This could be related to nerve damage for example. Sometimes an impacted tooth in the lower jaw can be related to the nerve, which runs in a canal in the lower jaw. While all the precautions may be taken, the nerve may be damaged during the removal of the impacted tooth. This can result in some numbness, pain, bruising or tingling of the lower teeth, gum tissue, chin, and lip on that side. In most cases feeling will return to those areas within a few months as the nerve repairs itself. In some cases however, the nerve damage may be permanent with no recovery of sensation in the involved areas. Also, the nerve which gives feeling and taste to the side of the tongue may be damaged during the extraction of the impacted tooth and result in numbness, pain, burning, tingling, and loss of taste on that side of the tongue. This again may be temporary lasting only months but may also be permanent.
