What are the risks to teeth whitening?

Though the risks associated with teeth whitening are relatively minimal, there are still some important factors our Surrey dentists want patients to consider when they are considering this cosmetic dental procedure.


Teeth whitening simply means making your teeth whiter. Teeth whitening can be done with a number of teeth cleaning agents, or over the counter products.

Teeth bleaching is a type of whitening which involves hydrogen peroxide or carbamide peroxide. It makes the colour of the teeth themselves lighter.

Because teeth whitening encompasses teeth bleaching, these terms are often used interchangeably.

Teeth whitening treatments are safe when procedures are followed as directed. However, there are a few relatively minor risk associated with bleaching that you should be aware of.


Sometimes, bleaching can cause teeth to become temporarily sensitive to temperatures. Some people experience a spontaneous pain down the center of their front teeth.

Sensitivity after teeth whitening usually fades away after a few days.

Gum Irritation

More than half of the people who use peroxide-based whitening systems experience mild gum irritation as a result of the bleach concentration or contact with the trays.

Gum irritation can last for several days after the bleaching process is complete.

Problems with Restorations

Teeth bleaching products will not have any affect on dental restorations, such as dental crowns, fillings, or veneers. If you have a restoration and try to whiten your teeth, the restoration will stay the same colour.
