Indication for Full Coverage Crowns

Dental crowns have become an increasingly popular treatment for restoring and treating various issues. Crowns are a reliable solution which offer quality results. The prosthetic restores the outer layer of the tooth, serving as the tooth’s enamel. It also protects the internal layers including the dentin and pulp. A crown can help prevent pain, sensitivity, and additional damage to the tooth.

Another benefit of a dental crown is the ability to restore the tooth’s function. This is especially common following dental work such as a root canal, large filling, and replacement of a missing tooth. The crown is effective in providing a protective cover and strong chewing surface.

Dental crowns are also commonly used for cosmetic reasons. They are effective in concealing discoloration, fillings, and broken or damaged teeth.

The indications for dental crowns include root canals, large fillings or cavities, dental implants, tooth replacement, restoring cosmetic flaws, cracked teeth, and crown replacements.

Crown Following a Root Canal

A root canal is a treatment used to preserve the teeth by eliminating bacteria from an infected tooth. It also protects the tooth from further infection. Infection can cause the pulp to become inflamed. A root canal may also be recommended to preserve a tooth which experienced trauma and resulted in exposure of the pulp.

Root canals are an effective method for preserving the natural tooth, however, the tooth structure is often weakened. The dental professional will typically drill through the tooth to access the pulp. The inside of the tooth is then cleaned, and a filling is applied. Any decayed enamel or dentin is removed to prevent further damage. Following treatment, the tooth is not strong enough to endure the extreme forces of chewing.

Placing a crown on a tooth after a root canal treatment can restore the function and prevent additional damage. A crown is not always required following root canal treatment. Teeth that experience lower chewing forces and have adequate structure will not require crowns.


One of the most common indications for a dental crown is replacing an old crown. Crowns last an average of 10-15 years. There are various factors, however, which can impact the longevity of a dental crown.

If a patient has periodontal disease surrounding a dental crown, the crown will certainly require replacement. Inflammation typically occurs where the crown and gum meet.

In addition to gum disease, dental caries are another common indicator for replacement of a crown. When there are dental caries on an adjacent tooth, the crowned tooth can quickly be affected. The dentist must remove the crown, treat the decay on the natural tooth, and place the new crown.

Another common cause for the replacement of a crown is when it is damaged and cracks appear on the crown. Materials like porcelain are commonly used to create a crown. Porcelain is quite brittle, making cracks relatively common.

When a crown cracks, the natural tooth is exposed to infection. Teeth with a crown may also be more sensitive to cold and hot temperatures.

In some cases, crown replacement can restore an aesthetic concern. Over time, the teeth naturally change in color and can be discolored. As a result, the crown may stand out more and differ in its color from the natural teeth. Crowns may appear to be whiter or opaque when compared to the adjacent natural teeth.

Patients who are considering a crown for any reason should follow up with their dentist. The dentist can discuss any questions and help determine if the patient is a good candidate for a crown or crown replacement.
