Versatile dental crowns offer an excellent solution for damaged or fragile teeth. Your Orlando, FL, dentist, Dr. Marcia Martinez, helps her dental crownspatients maintain healthy smiles with dental crowns and a variety of other dental services and procedures.

What are crowns?

Dental crowns are hollow restorations designed to fit over the part of your tooth that's visible when you open your mouth. The restorations match your tooth color and can be constructed from porcelain, porcelain-fused-to-metal, ceramic, or resin. Crowns are cemented to your teeth and feel completely natural. In fact, you may soon forget that you even have a crown.

How can crowns help my teeth?

Crowns can be used to:

  • Prevent Fractures and Breaks in Fragile Teeth: Cracks or tooth trauma can weaken teeth, but they can also become fragile due to certain dental procedures, such as root canals, or even aging in some cases. Adding a crown stabilizes the tooth and prevents it from breaking. Every time you eat, you generate strong biting forces that could fracture an at-risk tooth. These forces are absorbed over the surface of your crown, protecting the tooth underneath.
  • Restore Broken Teeth: Broken teeth are certainly unsightly, but their appearance is not the only issue. Chewing can become difficult when teeth are broken. The teeth can also be quite painful if the broken ends are exposed to the air. Crowns restore the appearance of broken teeth, end your pain and improve chewing and biting.
  • Improve Appearance: Crowns also offer cosmetic benefits and can change the shape and length of teeth or hide discolorations.

What happens when I receive a crown?

During your first crown appointment, your tooth must be prepared to accommodate the crown. Your Orlando, FL, dentist will also make an impression of your mouth that will be sent to a dental laboratory. While you wait for the technicians to create your permanent crown, you'll be fitted with a temporary restoration. Although you can eat almost anything with the temporary crown, you'll need to avoid eating hard or sticky foods.

In about two weeks, you'll return to the dentist's office. After Dr. Martinez checks the fit of your new crown, she'll make a few adjustments before cementing it to your tooth.

A “crown” or a “cap” is the term used to restore a decayed or broken tooth that needs to be completely encased to protect the tooth beneath it. A crown's dual purpose is to restore the tooth's form and function. Decades ago gold was the material of choice for a crown. What we ultimately choose depends on a particular crown's requirements with regard to the tooth's appearance and function, and to some extent what you want.

Gold: Gold crowns last the longest and wear the best (at about the same rate as natural teeth), but they are not used as frequently today, especially if they are visible in a person's smile. Gold crowns are made of cast gold, a technique that has been in use for over a hundred years. They can last for decades, and have been known to last 50 years or more. They tend to cost less per tooth than porcelain or other materials.

All-Porcelain: “All porcelain” crowns have a natural appearance and as technology improves they are gaining popularity. Dental porcelains are composed of ceramic substances that are variations of glass. This gives them their translucent, lifelike appearance — but it makes them brittle and subject to fracture. Therefore all-porcelain crowns may not be a good choice for back teeth because they frequently fail under the biting forces applied during chewing and especially adverse habits like tooth clenching or grinding. Porcelain crowns are made of material that doesn't wear. Consequently, it can cause excessive wear to the teeth they bite against.

Porcelain-Fused-to-Metal (PFM): PFM crowns have been in use for more than 40 years. They combine a substructure of gold or platinum for strength and have porcelain “facings” for the visible surfaces. In some ways they combine the best of both worlds, but they do have some problems; the metal can show through the porcelain, detracting from its life-like appearance. These crowns can have a functional lifespan of about 20 years or more.

New and Future Materials: Newer “pressed-ceramic” restorations and computer-milled ceramics have received good reviews for aesthetics and service. These new materials are being intensively researched. Initial results look good, but we'll have to see how they last over time.
