What is Cold-Sensitive Tooth?
In Teethy a layer of enamel protects the crowns of your teeth—the part above the gum line. Under the gum line, a layer called cementum protects the tooth root. Underneath both the enamel and the cementum is dentin.
Dentin is less dense than enamel and cementum and contains microscopic tubules (small hollow tubes or canals). When dentin loses its protective covering of enamel or cementum these tubules allow heat and cold or acidic or sticky foods to reach the nerves and cells inside the tooth. Dentin may also be exposed when gums recede. The result can be hypersensitivity.
Symptoms Of Tooth Sensitivity To Cold:
- The main symptom of tooth sensitivity to cold is a discomfort or pain after eating or drinking something cold like ice cream, cold drink frozen food etc.
- Some people also feel pain while brushing or flossing.

Vigorously brushing your teeth with a hard-bristled toothbrush can gradually wear down tooth enamel. This is the outer layer of the tooth which protects the inner layer. Worn tooth enamel can gradually expose the dentin layer of your teeth, which is the second layer where the nerve endings are. Drinking or eating something cold could irritate the nerves and cause sharp, intermittent pain in the mouth.

Exposed Nerve Roots:
The biological reason behind teeth sensitivity to cold starts in the pulp of the tooth. The nerves in the pulp make teeth sensitive to cold when tooth roots become exposed due to receding gums or gum disease. Pathways called dentinal tubules are filled with fluid, and when a stimulus like cold air or cold liquid is applied to the exposed dentinal tubules, the fluid in the tubules moves and triggers a pain sensation in the nerve.

Tooth Decay or Gum Disease:
If your cold-sensitive teeth also hurt when you aren’t eating or drinking something cold, you could be in the early stages of tooth decay or gum disease. Plaque buildup on the teeth and gums can contribute to cold-sensitive teeth by eventually leading to tooth decay and gum disease.

Overzealous Product Use:
External factors that could cause cold-sensitive teeth to include brushing your teeth too hard, overusing tooth whitening treatments, or acids from everyday food and drinks, like wine, coffee, and tomatoes, that can cause irreversible loss of your tooth enamel.

Cold-sensitive teeth also can develop if excessive tooth grinding (bruxism) wears away the tooth enamel and exposes nerves. If you think that you are grinding your teeth, see your dental professional and ask about options for how to protect your teeth.

Cracks in Teeth:
Over time, tiny cracks can develop as your teeth expand and contract with exposure to hot and cold temperatures. The cracks provide another pathway to the nerves, making the teeth sensitive to cold. Check for lines that could indicate microscopic cracks.

If you notice persistent sensitivity to cold or heat in your teeth, give them a closer look. Check your gum line to see whether your gums are pulling away from your teeth. Receding gums can make it easier for feelings of hot and cold to travel to the nerves in your teeth.

Acidic foods like lemon, oranges, grapefruit, kiwi can also wear down tooth enamel and expose nerve endings that causes Cold-Sensitive Tooth.
