Teeth sensitivity is a sudden, sharp, and shooting pain when teeth are exposed to extreme temperatures or sweet or spicy food. Teeth sensitivity happens when the dentin is exposed, a porous dental tissue due to loss of enamel or receding gums. Overzealous brushing, tooth grinding, dental cleaning or treatments, and gum diseases can contribute to teeth sensitivity. If you have any symptoms, visit our dental clinic in Edmonton for an appointment with our dentist.
