Usually the upper wisdom teeth like your case are fairly straight forward with minimal trauma. 1. The bone around it is thinner and less dense. 2. Many times the root anatomy as indicated on your x-ray are more fused and less flared (less anchored) due to the lack of space. 3. The tooth is unopposed (no bottom tooth to subject forces which hardens the bone) which allows the tooth socket and bone to be less resistant to surgical forces. Best case scenario, the tooth will roll out gently in 5 to 10 seconds.
However, I encounter many dentists who are afraid to touch extractions so hopefully your dentist feels confident with this.
