What is Teeth Sensitivity?
Teeth sensitivity, also known as dentin hypersensitivity , is a common dental condition where you experience a sharp, sudden pain or discomfort in your teeth when exposed to certain triggers. These triggers can include:
- Cold or hot foods and drinks (like ice cream or coffee)
- Sweet or acidic items (such as candy or citrus)
- Cold air (especially during inhaling through the mouth)
- Brushing or flossing
Causes of Teeth Sensitivity

- Patients with bruxism can have sensitive teeth.

Things to Know before Buying Any Teeth Whitening Product
Before exploring teeth whitening kits for sensitive teeth, it is important for you to always read the ingredients carefully before buying any teeth whitening for sensitive gums. In the ingredients section, see the active ingredients concentration. If it is used in a lower percentage, that product is meant to be for sensitive teeth. Teeth whitening kits with a higher concentration of active ingredients are perfect for people with normal teeth and gum health, which may give you results sooner than those of lower active ingredient concentration products.
