One way of coping with dental anxiety is by distraction.
When you are nervous it may seem impossible to distract yourself from your dental exam. Yet there are some things that that can do to help distract your thoughts.
Such as: Wear headphones. If the sound of the drill bothers you, bring headphones so you can listen to your favorite music or audio-book. Some dental offices even have televisions or show DVDs. Just make sure to work out hand signals to your dentist if you need to have a brake or to let her or him know about any issues.
Occupy your hands by squeezing a stress ball or playing with a small handheld object. Imagine your happy place and visualize yourself at a relaxing beach or garden.
