Often after giving the freezing people ask me what I just did, not knowing that I gave them the anesthetic. Modern dentistry has provided us with a few great tools that help me perform this "magic". We have long known that vibration will distract a nerve so that pain is not felt. Vibraject and DentaVibe are two products that implement this "trick". We have been using these for years now with great success. Another piece of equipment that helps is a computerized syringe (The Wand) which controls the fluid pressure. Pressure build up as the anesthetic enters (together with the acidity of the anesthetic) is what causes the sting. To reduce acidity we use a more nuetral anesthetic to start the freezing process. Once it is numbed a bit then the stronger more acidic anesthetics are used without even needing any further "tricks". Dentistry is no longer that difficult, so why risk having sedation or general anesthetic with all the negative effects on the body and potential hazards.
