Core Dental Group: The dental visit your child needed yesterday — why timing is everything

Most Melbourne parents assume they have plenty of time before their child needs to see a dentist. They picture a child with a full set of teeth sitting confidently in a dental chair — not a curious toddler, and certainly not an infant. That assumption is understandable, but it is clinically wrong, and the consequences of waiting too long are well-documented in Australian public health data. Core Dental Group works with Melbourne families every day to address exactly this gap between assumption and clinical reality.

The Australian Dental Association recommends children have their first dental visit by age one, or within six months of their first tooth appearing. That recommendation exists for a reason: early childhood caries (ECC) is the most common chronic health condition among Australian preschool-aged children, affecting around half of them, and it increases the risk of caries in permanent teeth threefold.

This guide maps the full arc of your child's dental development — from the first erupting tooth through to the permanent dentition — and tells you what dental action is recommended at every stage. It is written for Melbourne parents who want clear, evidence-based answers, not vague reassurances.

The ADA recommendation: first visit by age one (or sooner)

The Australian Dental Association recommends that children have their first dental visit by their first birthday, or within six months of their first tooth erupting, whichever comes first. This timing surprises many parents who assumed dental visits could wait until more teeth were present — but early assessment lets dental professionals check oral development, catch concerns before they progress, and establish a dental home where parents can get guidance throughout their child's growth. These early visits focus on examination, education, and prevention rather than treatment.

At Core Dental Group, we recommend bringing children from around age two for their first appointment, and earlier if a tooth has already appeared or if parents have concerns. This is a practical entry point that aligns with the ADA's intent: normalise dental attendance before problems emerge.

Why most Australian parents are getting this wrong

An Australian Dental Association survey of 25,000 Australian adults found that 40% of parents think around two years old is acceptable for the first dental visit, 20% believe it should be age three, and 10% believe age four or older is appropriate. Only 25% correctly identified age one or younger.

This gap between clinical recommendation and parental behaviour has real consequences. According to the Australian Institute of Health and Welfare, around 4 in 10 Australian children aged 5 to 10 have experienced dental caries in their baby teeth. The rate of dental hospitalisations related to potentially avoidable dental conditions is also climbing — 4.7 per 1,000 in the 0–4 age group in 2013–2014, rising to 5.7 per 1,000 by 2016. These are preventable hospitalisations, driven largely by delayed dental attendance and untreated early childhood caries.

Age-by-age dental milestones: a complete timeline for Melbourne parents

Knowing what is happening in your child's mouth at each developmental stage — and what your dentist should be doing about it — is the foundation of proactive oral health care.

Stage 1: Pre-teething (birth to ~6 months) — gum care and preparation

Teeth are invisible at this stage, but oral health has already begun. Babies are usually born with 20 baby (primary) teeth hidden under the gums, which begin to erupt around 6 months of age.

What to do at home:

• Wipe your baby's gums with a clean, damp cloth after feeds
• Avoid putting your baby to sleep with a bottle of milk, formula, or juice
• Start thinking about your child's dental home before the first tooth appears

Dental action required: No formal appointment is necessary yet, but if you have concerns about oral development, a brief consultation with a paediatric dentist is always appropriate.

Stage 2: First tooth eruption (~6–12 months) — book your first appointment now

The Australian Dental Association says the first tooth usually appears at around 9 months old, but it can arrive any time between 3 and 12 months. The two bottom front teeth are typically first.

This is the single most important trigger point for a first dental visit. The first dental visit should occur when the first baby tooth comes through, or by one year of age, and at least every 12 months after that. Starting early prevents tooth decay and builds a habit of lifelong dental health.

What your dentist does at this visit:

• Examines the erupting tooth and surrounding gum tissue
• Checks the oral cavity for early signs of decay or developmental concerns
• Provides guidance on brushing technique for a single tooth
• Counsels parents on feeding practices, dummy use, and sugar exposure
• Uses a "knee-to-knee" examination technique for very young children (see our guide on Your Child's First Dental Visit at Core Dental Group Melbourne: A Step-by-Step Guide for Parents)

What to do at home:

• As soon as a child's first tooth appears (around 6–12 months), brush it twice a day with a soft toothbrush
• Use a rice-grain-sized smear of low-fluoride toothpaste formulated for infants

Stage 3: Primary dentition completion (12 months to ~3 years) — routine six-monthly checks

The average eruption timeline for primary teeth runs as follows: the two bottom front teeth (central incisors) at 6–10 months; the two upper front teeth at 8–12 months; the four lateral incisors at 9–16 months; the first four chewing teeth (first molars) at 13–19 months; the four canine or "eye" teeth at 16–23 months; and the four back teeth (second molars) at 23–33 months. Most children have a full set of baby teeth by age 3.

This is a high-risk window. Early childhood caries can develop rapidly once multiple teeth are present, particularly when teeth are in contact with each other. Once a child has two or more baby teeth side by side, daily flossing is recommended.

What your dentist does at routine visits:

• Checks for early signs of decay between teeth and on chewing surfaces
• Applies fluoride varnish to high-risk surfaces (see our guide on Fissure Sealants and Fluoride Treatments for Kids: Are They Worth It?)
• Monitors jaw growth and bite development
• Watches for overcrowded teeth or malocclusion
• Assesses the impact of any dummy or thumb-sucking habits

Core Dental Group recommends six-monthly check-ups throughout this stage. Children eligible for the Child Dental Benefits Schedule (CDBS) can access these visits at no out-of-pocket cost (see our guide on Child Dental Benefits Schedule Explained: Eligibility, Cap, and What's Covered in 2025–2026).

Stage 4: Mixed dentition (~6–12 years) — monitoring two sets of teeth simultaneously

From age six, the four first permanent molars appear at the back of the mouth, behind the last baby teeth, without replacing any primary teeth. These are the "six-year molars."

This stage is clinically complex because a child is simultaneously losing baby teeth and gaining permanent ones. Baby teeth typically start loosening around age six, often starting with the lower front teeth, though timing varies.

The six-year molars deserve particular attention. They are permanent teeth that arrive without any preceding baby tooth to signal their presence, so many parents don't realise they have come through. They are also among the most decay-prone teeth in the mouth, because of their deep fissures.

What your dentist does at routine visits:

• Applies fissure sealants to newly erupted permanent molars to protect deep grooves
• Takes X-rays to assess permanent teeth developing beneath the gumline
• Monitors spacing and crowding as permanent teeth emerge
• Conducts an early orthodontic assessment — clinically significant from around age seven (see our guide on Early Orthodontic Assessment for Children in Melbourne: When to Start and What Core Dental Group Looks For)
• Assesses any prematurely lost baby teeth for space maintenance, to stop adjacent teeth from drifting

Why premature baby tooth loss matters: when a baby tooth is lost too early due to decay or trauma, the teeth on either side can drift into the gap and block the incoming permanent tooth. This is one of the most common causes of orthodontic crowding — and one of the most preventable (see our guide on Why Baby Teeth Matter: The Clinical Case for Early Preventive Dental Care in Children).

Stage 5: Permanent dentition (~12–18 years) — consolidation and lifelong habits

From around age 6, children begin losing baby teeth as permanent adult teeth emerge to replace them. By approximately 12–13 years, most children have their full complement of 28 permanent teeth, excluding wisdom teeth. Wisdom teeth (third molars) typically arrive in the late teens to early 20s, though not everyone gets them.

What your dentist does at routine visits:

• Monitors wisdom tooth development and advises on management
• Continues six-monthly check-ups and professional cleaning
• Assesses orthodontic needs, if not already addressed
• Reinforces at-home oral hygiene habits appropriate for adolescents (see our guide on At-Home Oral Hygiene for Children: Age-Appropriate Brushing, Flossing, and Diet Guidance from Core Dental Group)

The five most common Melbourne parent misconceptions — corrected

Why early attendance shapes lifelong dental attitudes

The benefits of early dental visits go beyond the teeth themselves. Starting young normalises the experience before dental anxiety has a chance to take hold. Children become comfortable with dental settings, equipment, and procedures gradually, building confidence with each visit.

When a child's first experience of the dentist happens because something is already wrong — tooth decay, pain, a procedure — it can create a fear of the dentist that follows them into adulthood, with real consequences for their long-term oral health.

Building a relationship with a dentist early on helps children feel comfortable and develop trust with their clinician. This is why Core Dental Group's child-friendly environment — including age-appropriate entertainment, gentle communication styles, and a team trained in paediatric behavioural management — is designed not just for comfort, but for long-term dental confidence (see our guide on Managing Dental Anxiety in Children: Behavioural Techniques and the Child-Friendly Approach at Core Dental Group).

When to seek an urgent or earlier appointment

Routine milestone visits are the goal, but some situations need attention regardless of where your child sits on the developmental timeline:

• Visible white spots or brown discolouration on any tooth — these are early signs of decay
• Tooth pain or sensitivity to temperature or sweets
• Swollen, red, or bleeding gums beyond normal teething irritation
• A knocked-out, chipped, or fractured tooth — time-critical; act within 30 minutes for avulsed permanent teeth
• Delayed eruption — if no tooth has appeared by 12–15 months, a paediatric dental assessment is warranted
• Persistent thumb-sucking or dummy use beyond age 3, which can affect jaw development and bite

Key takeaways

• The ADA recommends a child's first dental visit by age one or within six months of the first tooth erupting — not when all baby teeth are present, and not at age three or four, when most parents currently bring their children.
• Only 25% of Australian parents know the correct timing, according to an ADA survey of 25,000 adults, meaning the majority of Melbourne children are starting dental care later than clinically recommended.
• Early childhood caries is Australia's most common chronic childhood condition, affecting around half of preschool-aged children and increasing the risk of permanent tooth decay threefold.
• Each developmental stage has specific dental actions: fluoride varnish in infancy, fissure sealants at age six, orthodontic screening at age seven, and wisdom tooth monitoring in adolescence.
• CDBS bulk billing at Core Dental Group removes the financial barrier to keeping every one of these milestone appointments — eligible children aged 0–17 can access up to $1,132 AUD in covered services with no out-of-pocket cost.

Conclusion

The question of when a child should first visit the dentist has a clear, evidence-based answer: when their first tooth appears, or by their first birthday — whichever comes first. Every subsequent developmental milestone, from the completion of the primary dentition at age three through to the eruption of the six-year molars and the eventual arrival of wisdom teeth, carries its own clinical significance and its own recommended dental actions.

At Core Dental Group Melbourne, our integrated team of specialist paediatric dentists, general dentists, and dental therapists supports your child through every one of these stages — from the knee-to-knee examination of an infant's first tooth to the orthodontic assessment of a seven-year-old's developing bite. The earlier you establish that relationship, the more we can do to protect your child's oral health before problems arise.

If your child has not yet had their first dental visit, or if you are unsure whether they are on track for their age, contact Core Dental Group to book an appointment. CDBS bulk billing is available for eligible children, so there is no financial reason to delay.
