Resin Crowns: Q & A

If you have recently undergone a restorative procedure for one of your teeth, such as a dental filling or a root canal, your dentist may place a dental crown over the treated tooth. Dental crowns are used to cover, protect and restore the functionality to a tooth.

There are multiple types of crown materials, such as porcelain, porcelain-over-metal, stainless steel and resin. However, the least expensive type of dental crown is usually the resin crown. Here are a few questions and answers about resin crowns:

Are resin crowns suitable for all teeth?

Resin crowns are usually used for front teeth. Since the crowns are made of plastic material, they may wear away more easily if placed on back teeth that are responsible for grinding your food.

What are resin crowns made of?

Originally, resin crowns were made of rubber. However, over time, other types of resins have been designed for use in dentistry. Currently, acrylic polymer resins are often used for dental crowns. Some resins such as polymethyl  methacrylate are actually mixtures of monomers and polymers that react when combined, so they harden without the need for additional light or heat.

Is resin easily noticed on your teeth?

Resin crowns are difficult to discern on your teeth. They can be dyed to perfectly match the shade of your natural teeth.

How many visits are needed to permanently place a resin crown?

Most resin crowns can be fitted and placed in two dental visits. The first visit may be used to treat your damaged tooth and prepare a dental impression. There should be no decay remaining on the tooth that will be covered by the crown. After your tooth has been treated, a mold is prepared.  Your dentist will place a temporary crown over your restored tooth to protect it until your second visit.

During the time between your first and second dental appointments, your permanent resin crown will be prepared in a dental laboratory. The crown is permanently placed during your second visit.

If your dentist is planning to use a crown to cover one of your treated teeth, he or she may recommend a resin crown. Still, other crown options may be suitable depending on your particular dental needs. If you have questions about the type of crown that will be used to complete your dental restoration, schedule a consultation with your dentist to discuss your options. He or she can provide details to answer your concerns.
