Final answer:
Dentinal hypersensitivity resulting from instrumentation is usually mild and resolves within a few weeks.
Step-by-step explanation:
Dentinal hypersensitivity refers to a condition where the dentin, the sensitive layer of the tooth, becomes exposed and causes pain or discomfort in response to stimuli such as hot, cold, or sweet. Instrumentation, such as dental procedures like scaling and root planing, can sometimes cause temporary sensitivity. In most cases, this sensitivity is mild and resolves within a few weeks as the tooth and surrounding tissues heal. However, if the sensitivity persists or worsens, it is important to consult a dentist for further evaluation and treatment.
