We all know how positive thinking can make the difference in a situation. In a study where students were asked to spend 5 minutes imagining themselves as a college professor before an exam their marks were significantly higher. Conversely a group that were reminded of some detriment in their life ended up doing significantly worse. So what do you think about before your dental exam/visit?
Many other studies show how priming and conditioning and positive imagery makes differences in our lives. Self hypnosis has actually been used to do surgery on patients without any anesthesia. Just remember though to use positive phrases. Your body and mind don't hear adjectives and adverbs very well. So say "I am okay with this" not "I am not going to be afraid".
