Our Winnipeg dentists do not recommend teeth whitening for children in any form. There are two main reasons for this:
Your child's teeth are not actually stained
Your child's adult teeth may appear stained when they first come in, especially when compared to the baby teeth that remain in the mouth. As a result, they ask whether it would make sense to have their children’s teeth whitened.
However, it’s completely normal for adult teeth to look more yellow than baby teeth. This happens because adult teeth contain significantly more dentin (the layer of the teeth directly beneath the enamel). Dentin is yellow in colour and can make the adult teeth appear unusually yellow when they’re next to baby teeth in the mouth.
This perceived discolouration typically sorts itself out once all the baby teeth have fallen out. For this reason, whitening is usually completely unnecessary for children and young teens.
There have been no studies showing the effects of whitening on children's teeth
Most dentists will not whiten children’s teeth because the fact is, we simply don’t know if it’s safe to do so. There is little data available to tell us what the effects of whitening agents would be on teeth that are still developing, and so it is best to be careful with the health of your child's teeth.
Common causes of discolouration in children's teeth
There are many possible causes of teeth discolouration in children:
- Poor dental hygiene habits
- Pigmentation due to food and beverage stains
- Intake of medications that contain iron (vitamin supplements)
- Decalcification of enamel due to the removal of braces
- Nerve damage or tooth trauma
- Excessive fluoride due to use of infant formula combined with fluoridated water
- Tooth decay
- Mother is taking tetracycline while pregnant or breastfeeding
- Medical conditions that hinder teeth development during infancy
How you can help prevent your child's teeth from staining
Since teeth whitening procedures are not an option, your child or teen can still help prevent staining and discolouration with the use of whitening toothpaste. Additionally, foods and drinks that cause staining, such as dark sodas, can be avoided.
