Dental advice for children
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.

Tooth development and eruption of permanent (adult) teeth
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.

Thumb sucking
Most children should grow out of thumb or finger sucking between 2 and 4 years of age. If sucking continues beyond 6 or 7 years of age, dental problems may begin such as:
- Buck teeth - excessive sucking can push the front teeth forward so they stick out over the bottom teeth. (see the Australian Society of Orthodontics
- Lisp - finger and thumb sucking can push the top teeth out of their normal position. This can make forming certain speech sounds difficult for the child, resulting in a lisp.
Seek professional advice on how to assist your child to stop sucking their thumb or fingers.

Tooth decay (dental caries)
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.

Teeth grinding in children
In most cases, children who grind their teeth don’t cause any damage to their teeth. In only a few very extreme cases, where the grinding is very regular, is it likely that your child could cause damage to teeth. If you’re concerned, talk to an oral health professional.
Teeth straightening and orthodontics
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 >>

Children and sweet drinks
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.
Knocked out baby tooth - what to do
Do not try to put it back.
You should not attempt to put a baby tooth back in its socket because:
- It may fuse to the socket, which leads to difficulties when it is time for the tooth to be shed.
- It may damage the permanent tooth underneath the socket.
