Baby teeth development
Babies are born with a full set of 20 baby teeth hidden in their gums – 10 up the top and 10 down the bottom. As each baby tooth gets to the surface of the gum, the gum opens up to show the tooth.
Most first teeth appear between 6 and 10 months, but children get teeth at different times. In some children, teeth appear as early as three months. In others, they don’t arrive until around 12 months.
A very small number of children are born with one or two teeth.
Most children will have their full set of baby teeth by three years of age.
Dental care for baby teeth
As soon as the first tooth appears, use a soft infant toothbrush designed for children under two years. If your baby doesn’t like the toothbrush in his mouth, you can use a clean, damp face washer or gauze.
Brush with water only at least twice a day, particularly after the first and last feeds. Don’t use toothpaste at this age, unless recommended by your dentist. Find out how to brush baby teeth in dental care for babies.
It’s a good idea to see your dentist if your baby is born with teeth or when her first tooth comes through.
Preventing early tooth decay
Baby teeth are at risk of decay as soon as they come through. The fight against tooth decay starts early with a couple of simple precautions.
Babies aged 0-6 months need only breastmilk or formula.
Don’t put your baby to sleep with a bottle. When your baby is asleep, there’s less saliva in her mouth to protect her teeth. If your baby falls asleep with a bottle, formula or milk might slowly drip into your baby’s mouth and soak her teeth. This puts her at risk of tooth decay. Also note that putting your baby to sleep with a bottle is a choking risk.
If your baby likes a dummy, don’t dip it into food or liquids like honey or sugar. And don’t clean your baby’s dummy by putting it in your mouth. Make sure to wash and sterilise it instead.
