Is tooth sensitivity that persists for the third day after an annual scaling treatment necessary?

I am an office worker who takes care of my dental health by receiving regular scaling every year without fail.

I usually make sure to get regular dental checkups, so I proceeded with a scaling procedure with a light heart. However, the tooth sensitivity that started immediately after the procedure has persisted for three days now, so I am posting this question out of concern.

In particular, I experience a strong sensitivity bordering on sharp pain whenever I drink cold water or eat cold food, which causes some discomfort in my daily life. Although I was told that temporary sensitivity is usually possible after scaling, I have been receiving consistent care every year. Therefore, seeing the symptoms persist for several days like this makes me concerned that the enamel on the tooth surface may be damaged or that the tooth roots may be excessively exposed due to gum recession.

I am wondering if tooth sensitivity persisting for more than 3 days after a procedure is part of the normal recovery process, despite having a healthy oral condition and receiving regular scaling.

In addition, I would like to hear the expert opinions on whether using toothpaste specifically designed for sensitive teeth would help alleviate these symptoms, or if I need to visit the clinic again for additional treatment, such as desensitization therapy. I would also appreciate it if you could let me know the maximum duration of these symptoms typically considered within the normal range.
