What is a possible post-operative complication of non-surgical periodontal therapy?

Dentin hypersensitivity can occur as a post-operative complication of non-surgical periodontal therapy due to the exposure of dentinal tubules during procedures such as scaling and root planing. This exposure can lead to discomfort or pain in response to various stimuli, such as temperature changes or mechanical pressure. The removal of subgingival tartar and biofilm may inadvertently expose sensitive areas of the tooth root that were previously protected by calculus, resulting in sensitivity.

While patients may experience other issues post-therapy — such as gingival hyperplasia, which is more commonly associated with certain medications rather than periodontal procedures, or increased plaque accumulation resulting from changes in oral hygiene habits post-treatment — dentin hypersensitivity is the most directly related complication of non-surgical interventions aimed at reducing periodontal disease. Crown fractures are typically a result of trauma or excessive occlusal force rather than periodontal therapy itself.
