Tooth Sensitivity

Imagine this...after a hearty meal with family or friends, you are looking forward to a scoop of ice cream or a slice of chocolate cake or even just a hot cup of brewed coffee but as soon as any of those enter your mouth, your facial expression changes, you wince and hold on to your right or left cheek where you are experiencing a discomfort.  Why...even just a sip of cold water can trigger that discomfort! If these scenarios sound familiar to you, then you may be having sensitive teeth.

Did you ever wonder why you have sensitive teeth? There are various causes such as worn tooth enamel, exposed root portion of the tooth, tooth decay, gum disease, tooth fracture and tooth fillings that are worn down.

The enamel protects the crown of the tooth (portion that is above the gum line).  Beneath the gums is a thin layer called cementum which protects the root portion of the tooth. Beneath both the enamel and the cementum is dentin which is less dense and contains very, very small, hollow tubes called tubules.  When the dentin is exposed, it allows heat or cold or the acids to reach the nerve endings of the tooth through these tubules thus resulting is sensitivity.


The good news is that sensitive teeth can be treated and it will depend on what is causing the sensitivity. Ask  your dentist about it during your next appointment.
