Your teeth

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.

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.

Fillings for dental cavities

Composite resin dental fillings were created as an alternative to traditional metal dental fillings. Tooth fillings colored to look like a natural tooth are known as Composite Resin Dental Fillings,are made of a plastic dental resin. Composite Resin Dental Fillings are strong, durable, and make for a very natural looking smile. Many dental insurance plans cover their use.

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.

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.

Dentures as false teeth

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.

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.

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.

Dental contouring and reshaping

For individuals who have chipped, cracked or irregularly shaped teeth, dental contouring and reshaping can be just the ticket for a more beautiful smile.

Tooth reshaping, or contouring, is one of few instant treatments now available in cosmetic dentistry. Dental reshaping and contouring is a procedure to correct crooked teeth, chipped teeth, cracked teeth or even overlapping teeth in just one session.

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.

The cosmetic dentist will mark your teeth with a pencil prior to performing the procedure. This helps the cosmetic dentist in their sculpting process. As your cosmetic dentist sculpts the tooth, imperfections are artfully eliminating or minimized. A sanding drill or laser may be used to remove small amounts of surface enamel gradually. Abrasive strips are then moved back and forth between your teeth to shape the actual sides of your teeth. Then the teeth are smoothed and polished. Usually anesthetic is not needed. Teeth contouring and reshaping usually takes one to three visits.
