What is a typical teething schedule for babies?

Babies begin to teethe between ages 4 and 7 months when the two lower central incisors begin to break through the gums. Signs that the teething process is about to begin includes swollen gums and excess drooling.

The teething schedule for babies includes the emergence of the upper central incisors between ages 8 and 12 months, the top and bottom teeth next to the incisors between ages 9 and 16 months, and the canine teeth between ages 16 and 23 months. The teething schedule for toddlers begins with the bottom second molars at 23 months and the top second molars at 25 months. By the age of 3, most children have full sets of 20 primary teeth.
