Are your teeth tender? Does eating frozen yogurt make you feel pain? Here you have most common causes of tooth sensitivity.

You brush with too much force or your toothbrush is too hard: you can wear down the protective layers of your teeth and expose the microscopic hollow tubes or canals that lead to your dental nerves. When these tubules are exposed to hot or cold or to acidic or sticky foods, tooth sensitivity and discomfort can be the result.

Acidic foods: If the pathways to your nerves are exposed, acidic foods such as tomato sauce, lemon, grapefruit, kiwi, and pickles can cause pain.

You’re a tooth-grinder. Grinding your teeth can wear down the enamel, even though it’s the strongest substance in your body. By doing so, you expose the dentin, the middle layer of the tooth, which contains the hollow tubes that lead to your nerves.

You’ve got gum disease: Receding gums, which are increasingly common with age (especially if you haven't kept up with your dental health), can cause tooth sensitivity.

You have excessive plaque: The purpose of flossing and brushing is to remove plaque that forms after you eat. An excessive build-up of plaque can cause your enamel to wear away. Again, your teeth can become more sensitive as they lose their enamel protection.

Your tooth is cracked: A chipped or cracked tooth can cause pain that goes beyond tooth sensitivity.

There is decay around the edges of fillings: As you get older, fillings can weaken and fracture or leak around the edges. It’s easy for bacteria to accumulate in these tiny crevices, which causes acid build-up and enamel breakdown.
