Tooth Eruption Charts

Babies start teething as early as six months of age. Some kids may show late eruption, and some may show even earlier than six months. And then there is a term called natal teeth, in which babies are born with the two front teeth called canines.

Tooth eruption in the kids continues to 12-14 years of life and the period of appearance of permanent teeth overlaps eruption of milk teeth. There are obviously exceptions and some variations are quite normal.

How is a tooth eruption chart helpful?

Kids’ tooth eruption chart helps the parents to know if their kid is growing according to the milestones or not. If the baby is not showing teething in time or some erupted tooth has got some abnormal features, parents can rush to the dentist in time so that the dental issues of your kids are solved before they arise.


Tooth eruption chart tells us which pair of the tooth comes at which age and what the characteristics of the teeth are. Let’s have a look at the tooth eruption chart and how it is interpreted.

Central incisors

Central incisors are the first teeth to appear in a baby’s oral cavity. They are centrally located, and usually lower incisors appear before the upper pair of incisors.

Primary incisors or milk teeth appear at the age of 6 to 12 months and they are replaced by permanent incisors at 6-7 years of age. There are 2 pairs of central incisors in our oral cavity.

Lateral incisors

Lateral incisors are also two in number for each jaw. They are present just lateral to the central incisors. Primary incisors appear at the age of 9 to 12 months and are replaces by the permanent teeth at around eight years of age.


They are also known as canines. They are a bit sharp and pointed teeth present lateral to the lateral incisors. Two pairs of cuspids one in each jaw is present laterally. They are not as developed or pointed as they are in carnivorous animals like cats and dogs, but they are sharp enough to help humans eat any kind of food especially meat. Primary cuspids appear in 16-22 months of age. Permanent cuspids replace them at 12 years.


Bicuspids are also called as premolars. Two pairs of bicuspids are present which appear at the age of 2-4 years if they are primary. When the child reaches age 10-12 years, permanent premolars take the place of primary bicuspids.


Molars are also two pairs of teeth which are present lateral to the premolars. They are larger in size and do not appear as milk teeth. Only permanent form of premolars exists which appear at the age of 6-13 years in a child.

Wisdom teeth

They appear at the end of all the teeth. Primary eruption does not exist and permanent teeth appear at the age of 17-21 years. Some people find it appearing at an age of 25 years. So variations are always there.
