When do first molars come in?

First molars usually erupt after the front teeth and before the second molars. Many parents start searching about first molars eruption age around the second year of life, because these teeth are larger and can feel more intense than earlier teething stages. Timing can vary from child to child, so a baby first molars eruption may happen a little earlier or later and still be within a normal range. What matters most is the overall pattern of tooth eruption, your baby’s comfort, and whether symptoms fit a typical teething picture.

Common signs first molars are coming in

More chewing and gum pressure

Babies often chew on fingers, toys, or cups more when first molars are coming in. The gums in the back of the mouth may look swollen or feel firm.

Irritability, especially at night

First molars teething pain can seem stronger because molars are broader teeth. Some babies become clingier, wake more often, or seem harder to settle.

Changes in eating habits

A baby may prefer cold foods, refuse certain textures, or eat less for a short time if the back gums are sore during first molars eruption.

What the first molars teething timeline can look like

Early signs before you see a tooth

You may notice drooling, chewing, gum rubbing, or fussiness before anything is visible. This is often when parents wonder if first molars are about to come in.

One molar starts breaking through

A small white edge may appear, or you may feel a rough spot on the gum. First molars coming in baby stages can be gradual rather than all at once.

More than one molar erupts over time

First molars eruption order can vary. Some babies get upper and lower molars close together, while others have more spacing between each tooth.

How long do first molars take to erupt?

Parents often ask how long do first molars take to erupt because this stage can feel drawn out. Symptoms may come and go over days or weeks as the tooth moves under the gum and then breaks through. Once the tip appears, the rest of the tooth may continue emerging gradually. It’s common for first molars teething symptoms to be uneven, with better days and harder days rather than one steady pattern.

Ways to support your baby during first molars eruption

Offer safe pressure and cold comfort

A chilled teether, cool washcloth, or gentle gum massage can help ease pressure in the back gums where first molars teething pain is often felt.

Keep routines calm and flexible

Extra cuddling, simpler meals, and an earlier bedtime can help on tougher days. Some babies need more comfort while first molars are coming through.

Watch the pattern, not just one symptom

Looking at chewing, sleep changes, gum appearance, and appetite together can give a clearer picture of baby first molars eruption than any single sign alone.
