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.
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.
