You would think with everything I have been through I would not be so afraid of the dentist. I am though. My dentist is very understanding and gives me nitrous before doing anything other than a cleaning. You are conscious with nitrous but it just sort of relaxes you, makes you feel like you are floating. Last time I had a cavity filled I was actually disappointed that he did it so fast. I was actually enjoying my little nitrous vacation. We have to find joy where we can!
