People with particularly sensitive teeth can find teeth whitening too painful and may not be suitable for the treatment. If you experience an amount of pain which is not predicted by your dentist or product information you ought to halt the process immediately and consult your dentist about the possible causes of the pain and whether there have been any other side effects. You should discuss what the treatment will feel like with your dentist or carefully read the safety and application information if you are using the product on yourself at home.

Throughout the treatment your lips and gums might need to be protected which might involve them being covered or held back by a shield which can also be slightly uncomfortable. Some products which use light, heat or lasers to activate the product might make the process a little uncomfortable. The product should only be applied to the teeth, and only topically, and should not come into contact with any nerve endings. This typically happens when using a one-size-fits-all, ill-fitting gel tray or applying too much gel.

The tooth whitening process should not be a painful one. Wipe: If the whitening agent comes anywhere near your gums, wipe it off immediately with a soft, damp swab.
