Choosing the best kids toothpaste for a child in Singapore

A good kids toothpaste is one your child will actually let you use twice a day, in the right amount for her age. The NHS puts that amount at a smear up to age 3 and a pea from 3 to 6. Fluoride strength matters more than flavour, and Singapore tap water already supplies some.

That last point changes the calculation here, and most toothpaste articles are written for countries where it does not apply.

Does a child in Singapore need fluoride toothpaste?

Fluoride is the best-evidenced way to prevent tooth decay, and nothing on a natural-products shelf matches it. The NHS asks for toothpaste containing no less than 1,000ppm fluoride for children up to age 3, more than 1,000ppm from 3 to 6, and at least 1,350ppm for older children and adults.

Singapore adds a second source. Our public water supply is fluoridated, a long-standing Ministry of Health policy, so a child who drinks tap water is already getting fluoride systemically. A child who drinks only bottled or filtered water may not be.

Both things are true at once. Fluoride works, and your child here is probably not starting from zero.

How much to use, by age

The last column matters most. A child under 6 will swallow a good share of whatever you put on the brush, and swallowing fluoride paste daily over years is what causes the mottling called dental fluorosis.

Teach spitting early. Rinsing with water afterwards washes the fluoride straight off the teeth, so spit and leave it.

What to look for on the tube

• A fluoride figure in ppm, printed somewhere on the pack. A paste that only says "with fluoride" tells you nothing.
• A flavour she tolerates. Strong mint burns a small mouth. Mild fruit or a gentle mint gets used.
• No sodium lauryl sulfate if your child gets recurrent mouth ulcers. The evidence is modest, and it is a cheap change to try.
• No triclosan. It is restricted rather than banned in this region, and there is no reason for it in a child's paste. We go into that in our piece on triclosan.
• A soft, small brush head. The brush does more of the work than the paste.

Guardian, Watsons and Unity all stock a reasonable range, and the fluoride strength is usually in small print on the back rather than the front.

Does xylitol earn its place?

Xylitol is a sugar alcohol that decay bacteria cannot ferment, so it does not feed them the way sucrose does. That is the mechanism, and it is sound.

The clinical question is whether a xylitol product measurably prevents cavities. A Cochrane review of xylitol-containing products for preventing dental caries found the available evidence low in quality. So treat it as a sensible sweetener rather than a protective ingredient worth paying extra for.

When a fluoride-free paste is the right call

Two situations make it reasonable, and neither has anything to do with fluoride being dangerous.

A child who swallows instead of spitting. Below roughly age 3, many do. With a fluoride-free paste you stop counting, and with a fluoride paste you use a rice-grain smear and supervise. Both are legitimate, and your dentist can tell you which fits your child.

Total fluoride exposure that is already high. If she drinks a lot of tap water, has had fluoride varnish applied, or takes a supplement a dentist prescribed, trimming one source is a defensible choice.

For the first of those, we make our Baby & Kids Toothpaste: a fluoride-free paste for children from 6 months, with xylitol and hydroxyapatite, no SLS and no added sugar, in strawberry, bubble gum and orange. Regular brushing with it may help fight tooth decay, and the fruity flavours help with reluctant brushers. In a 2023 use test, 91% of 32 mothers said they would swap their child's usual toothpaste for it. (Our Non-Fluoride Toothpaste is the mint one made for pregnancy, for adults and children over 5.)

If your child has already had a filling, ask your dentist before moving away from fluoride.

Where fluoride should stay. Any history of decay, any white spots a dentist has flagged, any child old enough to spit reliably without being reminded. In those cases the protection is the point.

Making twice a day actually happen

Brushing starts with the first tooth, and gum wiping before that. Night brushing is the one that counts most, because saliva flow drops during sleep and whatever is left on the teeth stays there.

What tends to work:

• Brush at a fixed point in the routine, after the bath rather than after milk.
• Stand behind her at a mirror and tilt her head back against you.
• Give her a brush of her own to chew while you do the real pass.
• Count aloud, or use a song, so two minutes has a shape.
• Stop giving milk or juice in bed. A bottle at night pools sugar against the upper front teeth, which is where early decay shows up first.

Our longer guide to teeth and gum care in infants and toddlers covers technique by age, and common dental problems in children covers what the trouble usually turns out to be.

When to get a dentist involved

By her first birthday, or as soon as the first tooth is through. The AAP sets it that early for a reason, which is that early decay in milk teeth is common, painless at first and invisible to a parent until it is not.

Do not wait for the School Dental Service. It is a good scheme and it reaches children in primary school, by which point several years of brushing habits have already set. Private paediatric dentists and KKH both see toddlers.

Anything that looks like swelling along the gum line, a tooth that has turned grey after a fall, or a child holding one side of her face needs an appointment that week. Swollen gums in children is the other page to read if that is what you are looking at right now.
