The Facts Behind Oral Bacteria

Bacteria, it’s good, it’s bad, it’s everywhere!

But what exactly is the purpose of bacteria do? Especially in your mouth? Not all bacteria are bad; some are actually necessary to maintain a proper hygienic balance.

Learn more about oral bacteria from Dr. Mark Reichman.

Fact 1

“Oral bacteria” indicates the billions of microorganisms that populates the oral cavity. Streptococci and staphylococci are the some of the most widely known.

Fact 2

Our saliva flushes harmful bacteria through the mouth. This makes it more difficult for bacteria to stick to the surfaces of our teeth.

Fact 3

The mouths of infants are free from bacteria when they are first born. Bacteria is first introduced into their mouths by their mothers within hours of birth; it’s a natural process of kissing and food sharing.

Fact 4

There are between 500 and 1,000 different kinds of bacteria in our mouths.

Fact 5

Hormonal changes during pregnancy put imminent mothers at higher risk of tooth erosion. Morning sickness and general hormonal changes increase acidity, which wears away enamel.

Fact 6

The tongue holds a large quantity of bacteria. This is why it is important to clean the tongue, because a buildup of bacteria on the tongue can lead to to gum disease and bad breath.

Fact 7

Some foods can wash away bacteria from the teeth. Try crunchy vegetables like celery and carrots to stimulate the gums. Acidic fruits like apples wash the teeth clean by increasing saliva production.

Fact 8

Oral bacteria multiply every 4-5 hours. That’s why it’s so critical to hygiene to brush your teeth twice a day!

Fact 9

Smoking increases the risk of tooth decay and periodontal disease. Tobacco destroys good oral bacteria and supplements the growth of harmful oral bacteria.
