“It’s just a baby tooth — it’ll fall out anyway.” This is one of the most common misconceptions in paediatric dentistry, and it can lead to serious consequences. Baby teeth are not disposable placeholders. They serve essential roles in a child’s oral development, and untreated decay in baby teeth is the leading cause of preventable childhood dental pain and hospital admissions in Australia.

The Australian Institute of Health and Welfare reports that dental conditions are the most common cause of preventable hospitalisation among children aged 5 to 9 in Australia. The majority of these admissions involve untreated decay in primary (baby) teeth. At verified Townsville clinics, our children’s dentistry team treats baby tooth decay promptly and gently to prevent pain, infection, and long-term complications.

Why Baby Teeth Matter

Baby teeth serve four critical functions that affect your child’s health and development:

1. Space Maintenance

Each baby tooth holds space in the jaw for the permanent tooth developing beneath it. When a baby molar is lost prematurely due to untreated decay, the adjacent teeth drift into the gap within weeks. By the time the permanent tooth is ready to erupt — sometimes years later — there is insufficient space, leading to crowding, impaction, or misalignment that requires orthodontic treatment.

2. Jaw Development

The forces generated during chewing stimulate jawbone growth. Missing or painful baby teeth reduce chewing, which can affect jaw development and facial symmetry.

3. Speech Development

The front baby teeth are essential for producing certain sounds correctly (particularly “th,” “s,” “f,” and “v”). Early loss or significant decay of front teeth can affect speech clarity during critical language development years.

4. Nutrition and General Health

Children with untreated decay often avoid eating due to pain, leading to reduced food intake, nutritional deficiency, and in severe cases, failure to thrive. Chronic dental infection also contributes to systemic inflammation.

What Happens When Baby Tooth Decay Is Left Untreated

StageWhat HappensSymptoms
Early decayWhite or brown spot on enamelNone — only visible on examination
Moderate decayCavity through enamel into dentineSensitivity to sweet, hot, or cold
Deep decayCavity reaching the pulp (nerve)Spontaneous pain, pain at night
AbscessInfection spreads beyond the tooth rootSwelling, facial pain, fever
Premature lossTooth falls out or requires extractionSpace loss, adjacent teeth drift

Early detection and treatment with a simple filling ($150–$300) prevents progression to stages that require more invasive and costly procedures such as pulpotomy (baby root canal, $250–$450), stainless steel crown ($300–$500), extraction ($150–$300), and space maintainer ($200–$400).

The Child Dental Benefits Schedule

The Australian Government’s Child Dental Benefits Schedule (CDBS) provides up to $1,095.80 in dental benefits per eligible child over a consecutive two-year period. Eligible services include examinations, X-rays, fillings, extractions, and root canal treatment on baby teeth. Children aged 2 to 17 in families receiving certain government payments (such as Family Tax Benefit Part A) are eligible.

Many verified Townsville clinics bulk-bill CDBS patients — meaning no out-of-pocket cost for eligible families.

FAQ

Frequently asked questions

Is it worth filling a baby tooth that will fall out?

Yes. Baby teeth serve critical functions beyond chewing — they maintain space for permanent teeth, guide jaw development, and support speech development. Untreated decay in baby teeth causes pain, infection, and can spread to adjacent teeth. If a decayed baby tooth is lost prematurely, the surrounding teeth drift into the gap, potentially causing crowding and misalignment of the permanent teeth that follow. The Australian Dental Association recommends treating decay in baby teeth promptly to prevent these complications.

What happens if you don't fill a cavity in a baby tooth?

Untreated decay in a baby tooth progresses through the enamel into the softer dentine and eventually reaches the nerve (pulp). This progression causes increasing pain, potential abscess formation, facial swelling, and systemic infection. The infection can damage the developing permanent tooth bud sitting beneath the baby tooth, causing enamel defects or developmental disturbance. Premature loss of the baby tooth leads to space loss, which often results in more complex and expensive orthodontic treatment later.

How much does a filling in a baby tooth cost?

A filling in a baby tooth typically costs between $150 and $300 in Australia, depending on the size and location of the cavity and the material used. Children aged 2 to 17 who are eligible for the Child Dental Benefits Schedule (CDBS) may receive fillings at no out-of-pocket cost under the $1,095.80 two-year cap. Verified Townsville clinics bulk-bill eligible CDBS patients so families pay nothing for covered services.

At what age can a child get a dental filling?

Children can receive dental fillings as soon as decay is detected, regardless of age. Fillings have been successfully placed in children as young as 18 months when early childhood caries is present. The procedure is adapted to the child's age and cooperation level. For very young or anxious children, options include gentle techniques with tell-show-do behavioural management, nitrous oxide (happy gas) sedation, or in complex cases, treatment under general anaesthesia.

Are silver (amalgam) fillings safe for children?

Both amalgam and composite (tooth-coloured) fillings are considered safe for children by the Australian Dental Association and the World Health Organization. Verified Townsville clinics predominantly use composite resin fillings for children because they bond directly to tooth structure, require less tooth removal, and are more aesthetically pleasing. The choice of material depends on the location and size of the cavity and the child's ability to cooperate with the moisture-sensitive placement of composite.
