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 deciding about this cosmetic dental procedure.
“Teeth whitening” and “teeth bleaching” do not mean exactly the same thing.
Teeth whitening just means making your teeth whiter. Teeth whitening can be done with a number of teeth cleaning agents and over the counter whitening products.
Teeth bleaching is a type of teeth whitening that involves using hydrogen peroxide or carbamide peroxide to make the actual colour of the teeth themselves lighter.
Because teeth whitening encompasses teeth bleaching, these terms are often used interchangeably.
Teeth whitening treatments are considered safe when procedures are followed as directed. However, there are a few relatively minor risk associated with bleaching that you should be aware of.
Sensitivity
Bleaching can sometimes cause the teeth to become temporarily sensitive 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.
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.
To prevent this from becoming an issue, many people choose to undergo a course of teeth whitening before their dental restoration procedures.
