Baby Teeth Care: Brushing, First Dentist Visit, and More
"They're just baby teeth, they'll fall out anyway." You'll hear this from well-meaning relatives. Ignore them. Baby teeth hold space for permanent teeth, affect speech development, and can cause serious pain and infection if they decay. Taking care of them from the start saves your child from preventable dental problems later.
Before Teeth Appear
Start oral care before the first tooth shows up. After feedings, wipe baby's gums with a clean, damp washcloth or gauze pad. This removes bacteria and gets baby used to having their mouth handled. It takes 10 seconds and you can do it during diaper changes.
When the First Tooth Arrives
Once you see that first little white nub poking through (usually around 6 months), it's time for a real toothbrush.
**Use a baby toothbrush** with a small head and extra-soft bristles. The Dr. Brown's Infant-to-Toddler Toothbrush ($4) or the MAM Baby's Brush ($5) are both good options. They have short handles that fit in your hand and small enough heads for tiny mouths.
**Use a rice-grain-sized smear of fluoride toothpaste.** The ADA now recommends fluoride toothpaste from the first tooth, not fluoride-free "training" toothpaste. Fluoride prevents cavities. The amount is so small (literally the size of a grain of rice) that swallowing it is safe.
How to Brush a Baby's Teeth
Sit baby in your lap, facing away from you, with their head resting against your chest. This gives you a clear view into their mouth and control of the toothbrush.
Brush all surfaces of each tooth: front, back, and chewing surface. Focus on the gum line where plaque collects. The whole process should take about 2 minutes. Do it twice a day, morning and before bed. The bedtime brushing is the more important one because saliva production drops during sleep, which means less natural protection against bacteria.
Making It Less Terrible
Babies and toddlers resist tooth brushing. Some scream. Some clamp their mouths shut. Some try to grab the brush. This is normal and you brush anyway. Their teeth need cleaning even if they don't enjoy it.
**Sing a song** to create a routine and mark the time (the ABCs twice is roughly 2 minutes). **Let them hold a second toothbrush** while you use the real one. **Use a mirror** so they can see what's happening. **Praise cooperation** when it happens.
If your toddler is in a full resistance phase, one parent can hold baby securely while the other brushes. It's not fun, but a few seconds of protest is better than cavities that require dental procedures under anesthesia.
The First Dentist Visit
The ADA and AAP both recommend a first dental visit by age 1 or within 6 months of the first tooth, whichever comes first. This visit is usually quick: the dentist looks at the teeth and gums, checks for any issues, and talks to you about care and diet. It also gets your child familiar with the dental office before they're old enough to be scared of it.
Look for a pediatric dentist rather than a general dentist. Pediatric dentists have extra training in child behavior and their offices are designed for kids (small chairs, fun decorations, TVs on the ceiling).
Foods That Help and Hurt
**Avoid:** Juice in bottles or sippy cups (the sugar bathes teeth constantly), sending baby to bed with a milk or juice bottle (causes "baby bottle tooth decay"), sticky snacks like fruit snacks and raisins that cling to teeth, and constant grazing (teeth need breaks from food contact).
**Good for teeth:** Water as the main drink after 6 months (especially fluoridated tap water), cheese and yogurt (calcium strengthens enamel), crunchy vegetables, and xylitol-sweetened items (xylitol actually inhibits cavity-causing bacteria).
When to Worry
Dark spots on teeth, visible holes, swollen or bleeding gums, persistent bad breath, or a tooth that looks grayish after a bump all warrant a dental visit. Catching issues early with baby teeth is much easier (and cheaper) than dealing with them later.
