There are a few different options for you to choose from when it comes to the material your crown is made of. In most cases, your dentist will give you the best recommendation based on where the tooth is in relation to your smile and its function in your mouth.
A porcelain ceramic material is popular with front teeth for cosmetic reasons. The porcelain can be matched to the surrounding teeth, giving you an even smile. This material can be more brittle than your natural teeth, so you may need to be mindful when biting off hard and crunchy foods.
Porcelain fused to metal is one alternative for a durable tooth that is still a part of your smile. With this type of crown, a cap of metal is fitted with a porcelain exterior that closely matches your natural teeth.
Base metal crowns are made from a mixture of non-noble metals. These crowns are very durable because they resist wear and fracture, making them a good choice for crowns placed on a molar. Since they are metallic, they are usually not suitable for replacing teeth in your smile.
Gold alloy crowns are actually a blend of gold and another metal, such as copper, to form a durable alloy. This material is a good choice for molars. This is especially true if you have problems with teeth grinding.
Your dentist can answer your questions and advise you on what type of material is best for your crown.
