Baby Teeth at 1 Year: How Many Your Baby Should Have and What Order They Come In
If you’re wondering how many baby teeth a 1-year-old should have, the answer is simple: by 12 months most children have between 4 and 8 teeth, although a healthy baby may have just one or none. Teething is the process by which the 20 primary teeth come through, usually between 6 months and 3 years. So your child’s own pace matters far more than the exact number.
Quick summary
- At 12 months, 4-8 teeth is typical: the upper and lower central incisors and often a lateral incisor.
- The first to appear are usually the lower central incisors, around 6-10 months.
- Discomfort tends to peak in the days before a tooth breaks through the gum and fades shortly after.
- If no tooth has appeared by 18 months, check in with your pediatrician or pediatric dentist.
How to tell a tooth is coming
You’ll know a tooth is on its way when your baby drools more than usual, chews on everything they can reach, and you notice a whitish or reddened bump on the gum. Many babies also rub a cheek or tug an ear on the same side.
- Heavy drooling and small red patches on the chin from the moisture.
- Constant urge to chew: toys, fingers, the edge of the crib.
- Swollen gums and sometimes a small white spot just before the tooth appears.
- More irritability and night waking for a few days.
- Temporary refusal of the spoon or the breast because pressure is uncomfortable.
However, teething doesn’t explain everything. High fever, diarrhea or vomiting are not symptoms of teething, so in those cases call your pediatrician rather than blaming the tooth.
Does a tooth coming in hurt?
Yes, a tooth breaking through usually causes real discomfort, although it varies a lot from child to child. Some babies get through teething with barely a fuss, while others have hard nights. A pain that lasts for weeks without a break, however, is not normal.
Pressure and cold help most. Massage the gum with a clean finger for a minute, or offer a teether that has been kept in the fridge (not the freezer, which can make it too hard and damage the gum). A clean, damp, cold cloth also works. If your baby already eats solids, a piece of cold fruit offered while sitting with you can help considerably. Avoid home remedies unless you’ve discussed them with your pediatrician first, since they should be the ones to advise on any pain relief.
That said, there are two things to avoid altogether: numbing gels for the gums that contain benzocaine or lidocaine, and teething necklaces, whether they’re made of amber, wood or silicone. The American Academy of Pediatrics advises against both because they can be dangerous for babies. The US Food and Drug Administration also says these gels should not be used for teething, and it has received reports of deaths and serious injuries from strangulation and choking caused by teething jewelry.
From a Montessori perspective, emotional support matters as much as physical relief. Name what’s happening calmly (“your mouth feels uncomfortable, here is something cold to chew”) and leave the teether in a low basket so they can reach it themselves. That way they learn they have their own ways of soothing themselves.
What baby teeth at 1 year you can expect
By the first birthday, the most common picture is the four central incisors (two top, two bottom) and, in many cases, one or more lateral incisors. Baby teeth at 1 year are almost always incisors, because the molars and canines come later. However, the normal range is wide: some children have 10 teeth at 12 months and others still have none.
The months-minus-six rule
Pediatricians often use a rough guide: age in months minus six gives the approximate number of teeth, and it works up to two years of age. At 12 months, that gives about six teeth. It’s a reference, not a test. So being a few teeth above or below is within the expected range.
Common mistake: comparing baby teeth at 1 year at the park
Imagine a family who has just moved to Sotogrande. Their 13-month-old daughter still has no teeth, and at the park she meets a 10-month-old who already shows six. The mother starts checking her daughter’s mouth every morning and searching online for vitamins. The mistake is using baby teeth at 1 year as a measure of development. When teeth come in depends mostly on family inheritance and says nothing about how your child crawls, talks or eats.
The solution is to look at your own child’s trajectory and ask relatives when you each got your teeth. Also keep the cut-off in mind: if no tooth has appeared by 18 months, book an appointment with your pediatrician or a pediatric dentist to have it checked.
How long a tooth takes to break through the gum
A concrete example: your 10-month-old has been waking at two in the morning for three nights and bites the spoon hard. On the fifth day, when you run a finger along the upper gum, you feel a rough edge: the lateral incisor. Two nights later, sleep returns to its usual routine.
That pattern (a few difficult days, then back to normal) is typical. If discomfort goes on for more than a week or two with no visible change in the gum, it’s probably not the tooth, and it’s worth getting it checked.
When baby teeth come in: a rough timeline
Baby teeth come in a fairly predictable order, starting around 6 months and finishing between 2 and 3 years. This timeline, based on the references pediatricians use, can help you place where your child is:
- Lower central incisors: 6-10 months.
- Upper central incisors: 8-12 months.
- Upper lateral incisors: 9-13 months.
- Lower lateral incisors: 10-16 months.
- First molars: 13-19 months.
- Canines (eye teeth): 16-23 months.
- Second molars: 23-33 months.
Notice that the first molars appear after the first birthday. That’s why baby teeth at 1 year rarely include molars, and your child still mashes food with their gums. Offer soft textures and pieces they can easily squash. Molars also tend to be more uncomfortable because of their size, so expect a patch of irregular sleep somewhere between 13 and 19 months.
Caring for baby teeth from the very first tooth
Care starts as soon as the first tooth appears: brushing twice a day and a first dental visit around the first birthday. The American Academy of Pediatrics recommends fluoride toothpaste in an amount the size of a grain of rice until age 3. Confirm this with your pediatrician, who will tailor the routine to your child.
Here the Montessori approach offers a lot. In a prepared environment, the toothbrush lives in a cup at the child’s height, next to a low mirror, and tooth care becomes part of practical life. From 12-15 months your child can hold the brush and try first, and then you gently go over it. That sequence (I try, you help me) reduces bathtime battles. It also fits the idea of autonomy championed by the Association Montessori Internationale from the earliest years.
Frequently asked questions
How do I know if my baby is starting to teethe?
The clearest signs that teething is starting are heavy drooling, a constant urge to chew, swollen gums or a small white spot, and some irritability for a few days, especially at night, although every baby expresses it differently. If there is high fever or diarrhea, consult your pediatrician.
Does teething hurt?
Teething usually causes moderate discomfort that concentrates in the days before a tooth breaks through the gum and fades soon after, although intensity varies a lot from baby to baby. Cold, gentle pressure on the gum and your calm presence are the best relief. Any medication should be prescribed by your pediatrician.
How many teeth should a 1-year-old have?
A 1-year-old usually has between 4 and 8 teeth, almost always the upper and lower central incisors and sometimes some laterals, although having fewer teeth or none can also be normal at that age. What matters is that they keep appearing over time. If none has come through by 18 months, ask for an assessment.
How long does it take for a tooth to break through the gum?
A tooth usually breaks through the gum within a few days of the discomfort starting, and the most intense symptoms cluster from about four days before to three days after it appears, so the difficult phase lasts roughly a week. After that the tooth keeps growing for weeks without causing much pain.
This week, prepare a small basket with two cold teethers and a brush at your child’s height, and mark each new tooth’s date on the calendar so you arrive at the next pediatric check-up with real data. And if you’re looking for a school that supports these early years with the same calm, book a personalised school visit and discover our Montessori Nido in Sotogrande.
