The Lowdown on Baby Teeth

Cleanings & Prevention Nashua NHFor 27 years we’ve been proud to be the best family dentistry in Nashua. From generation to generation, there’s one thing we love to see — parents passing on good home hygiene habits to their children. After all, we provide the means to fix dental problems, but what we really like to see is a well-cared for, beautiful smile.

Along those lines, parents worry about when their child’s baby teeth should come in and what should be done with them. So, here’s some background on these teeth that will one day be the domain of the Tooth Fairy!

Primary dentition

Primary dentition. Doesn’t that sound like something that may have been taught way back in a one-room schoolhouse in Nashua? It actually is simply the term for the arrival of a child’s 20 baby teeth. Baby teeth are clinically known as deciduous teeth. They will include four incisors, two canines, and four molars on each jaw. These begin erupting through the gums around the age of six months. One or two teeth will break through each month.


The first teeth to come in are the bottom central incisors, followed by the four front teeth on the upper jaw. The rest of the teeth descend in pairs, usually one on each side. Your child should have around 10 teeth on top and bottom somewhere between 2 and 3 years old. These teeth will last until around 6 or 7 when they will start to shed. This is the time to alert the Tooth Fairy and get those silver dollars collected! Those deciduous teeth will be mostly gone by the age of 13, replaced by permanent teeth.

Some things you didn’t know about baby teeth

While we are near some really esteemed centers of higher learning here in Nashua, we bet even university professors in the various schools of dentistry could be stumped by these facts about baby teeth. Impress your friends at garden parties when this long winter finally gives it up.

  • Girls get their teeth earlier than boys.
  • Teeth in the lower jaw erupt before those in the upper jaw.
  • Children who are shorter in height may have delayed tooth eruption.
  • If you live in a warmer climate, your kid’s teeth will come in earlier.
  • People living in urban areas get teeth faster than rural kids.
  • Birth rank can make older kids get their teeth earlier than their youngest brother or sister.

A couple tips for baby tooth hygiene

  1. Before your child’s teeth erupt, clean your baby’s gums and the erupting teeth by rubbing a clean, damp washcloth along the baby’s upper and lower gums.
  2. When the teeth come in, start brushing your baby’s teeth at least two to three times a day with a soft-bristled toothbrush and water.
