Oral health isn’t just for grown-ups—it starts long before your child’s first tooth ever appears. Early dental care plays a critical role in preventing cavities, setting up lifelong healthy habits, and ensuring those little smiles develop properly.
The Academy of General Dentistry and the American Academy of Pediatric Dentistry (AAPD) emphasize that dental care should begin in infancy—well before the first tooth erupts. From gum cleaning routines to the first dental visit, every step matters.
Here’s everything parents need to know to protect their child’s smile from day one.
Infant Oral Care: Before the First Tooth
Even before teeth appear, bacteria can cling to gums. Good oral care habits should begin early:
Avoid bedtime bottles with milk, juice, or sweetened drinks. Saliva production slows during sleep, which means sugars linger on the gums and teeth, fueling cavity-causing bacteria .
Use only water if a bottle is necessary.
Wipe gums gently after feedings. A soft, damp cloth can keep gums clean and get your child used to oral care.
👉 Did you know? Some babies get teeth as early as 3 months, though most will see their first tooth around 6 months. The latest arrivals may not appear until 15 months .
Brushing Basics for Babies and Toddlers
When teeth do arrive, they need protection right away.
First teeth: Use a soft, flexible children’s toothbrush and a tiny smear of fluoride toothpaste (about the size of a grain of rice).
At age 2: Switch to a pea-sized amount of fluoride toothpaste .
Parental assistance: Children should not brush alone until ages 7–9, since studies show they leave significantly more plaque behind when unsupervised .
Discuss habits such as thumb sucking or pacifier use.
Teach parents proper home care techniques.
Provide guidance on injury prevention.
Offer preventive or restorative treatment if necessary.
Early visits also build trust and comfort for your child, helping them feel safe in a dental environment.
Risk Factors for Cavities in Children
Some children are more prone to cavities due to genetic, environmental, or behavioral factors. Key risks include:
Maternal illness or poor prenatal nutrition.
Frequent bottle use at bedtime or prolonged sippy cup use.
High consumption of sugary snacks and drinks.
Poor oral hygiene routines.
Deep grooves and pits in teeth that trap bacteria .
Preventing Cavities: Best Practices
Parents can take simple, proactive steps to protect their child’s smile:
Limit sugary snacks and drinks. Encourage water instead of juice or soda.
Rinse with water after eating when brushing isn’t possible.
Assist with brushing until your child is at least 7–9 years old.
Use fluoride toothpaste and rinses as directed by your dentist.
Schedule regular dental visits every 6 months (or as recommended).
Consider dental sealants. Sealants protect the grooves of back teeth—the most common sites for cavities in kids .

A Note for Parents
Children learn by example—so your attitude toward dental visits matters. Avoid sharing negative dental stories with your kids, as this can create unnecessary fear or trauma. Instead, talk about dental visits positively, focusing on keeping smiles strong and healthy.
