Baby Dental Care: How to Care for Your Baby's First Teeth

Why Baby Teeth Matter

Many parents assume that because baby teeth fall out, they don't really matter. But primary (baby) teeth are critical for chewing, speech development, and holding space in the jaw for permanent teeth. Early tooth decay can cause pain, infection, and crowding problems in permanent teeth that emerge years later.

Dental habits formed in infancy also set the tone for oral health throughout childhood and beyond. Starting a consistent brushing routine early — even before it seems necessary — pays dividends for years.

Before the First Tooth: Gum Care

You can (and should) start oral hygiene before any teeth appear. After each feeding, wrap a clean, damp washcloth or gauze around your finger and gently wipe the gums. This removes milk residue and bacteria, and — importantly — gets your baby used to having their mouth touched, which makes brushing much easier when teeth arrive.

After the First Tooth: Brushing

The moment the first tooth erupts — usually around 6 months — it's time to start brushing. Use a small, soft-bristled infant toothbrush and a rice grain-sized smear of fluoride toothpaste. Brush in gentle, circular motions, covering all surfaces of the tooth and along the gumline.

• Brush twice a day, aiming for 2 minutes each time
• Make it fun — sing a song, use a timer, or watch a short brushing video together
• Let your baby hold the toothbrush too — they'll learn by imitation
• Always do a "parent's turn" to make sure teeth are thoroughly cleaned

Toothpaste: When and How Much?

Fluoride toothpaste is the most effective protection against cavities available for young children. Current guidelines from the American Dental Association (ADA) and the American Academy of Pediatrics (AAP) are clear:

• Under 3 years: Use a smear the size of a rice grain (approx. 0.1 g) of fluoride toothpaste
• Ages 3–6: Use a pea-sized amount (approx. 0.25 g) of fluoride toothpaste
• At these amounts, accidental swallowing is safe — no need to wait until your child can spit
• "Fluoride-free" baby toothpastes do not protect against cavities; fluoride is the key ingredient

The First Dentist Visit

The American Academy of Pediatric Dentistry (AAPD) recommends a child's first dental visit within 6 months of the first tooth erupting, or by the first birthday — whichever comes first. This visit is usually brief and focused on assessment rather than treatment. The real value is normalizing the experience early: children who visit the dentist as babies are far less likely to develop dental anxiety later.

Your pediatrician can also check teeth at regular well-child visits and apply fluoride varnish as early as 6 months old, which provides extra protection during the cavity-prone toddler years.
