Teeth Whitening for Kids

Tooth whitening is a procedure that lightens teeth and helps remove stains and discolouration. Whitening is one of the most popular cosmetic dental procedures and can significantly improve the appearance of your teeth.

Why do kids require tooth whitening?

Children and teens with discoloured teeth may have a negative self-image that can result in reduced self confidence. Teeth whitening may help them with their self-image.

It is also quite possible that kids have stains that are inside the tooth. These are called intrinsic stains. Intrinsic stains can be caused by fluorisis (exposure to too much fluoride as a child) while teeth are developing.
Stains may also be because of an injury or infection.
Another cause may be tetracycline antibiotics given to children 8 years old or younger when the teeth are still developing.
They may have surface stains caused by foods or drinks.

There are two types of teeth whitening procedures:

Bleaching:

This changes the colour of the tooth enamel and removes both surface stains and those deeper in the teeth. The chemical used to bleach teeth is generally carbamide peroxide.

Bleaching for children under age 18 is not suggested as there is greater risk of hypersensitivity. Bleaching using the light systems should be limited to age 18 and above due to the possibility of pulpal damage.

Whitening toothpastes:

These use a rough (abrasive) material that "scrapes" off surface stains and polishes the teeth.

Why is it important to discuss teeth whitening with your dentist?

If your child still has a mix of primary and permanent teeth, whitening all teeth may result in teeth being different shades of white. This is because the thickness of the tooth enamel is different in these two types of teeth. Colour will also change when the permanent teeth replace the primary.

Risks associated with tooth whitening in kids:

About one-third patients may experience tooth sensitivity and/or gingival irritation after bleaching treatment. This is more traumatic in children than in adults.
Studies show that repeated and prolonged exposure to whitening agents especially peroxide can be potentially harmful.
Degree of potential toxicity and harmful outcomes is high for those who overuse whiteners - a concern in teenagers.
Teeth whitening in healthy teens should be a case-by-case determination that must include the weighing of risks (oral health and age) vs benefits.

Good oral care and hygiene is an important part of a child's overall health. Your child can avoid unnecessary medical procedures and kick off to a good start by:
