Paediatric Dentistry: Preventing and Treating Tooth Decay in Children

Worried about those white spots on your child’s teeth? You’re not alone. Many parents feel overwhelmed trying to prevent tooth decay, especially when conflicting advice seems to be everywhere. At Kensington Dental Care, we’ve been helping families protect their children’s smiles for over three decades. We focus on prevention to help your child develop a lifetime of healthy habits (and fewer dental visits).

Understanding Tooth Decay in Children

Tooth decay happens when bacteria in your child’s mouth feed on sugars and create acid. Think of it like rust on a car – the acid slowly wears away the protective enamel coating. Children’s baby teeth are more vulnerable because their enamel is thinner and softer than adult teeth.

Baby teeth matter more than you might think, even though they’re temporary. They help your child eat properly, speak clearly, and guide permanent teeth into the right positions. Untreated decay can cause pain, affect speech development, and even impact school performance.

What Causes Tooth Decay in Children?

Three factors create the perfect environment for cavities:

Bacteria and Sugar: The bacteria mutans streptococcus feeds on dietary sugars, producing acids that attack enamel. This bacteria can be transmitted from adults to children through sharing utensils, testing food temperature with your mouth, or kissing on the lips.

Frequent Sugar Exposure: Regular snacking or sipping sugary drinks throughout the day gives bacteria constant fuel. The duration matters more than the amount. Grazing habits cause more damage than eating sweets at mealtimes.

Inadequate Fluoride and Hygiene: Insufficient fluoride exposure and irregular brushing allow decay to progress unchecked. Fluoride strengthens enamel and helps repair early damage.

Age-Specific Prevention Strategies

Prevention starts at birth. Here’s what to do at each stage:

0-12 Months

• Wipe gums with clean, damp cloth after feeds
• No fluoride needed yet

12-18 Months

• Use soft toothbrush with water, twice daily
• Water only (if using fluoridated tap water)

18 Months-6 Years

• Brush with small pea-sized low-fluoride children’s toothpaste
• Use age-appropriate fluoride paste

6+ Years

• Regular brushing with adult toothpaste
• Use pea-sized adult fluoride paste

First Dental Visit: Schedule your child’s first appointment by their first birthday or when their first tooth appears, whichever comes first. Early visits establish positive dental experiences and allow us to detect problems early.

Essential Prevention Tips

Dietary Recommendations:

• Limit sugary foods and drinks. Frequency matters more than quantity.
• Avoid settling babies with bottles containing milk or juice at night (lactose promotes decay-causing bacteria)
• Choose water or plain milk between meals
• Rinse with water after eating sweet foods

Daily Hygiene Habits:

• Brush twice daily—morning and before bed
• Supervise brushing until age 7-8
• Make it fun with songs, timers, or reward charts
• Floss once teeth touch each other

Monthly Lip Lift Checks: Look for early decay signs by lifting your child’s upper and lower lips. White spots near the gum line indicate early decay that can be reversed with professional care.

Professional Treatment Options

When prevention isn’t enough, we offer gentle, effective treatments at Kensington Dental Care:

Fluoride Treatments: Professional fluoride applications strengthen enamel and can prevent up to one-third of cavities. We apply concentrated fluoride varnish during routine visits.

Dental Sealants: Thin protective coatings applied to back teeth (molars) can prevent 80% of cavities for up to two years. Particularly effective since 90% of cavities occur in back teeth.

Fillings: When cavities develop, we use minimally invasive techniques to remove decay and restore the tooth. Our experienced team works at your child’s pace, using child-friendly language to ease anxiety.

Crowns: Severely decayed teeth may need small crowns to restore function and protect remaining tooth structure.

Special Considerations

Molar Hypomineralisation (Chalky Teeth): One in six Australian children develops this condition around age 6, where teeth lack healthy enamel and decay more easily. Look for chalky white, yellow, or brown patches on molars. If suspected, contact us on 08 8333 0885 for assessment.

Preventing Bacteria Transmission: Parents with high levels of decay-causing bacteria have a 50% chance of transmitting it to their children. Avoid sharing utensils, testing food with your mouth, or cleaning dummies in your mouth.

When to Seek Immediate Care

We know dental emergencies with children can be stressful. Our team is here to help even outside regular hours, you can contact us for guidance on what to do next.

Contact us immediately if your child experiences:

• Severe toothache that doesn’t respond to pain relief
• Facial swelling or lumps on the gums
• Knocked-out or broken teeth
• High fever with dental pain

For non-emergency concerns like white spots or sensitivity, schedule a routine appointment.
