Your teeth can get fluoride in a number of different ways, including from toothpaste, specific fluoride applications and perhaps the drinking water in your area. These can all help to prevent tooth decay.
If you are unsure about how much fluoride you need in your toothpaste ask your dental team.
All children up to three years old should use a smear of toothpaste with a fluoride level of at least 1000ppm (parts per million). After three years old, they should use a pea-sized amount of toothpaste that contains 1350ppm to 1500ppm.
You can check the level of fluoride on the packaging of the toothpaste. Children should be supervised when brushing up to the age of 7. You should make sure that they do not rinse but spit out the toothpaste, and that they don’t swallow any if possible. This way the fluoride stays in the mouth for longer and will be more effective.
