Baby Teething Timeline

Teething is a rite of passage for every little one and involves the movement of milk teeth (also known as baby teeth, primary teeth, or deciduous teeth) in and then through the gums.

Unfortunately, it can be painful for babies and, in turn, stressful for their parents and caregivers. To help you understand more about the teething timeline, we've created this guide to all things teething.

When do babies start teething?

All babies start teething at different times. For some, teeth can start to appear as early as three months, while others don’t start teething until after their first birthday. But most babies will start showing symptoms of teething when they’re around six months old, with the bottom, front teeth appearing first.

Here’s a rough guide to how a baby’s teeth emerge...

  • Bottom incisors (bottom front teeth): These are usually the first teeth to appear, usually at around six to 10 months.
  • Top incisors (top front teeth): These usually come through from about eight to 12 months.
  • Top lateral incisors (either side of the top front teeth): These appear at around nine to 13 months.
  • Bottom lateral incisors (either side of the bottom front teeth): These come through at around 10 to 16 months.
  • First Molars (back teeth): These come through at around 13 to 19 months.
  • Canines (often known as the ‘fang’ or ‘eye tooth’): These come through at around 16 to 23 months.
  • Second Molars: These come through at around 20 to 30 months.

Most little ones will have all 20 of their milk teeth by the time they're around three years old.

How many teeth will my little one have?

By the time they've stopped teething, children have 20 milk teeth in total. That’s 10 on the top, and 10 on the bottom.

When do children's milk teeth start falling out?

Children's milk teeth usually will begin to fall out around the age of six or seven to make way for their permanent adult teeth – of which there will be 32!
