What should be done if a sealed tooth develops sensitivity?

When a sealed tooth develops sensitivity, it is important to evaluate for potential underlying issues and recommend appropriate treatment. This is because sensitivity can indicate problems such as decay beneath the sealant, improper sealing technique, or even issues related to the tooth structure itself, such as cracks or fractures. Ignoring the sensitivity could lead to a more serious condition, including progression of dental disease or pain, which might ultimately require more invasive treatment.

Assessing for underlying issues ensures that any potential problems are addressed promptly, as the presence of sensitivity often signifies that the sealant may not be functioning effectively or that the tooth may need further care. Furthermore, recommending appropriate treatment based on the evaluation can help to alleviate discomfort and restore the health of the tooth.

Other options fail to provide a comprehensive or proactive approach to addressing the sensitivity. Ignoring it does not support proper dental health practices, applying additional sealant without further evaluation could exacerbate the problem, and merely checking for trapped food does not address the underlying causes that may be present. Therefore, a thorough evaluation leading to tailored treatment is the best course of action.
