Knowledge is the biggest defense against anxiety. Avoiding caffeine before a dentist can make you less anxious. Unlike sugary foods, eating high protein foods can have a sedative effect. During surgery, pay attention to regular and slow breathing. When you are nervous, you tend to hold your breath, which can reduce oxygen levels and further increase the sense of panic. Tell the dentist with a gesture when you are not feeling well. If you have a particular fear, consult your dentist. He or she can for a long time eliminate any negative or terrible images that you may have.
