Most 12-month-olds have between two and eight teeth, with six being a common number at the first birthday. That range is wide because tooth eruption timing varies significantly from child to child. Some babies get their first tooth at four months, others not until after their first birthday, and both can be perfectly normal.
What to Expect at 12 Months
Baby teeth typically start appearing around six months of age, beginning with the two lower front teeth (central incisors). The two upper front teeth usually follow within a couple of months. By 12 months, many children also have their upper and lower lateral incisors, the teeth flanking the front two on each side.
That gives a rough total of four to eight teeth for most one-year-olds, though having fewer is common and rarely a concern. Children are born with a full set of 20 primary teeth hidden beneath the gums, and these emerge on their own schedule over the next two years or so. The complete set of 20 baby teeth is usually in place by age three.
The Typical Eruption Order
While exact timing shifts from child to child, the sequence teeth appear in is fairly consistent:
- 6 to 10 months: Lower central incisors (bottom front two)
- 8 to 12 months: Upper central incisors (top front two)
- 9 to 13 months: Upper lateral incisors (beside the top front teeth)
- 10 to 16 months: Lower lateral incisors (beside the bottom front teeth)
- 13 to 19 months: First molars
- 16 to 23 months: Canines (the pointed teeth)
- 23 to 33 months: Second molars
Notice how much those ranges overlap. A 12-month-old with only two teeth is still within the normal window for most tooth types. The order matters more than the exact age each tooth shows up.
When Fewer Teeth Might Be a Concern
If your child hasn’t developed any teeth by nine months of age, it’s worth bringing up with your pediatrician. That doesn’t necessarily mean something is wrong. Genetics play a large role in eruption timing, and late teethers often catch up quickly once the process starts. But a professional can check for underlying issues like nutritional factors or, very rarely, conditions that affect tooth formation.
A family pattern of late teething is one of the most common explanations. If you or your partner were late getting your first teeth, your child may follow the same timeline. Premature babies also tend to teethe later, adjusted for their earlier birth date.
Teething Signs Around 12 Months
If your one-year-old is still actively cutting teeth, you may notice drooling, fussiness, and a strong urge to chew on everything in reach. Swollen or tender gums right where a tooth is pushing through are normal.
One thing teething does not cause is a true fever. It can nudge your child’s body temperature slightly above the typical 98.6°F, but it won’t reach 100.4°F or higher. A temperature at or above that threshold points to something else, like an infection, and shouldn’t be chalked up to teething.
Caring for Those First Teeth
Even if your child only has a couple of teeth, daily cleaning matters. As soon as the first tooth appears, brush it twice a day with a soft, child-sized toothbrush and a smear of fluoride toothpaste about the size of a grain of rice. That tiny amount is safe to swallow and effective at protecting new enamel.
Before any teeth come in, you can wipe your baby’s gums after feedings with a clean, damp gauze pad or washcloth. This removes bacteria and gets your child used to the routine early.
Preventing Early Tooth Decay
Baby teeth are especially vulnerable to decay, and one of the biggest risk factors at this age is what happens at bedtime. Letting a child fall asleep with a bottle of milk, formula, or juice allows sugars to pool around the teeth for hours. The recommendation is simple: finish bottles before going to bed, not during sleep.
Other steps that protect new teeth around the one-year mark:
- Limit bottle contents to formula, breast milk, or milk. Avoid juice, sugar water, or soft drinks in bottles.
- Start transitioning to a cup by the first birthday. Sipping from a cup reduces the prolonged sugar contact that bottles create.
- Skip sugar or honey on pacifiers. A clean pacifier is fine, but coating it in sweeteners invites decay.
The First Dental Visit
Current guidelines recommend scheduling your child’s first dental visit by their first birthday, or within six months of the first tooth appearing, whichever comes first. This visit is usually quick and low-key. The dentist checks for early signs of decay, looks at how the teeth and jaw are developing, and gives you guidance on brushing and diet specific to your child. Starting dental visits early also helps your child become comfortable in the chair before any treatment is ever needed.
