One of the most common dental issues faced by people is tooth sensitivity. When eating certain kinds of food or food items at various temperatures, causes pain or discomfort in the tooth, the condition is known as tooth sensitivity.

When common teeth-related issues like enamel wear and receding gums remained untreated, it might result in Dentinal hypersensitivity. People within the age bracket of 20-50 years are more prone to tooth sensitivity.

Generally, the pain associated with tooth sensitivity is sudden, sharp, and temporary. In severe cases, the pain even reaches the root level of the tooth. Well, the good news is tooth sensitivity is very much treatable.

  1. Triggers Of Tooth Sensitivity:

  • Eating cold food or drinking cold drinks
  • Eating hot food or drinking hot drinks
  • Brushing teeth
  • Inhaling cold air
  • Eating sugary or sour foods
  1. Symptoms Of Tooth Sensitivity:

Individuals suffering from tooth sensitivity may show the following symptoms

  • The occurrence of spontaneous pain in the tooth without any apparent cause.
  • Sensitivity is restricted to one tooth.
  • Pain is sharp and sudden.
  • The surface of the tooth show stains
  • Pain while chewing or biting food.
  1. Causes:

The outermost covering of the tooth is called enamel. It is the strongest substance in our bodies. It goes about as a protective layer for our teeth. Any kind of disruption or erosion of this layer exposes the inner part (dentin) of the tooth. Different dental conditions that might result in the exposure of the dentin are:

  • Cracked/chipped teeth
  • Gum recession
  • Enamel erosion
  • Tooth erosion
  • cavities

The inner layer of the tooth contains numerous microscopic channels or tubules. These tubules further lead to the pulp of the tooth, which contains numerous nerves. When individual drinks or eats hot, cold, or acidic food, channels of the exposed dentin allow these substances to reach the nerves. This results in sharp pain.

Common Causes Of Tooth Sensitivity:

Tooth Sensitivity

  – Brushing Too Hard / Using A Hard-Bristled Toothbrush

Many of us believe that brushing hard is good for our teeth. Well, the truth is, instead of doing any good, brushing hard causes lots of damage to the outer layer of the teeth. In the long run, the use of a hard-bristled brush or hard brushing wears down the enamel of our teeth. As a result, the microscopic tubules that lead to the innermost pulp get exposed.

The easiest solution is to brush gently and to use a soft-bristled toothbrush.

  – Teeth Grinding Or Clenching

Regular clenching or grinding of teeth results in the weakening or the erosion of the outermost layer of the teeth. As a result, the middle and the innermost layer of the teeth become exposed to external elements like hot, cold, or acidic food particles. When these food elements reach the nerves of the teeth, it causes pain or discomfort.

If you have a habit of grinding teeth then inform your dentist about the same. Mouthguards are available in the market, which would prevent you from grinding. You can even ask your dentist to get you a custom-made mouthguard.

  – Regular Consumption Of Acidic Foods And Beverages

Regular and too much consumption of beverages, sweet and acidic food results in enamel erosion. In addition to this, these food elements act as a trigger for tooth sensitivity. Hence, resulting in pain and discomfort. If you have a sensitivity issue, avoiding beverages and acidic food would help in preventing tooth discomfort.
