When you feel a sensation while drinking hot or cold drink, or eating hot or cold food, you are facing dental sensitivity. This dental sensation is always painful or at least you experience an uncomfortable situation. There are many reasons which cause tooth sensitivity. Tooth sensitivity is a common problem and it has been estimated that approximately half the population experiences tooth sensitivity. Tooth sensitivity can come and go over time.



There may be different reasons which results in teeth sensitivity.

Brushing without care

Tooth sensitivity may be result of aggressive brushing or brushing with a hard-bristled tooth brush. This practice break down the protective layers of teeth and expose the microscopic hollow tubes or canals that lead to your dental nerves. When these tubules are exposed to hot, cold, acidic or sticky foods, tooth sensitivity and discomfort can be the result. The solution is to switch to a toothbrush with softer bristles and to be gentler when brushing.


Acidic foods and drinks

Acidic foods and drinks also erode the protective layer on teeth, such as lemon, pickles, tomato sauce, grapefruit, soda, soft drinks etc.



Some mouthwashes and rinses contain alcohol and other chemicals that can make your teeth more sensitive — especially if your dentin’s exposed. Solution to this problem is to use neutral fluoride rinses, and better is to quit the mouthwash and focus on flossing and brushing.


Excessive plaque

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. The solution is to practice good daily dental care and visit your dentist for cleanings every six months.


Gum disease

Receding gums can cause tooth sensitivity. If gum disease or gingivitis is the problem, your dentist may suggest a procedure to seal your teeth along with treating the gum disease itself.


Dental procedure

It’s common to have some sensitivity after a root canal, an extraction, or the placement of a crown. If your sensitivity doesn’t disappear after a short time, another visit to your dentist is in order.
