When Is a Kids Dental Crown Needed After Cavity Treatment?

Kids dental crowns can treat many dental issues, including cavities that are too large for traditional filling material. Cavities can eat away and weaken children's teeth, requiring restorative treatments to protect the teeth's structure and function. Here are the details about when dental crowns can help after a cavity treatment.

When there is a need to replace a large, damaged, or worn-out dental filling

A pediatric dentist may suggest a kids dental crown if a child has a large filling that occupies most of the tooth's surface. In some cases, a previously placed filling may become damaged or worn out, requiring a more durable restoration. Crowns provide full coverage for the affected tooth, offering better protection than conventional fillings. Their durability helps prevent future fractures and reduces the risk of reinfection.

Large fillings can weaken the remaining natural tooth structure, making the tooth more susceptible to cracks or breaks. In such cases, the pediatric dentist carefully removes decayed enamel and prepares the affected tooth. The pre- or custom-made crown is then securely cemented to the treated tooth to restore strength and function.

When there is a need to protect the teeth after a root canal therapy

Severe tooth decay can allow bacteria to penetrate the enamel and reach the inner pulp chamber, where the nerves and blood vessels reside. When this occurs, a baby root canal — also known as a pulpotomy — becomes necessary to remove the infected pulp. Then, the dentist will replace the material with a biocompatible material, such as gutta-percha.

After the root canal, the dentist may recommend placing a kids dental crown over the treated tooth. This type of restoration can protect the tooth from future damage and infection while strengthening it. Dental crowns help ensure the child can comfortably eat and chew while maintaining the remaining natural dental structure.

Placing the dental crown

During the consultation, the pediatric dentist will discuss the most suitable crown materials for the child. Common options include stainless steel and ceramic crowns. Factors such as durability, aesthetics, and the location of the tooth will help determine the best option. The type of material will also depend on whether the dentist is placing the crown on a primary or permanent tooth.

The pediatric dentist often takes dental X-rays to assess the extent of decay and determine if additional treatments, such as a pulpotomy or root canal therapy, are necessary. If necessary, the dentist will remove decayed areas and shape the tooth to accommodate the crown. Then, they will take an impression of the treated tooth to ensure the crown will be comfortable and functional.

The dentist may place a temporary crown over the treated tooth to protect it while an off-site dental lab makes the custom-made crown. Once it is ready, the pediatric dentist will make adjustments to the crown and ensure it fits comfortably before cementing it into place.
