How Much Tooth is Needed for a Crown?

Posted by

When it comes to dental procedures, crowns are one of the most common. They are used to restore damaged or decayed teeth, and can also be used for cosmetic purposes. However, many people wonder how much tooth is needed for a crown. In this article, we will explore this question in depth.

What is a Crown?

A crown is a dental restoration that completely covers a damaged or decayed tooth. It is typically made of porcelain or ceramic, and is custom-made to fit the patient’s tooth. Crowns can also be made of metal, but these are less common due to their appearance.

Crowns are used to restore teeth that have been damaged by decay, trauma, or other factors. They can also be used to improve the appearance of teeth that are discolored or misshapen. Crowns are typically placed over the tooth after it has been prepared by the dentist.

How Much Tooth is Needed for a Crown?

The amount of tooth that is needed for a crown depends on several factors, including the extent of the damage or decay, the location of the tooth, and the type of crown being used. In general, the more tooth structure that is left, the better the prognosis for the tooth.

For a crown to be successful, there must be enough tooth structure remaining to support it. This means that the tooth must be strong enough to withstand the forces of chewing and biting. If there is not enough tooth structure remaining, the crown may not be able to stay in place, or it may fail over time.

In general, a minimum of 2mm of tooth structure is needed for a crown to be successful. However, this can vary depending on the location of the tooth and the type of crown being used. For example, a molar tooth may require more tooth structure than a front tooth, due to the forces of chewing and biting.

Types of Crowns

There are several types of crowns that can be used, each with its own advantages and disadvantages. The most common types of crowns include:

  • Porcelain or ceramic crowns
  • Metal crowns
  • Porcelain-fused-to-metal crowns
  • Zirconia crowns

Porcelain or ceramic crowns are the most common type of crown used for cosmetic purposes. They are made to match the color of the patient’s natural teeth, and are often used for front teeth. Metal crowns are typically used for back teeth, as they are stronger and can withstand the forces of chewing and biting. Porcelain-fused-to-metal crowns are a combination of porcelain and metal, and are often used for back teeth. Zirconia crowns are a newer type of crown that are made of a strong, durable material.

The Crown Procedure

The crown procedure typically involves two appointments. During the first appointment, the dentist will prepare the tooth by removing any decay or damage. They will then take an impression of the tooth, which will be used to create the crown. A temporary crown will be placed over the tooth to protect it until the permanent crown is ready.

During the second appointment, the temporary crown will be removed and the permanent crown will be placed over the tooth. The dentist will check the fit and make any necessary adjustments before cementing the crown in place.

Caring for a Crown

Caring for a crown is similar to caring for natural teeth. It is important to brush and floss regularly, and to avoid chewing on hard objects or using teeth as tools. Regular dental checkups are also important to ensure that the crown is functioning properly.

Conclusion

In conclusion, the amount of tooth that is needed for a crown depends on several factors, including the extent of the damage or decay, the location of the tooth, and the type of crown being used. In general, a minimum of 2mm of tooth structure is needed for a crown to be successful. If you are considering a crown, it is important to discuss your options with your dentist to determine the best course of treatment.
