Is It Safe To Whiten My Child’s Teeth?

As parents, we can empathize with so many of our patients who are concerned that their children’s teeth aren’t perfectly white. After all, Hollywood tells us that anything less than a dazzlingly bright white smile is unacceptable. The truth is, most teeth are naturally different shades of off-white, yellow, and even gray. Baby teeth have a thinner coating of enamel compared to adult teeth, so a child’s first 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! 

Here at Boger Dental, we often hear from parents all asking the same question: is it safe to whiten my child’s teeth? While some methods can be safe for kids, not all are recommended for those under a certain age, and some can even do permanent damage to your teeth. Let’s take a closer look at some guidelines for professional teeth whitening in children, including when it’s considered safe and what options we offer to our patients! Keep reading below to learn more.

What do the experts say?

The American Dental Association (ADA) and the American Academy of Pediatric Dentistry (AAPD) both recommend waiting until a child’s full set of permanent teeth have grown in before attempting whitening treatments. This will generally happen somewhere between the ages of 13-15. Occasionally, some circumstances would lead us to consider whitening at a younger age. Some children are more susceptible to staining, for example, 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 are teased or anxious as a result of the way their teeth look. In cases like these, our doctors 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, baby teeth have a thinner coating of enamel than 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 of this solution, 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 discolorations to the teeth, especially when administered at home without expert supervision. 

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 further tooth hardening called the “enamel calcification process”. Any whitening treatment that’s administered before enamel calcification occurs is likely to damage a child’s teeth if not supervised or administered by a dental professional like Dr. Boger, Dr. Madden, Dr. Scherweit, Dr. Betterman, or Dr. Groth. If it is not, the strong chemicals found 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 as a result of over-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 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, preemptive 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 water and a variety of fruits and veggies 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 treatment and can be used regularly to help safely 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, we typically 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 professional supervision, these can damage your child’s teeth.
