Teeth Whitening For Kids

Yes, teeth whitening is an option for older children and teens, but there are important guidelines to follow before proceeding. At Kids Smiles Pediatric Dentistry in St. Louis, Dr. Kelly Jobe evaluates each patient individually to determine whether they are ready for whitening treatment. The process is safe and effective when done at the right stage of dental development, and a professional consultation is the best way to find out whether your child is a good candidate.

Most dentists, including the American Academy of Pediatric Dentistry, recommend waiting until a child is at least 14 years old before beginning any whitening treatment. By this age, all baby teeth have typically fallen out, the permanent teeth have fully erupted, and the enamel has had time to fully calcify and harden. Whitening the teeth too early can cause sensitivity or soreness and may not deliver the results you are hoping for. If your child is younger than 14 and has concerns about tooth discoloration, there may be other factors worth addressing first.

In addition to being at least 14 years old, your child should have all of their permanent teeth fully grown in, with the enamel completely calcified. Any orthodontic treatment, such as braces or aligners, should also be finished before whitening begins. Whitening before orthodontic treatment is complete can lead to uneven results, since the areas covered by brackets will not be treated. Dr. Jobe will review all of these factors at your child’s consultation before recommending a whitening plan.

There are a few common reasons. Permanent teeth are naturally larger and slightly more yellow in shade than baby teeth, so when both are present in the mouth at the same time, the contrast can make the permanent teeth appear more discolored than they actually are. Frequent consumption of soda, candy, and other staining foods and drinks can also contribute to yellowing over time. In some cases, discoloration may be related to enamel development or certain medications. Dr. Jobe can help identify the cause and recommend the most appropriate approach.

Yes, professional whitening is significantly more effective and safer for children than over-the-counter strips and products. Professional treatment delivers stronger, longer-lasting results and is supervised by a dentist who can anticipate and manage any sensitivity. The American Academy of Pediatric Dentistry cautions against over-the-counter whitening products for children because there is limited research on how these products affect developing teeth. Getting your child’s first whitening done professionally at our St. Louis office is the recommended approach.

When whitening is done at the appropriate age and under professional supervision, the risks are minimal. The primary concern with whitening too early is tooth sensitivity, which is more likely when the enamel is not yet fully developed. This is one of the reasons the age requirement exists. Dr. Jobe will assess your child’s enamel health and overall dental readiness before proceeding, and will walk you through any potential sensitivities or precautions specific to your child.

After whitening, there are several steps that help preserve the results. Using a whitening toothpaste as part of the daily brushing routine can help maintain brightness over time. Limiting stain-causing foods and drinks, including soda, candy, and dark-colored beverages, makes a meaningful difference. Keeping up with regular professional cleanings at our St. Louis office is also important, since removing plaque and surface buildup helps the whitening results last longer and keeps the teeth healthy overall.
