5 months (Typical: 4 to 7 months):
Teething begins. Your baby’s gums may be swollen and red where his new teeth are cutting through. It may be a bit painful for him, and he may dribble quite a bit. You’ll probably need to do a lot of comforting.
As soon as your baby’s first tooth comes through, you’ll need to get in the habit of tooth cleaning.
6 months (Typical: 5 to 7 months):
Your baby’s first teeth emerge, usually on the bottom in the middle (lower central incisors). These two teeth arrive at about the same time.
Tooth development is hereditary, so if you got your teeth early, it’s likely that your baby will, too.
7 months (Typical: 6 to 8 months)：
Upper middle teeth (The upper central incisors) emerge.
Once your baby is more than six months, try feeding him cold apple puree or yoghurt, straight from the fridge or silicone teethers, to give him some relief.
9 to 16 months (Typical: 9 to 12 months)：
Upper teeth right next to the middle teeth (upper lateral incisors) make their appearance. Bottom teeth right next to the middle teeth (lower lateral incisors) come next.
Teeth usually emerge in pairs, with two on the right and two on the left.
14 months (Typical: 12 to 15 months)：
The first molars come in on the bottom and the top at about the same time.
Primary teeth, or baby teeth, are brighter white and smaller than permanent teeth.
18 months (Typical: 16 to 22 months)：
The sharp, pointed teeth called the canine or cuspid teeth, emerge on the top and bottom.
26 months (Typical: 20 to 30 months)：
The very back teeth, or second molars, grow through the bottom gum.
26 months (Typical: 25 to 33 months)：
Your child’s second molars on the top come in soon after those on the bottom.
2 to 3 years：
Your child has a full set of 20 primary teeth, also known as baby teeth.
Your child’s jaw and facial bones grow, creating space between the primary teeth for the permanent, adult teeth to come in. Your child’s first teeth usually start to fall out at around the age of six or seven, and begin to be replaced by their permanent teeth.
