What Causes Tooth Sensitivity?

Posted on 1/2/2024 by Andrew Admin
Woman with dental pain due to gum disease.
Teeth sensitivity happens when your teeth feel uncomfortable or painful in response to hot or cold stuff. It can affect one tooth, several teeth, or all of them. This sensitivity can be a temporary or long-lasting problem. Most of the time, you can improve it by adjusting how you take care of your teeth. The following are the causes of tooth sensitivity.

Having Receding Gums

If your gums move away from your teeth, it means they are pulling back, showing the sensitive root of your tooth. This makes your teeth feel very sensitive.

Aggressive Brushing

Brushing too hard or using a side-to-side motion is the main reason for sensitive teeth. This damages the outer layer of the tooth called enamel, especially where it is thin near the gum line. If you brush more than you floss, consider changing your brushing technique to protect your enamel.

Teeth Grinding

Grinding or clenching your teeth can wear down the enamel, revealing the inner part called dentin. Sensitivity can also happen after getting crowns, fillings, or teeth whitening.

Gum Disease

Not cleaning your teeth for a while can create plaque or tartar in your gums, leading to gum disease. Gum disease irritates your gums, causing sensitivity in your teeth.

Cracked or Chipped Teeth

A tooth might get a crack that goes deep to its root beneath the gum. This can be super painful, especially when you have something cold, such as ice cream. The crack lets the cold get to the sensitive part of your tooth, making it hurt.

Dental Erosion

Teeth usually have a shield called enamel. When you consume lots of sour or acidic foods, like lemons, this shield slowly wears down. As it weakens, the inner part of your teeth, called dentin, becomes visible. Dentin is sensitive; when exposed, your teeth can feel more sensitive to things like hot or cold.
