Infant Tooth Eruption

A child's teeth actually start forming before birth. As early as 4 months of age, the primary or "baby" teeth push through the gums—the lower central incisors are first, then the upper central incisors. The remainder of the 20 primary teeth typically erupt by age 3, but the place and order varies.

Permanent teeth begin eruption around age 6, starting with the first molars and lower central incisors. This process continues until around age 21. Adults have 28 secondary (permanent) teeth—32 including the third molars (wisdom teeth).

Infant's New Teeth

The primary, or "baby," teeth play a crucial role in dental development. Without them, a child cannot chew food properly and has difficulty speaking clearly. Primary teeth are vital to development of the jaws and for guiding the permanent (secondary) teeth into place when they replace the primary teeth around age 6.

Since primary teeth guide the permanent teeth into place, infants with missing primary teeth or infants who prematurely lose primary teeth may require a space maintainer, a device used to hold the natural space open. Without a maintainer, the teeth can tilt toward the empty space and cause permanent teeth to come in crooked. Missing teeth should always be mentioned to your family dentist. The way your child cares for his/her primary teeth plays a critical role in how he/she treats the permanent teeth. Children and adults are equally susceptible to plaque and gum problems—hence, the need for regular care and dental checkups.

Preventing Baby Bottle Tooth Decay

Tooth decay in infants can be minimized or totally prevented by not allowing sleeping infants to breast or bottle-feed. Infants that need a bottle to comfortably fall asleep should be given a water-filled bottle or a pacifier. Our office is dedicated to fighting baby bottle tooth decay. Let us know if you notice any signs of decay or anything unusual in your child's mouth.

Thumb Sucking

Sucking is a natural reflex that relaxes and comforts babies and toddlers. Children usually cease thumb sucking when the permanent front teeth are ready to erupt. Typically, children stop between the ages of 2 and 4 years. Thumb sucking that persists beyond the eruption of primary teeth can cause improper growth of the mouth and misalignment of the teeth. If you notice prolonged and/or vigorous thumb sucking behavior in your child, talk to your dentist.

Here are some ways to help your child outgrow thumb sucking:

  • Don't scold a child when they exhibit thumb sucking behavior; instead, praise them when they don't thumb suck.
  • Focus on eliminating the cause of anxiety—thumb sucking is a comfort device that helps children cope with stress or discomfort.
  • Praise them when they refrain from the habit during difficult periods.
  • Place a bandage on the thumb or a sock on their hand at night.
