My friend had not seen a dentist very a long time because she was scared of the dentist. She became very anxious just thinking about it, and whenever she did go, always had her husband come along with her.
Everybody reacts differently to the dentist, and they have several ways to help you stay calm. Many dentists have the opportunity to listen to music, and nitrous oxide is always an option if you really need it.
I always like to listen to music because it helps drown out all of the noise around me. I hate hearing the sound of the drills and do better if it isn't so loud.
