Learn when to start brushing your baby's teeth, how to choose a first toothbrush, and build a healthy oral care routine from day one.
Quick answer
Start brushing as soon as the first tooth appears — usually around 6 months. Use a soft-bristled baby toothbrush with a tiny smear of fluoride toothpaste (no more than a grain of rice).
Why early brushing matters
Baby teeth are temporary, but they play a big role in chewing, speech development, and holding space for adult teeth. Decay can start as soon as a tooth erupts, so don't wait until your child has a full set of teeth to begin cleaning.
Starting early also helps your baby get used to the sensation of brushing, making toddler years much easier.
Choosing the right toothbrush for each stage
For a baby's first teeth (0–12 months), look for a brush with an extra-small head and very soft bristles. A long handle helps you reach and control the brush comfortably. The brush-baby First Brush Pack of 2 is designed exactly for this stage: soft bristles for delicate gums and a long handle for parent control.
For toddlers (1–4 years), a brush like Dr. Brown's Toddler Toothbrush Dinosaur offers a slightly larger head and a chunky grip that little hands can hold while you still guide the brushing. The soft bristles remain gentle on growing teeth and gums.
Once your child is around 3 years old and excited about brushing, a themed brush such as the Paw Patrol Toothbrushes & Caps Pack of 2 can make the routine more fun. The protective caps keep brush heads clean between uses.
Common mistake: using too much toothpaste
It's easy to think more toothpaste means cleaner teeth, but for babies and toddlers, a tiny amount is all you need. Too much fluoride can cause white spots on developing teeth. Stick to a smear (rice-grain size) until age 3, then a pea-sized amount from ages 3 to 6.
Step-by-step baby oral care routine
- Start at first tooth: As soon as the first tooth appears (usually around 6 months), brush twice a day with a soft-bristled baby toothbrush and a rice-grain-sized smear of fluoride toothpaste. Common mistake: waiting until multiple teeth appear. Decay can start on the very first tooth.
- Use the right amount of toothpaste: For babies under 3 years, use a smear no larger than a grain of rice. For children 3–6 years, use a pea-sized amount. Teach your child to spit out the toothpaste after brushing, not swallow it. Checkpoint: if your child swallows toothpaste, reduce the amount further or switch to a fluoride-free training toothpaste until they learn to spit.
- Brush for two minutes, twice a day: Set a timer or use a fun two-minute song. Brush all surfaces of each tooth gently in small circles. Pay extra attention to the gum line where plaque hides. Common mistake: brushing too hard or too fast. Gentle circular motions are more effective than vigorous scrubbing.
- Replace the toothbrush every 3 months: Bristles wear out and become less effective. Replace sooner if bristles are frayed or after your child has been sick. A toothbrush with a protective cap (like the Paw Patrol set) helps keep the head clean between uses. Set a calendar reminder every 3 months so you don't forget.
- Make it fun and consistent: Let your child choose their toothbrush (character-themed options like Paw Patrol can help). Brush together as a family, use a sticker chart, or read a tooth-brushing book. Consistency builds a lifelong habit. If your child resists, try a different toothbrush texture or flavor of toothpaste — sometimes a small change makes a big difference.
