Gotta get mine filled tomorrow. The novacaine shot(yeah big spelling error there) always feels like a small little pinch. Believe it or not...it really isn't too big of a deal. I was really scared the first time and had a really hard time relaxing. I was really tense which caused me to shake a lot. Some advice for not getting cavities...brush your teeth two to three times a day, use act flouride, FLOSS, and cutting back on the pop, drinking it with food, and sticking to the not so sugared to NO pop at all...really does help. This is coming from a teen too. Also, from a person with a fear of shots...it really isn't so bad, but your lip feels really fat afterward even though it really is not!
