Teething in Babies: Everything You Need to Know

When babies turn three months old, they start producing more saliva and exploring the world with their mouths, but this doesn’t necessarily mean their first teeth are coming in.

The first tooth typically appears around six months of age, but it can also happen when the baby reaches a year old. Most children will have all their primary teeth by the age of three.

Teething in Babies by Age

6 – 12 months: The first 4 teeth start to emerge.

9 – 16 months: Baby may have the first 8 teeth.

13 – 19 months: Baby may have the first 12 teeth.

17 – 23 months: Baby may have the first 16 teeth.

12 – 33 months: Baby may have all 20 primary teeth.

The first teeth to appear are usually the two lower front teeth, also known as central incisors.

Four to eight weeks later, they are typically followed by the four upper front teeth (central and lateral incisors).

About a month later, the lower lateral incisors (the two teeth surrounding the lower front teeth) emerge.

Next come the first molars (the back teeth used for grinding food), followed by the canines (the pointed teeth in the upper jaw).

Most children will have all 20 primary teeth by their third birthday.

If your child’s teeth are coming in much slower than this, consult your doctor.

In rare cases, babies are born with one or two teeth or have a tooth emerge within the first few weeks of life. Unless the teeth interfere with feeding or are loose enough to pose a choking risk, it’s usually not a cause for concern.

You can help soothe your baby’s teething pain by massaging their gums with a clean finger.

3 Tips for Helping Your Baby Sleep Through the Night

Once the first tooth appears, you can start brushing it twice daily. It’s recommended to buy a baby toothbrush with soft bristles. Apply a small amount of baby toothpaste, about the size of a rice grain.

Additionally, when your baby’s first teeth come in, it’s a good idea to start giving them tap water daily, as it contains fluoride which helps prevent cavities by strengthening tooth enamel. Fluoride is usually not found in most bottled waters.

Discuss with your pediatrician if your child needs fluoride supplements.

Try to schedule the first dental check-up after the emergence of the first tooth, or by their first birthday.
