Sensitivity has many shades of meaning but most relate to your response to your environment â either physical or emotional. Sensitivity to cold means youâre quick to notice the slightest chill â in the air or in another personâs actions. A sensitivity to pollen means youâre sneezing any time itâs in the air â you just always seem to react to it. Itâs the same with emotions â sensitivity means you pick up on the feelings of others.

Cavities can cause sensitive teeth and are treated with fillings. New dental work can be sensitive for a period of time as the nerve heals. Roots exposed from receding gums can be sensitive.
