Teeth Whitening: What Are the Risks?

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

“Teeth whitening” and “teeth bleaching” do not mean exactly the same thing.

Teeth whitening just means making your teeth whiter. Whitening on this level can be done simply with cleaning agents and over the counter whitening products.

Teeth bleaching is a type of teeth whitening that involves making the actual colour of the teeth themselves lighter, using hydrogen peroxide or carbamide peroxide.

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

Both types of teeth whitening treatments are considered safe when procedures are followed as directed. However, there are a few relatively minor risk associated with bleaching in particular that it’s important to know about.

Sensitivity

Bleaching can sometimes cause temporary sensitivity in the teeth to temperature. Some people experience spontaneous “shooting” pains down the centres of their front teeth.

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

Gum Irritation

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

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

Problems with Restorations

Teeth bleaching products do not work 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.

For this reason, many people choose to undergo a course of teeth whitening before their dental restoration procedures.
