Tooth Development

When Will My Baby Start Getting Teeth?

Teething, the process of primary (baby) teeth coming through the gums into the mouth, is variable among individual babies. Some babies get their teeth early and some get them late. In general the first baby teeth are usually the lower front (anterior) teeth and usually begin erupting between the age of 6-8 months.

Although all 20 primary teeth usually appear by age 3, the pace and order of their eruption varies. Permanent teeth begin appearing around age 6, starting with the first molars and lower central incisors. This process continues until approximately age 21.

Why Are The Primary Teeth So Important?

It is very important to maintain the health of the primary teeth. Neglected cavities can and frequently do lead to problems which affect developing permanent teeth. Primary teeth, or baby teeth, are important for (1) providing space for the permanent teeth and guiding them into the correct position, and (2) permitting normal development of the jaw bones and muscles. While the front four teeth last until 6-7 years of age, the back teeth (cuspids and molars) aren’t replaced until age 10-13.
