A Guide to Promote Healthy Toddler Teeth and Prevent Decay
With insights from MissPoppins expert: Nicole Morales
Caring for your child’s teeth early on is essential for their overall health. Establishing baby teeth care habits can prevent baby bottle tooth decay, strengthen enamel, and set the stage for lifelong healthy smiles. Dental care is typically the origins of general healthy outcomes; and during toddlerhood, it is just that much more primordial.
Some of the most common concerns include the efficacy of toothpaste safety for toddlers, proper age guidelines, and tips to begin establishing these healthy brushing habits.
Why Fluoride Matters for Baby Teeth and Toddler Dental Health
Fluoride is a natural mineral found in water and certain foods that strengthens enamel and prevents cavities. It works by protecting teeth from acids caused by bacteria and sugars, and it can even reverse early signs of decay. Although conversations have risen over the years on the safety of fluoride, dental professionals still consider it safe to use for children, toddlers, and pregnant women.
When used in age-appropriate amounts, fluoride is safe to use for adults, children, and pregnant individuals. For infants, this means a tiny, rice-sized smear of fluoride toothpaste once teeth start appearing. Likewise, is fluoride safe for pregnant women? Fluoride in toothpaste and community water is considered safe during pregnancy, and keeping your teeth healthy benefits both you and your baby.
Incorporating fluoride into your child’s daily routine is one of the best ways to prevent baby bottle tooth decay and keep their smile strong. According to the ADA, fluoride works by remineralizing enamel, making teeth more resistant to acid attacks from bacteria and sugars, helping stop cavities before they start.

Studies show that community water fluoridation reduces tooth decay by about 25% in both children and adults compared to non‑fluoridated areas.
Can Toddlers Use Adult Toothpaste?
No. What makes adult toothpaste unsafe for toddlers is the higher fluoride amount, harsher taste for picky toddlers, and abrasive ingredients.
For such a young enamel, fluoride can cause fluorosis, a cosmetic defect on tooth enamel (Colgate, 2024). Toothpaste often contains active ingredients like sodium lauryl sulfate (SLS), triclosan, artificial sweeteners, and additives like titanium dioxide. While these components are safe when used topically on teeth, swallowing large amounts is not advised because ingestion increases total fluoride intake and can raise the risk of toxicity or adverse effects, particularly in vulnerable groups like young children who are more likely to swallow toothpaste instead of spitting it out. Healthcare providers emphasize age‑appropriate toothpaste use and supervision, especially for toddlers(Petrović et al., 2023).
When to Start Brushing Your Baby’s Teeth
Brushing should begin as soon as your baby’s first two teeth appear, usually around 6 months. Use a soft-bristled toothbrush with a small amount of fluoride toothpaste. Brush twice daily, especially before bedtime, for at least two minutes to remove plaque and food residue.
If your baby hasn’t sprouted teeth yet, gently wipe their gums with a clean, damp cloth after feedings. This simple step keeps the mouth clean and prepares them for brushing once teeth emerge. Silicone toothbrushes for baby are recommended during this stage and can be readily found on the MissPoppins storefront.
Toddler Toothbrushing Guide: Ages 0–6+
Babies and Toddlers (0–3 years)
Use a rice-sized amount of fluoride toothpaste (or fluoride-free if preferred).
Make brushing part of your daily routine to prevent cavities from an early age.
Children (3–5 years)
Use a pea-sized amount of toothpaste.
Supervise brushing so children learn to spit out toothpaste rather than swallow it.
Older Children (6+ years)
Encourage independent brushing and spitting.
Make brushing fun with songs, timers, or small rewards to reinforce the habit.
Tips to Avoid Baby Bottle Tooth Decay
Avoid letting your baby fall asleep with milk, formula, or juice bottles, which can cause baby bottle tooth decay.
Offer a balanced diet and limit sugary snacks to support strong teeth.
Schedule your child’s first dental visit by their first birthday to catch issues early and establish comfort with dental care.
Building Lifelong Healthy Teeth Habits
It is recommended to continue helping your child brush their teeth until they are around 6 or 7 years old. By this age, they have better coordination and emotional maturity to pick up healthier habits.
Ensure you teach your child to properly brush and spit the toothpaste out after use. Although an occasional slip-up is fine, you should not swallow your toothpaste.
