Dental Crowns

Overview

What Are Dental Crowns?

A dental crown is a custom-made cap that fits over an entire tooth, restoring its shape, size, strength, and appearance. Crowns are used when a tooth is too damaged, decayed, or weakened to be repaired with a simple filling. They fully encase the visible portion of the tooth above the gum line, providing 360-degree protection and support. Dental crowns are also used to cover dental implants, anchor dental bridges, protect teeth after root canal treatment, and improve the appearance of severely discolored or misshapen teeth. Modern crowns are crafted from advanced materials that closely replicate the look and feel of natural teeth.

Materials

Types of Dental Crowns: E-Max and Zirconium

The two most popular types of dental crowns used in modern cosmetic dentistry are E-Max and Zirconium. E-Max crowns are made from lithium disilicate ceramic, offering exceptional translucency and the most natural-looking appearance, making them the preferred choice for front teeth. Zirconium crowns are crafted from zirconium dioxide, an incredibly strong and durable material that is ideal for back teeth where biting forces are greatest. Both materials are metal-free, biocompatible, and resistant to chipping and cracking. Your dentist will recommend the best material based on the location of the tooth, your bite pattern, and your aesthetic preferences.

The Process

The Crown Procedure

The dental crown procedure typically requires two visits over 5 to 7 days. During the first appointment, your dentist will examine the tooth, take X-rays, and prepare it by reshaping it to accommodate the crown. A precise digital or physical impression is then taken and sent to the dental laboratory. A temporary crown is placed to protect the prepared tooth while your permanent crown is being fabricated. At the second appointment, the temporary crown is removed, and the permanent crown is checked for fit, color, and bite alignment before being permanently cemented in place. The result is a strong, natural-looking restoration that blends seamlessly with your surrounding teeth.

Benefits & Features

Full Coverage Protection

Dental crowns completely encase the visible portion of the tooth, providing comprehensive protection against further damage, decay, and fracture.

Natural Appearance

Modern crown materials like E-Max and Zirconium closely mimic the color, translucency, and texture of natural teeth, making them virtually indistinguishable.

Exceptional Durability

High-quality dental crowns are built to withstand the daily forces of chewing and biting, with a lifespan of 15 to 25 years depending on the material used.

Restores Full Function

Crowns restore damaged teeth to their original strength and function, allowing you to eat, speak, and smile with complete confidence.

Biocompatible Materials

Both E-Max and Zirconium are metal-free and biocompatible, meaning they are safe for the body and will not cause allergic reactions or gum discoloration.

Frequently Asked Questions

With proper care, dental crowns typically last between 15 and 25 years. E-Max crowns generally last 15 to 20 years, while Zirconium crowns can last 20 years or more due to their exceptional strength. Regular dental check-ups, good oral hygiene, and avoiding habits like teeth grinding will help maximize their lifespan.

The procedure is performed under local anesthesia, so you will not feel pain during the tooth preparation. Some patients may experience mild sensitivity or discomfort for a few days after the procedure, particularly when the temporary crown is in place. This is normal and typically resolves once the permanent crown is fitted.

E-Max crowns are made from lithium disilicate ceramic and offer superior aesthetics with a natural translucency that is ideal for front teeth. Zirconium crowns are made from zirconium dioxide and provide exceptional strength, making them better suited for back teeth. Your dentist will help you choose the right material based on the tooth location and your individual needs.

While uncommon, a crown can occasionally become loose or fall off due to cement failure, tooth decay underneath, or excessive force. If this happens, keep the crown safe and contact your dentist as soon as possible. In most cases, the crown can be recemented or a new one can be fabricated.

Care for crowned teeth the same way you care for your natural teeth. Brush twice daily, floss carefully around the crown margins, and use an antibacterial mouthwash. Avoid chewing ice, hard candy, or other very hard objects. If you grind your teeth at night, ask your dentist about a custom night guard to protect your crowns.
