Do Ceramic Crowns Turn Yellow?
Dental crowns are a common treatment used to restore a damaged tooth. Crowns can be used for various purposes, including covering cosmetic issues, protecting a tooth that is damaged tooth, and restoring the tooth’s function. It is possible for a crown to begin to show signs of discoloration, turn yellow, or wear over time. Below is a summary of various things that can cause damage to a crown and result in yellowing or discoloration. Depending on the cause, the issue may be able to be treated.
Staining and Discoloration
Ceramic and porcelain are materials that are commonly used to create a crown. When other types of materials are used, the crown can be more likely to have staining or discoloration. Because porcelain and ceramic are stain resistant, this is possible but less common. When the crown’s surface has tough stains, they often cannot be removed with routine brushing at home. Other causes of staining in crowns may include things such as smoking cigarettes, consuming highly acidic foods, and alcohol.
Professional Cleaning
In many cases, a professional cleaning can effectively remove difficult stains. Specialized tools allow the dental professional to clean the crown, eliminating these stains. The tools are designed to protect the crown from damage while restoring the crown’s white color. A professional cleaning can help remove yellow staining on a crown.
Teeth Whitening
When a patient completes teeth whitening, their crown may appear to be darker in color or have a yellow appearance. While the crown’s actual color did not actually change, the new color of the adjacent teeth can impact the crown’s appearance. Once the whitening treatment is complete, the color crown can differ from the natural teeth. Dental professionals often suggest patients undergo whitening treatment before the placement of a crown to prevent this from happening.
Discoloration and Damage
Damage to a crown can sometimes also impact the underlying natural tooth. A discolored or yellow crown can be due to an accumulation of debris or plaque. Unfortunately, this type of discoloration requires a professional cleaning as it cannot be reversed with regular brushing or flossing at home.
Crown Adjustments
In the event that there are adjustments made, it can damage the surface of the crown. Modifications are typically made prior to the placement of the crown. These adjustments ensure that it fits properly in the mouth. Adjustments also work to achieve the desired shape and size. It is possible for the adjustments to cause damage to the glaze or outer layer of the crown. It is also possible for the crown to be yellow when it is not glazed properly during the fabrication process.
Cleaning
While it is not common, it is possible for a professional cleaning to damage a crown when certain products or instruments are used. The crown’s glaze can be susceptible to damage.
Materials
When ceramic or porcelain are not used for a crown, the restoration can be at an increased risk for discoloration. It is important for patients to work with their dentist to determine what type of material will best meet their needs. The various materials used for crowns have specific benefits and challenges.
