主题：Why are people afraid of going to the dentist?

Mouth is a very personal part of our body. Lying in the chair and having a dentist working with drills centimeters away from our nerves can make us feel very vulnerable. If you have previous bad experience with a dentist, then you are even more likely to avoid going to one if possible.

Dentist：牙医
Drill：电钻
Nerve：神经
Vulnerable：脆弱的
