What is one of the primary functions of an adhesive in a dental restoration?

One of the primary functions of an adhesive in a dental restoration is to minimize leakage and seal the cavity. This is crucial in ensuring that the restorative material securely bonds to the tooth structure, creating a tight seal that prevents bacteria and food particles from entering the space between the tooth and the restoration. A well-sealed restoration is essential for the longevity of the dental work, as it helps to protect the underlying tooth from decay and other complications.

By effectively minimizing leakage, the adhesive contributes to the overall health of the tooth and enhances the durability of the restoration. This sealing function is particularly important because any gaps or misalignments can lead to further dental issues, such as secondary caries or sensitivity, ultimately compromising the success of the dental procedure. Additionally, a successful adhesion helps in distributing occlusal forces evenly during chewing, ensuring patient comfort and the integrity of the restoration.
