are by far one of the most important things you use every day. Many people end up neglecting their teeth with improper oral hygiene. You should take care of them by brushing at least twice a day, flossing once per day, and going for regular dental checkups at least twice per year. 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.
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. Your dentist will give you a local anesthetic to numb the area. The dentist then prepares an access to the decayed area of the tooth and removes the decayed portions. This is accomplished with traditional drills, micro air abrasion or even with a dental laser. With a composite filling, your dentist will preserve more of the natural tooth as the composite resin can be bonded to the tooth in thin layers. If your tooth's decayed area is close to a nerve, a special liner will be used to protect the nerve. 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.
You maybe candidate for tooth contouring and reshaping, if you want your teeth to appear less crowded, lack chips and fractures, have decreased overlaps or to be without pits or grooves in the enamel, this procedure should be discussed with your cosmetic dentist. Tooth reshaping, or tooth sculpting, is a safe and conservative way to improve your smile. Teeth may become weaker if large amounts of enamel are removed, tooth reshaping should be limited to minor changes or combined with veneers or bonding for the best smile. Contouring teeth may also help correct small problems with bite. It is common for bonding to be combined with tooth reshaping to achieve a beautiful smile. There are actually several ways to change the appearance of your teeth. Many times these various procedures are combined in different ways to deliver that smile of your dreams.
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. 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. 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.
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. The most common method of teeth straightening remains standard orthodontic braces. Archwires, springs, and rubberbands apply pressure to the individual teeth by means of brackets that are glued onto their surface. Regular visits are required to the orthodontist in order to tighten wires as needed and make other adjustments. At each visit, the wires will be tightened slightly to renew pressure and push them toward their intended position. Additional wires, rubberbands, and headgear may be prescribed to help move the teeth into their ideal position as quickly as possible. When the teeth have all been repositioned, the brackets will be removed and a retainer must be worn to prevent relapse for some period of time.
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.
