Dental Crowns

As we grow older, more often than not we begin to notice that our teeth are not as strong as they were in the past. Many years of day to day usage begins to take its toll and past procedures play a role too. Previous Root Canals, older fillings becoming loose, overall decay along with fractured and chipped teeth all impact our long term dental health. The exposed tooth may be damaged but when the root is still viable, a crown may be your best solution. When natural teeth begin to show signs of distress, a dental crown can hide the entire visible portion of your worn teeth. They strengthen and stabilize your teeth and make your bite far more effective. Your dentist will make a mold of the questionable tooth, sending it to the dental laboratory to have a new one manufactured that fits with precision. While waiting for the permanent crown, an impermanent crown will stand in until the new one is prepared. The new crown is fitted and fastened to the old structure and this normally takes place over two visits to the dentist. Periodically, some preparatory work needs to be completed on the old tooth prior to installing the crown. A crown can last for more than ten to fifteen years with proper maintenance. Before bonding techniques became popular, the dental crown was usually developed using a metal under foundation. Today dentists are utilizing porcelain in its purest form or some variation of ceramic compound. Occasionally the rear molars necessitate using the metal foundation for stability and sturdiness. The issue arises that when smiling the metal is noticeable so a natural appearance is the best option.

Variations of the Porcelain Crowns
The Cerec Crown is just one of those variations of the full porcelain type of crown. It is made entirely from ceramic compound. Rather than being manufactured in the dental laboratory via a technician, this kind of crown is actually designed by computer and produced in the dentist's office. The issue with this process is that the crown is limited aesthetically by the creative gifts of the dentist! The Empress Crown is also entirely made of porcelain using the Empress pressed ceramic product. There are other all ceramic crown products including Procera, In-Ceram, Zirconia, and Feldspathic porcelain. A knowledgeable dentist will understand each variation of the porcelain dental crown. Each of these varieties has pros and cons based on particular requirements, therefore it is important that you heed the advice of your dentist and only choose what they decide upon. Porcelain combined to Metal Crowns has the natural look about them but they come with concerns to be aware of. Due to the metal foundation, they require using what is known as an opaquer to obscure the metal. Consequently, it will not be possible to achieve the natural appearance of the teeth. In time, a dark outline will become noticeable along the perimeter of the gum line. Your dentist will try and hide this line below the gum perimeter however, this is not always possible. Periodically, the shadowy line won't be noticeable when the crown is initially set in place but it tends to appear afterwards when the gum begins to retreat. Your dentist might try what is called a porcelain butt margin that may reduce the darkened line but it will not entirely eliminate it. These crowns are used regardless due to their superior strength and stability over any other porcelain variations.
