Teeth Whitening For Children’s Teeth: Is It Safe?

If Hollywood is anything to go by, a dazzling bright white smile is the norm and anything less than that is unacceptable. This is reinforced by movies and television even in children’s programs, but the truth is, most teeth are different shades of off-white, yellow, and even gray. The primary teeth have a thinner coating of enamel compared to adult teeth, so baby teeth will usually appear quite a bit lighter than adult teeth. Even normal variations in color can be startling once a child’s baby teeth fall out and their permanent teeth grow in! This may raise questions about teeth whitening for children’s teeth, in specific, is it safe?

Here at Accent Smile Center, we often hear from parents wondering if it’s possible to brighten their child’s smile through at-home products or our glow whitening process. While some methods can be safe for kids, not all are recommended for those under a certain age. Let’s take a closer look at the general guidelines for professional teeth whitening in children, including when it’s considered safe and what options we have available for our patients! Keep reading below to learn more.

What the experts have to say

The American Dental Association and American Academy of Pediatric Dentistry have both recommended waiting until all of the permanent teeth have grown in before attempting whitening treatments. This will generally be somewhere between the ages of 13-15. Occasionally, there are circumstances that would lead us to consider whitening at a younger age. For example, some children are more susceptible to staining, while braces, illness, and injury can sometimes leave noticeable areas of discoloration. They may feel unhappy or self-conscious about their smile, especially if they experience teasing or social anxiety as a result of the way their teeth look. In cases like these, Dr. Gatgens will discuss the available options with the parents and patient to determine which approach is best. 

Why do experts recommend waiting? As we mentioned above, a child’s baby teeth have a thinner coating of enamel than their permanent teeth will. This makes them appear brighter, but it also means they have less dentin and pulp, which is the living connective tissue inside each tooth. Most whitening products, including strips, gels, and pens, use a hydrogen peroxide solution to bleach the teeth. The higher the concentration, the higher the chances of it causing problems in a child’s teeth. These issues can range from increased tooth sensitivity to demineralization of the dentin. High concentrations of hydrogen peroxide may also lead to further variations in the color of the teeth. 

Are there any risks to using teeth whitening products on children?

Ideally, no teeth whitening products should be used until the tooth pulp is fully formed and the permanent teeth have all grown in completely. This usually occurs by the age of 12-13, and is followed by a year or two of the enamel calcification process. Any whitening treatment that’s administered before this time has the potential to damage a child’s teeth if it’s not supervised or administered by a dental professional like Dr. Gatgens. If it is not, the strong chemicals used in most teeth whitening agents can:

  • damage the gum tissue
  • injure the tooth pulp or nerves
  • disrupt crowns, fillings, or veneers
  • cause enamel pitting or disintegration

Additionally, overuse of at-home treatment methods can result in the tooth structure breaking down due to too much oxidation. Whitening a child’s teeth without professional guidance may also mask certain underlying causes for discoloration, thus delaying the appropriate treatment. These causes can include:

  • injury to a tooth
  • some iron supplements and vitamins
  • early childhood tooth decay
  • some types of medications and antibiotics

In cases of extreme discoloration, a dentist can safely treat the affected teeth if necessary in order to minimize the impact on the surrounding teeth and gums.

Are there any alternatives to teeth whitening treatments for children?

For children still in possession of some baby teeth, stain prevention will often be the safest way to keep their smiles bright and white! There are several ways to do this, a few of which we’ll outline here.

Avoid foods and drinks that are known for staining teeth

Soda, some fruit juices, and treats loaded with bright dyes can easily stain the teeth, especially when consumed regularly. Encourage children to stick to sparkling water and a variety of fruits instead!  

Use a whitening toothpaste

A good dental hygiene routine will help prevent staining. This includes brushing twice a day for at least two minutes each time and flossing every night before bed. A pea-sized amount of whitening toothpaste is gentler than treatments and can be safely used to help brighten a child’s teeth.

Regular dental visits

Children should see a dentist every six months for a thorough cleaning and exam. These visits help prevent tooth decay and cavities, detect any issues requiring attention, and keep a child’s mouth healthy and happy throughout the year!

When it comes to teeth whitening treatments for children, it can be safe under certain circumstances. We do believe it’s best to be safety-conscious and conservative, however. Unless there are special circumstances to consider, we recommend waiting until the permanent teeth have completely grown in, and preferably a couple of years after that. For most children, this will be once they hit their mid-teens. We also encourage parents to check with us before using any over-the-counter products designed to whiten the teeth, like pens and gels. If used too frequently or without supervision, these can damage your child’s teeth. 

At Accent Smile Center, we understand that many parents and children have cosmetic concerns about their smiles. Your child’s health and safety are our top priority, and we’re committed to working with you towards the best and healthiest solution for their teeth!
