• Why Do Teeth Become Sensitive?

    What causes tooth sensitivity?

    There are quite a few different reasons why your teeth become sensitive. For an accurate diagnosis, it helps to consult a dentist to find out why it’s happening to you.

    Sensitive teeth may be caused by these dental issues –

    • Hard toothbrushing: Wearing down the enamel of your teeth from aggressive brushing or using a toothbrush with bristles that are too firm.
    • Acidic foods and drinks: The acid in some foods and beverages can lead to tooth erosion. A condition which leaves your surface of your teeth weakened and vulnerable nerve sensations.
    • Tooth decay: Decay exposes the dentin of your tooth which is where blood vessels and nerves can be impacted. Changes in temperatures or pressure become very noticeable even causing pain.
    • Receding gums: With age or illness our gums may shrink and leave the tooth root exposed. This part of your tooth is not protected with enamel and is very sensitive.
    • Teeth grinding: All that rubbing and wearing of tooth-on-tooth from tooth grinding damages the enamel of your teeth. Once the enamel is weakened the dentin is exposed and your teeth become sensitive.
    • Tooth-whitening toothpaste: Just like you might not be able to take some types of headache tablets but you can take others. The chemicals in some tooth-whitening toothpastes can create a sensitive tooth reaction in some people.
    • Dental procedures: Tooth sensitivity can be common after some types of dental procedures. Those that are “invasive” such as crown or bridge work, even having fillings. This type of sensitivity is usually temporary and disappears as the health of your mouth returns.
    • Cracked or chipped tooth: Any crack, even a fracture that is invisible to the naked eye can be the cause of teeth becoming sensitive.

    You can alleviate tooth sensitivity by changing to a toothpaste for sensitive teeth. If your sensitivity is extreme and persists no matter what you do, see your dentist for an evaluation and advice on the best way to manage your situation.
