If you have sensitive teeth, you may experience some discomfort during and after the teeth whitening treatment. This is normal and usually goes away within a few days.

To help speed up the process, make sure to follow the instructions on your teeth whitening kit carefully. Avoid eating or drinking anything that could stain your teeth, and avoid smoking.

If you opt for an at-home kit, you’ll need to follow the instructions carefully to get the best results. Some kits require you to wear whitening trays for several hours a day or overnight. Others require you to apply the whitening gel to your teeth for a certain amount of time each day.

4. Risks and side effects associated with teeth whitening

Teeth whitening is generally considered safe. However, there are a few potential risks and side effects associated with the procedure.

This can lead to increased sensitivity to hot, cold, or sweet foods and beverages. Other potential side effects of teeth whitening include gum irritation, temporary tooth discoloration (from the bleaching agent), and increased tooth sensitivity.

In rare cases, teeth whitening can cause chemical burns to the gums or other tissue in the mouth. This is more likely to occur if the bleaching agent is not used correctly or if the person has an allergy to the bleaching agent.

If you are considering teeth whitening, it is important to talk to your dentist about the potential risks and side effects. They can help you decide if teeth whitening is right for you.
