A child’s first dental visit sets the tone for how they feel about the dentist for years to come. A relaxed, positive first experience makes every future visit easier, and catching problems early means most children never need more than check-ups and simple preventive care.
Here’s what parents in Hornsby often ask about that first appointment.
When should my child first see a dentist?
The Australian Dental Association recommends a first visit when the first tooth comes through, or by around 12 months of age. That might seem early, but this first visit is mostly about prevention and getting your child used to the dental chair, not about treatment.
If you missed that window, don’t worry. It’s never too late to start, and any age is a good time for a first visit.
Why baby teeth matter
Baby teeth fall out eventually, so it’s tempting to think they don’t matter. In fact they:
- Help children chew and get good nutrition
- Support clear speech development
- Hold space for the adult teeth growing underneath
- Affect confidence and willingness to smile
Decay in baby teeth can cause pain, infection and early tooth loss, and can affect the adult teeth developing below. Tooth decay is one of the most common chronic conditions in Australian children, yet it’s largely preventable.
What happens at the first visit
For babies and toddlers
For very young children, the visit is short and gentle. Your child usually sits on your lap, sometimes in a “knee-to-knee” position with the dentist, so they can see you the whole time. The dentist will:
- Count and check the teeth, gums and jaw
- Look for early signs of decay, such as white chalky spots
- Check how teeth are coming through
- Talk with you about brushing, diet, bottles, dummies and thumb sucking
For older children
Preschool and school-aged children usually sit in the chair on their own (with you nearby). Depending on their age and needs, the visit may include:
- A full check of teeth and gums
- A gentle polish and clean
- X-rays if the back teeth are touching and we need to check between them
- Fluoride to strengthen enamel
- A discussion about fissure sealants for newly erupted adult molars
We explain each step in simple, friendly words, let children hold the mirror and “count” their own teeth, and never rush. If a child is upset, we’d rather stop and try again another day than create a bad memory.
How to prepare your child
- Talk about it positively. Explain that the dentist will count their teeth and check they’re strong and healthy. Avoid words like “hurt”, “needle” or “drill”, even to reassure (“it won’t hurt”), as these can plant worries.
- Read a book or watch a short video about visiting the dentist together.
- Play dentist at home. Take turns counting each other’s teeth, or check a teddy’s teeth.
- Choose a good time of day. Morning appointments often suit young children best, when they’re fresh and not hungry or tired.
- Stay calm yourself. Children pick up on adult nerves. If you feel anxious about the dentist, try not to share that in front of them.
- Bring a comfort toy if it helps.
Brushing at home by age
- First tooth to 18 months: clean teeth twice a day with a soft infant brush and water only, unless your dentist advises otherwise.
- 18 months to 6 years: use a pea-sized smear of low-fluoride children’s toothpaste twice a day. Encourage your child to spit, not rinse.
- 6 years and over: a pea-sized amount of regular fluoride toothpaste.
Children usually need help brushing until they can tie their own shoelaces, around 7 or 8. Start flossing once teeth touch.
Food and drink habits that protect teeth
- Water and plain milk are the best drinks. Fruit juice, cordial, flavoured milk and soft drinks are high in sugar and acid.
- Don’t put babies to bed with a bottle of milk or juice. Milk pooling around the teeth overnight is a common cause of early decay.
- Keep sweet foods to mealtimes rather than spreading snacks through the day.
- Choose tooth-friendly snacks such as cheese, plain yoghurt, vegetables and fruit.
- Be wary of sticky dried fruit and “healthy” bars, which cling to teeth.
Common problems we look for in children
Early decay
The first sign of decay is often a white, chalky band near the gum line of the top front teeth. At this stage it can sometimes be reversed with fluoride and better brushing. Left alone, it turns brown and forms a cavity.
Decay in the back teeth
The chewing surfaces of molars have deep grooves that trap food. They’re the most common place for decay in school-aged children, which is why we check them carefully and discuss sealants when the adult molars come through around age 6 and 12.
Crowding and bite problems
Teeth that are very crowded, a bite where the top teeth sit behind the bottom teeth, or a large overbite can be easier to manage when spotted early. We’ll let you know if an orthodontic review would be helpful.
Damage from falls
Toddlers learning to walk and children playing sport often bump their front teeth. Even if a tooth looks fine, a knock can damage the nerve, so it’s worth having it checked. A tooth that darkens weeks after an injury needs a review.
Enamel defects
Some children have patches of weaker or discoloured enamel, which can be more prone to sensitivity and decay. These teeth may benefit from extra fluoride or protective coatings.
How often should children see the dentist?
Most children do well with a check-up every six months. Your dentist may suggest more frequent visits if your child has had decay, has special needs, or is at higher risk. From around age 7 to 10, check-ups also include keeping an eye on how the adult teeth and jaws are developing, and whether an orthodontic assessment would help.
Family appointments
Parents can book back-to-back appointments so the whole family is seen in one visit, including on Saturdays from 8:30am to 4pm. Children often relax more after watching a parent or sibling have their check-up first.
Children’s dentistry FAQs
My child is scared of the dentist. What can we do?
Tell us when you book. We can schedule a shorter “meet the dentist” visit, take extra time, and go at your child’s pace. See our gentle dental care page.
Are dental x-rays safe for children?
Yes. Digital dental x-rays use a very low dose, and we only take them when they’re needed to check for decay between teeth or how teeth are developing.
Should I worry about thumb sucking or dummies?
Most children stop on their own by around age 3 to 4. If it continues once adult teeth start coming through, it can affect how teeth and jaws grow, so mention it at a check-up.
What should I do if my child knocks out a tooth?
For a baby tooth, don’t try to put it back; call us for advice. For an adult tooth, act quickly: see our guide to knocked-out teeth and call us straight away.
