Block injection

A block injection is used to suppress nerve activity in an area of the mouth; this is usually around the lower jaw. Most commonly block injections are forms of local anaesthesia and are injected to numb a small area surrounding an infected or problematic tooth in order to stop the sensation of pain. There are several types of local anaesthetic and some people may suffer from allergies to some substances; it is therefore important to talk through your individual needs and concerns with a dentist prior to being injected with local anaesthetic. The feeling of numbness is often very unpleasant as people feel they lose control of their mouth and are unable to swallow thus causing them to panic about choking; although it is true that the sensation is not nice, there are no dangers related to choking associated with blocking procedures.

Side Effects of Block Injections

There are side-effects associated with nerve blocking agents, although these are fairly uncommon; they include retention of fluids and a loss of appetite caused by taking steroids and possible nausea, sickness and constipation brought about by taking morphine or products containing morphine.
