WHAT? YOU JUST GAVE ME A SHOT? I BARELY FELT ANYTHING DOC! We use a new buffering pen that buffers the acid in anesthetic carpules which is added as a preservative. It takes the sting out of the injection by changing the acidic anesthetic to the neutral pH of the body. Shown on the left – The Onset Buffering Pen™. The Dental Vibe™ – This device vibrates to trick your brain into thinking you are getting a massage. When used with a custom compounded topical anesthetic called “Tricaine Blue”, most people barely notice the dreaded local anesthetic. Nitrous Oxide sedation is also available for a fee of $30.
