Two-and-a-Half to Three Years Old

The Temporary central incisors are pushed out and replaced by permanent incisors at about two-and-a-half years.

The permanent teeth are easy to spot because they are longer, wider, and often more yellow in color than the milk teeth.

At around this time, two of the permanent molar teeth appear on each side of the top and bottom jaw.

Three-and-a-Half Years Old
The Lateral incisors are also temporary, replaced by permanent incisors, and a further two permanent molars appear on each side of the top and bottom jaw.
