Fluoride for Under-5s: Facts & Myths
Fluoride helps protect against tooth decayIn this article, we look at fluoride use and its importance during children’s early years in the fight against tooth decay. This includes useful facts and guidelines for parents, the recommended fluoride content in toothpaste for babies and under-fives, as well as dispelling a common myth around unproven fluoride health concerns.

Fluoride

As well as being found in commercial toothpastes, fluoride is naturally found in several foods, including fish and tea, as well as in the drinking water supply. It’s a natural mineral that hugely benefits the population by significantly reducing tooth decay. This is achieved through a reduction in the effects of acid produced by bacteria in the mouth, as well as by strengthening tooth enamel.

It’s interesting to note that children whose teeth are regularly exposed to fluoride when their young teeth are developing tend to have a reduced amount of grooving in the surface of their teeth. This allows harmful plaque to be removed much more easily, again helping to fight tooth decay.

“Research over 60 years shows that 0.7 to 1.2 parts per million of fluoride in the water supply reduces tooth decay by between 40 and 60%”

For that reason, where the natural water supply falls below this fluoride strength, additional fluoride is often added by the water companies, in order to make up the shortfall. The amount varies from place to place, though, and can be checked by contacting your local water supplier.

Fluoride in Toothpaste – How Much is Right for Your Child?

How much fluoride is right for babies and under-fives?The correct fluoride content in toothpaste usually* depends upon the age of your child.

For babies and toddlers aged under 3, use a children’s or family toothpaste containing at least 1,000 parts per million (ppm) of fluoride, but no more than 1,500ppm. Just a smear is enough for children of this young age and the little one does not need to rinse their mouth afterwards. Indeed, leaving a tiny bit of toothpaste residue in the mouth will protect their teeth for longer. Their teeth should be brushed at least twice every day from the moment the first tooth appears.

Children aged between 3 and 6 should also use toothpaste containing between 1,000ppm and 1,500ppm of fluoride, but this time they should use a pea-sized amount on their toothbrush. As with babies, the children do not need to rinse (so that the effects of the fluoride last longer) but they can, of course, spit out after brushing. Again, they should brush twice a day as a minimum.

* If a child has a higher risk of tooth decay for any reason, a dentist may recommend a higher strength toothpaste.

Brushing Should Be Supervised

Children’s teeth brushing should be closely supervised by a parent or responsible adult until they are at least 7 years old. This is to ensure that teeth are being brushed properly and thoroughly, as well as for safety reasons. Children must never associate toothbrushes with playing, and certainly must never run around with them in their mouths.

Fluoride Varnish

The NHS suggests that children aged 3 or more would benefit from a coating of fluoride varnish two or more times per year. This is something that’s available from dentists and involves a coating of varnish being applied to the teeth. The varnish contains high levels of fluoride and helps the teeth to resist decay and it also strengthens enamel. Even baby teeth can be protected by fluoride varnish. The varnish is particularly useful to anyone who is particularly at risk of developing, or is naturally prone to, tooth decay, or who suffers from a condition called dry mouth.

Does Fluoride Do Any Harm?

Learn the facts about fluorideFluoride has been of enormous benefit to millions of people around the world, significantly reducing tooth decay in rich and poor communities alike, even when present only in the water supply. According to both the Oral Health Foundation and the NHS, fluoride is absolutely safe for both children and adults. While there are some that say it can be linked to a variety of health conditions, there has been no compelling evidence to scientifically back up the claims.

One exception to that rule is the possibility of developing dental fluorosis, which is a condition caused by exposure to too much fluoride when young teeth are developing (typically below the age of 7). In mild cases, it may cause flecking or white lines on the surface of the teeth. In more severe cases, pitting and discolouration may occur. However, in the UK, the condition only rarely occurs in a way that adversely affects the appearance of teeth, not least because fluoride levels in water supplies are carefully monitored by an official body set up to do so — the Drinking Water Inspectorate (‘DWI’).

A Note About Sugar

This article is geared towards increasing parent knowledge around fluoride use and its importance during children’s early years. Before we sign off, though, it would be remiss of us not to mention that one of the best ways to avoid tooth decay is, of course, to avoid added sugar in both food and drinks. When sugar coats teeth, plaque is likely to build up and then your children are more at risk of tooth decay. It’s even worse when the sugar coating and subsequent plaque are left for longer periods. Hence, it’s important to both avoid unnecessary sugar in the first place and to brush children’s teeth regularly to remove it. We cover this and related brushing guidelines in our separate teeth brushing guide for babies, toddlers and young children, here.
