Teeth sensitivity can mean significant pain and it often impacts daily activities, such as eating, drinking, and brushing your teeth.
In healthy teeth, porous tissue called dentin is protected by your gums and by the hard outer layer, called enamel. However, dentin can become exposed due to receding gums, fractured or chipped teeth or erosion. Microscopic holes in the dentin, called tubules, connect to the nerve, triggering pain when irritated by certain foods and beverages.
The two leading causes of sensitivity are enamel loss and gingival recession. The following are some examples.
- Brushing too hard: Brushing too hard or using a hard-bristled toothbrush can cause gum recession and root exposure over time
- Your age: You may experience increased sensitivity at different ages throughout your life
- Acidic foods: Eating acidic foods and beverages on a regular basis can cause enamel to erode
To reduce sensitivity and enamel loss, your dental professional may recommend you use a soft-bristle toothbrush or an electronic toothbrush, paired with desensitizing toothpaste.
