Types of Tooth Crowns
Most dentists will agree that the tooth crown is at the heart of general dentistry. They've all studied dental crowns in dental school, and some have done their best work replacing a missing tooth and saving the rest.
Research has given them the wherewithal to achieve virtually ideal restorations. They are natural looking, comfortable and stable in the moist environment of the mouth. Cosmetic dentistry professionals are better equipped now more than ever to build strong, long-lasting and cosmetically superior dental crowns.
What is a dental crown?
A crown (or cap) is a restoration placed over broken teeth or a cracked tooth that cannot sustain a conventional filling. By covering the biting surfaces and sides of the tooth, a dental crown strengthens the damaged tooth by binding together the remaining structures. There are basically three kinds of full-crown restorations that can be placed by your cosmetic dentist, each with pros and cons, depending on your situation.
A gold crown or metal alloy crowns have the longest track record for durability, but some people object to the look of metal.
A full porcelain crown - and its new ceramic cousin - looks wonderful and fits well; however, porcelain crowns are usually best on front teeth where stress is not so great.
Porcelain-fused-to-metal dental crowns are our loyal work-horses for single-tooth restoration - they're very strong.
There are elements of finesse in the creation of any crown. The fit is the thing. The teeth must be prepared with opposing teeth in mind so a good bite won't go bad after the crown is placed. The fit must accommodate adjacent teeth, too. And the "margin," the part of the crown nearest the gum, must fit smoothly to protect the health of gum tissue.
And all this effort is to one end: to save a tooth.
When is a dental crown called for?
- A tooth that has been filled more than once cracks, breaks off, or falls victim to secondary caries - a cavity under or around a filling.
- You've had root canal treatment on a molar, and it's prone to brittleness.
- A tooth has suffered severe enamel wear.
- The high school hockey star takes a blow in the mouth, and an otherwise sound tooth is broken.
- You need an anchor for your new dental bridge.

Cosmetic Dentistry Corrections: Bleaching, Bonding and Dental Veneers
Maybe you've thought about cosmetic dentistry, but felt it was a little vain to consider it. Or the appearance of your teeth never bothered you much, because your dental health is pretty good.
Well, like it or not, "cosmetic" is more than skin deep. Most people form biases about others based on appearance. And, one of the critical factors in such judgments, is the teeth.
Because new cosmetic dental techniques give your dentist the means to fine-tune virtually anyone's teeth, most people need not go without the advantage of a white bright smile. Consider the options.
Teeth bleaching is a simple, inexpensive way to lighten stains and discoloration on certain teeth, front teeth are the more obvious candidates, without altering the natural structure of enamel. If you've had a root canal procedure, there may be some darkening. Some people suffer staining from medications, like tetracycline. And teeth naturally change as we age, or if we indulge in too much coffee, tea or smoking.
In any case, whiter teeth can be achieved with external or internal bleaching. The most common treatment involves cleaning the teeth thoroughly, applying a bleaching solution, and then curing it with a gentle heat source. The procedure takes just 30 to 45 minutes. After three to five sessions, you, and everyone else, will really notice the difference.
Cosmetic corrections for gaps, misshapen or chipped teeth are achieved with tooth bonding. New dental bonding materials can work wonders using a little art, and lots of science. Your cosmetic dentist can literally sculpt tooth form, or replace a gold crown with natural-colored restorations. The result is stronger than ever and makes a dramatic impact on your appearance.
Dental veneers are an option too, for teeth that need lengthening or reshaping. Veneers cover the front of a tooth entirely and work especially well where there is less stress on the teeth involved. Veneers are a durable, beautiful solution to dental imperfections.
