The habits a child develops in their first few years of life often determine their dental health for decades. Good oral hygiene practices established early — combined with regular professional dental care — can protect your child from painful decay, expensive treatments, and a lifetime of dental anxiety.
When Should a Child First Visit the Dentist?
Australian Dental Association guidelines recommend a child’s first dental visit at age one, or when their first tooth appears — whichever comes first. We know this seems early, but these first visits are gentle, reassuring appointments — not treatments. The goal is to familiarise your child with the dental environment, assess developing teeth, and give parents advice on diet, fluoride and home care before problems develop.
Children who visit the dentist from an early age are significantly less likely to develop dental anxiety as adults. The dental clinic becomes a normal, familiar part of life — not a scary unknown.
Teaching Children to Brush — What Actually Works
Most parents start their child on tooth brushing around age one, as soon as teeth appear. Here are the evidence-based recommendations:
- Use a small, soft-bristled toothbrush designed for children, replaced every 3 months
- Fluoride toothpaste — use a rice-grain amount for children under 18 months, a pea-sized amount for 18 months to 6 years
- Brush twice daily — morning and before bed, for a full two minutes each time
- Supervise brushing until age 8 — children lack the manual dexterity to brush effectively on their own before this age
- Make brushing fun — use a timer, play a song, or use an app to keep children engaged for the full two minutes
Diet and Dental Health
Sugar is the primary driver of childhood dental decay. But it is not just the quantity of sugar that matters — it is the frequency of exposure. Every time your child consumes sugar, the bacteria in plaque produce acid that attacks tooth enamel for up to 30 minutes. Frequent snacking on sweet foods and drinks means the teeth are under acid attack almost continuously.
Practical steps include limiting sugary snacks to mealtimes, replacing sugary drinks with water (especially fluoridated tap water), and never putting a child to bed with a bottle containing anything other than water.
Fissure Sealants — Protection for Back Teeth
The deep grooves on the biting surfaces of back teeth are the most common sites for childhood decay — and the hardest to clean. Fissure sealants are a protective coating applied to these grooves as soon as the permanent molars erupt (typically around age 6–7 and 11–12). They dramatically reduce decay risk in these vulnerable areas and are a standard part of our preventive care for children at Peninsula Dental Clinic.
