Pain sensitivity.

Pain sensitivity usually indicates tooth sensitivity or tooth decay problems. It usually manifests itself as an allergic reaction to hot, cold, sweet or sour foods or beverages. Tooth sensitivity is usually caused by eroded enamel, receding gums or exposed dentin or roots that protect the nerves of the teeth and trigger an inflammatory response to external stimuli. Typically, this sensitivity pain begins immediately upon contact with the stimulus and quickly disappears when the stimulus is removed. However, tooth decay can also cause sensitivity pain. Cavities are caused by bacteria that eat away at the tooth, making it sensitive to stimuli such as cold, heat, sweet, and acid. If cavities are not filled, they can become more painful and lead to more serious problems such as pulpitis. In order to identify and resolve any problems in a timely manner, it is vital that you seek medical attention as soon as you experience painful sensitivity.
