Many young adults are affected by tooth sensitivity stimulated by eating or drinking something hot, cold, sweet or acidic, which impacts their life quality.

The dentin contains a large number of parallel microtubules that run from the outside of the tooth to the nerve in the center. When it is exposed, these microtubules can be stimulated by changes in temperature or certain foods resulting in the sharp pain.
