Teeth that are sensitive to heat and cold are one of the most common dental complaints heard by most dental professionals, us included.

When consuming cold food or drinks, the liquid in the tubules moves and signals the nerve of your tooth to feel pain.
Acid erosion- The loss of tooth enamel due to acid exposure can cause cold sensitivity.
Bruxism/grinding- Grinding your teeth can cause them to appear flatter and shorter. This then, in turn, exposes the inner layer of the tooth called dentin and can lead to tooth sensitivity as well.
