Because tooth decay in the baby teeth can mean that a child will develop tooth decay in the adult (permanent) teeth, it is important that your child adopts good oral hygiene habits early in life. It is recommended that children have an oral health assessment by the age of two.

Teething usually occurs between the ages of 6 months and 3 years. Children usually replace their baby teeth at around 6 years of age. Back baby teeth are replaced at 10-12 years of age. If a child’s baby teeth erupted late, the adult teeth will probably erupt late as well.

Tooth decay is especially common in children, but anyone who has teeth can get tooth decay (dental caries), including infants and older adults.
When your child consumes food and drinks that are sugary or starchy (high in carbohydrates), the bacteria that naturally live in their mouth and in plaque, break down the carbohydrates into acids. These acids attack and dissolve the outer surface of the tooth (enamel). This process is known as demineralisation.
The first sign of demineralisation is a chalky white spot. At this stage, the decay process can be reversed. If you suspect your child has the start of tooth decay, make an appointment to see your dentist or other oral health professional.

Some children may require orthodontic treatment such as braces or plates to correct teeth and jaw alignment problems such as crooked or crowded teeth. It can be more difficult to keep teeth and gums healthy with all the wires and brackets needed to move the teeth.
It is vital that children clean their braces and plate every time they brush their teeth. Read about orthodontic treatment >>

Tap water is the best drink for children. Children do not need any sweet drinks to have a well-balanced and healthy diet. Sweet drinks include soft drinks and cordials, flavoured milks, flavoured mineral waters, sports drinks, energy drinks, fruit drinks and fruit juices. If parents do provide fruit juice, it should be diluted with water and limited to meal times to reduce risk of tooth decay.
Do not try to put it back.
You should not attempt to put a baby tooth back in its socket because:
