Dental crowns for premolars and molars are usually not for aesthetic purposes but due to root canal treatment where the tooth becomes fragile and requires a crown for chewing functions. Therefore, when choosing dental crowns for the back teeth patients choose more cost effective dental crown materials.
Regardless of front teeth or back teeth there is a range of dental crown materials which include metals, precious metals and porcelain. There is a range of dental crowns to choose from.
1. Porcelain Fused to Cobalt-Chromium Crown
This type of dental crown is currently the cheapest and the interior of the crown is made of cobalt-chromium whereas the exterior is porcelain. This type of crown is durable and susceptible to decay and is most cost effective.
2. Porcelain Fused to Titanium Crown
The interior of this type of crown is pure titanium with a porcelain exterior. Porcelain fused to titanium crowns are the best choice to prevent allergic reactions. However, the porcelain can chip or break.
3. Porcelain Fused to Gold Crown
Porcelain fused to gold crowns is where the interior is made of gold and the exterior is porcelain. This type of crown is better for aesthetics compared to porcelain fused to metal crowns.
4. Zirconia Crowns
Zirconia crowns are the most durable type of dental crowns available and is even more durable than metals. When used for the back teeth there is no problem and is a great option for patients with allergies to metals. Chipping is also less like to happen to the durability of the material.
The advice of your dentist is important. Whether you choose to repair with the use of a crown or a dental bridge the dentist will provide a treatment plan and options. Patients will have to avoid overly hard foods once the crown is fitted. Though crowns are durable there is still the need to make changes as a dental crown can match the functions of natural teeth.
