ToggleWhat Causes Sensitive Teeth After Whitening?
Teeth whitening and tooth sensitivity don’t have to go hand in hand if you choose the right teeth whitening services in Kirkland, Seattle, Washington. Here’s why your teeth might feel sensitive after whitening:

- The main whitening ingredient can irritate your tooth nerves and lead to discomfort.
- Whitening too often can wear down enamel, which makes teeth more sensitive.
- If your enamel is already thin, whitening can make sensitivity worse.
- Whitening gel can irritate gums, which can lead to tooth sensitivity.
- If your teeth were already sensitive, whitening could make it worse.
- Fillings, crowns, or veneers may react differently to whitening, which can cause sensitivity.
- Whitening can temporarily dry out your teeth, which makes them more sensitive.
- Scrubbing too hard after whitening can wear down enamel and increase sensitivity.
