The Needle and the Damage Done...

For many people, the fear of receiving a dental injection is enough to keep them away from seeing a dentist, even when they are fully aware that it is a necessity for good health. If you are one of those patients, know that you are not alone. It is estimated that at least 10% of adults have this fear, called Trypanophobia or commonly, needle phobia. Some phobics are afraid of dental injections in particular and some are afraid of all “shots”, avoiding any dental or medical care that involves injections and/or needles, like vaccinations, blood tests, etc. But do note that there are options for needle phobic people to get the health care they need.

     The use of a topical anesthetic prior to injection is very helpful. This numbs the surface of the skin so that the penetration of the needle is not felt. It needs to be on the surface of the tissue for at least a minute or two to have the full effect. For extremely phobic people, there is available a strong topical anesthetic that penetrates deeper into tissue. This type of topical anesthetic, called EMLA, can be used in extremely sensitive areas or on extremely sensitive people. It is not always used in dentistry because it tastes bad, compared to the flavored topical agents that work fine for most people.


Using nitrous oxide (commonly called laughing gas) for relaxation helps many phobics get beyond their fear. This is safe for all ages; the only major contraindication to receiving nitrous oxide is for pregnant women. It induces a calming, relaxing effect that allows the patient to remain fully awake, but with a great reduction in anxiety. Patients who use nitrous oxide report feeling warm and tingly and a general sense of euphoria. They are fully aware of what’s going on around them and are able to get treatment without their fear standing in the way.


Some people find it easier to receive an injection if they keep their eyes closed. Dentists will often talk while giving an injection to keep the patient’s mind distracted. Injections given too fast tend to be more painful, so the slower the injection, the less it will be felt. This runs counter intuitive to most phobic’s fears, because they want it done as quickly as possible. So if you find yourself wondering why it takes so long to give an injection, be aware that it is for increased comfort. Some patients find that wearing head phones with music or an audiobook playing helps keep them distracted. Dentists can usually work around whatever it takes to relax the patient and allow them to receive treatment. The main goal is for the patient to receive the health care they need with a minimal amount of stress and discomfort.
