Reaction to dental anesthetics?
by Rosy G
Reply by Shelly ~ admin Hi Rosy It's hard to know for sure without more details but it could be a reaction to the epinepherine that is found in most dental anesthetics. An increased heart rate is not unusual if you are sensitive to epinepherine. Some other reactions include shaking, feeling lightheaded, or tingling in your fingers and toes. This reaction usually goes away quickly, but can be annoying and worrisome especially if you are already a little bit nervous about your dental treatment:) One reason dental anesthetics contain epinepherine is to make the anesthetic last longer. Without it, the numbness can wear off in just a few minutes. Epinepherine constricts your blood vessels and slows the metabolization of the anesthetic. An added benefit for dental surgeries...there is less bleeding if epinepherine is used. Sometimes, (but not often) the anesthetic gets injected directly into your bloodstream and you feel an adrenaline "rush". This has happened to me once or twice while getting dental treatment. Sometimes I feel cold and shivery too. But I still prefer to have anesthetic with epinepherine because it doesn't wear off too soon. If you get a shaky shivery feeling at your dental appointment, ask for a blanket. Most dentists keep a cozy blanket on hand for patients who need it. Here are some other ways to help you relax and make your dental visit more comfortable. If you have this reaction every time, ask for anesthetic without epinepherine. I hope this helps, ~Shelly~ |
