It Is Caused by Exposed Dentine!
Tooth sensitivity is when pain occurs caused by external stimuli or the enamel that protects our teeth gets thinner or gum recession occurs. It mainly comes from two dental structures and first affecting is the crown.
Enamel Protects Your Teeth
Due to a cavity, the hard enamel that protects the tooth is eroded causing dentin to be exposed. External stimuli pass directly through tiny channels and affect the nerves. As the dentin is exposed, protection to teeth is greatly reduced. The dental structure underneath the enamel is filled with tiny channels. The size of these channels is heredity but can be affected by eating habits and saliva composition. External stimuli such as eating and cleaning teeth trigger the nerve endings in these channels and cause pain.

Tooth Sensitivity Is Also Known as Dentin Hypersensitivity
It is a symptom of a dental condition or a sign of a dental disease. Sensitive teeth symptoms include tooth pain when you eat cold, hot, sweet and acidic foods. Your teeth ache when you brush or floss, but the soreness is not persistent. If you have a cavity or a broken tooth, you may feel pain after eating cold food. However, if you do not suffer from a dental disease but still feel pain after eating cold food then you may have sensitive teeth.
In general, if the exposed tooth surface is kept clean, improper brushing such as inappropriate brushing force, brushing teeth immediately after eating acidic foods can cause teeth to erode. These sensitivities create a self-induced level of protection in the pulp and the situation will gradually be under control.
In addition, periodontal disease causes the root structure to slowly dissipate, gums around teeth start to shrink and roots are exposed, causing sensitivity; gums in older people also shrink slightly because there is no enamel protection around roots. Once the roots are exposed, teeth sensitivity occurs. Many people who brush their teeth encounter sensitive areas and would avoid brushing the sore spots. However, this increases the chance of tooth decay and gum inflammation due to improper oral care.
