The results of teeth whitening can last for several years, but this will depend on your lifestyle and habits. If you smoke or drink coffee, tea, or red wine, your teeth may become stained again over time. You can help keep your teeth white by brushing and flossing regularly and avoiding foods and drinks that can cause staining.

Teeth whitening works by using bleaching agents to remove stains and discoloration from teeth.

Teeth whitening is generally safe. However, it is important to follow the directions of your dentist or teeth whitening kit to avoid any potential side effects.
