How Many Bacteria Live in Your Child’s Mouth?

Have you ever given thought to how many bacteria are around you and your family at all times? Since they are so small, it is easy to forget that they are there. On the other hand, this is something many of us try not to think about. The truth is that bacteria are everywhere, even in our mouths. We may not be able to feel or taste them, but there are entire colonies existing beneath our tongues. Read on to learn more about oral bacteria, and how they benefit us!

How Many Bacteria Are in the Mouth?

It is difficult to come up with an exact number, but there have been over 700 strains of bacteria detected in the human mouth. However, most people only have approximately 34 to 72 varieties. It is estimated that the mouth contains about 20 billion oral microbes. Some species of bacteria can double their numbers every 20 minutes. Most bacteria don’t pose threats. Some are even beneficial – like probiotics. These are the bacteria that help you digest your food. There are even certain types of bacteria that are there to protect the teeth and gums from harm.

Which Kinds of Bacteria Are Harmful?

There are two types of bacteria in the mouth that are particularly harmful. The most common one is called Streptococcus mutans. This is the bacteria that feeds off the sugars and starches that your child eats. The problem is that these bacteria produce acid as a byproduct on their digestion. This weakens your child’s enamel and can result in tooth decay.

The other harmful bacteria that can be found in the mouth are called Porphyromonas gingivalis. In individuals with excellent oral health, these bacteria are likely not present. These bacteria are usually a sign of periodontitis, or late-stage gum disease.

How to Manage Oral Bacteria

It is normal for your child to have bacteria in their mouth, but having large quantities of harmful bacteria can result in problems. By helping them brush twice and floss every day, some of these bacteria are cleaned away. Other important steps include routine cleanings and checkups, using mouthwash (if age appropriate), and limiting sugary and starchy foods.

Bacteria plays an important role in your child’s oral health, so having a healthy balance is key. With proper maintenance, your child can keep up a happy, healthy smile!
