Baby teeth develop while babies are still in the womb. Newborns have a full set of 20 baby teeth hidden in their gums.
Most baby teeth appear between 6 and 10 months. In some children, teeth appear as early as three months. In others, they don’t arrive until around 12 months. Different children get teeth at different times. A very small number of children are born with one or two teeth.
Baby teeth can arrive in any order, although the central bottom teeth are often first. All the baby teeth will usually arrive by the time your child is three years old.
The 32 adult teeth replace the baby teeth between the ages of 6 and 20 years. You can’t replace these teeth, so you have to look after them.
Each baby tooth appears (‘erupts’) slowly over several weeks or months. As it gets to the surface, the gum opens up to show the tooth.
Many people think that ‘teething’ babies:
There’s debate about whether these signs are caused by teething. They might just be a normal part of development or a result of minor infections and illnesses. If your baby isn’t well, it’s always best to take her to the doctor, especially if she has a fever or diarrhoea, or you’re worried about any other symptoms.
Things to try
If you’re concerned about your baby’s teething, you can try:
If your baby still seems unhappy or uncomfortable, it’s time to see your doctor or child health nurse. Teething might not be the problem.
You can start cleaning and caring for your baby’s gums well before the first tooth appears. A couple of times a day, just wipe her gums gently using a clean, damp face washer or gauze.
As soon as teeth arrive, you can clean them twice a day (in the morning and before bed). Wrap a clean, damp face washer or gauze around a finger and wipe the front and back of each tooth.
If your baby doesn’t mind, you can introduce a small, soft toothbrush designed for children under two years. Use only water on the toothbrush until your baby is 18 months old (unless a dentist tells you to do something else).
Once your child is 18 months old, you can use a pea–sized smear of low-fluoride toothpaste on the toothbrush.
The best way to clean your baby’s teeth
After cleaning your baby’s teeth and gums, rinse the toothbrush with tap water.
Store the toothbrush upright in an open container to allow it to air-dry.
If other family members’ toothbrushes are stored in the same place, make sure the brushes don’t touch. This reduces the risk that decay-causing germs will travel between brushes and into your baby’s mouth. And there’s no sharing when it comes to toothbrushes! One for each family member is best.
Toothbrushes should be replaced every 3-4 months, or when the bristles get worn or frayed.
Children should have an oral health assessment by age two.
