Avoid Aggressive Brushing

Aggressive brushing can cause tooth sensitivity for two reasons. First, aggressive brushing can lead to gum recession, which exposes the root of the tooth. The root lacks enamel, which helps to protect the nerve of the tooth, so external stimuli such as cold water can cause sensitivity within the nerve. Secondly, aggressive brushing can wear away the enamel’s outer layers, which can also lead to tooth sensitivity. Ensure that you use either a super soft or soft manual toothbrush, or an electric toothbrush with a pressure indicator, to prevent brushing too hard.
