Most 10-month-olds have about two to four teeth, though some have more and others still have none. A common rule of thumb is that babies get roughly four teeth for every six months of life, which puts a 10-month-old right around that two-to-four range. But tooth eruption varies widely from child to child, and the timing says nothing about your baby’s overall health or development.
Which Teeth Come In First
The two bottom front teeth (lower central incisors) almost always lead the way, typically appearing between 6 and 10 months. The two upper front teeth follow, usually between 8 and 12 months. So at 10 months, a baby who’s right on schedule might have two bottom teeth that are well established and two upper teeth just breaking through.
After those four front teeth, the next to arrive are the upper lateral incisors (the teeth flanking the top front two), which tend to show up between 9 and 13 months. The lower lateral incisors come a bit later, around 10 to 16 months. A 10-month-old with six teeth is perfectly normal, and so is one with just two. The ranges overlap significantly.
What If Your Baby Has No Teeth Yet
Some babies don’t get their first tooth until after their first birthday, and that’s still within the normal window. The lower central incisors can appear as late as 10 months on the standard timeline, meaning a 10-month-old with zero teeth isn’t necessarily behind. Genetics play a big role: if you or your partner were late teethers, your baby likely will be too.
Dental guidelines recommend that children have their first dental checkup within six months of their first tooth erupting, and no later than 12 months of age. If your baby reaches their first birthday with no teeth at all, that visit is a good time to ask about it. In the vast majority of cases, the teeth are simply taking their time.
Teething Symptoms to Expect
A prospective study tracking nearly 500 tooth eruptions found that teething symptoms cluster in a narrow window: about four days before a tooth breaks through, the day it appears, and three days after. That’s roughly an eight-day stretch per tooth. Outside that window, symptoms tend to fade.
The symptoms most closely linked to teething include increased drooling, biting on objects, gum rubbing, irritability, wakefulness, ear rubbing, a facial rash (from all that drool), and a slight decrease in appetite for solid foods. A mild rise in temperature can happen, but actual fever over 102°F was not associated with teething in the study. No single symptom appeared in more than 35% of teething babies, so your child may breeze through with barely a fuss or have a rough few days for each tooth.
Vomiting, high fever, persistent cough, and rashes on other parts of the body are not teething symptoms. If your baby has those, something else is going on.
Safe Ways to Ease Teething Pain
The simplest relief is also the most effective: gently rub your baby’s gums with a clean finger, or offer a firm rubber teething ring to chew on. The teething ring should not be frozen solid, since a very hard surface can actually bruise tender gums. A chilled (not frozen) ring or a cold, wet washcloth works well.
Avoid numbing gels containing benzocaine or lidocaine. The FDA has warned that benzocaine can cause a rare but serious condition that reduces the blood’s ability to carry oxygen, and lidocaine solutions have been linked to heart problems and severe brain injury in young children. Amber teething necklaces and similar jewelry also carry real risks of strangulation and choking, and the FDA has received reports of infant deaths from these products.
Caring for New Teeth
Start brushing as soon as the first tooth appears. Use a soft-bristled infant toothbrush with a smear of fluoride toothpaste no bigger than a grain of rice. Brush twice a day, and after the nighttime brushing, avoid giving your baby anything other than water. If you’re unsure about using fluoride toothpaste before age 2, your baby’s dentist or pediatrician can help you weigh the benefits for your child’s specific situation.
Those new teeth are vulnerable to decay right away. Putting a baby to bed with a bottle of milk, formula, or juice lets sugary liquid pool around the teeth for hours. The same goes for prolonged sipping from a bottle or sippy cup during the day. Water is fine anytime, but other drinks should be finished in a reasonable sitting rather than carried around.
The Full Baby Teeth Timeline
Your baby will eventually get 20 primary teeth. Here’s the general order after those first front teeth:
- Upper and lower central incisors: 6 to 12 months
- Upper and lower lateral incisors: 9 to 16 months
- First molars: around 13 to 19 months
- Canines (the pointed teeth): around 16 to 23 months
- Second molars: around 23 to 33 months
Most children have their full set of 20 baby teeth by age 3. The sequence matters more than the exact timing. Teeth that arrive a few months “late” but follow the expected order are completely normal.
