When a tooth is cracked or chipped and the root remains intact, your dentist may build a crown to help preserve the remainder of the tooth and the overall structure of your teeth. But just like the ones you wear on your head, not all are built the same.
Here are the most common types of crowns:
Gold crowns are the strongest of all types, and are usually the most expensive. Because of the flashy nature of the gold alloy, this type of crown is usually reserved for the molars at the back of the mouth, hidden from view.
Other types of metal crowns include stainless steel, which is used primarily for temporary crowns because of its softness, and other types of metal alloys including chromium and nickel. Beyond strength and durability, metal crowns require less tooth restructuring than other crown materials and so much of the existing tooth and neighboring teeth remain intact.
Popular choices for crowns nowadays include all-porcelain or all-ceramic. The biggest advantage to porcelain crowns over metal is that they can be matched to existing teeth. However, a big disadvantage is that they require more preparation of the tooth and surrounding teeth and they don’t last as long as metal. Sometimes, the porcelain types can be combined with a metal base for extra strength, but then you sacrifice a little in terms of aesthetics.
Resin is another popular choice for crowns. It, too, can be matched to the color of your teeth. But resin crowns can be prone to cracking and chipping, and with this type you may find yourself having to replace the crown sooner than you’d like.
The type of crown you ultimately choose is going to be based on where the crown is located in your mouth, the price and durability. Also, if you have any metal allergies, your dentist will probably have you rule out gold and other alloys.

Dental crowns are often used to improve the appearance of teeth that have become chipped, cracked or discolored, either from injury or decay. A dental crown is also used to restore the strength and structure to a tooth following a root canal procedure, or to replace missing teeth with the application of a crown over an implant. Crowns can be manufactured from several different materials, each varying in durability or cosmetic appeal. Crowns made from metal are the strongest and longer lasting option available; of which, gold is certainly one.
Why choose gold? Gold is non-toxic, non-corrosive and hypo-allergenic. Gold crowns will not break or chip, even when polished. The greatest advantage of getting a gold crown is its longevity. Gold crowns will outlast those made with other materials at least three to five times longer. You can count on your gold crown to literally last for decades, which may be more cost effective than having to replace crowns of lesser durability.
Since gold is a high noble metal (as opposed to nickel or tin), there is less expansion or contraction with heat and cold, so the fit remains tightly sealed. Of course, the drawback on choosing gold as the metal for your crown is the lack of aesthetic appeal. In this case, you are choosing between having a gold tooth, or having a tooth that is natural in appearance. Therefore, many choose to have gold crowns placed only in less visible locations where a stronger tooth structure is more necessary (back molars).
Gold crowns are a good choice for many situations, but in some cases a porcelain tooth colored crown may be a better choice especially if the crown will be visible. Your Cumming Dentist can help you choose the best dental crown material for your situation.

There are a few different materials that crowns can be made out of, and the choice for your type of crown is based on a few different reasons. Crowns are always placed over teeth that have received root canals, and are also used to treat large areas of decay or fractured teeth.
Temporary crowns are always made of stainless steel. Sometimes called “silver caps”, these crowns are typically used on children whose oral anatomy is still developing. Stainless steel crowns are not made to last more than a few years, and will wear through over time if they are kept on longer than they should be. Most of the time these are used on baby teeth that will fall out within a few years, or on a developing permanent tooth that is not yet fully erupted.
Gold crowns are sometimes the material of choice for teeth in the back of the mouth, due to the benefits that gold has when it comes to it’s wear over time. Gold functions very well on grinding teeth and can be more comfortable to wear since the softer material is shaped easily to the way you bite together.
Porcelain crowns are the treatment of choice for teeth in the front of the mouth, or that show when you talk or smile. The material is carefully matched to adjacent natural tooth enamel so that it blends in as best as possible with the rest of your smile. Some crowns are completely made of resin while others are porcelain fused to metal. Depending on technology offered in your dental office, they may also be available for same-day placement thanks to 3D imaging technology and in-office lab equipment.
