Children have an insatiable appetite for all things that are sticky and fun to eat. The problem with these foods is that they are not good for teeth because plaques can appear quickly. This is formed by bacteria from the mouth and, when sugar is present, the plaque becomes sticky and attaches to the teeth. Sometimes, no matter how much or how often the child brushes his teeth, the plaque prevents them from looking white. But making these teeth whiter should not be too difficult, as there are many options to help your child achieve a bright smile.


  1. Visit the dentist. Children should see their dentist when they turn 1, according to the American Dental Association. If a child seems to be at risk for any problem, the dentist can apply topical solutions such as fluoride to help with future tooth decay and can also give a good cleaning to the teeth every six months or once a year.
  2. Brush your teeth twice a day with a small amount of toothpaste bleaching with fluoride. This helps to remove the starch and sugar from the teeth so that the white pearls can shine. As soon as your child has two teeth to touch, it is important to show him how to floss properly. This helps remove the plaque, which eventually hardens and turns into tartar. Until it is removed by a dentist, it covers the teeth and makes them appear yellowish.
  3. Purchase over-the-counter whitening strips for children with permanent front teeth. It should be around the age of 12, as all permanent teeth may not be present before, which can make their color inconsistent. Use these hydrogen peroxide strips as directed. The results may take a few weeks to appear.
  4. Ask the dentist if the whitening trays are an option and consult with your health insurance to see if it covers the treatment. These are filled with 10 percent carbide peroxide. The patient sleeps with the tray inserted for about four weeks.
  5. Investigate whitening at the dentist to see if your child’s teeth need to be bleached immediately. The dentist could first apply a protective layer to the gums and then put a whitening solution consisting of 15 to 35% hydrogen peroxide. The dentist then uses a heat laser to seal the solution.
