Whiter teeth are often seen as a sign of confidence and good health. So, it’s no surprise that many parents, kids, and teens reach for teeth whitening products to brighten their smiles. But what happens if there are cavities hiding beneath the surface? Before you grab an over-the-counter whitening kit, here’s why mixing whitening and tooth decay isn’t the brightest idea.
Why Teeth Whitening and Cavities Don’t Get Along
Cavities are areas of decay that weaken tooth enamel. Whitening products often contain either hydrogen peroxide or carbamide peroxide, which work by penetrating the surface of teeth to lift stains.
When these two things collide, the treatment can seep deeper into the tooth, reaching sensitive layers and nerves.
The result is pain, increased sensitivity, and in some cases, worsening damage to the tooth! That’s why dentists recommend treating any cavities before beginning any whitening routine, even lower-concentration at-home products.
The Safest Way to Brighten a Smile
Now knowing that whitening can be harmful to compromised teeth, you can make a plan to help your child brighten their smile safely. If they’re interested in whitening, it’s best to start with a dental exam. A pediatric dentist can check for cavities, weakened enamel, or gum inflammation before giving the green light.
Once their smile is healthy, your dentist may suggest gentle over-the-counter (OTC) whitening products approved for younger patients. In other cases, where discoloration is less severe, they may suggest whitening toothpaste or rinses as a safer, low-strength alternative.
By taking your child to a pediatric dentist first, you ensure that they’re on a path to a brighter smile without the danger that can come with it.
When to Stop Teeth Whitening
Whitening is generally safe when approved by a trained pediatric dentist. However, if your child experiences sharp pain, sensitivity to temperature, or gum irritation while whitening, stop immediately. These symptoms are often a sign of hidden cavities or overexposure to whitening agents.
It’s natural to want your child to feel proud of their smile, but health should always come before cosmetics. Treating cavities and protecting enamel now will set your child up for a lifetime of brighter, stronger teeth.
