Treatment Through a Crown
What If I Already Have a Crown?

Absolutely - yes. Many patients wonder: “I have a crown. Can you still perform a root canal treatment through the crown?” The answer is usually yes. In most cases, the root canal treatment can be carried out through a small opening in the existing crown, without needing to remove or replace it.

During the treatment, we create a precise opening in the crown, just large enough to access the underlying tooth and the root canals. After the treatment, this opening is securely sealed with a filling material. This allows the crown to remain functional and aesthetically pleasing.

Although most crowns can stay in place, there are cases where: the crown is already leaking or damaged, decay has developed underneath the crown, or the crown does not provide a proper fit anymore. In those situations, replacing the crown may be advised to ensure a long-lasting, healthy result. We will always discuss this with you beforehand so you know exactly what to expect.

Usually, treating a tooth through the crown does not add significant cost. Replacement of a crown is only recommended if clinically necessary. As with all treatments, costs follow the official NZa tariffs, which vary each year and can be found on the website of the Dutch Healthcare Authority (NZa).

A crown strengthens the outside of a tooth, but it does not protect the inside. If the nerve becomes inflamed or infected, a root canal treatment is still needed to relieve symptoms and save the tooth.
