Answer the question about text:

The heavy - handed manly woman who was my dentist has left and now I ' m in the hands of a very pleasant 26 year - old boy who has a much gentler touch . I ' m not sure what he must make of me though . After having half my face numbed he invited me to " please rinse " . I followed his instructions and then spat all the mouthwash over the floor - I had no control over my mouth at all .

What is the reason a pleasant 26 year - old boy who has a much gentler touch has replaced the heavy handed woman ?
He is an intern at the dentist I go to .
