Causes of Sensitive Teeth

Have you ever had a sudden pain in your teeth when you eat or drink something hot or cold? This condition means you have sensitive teeth. Teeth become sensitive to what you eat or drink because the enamel or the outermost layer of your teeth begins to erode. Beneath the enamel of your teeth, there is another layer called dentin. Well, if your enamel is thinning, your dentin will automatically be more exposed or not protected properly so your teeth will become sensitive.

In addition to sensitive teeth to hot or cold foods, teeth can also be sensitive to foods or drinks that are sweet or too sour. Even though the sensitivity to your teeth doesn't last long, you need to have a checkup with your dentist to find out what is causing your sensitive teeth and how to fix it.

Here are some things that could be the cause of why your teeth are sensitive.

  1. The way you brush your teeth

If you brush your teeth too hard, not only will your gums hurt or the brush will be damaged easily, your tooth enamel will also erode over time. If the enamel that protects your dentin becomes thinner, your teeth will be more sensitive to the food or drink you consume. So make sure you brush your teeth carefully, okay?

  1. Tooth Erosion

The thinning of the tooth enamel layer can also occur if your teeth are exposed to acids from what you eat or drink. That's why it's very important to be diligent in brushing your teeth to minimize acid attacks from food or drink leftovers stuck to your teeth. If acids attack, not only the enamel on your teeth is affected, your gums will also gradually shrink and the roots of your teeth will open which will make your teeth more sensitive because the roots of teeth do not have enamel that can protect them.

  1. Gum Disease

Shrinkage of the gums can also occur if there is plaque or dental caries that builds up around your teeth and gums, which even if left unchecked can damage the teeth to the root because the gums are receding so it makes food scraps easy to stick out and become a breeding ground for bacteria.

  1. Teeth grinding habit

Grinding of teeth is also known as bruxism. This condition usually occurs when you sleep, when you are angry, or subconsciously you grind your teeth at indefinite times because it has become your bad habit. Well, grinding your teeth can also make your tooth enamel erode because the teeth are rubbed against each other. As a result, you also have sensitive teeth.

  1. Broken or Cracked Tooth

Broken or simply cracked teeth can damage the structure of the lining of your teeth, so your teeth can become sensitive. Tooth fillings that are starting to break can also make the filling teeth sensitive. So if you have a partially broken or cracked tooth, or your filling is starting to break, you should go to the dentist right away. Don't wait until your teeth are sensitive and problematic.

  1. Teeth Bleaching

One of the effects of teeth whitening or teeth whitening is that the teeth become sensitive. Usually this effect doesn't last long, but if your teeth are getting more sensitive and it lasts a long time to make you feel uncomfortable, it's better for you to immediately consult your dentist to overcome this.
