Local Anesthesia…A lot of people don’t like dental work because they believe it will be painful or uncomfortable. There’s an anatomical reason to back up that concern — the mouth with its dense network of nerves in the teeth and gums is one of the most sensitive parts of the human body. But modern dentistry has helped solve much of the problem of pain with advances in local anesthesia. Using substances that temporarily block electrical impulses within the nerves of a selected area of oral tissues, there’s a good chance you’ll feel little to no discomfort even during moderately invasive procedures. Unfortunately, you might have heard some complaints from others about local anesthesia that might make you wary of it. Many of these complaints, however, aren’t fully based on all the facts. So, let’s set the record straight about local anesthesia and what you can expect. No need to be afraid of needles. Nobody enjoys the painful prick from an injection needle, and some people are highly fearful of them. But although it’s necessary to use a needle to deliver anesthesia to deeper levels of tissue, it’s possible you won’t feel it. That’s because we’ll typically apply a topical numbing agent to the skin surface that deadens the top layers where we insert the needle. That numb feeling afterward won’t last long. One of the chief complaints in the past about local anesthesia was the irritating numbness that could long linger after a procedure. Today, however, with more advanced anesthetics and formulae, we’re better able to gauge the duration of the medication’s effect. This has greatly reduced the length of time afterward your mouth might have that awkward numbing sensation. Anesthesia isn’t necessary for every procedure. Unless you have hypersensitive teeth, a lot of dental procedures don’t require anesthesia. Your enamel, for example, has no nerves and actually serves as a kind of “muffler” for sensations to lessen their effect. Cleaning your teeth or removing portions of the enamel can normally be performed without the need for numbing medication. For procedures, though, where pain could be a factor, local anesthesia can make all the difference in the world. In these cases, anesthesia is your friend — it can help you receive the dental care you need without the discomfort.
