You’ve put in the time and effort to be a good parent and not only make sure your child is eating healthily but also that they’re staying active. So, why are you noticing white spots on the teeth of your toddler? There are 2 possible explanations for this, and there are easy ways to prevent this from happening again with the right oral care practices.

The White Spots on Your Toddler’s Teeth Are Early Signs of Cavities

As your child’s teeth develop, it’s important to make sure that you’re educating them on the right oral care while also making sure to brush their teeth.

This might sound alarming, but by seeing a dentist they’re able to reverse this so your child’s teeth are healthy once again. The dentist will clean any plaque and tartar off your child’s enamel and most likely provide a gentle fluoride treatment.

If you’re having a tough time brushing your child’s teeth it can be helpful to play their favourite song while you’re brushing. This can help them get used to the length of time it takes to brush their teeth and give them something to focus on other than the act of brushing.

The White Spots on The Teeth of Your Toddler Could Be Early Signs of Fluorosis

However, make sure you’re not brushing their teeth too often or using toothpaste that includes too much fluoride. If you’re noticing white spots on your toddler’s teeth, they could also be exposed to an excessive amount of fluoride. Known as fluorosis, it’s a cosmetic issue that occurs when babies or young children ingest too much fluoride while their teeth are still forming under their gums. It’s worth saying twice that if they do have signs of fluorosis, it’s cosmetic, meaning the actual integrity of their teeth is still ok.

Fluorosis-related white spots on baby teeth are frequently barely noticeable and, when present, typically appear streaky or blotchy. If you’re noticing these white spots, there are a few things you can do to prevent this from happening:

  • Make sure your child isn’t eating toothpaste as you’re brushing their teeth. You should only be putting toothpaste on their toothbrush the size of a grain of rice up until your child is three. Between ages three and six, it’s best to use a pea-sized amount.
  • Don’t give your child any kind of fluoride supplements unless prescribed by a dental or medical professional.
  • Don’t give your child mouthwash with fluoride until they are at least six years old.

Overall, white spots on your toddler’s teeth can be treated and the proper oral care can prevent them from showing up again.
