What can help alleviate sensitivity in patients with exposed dentin?

Desensitizing agents are specifically designed to help alleviate sensitivity in patients with exposed dentin. When dentin is exposed, the tubules within it become accessible to external stimuli, leading to discomfort or pain. Desensitizing agents often contain compounds like potassium nitrate or fluoride, which work by occluding these tubules and reducing the transmission of sensations to the nerve endings within the tooth. They can effectively decrease sensitivity over time, providing relief for patients experiencing discomfort.

Other approaches, such as cavity treatments or modifying brushing techniques, may address the underlying issues or further protect teeth but do not directly target sensitivity in the same manner as desensitizing agents. Cold drinks, in fact, could exacerbate the discomfort rather than alleviate it, as cold temperatures can stimulate the exposed dentin, prompting pain responses.
