Bacteria are microscopic, single-celled organisms that are considered crucial for life and are found almost everywhere on Earth, and your mouth is no exception! While some are beneficial and contribute to healthy processes, like digestion, others can be harmful to your dental condition.
You’re not alone if that leads you to wonder how many bacteria are actually in your mouth, what they do, and when you should be worried about your oral health. If you’re curious, continue reading to learn more about it!
How Many Bacteria Live in Human Mouths?
Would you be surprised to learn that human mouths contain an estimated 6 to 20 billion microbes, comprised of about 700 unique species? These can colonize on various surfaces, such as your tongue, the roof of your mouth, your teeth, and along your gumline.
That might sound unappealing, but it’s perfectly normal and necessary to develop an oral microbiome that contains bacteria, fungi, viruses, and other microbes to support your oral and overall well-being. However, there are also unhealthy germs in your mouth which can become problematic if they overwhelm the good bacteria.
What Do The Bacteria in My Mouth Do?
The different microscopic organisms in your mouth work together to form a sticky material, called a matrix. Some of these communities assist with digesting food and even help protect you from harmful germs by keeping their growth in check.
But if certain bacteria, such as Streptococcus mutans or Streptococcus sobrinus, are able to thrive, you might develop cavities or other oral issues. These species thrive on sugar and produce acids that erode your enamel, leading to caries that might cause additional concerns, such as periodontal problems or damage like chips and cracks.
How Can I Avoid Dental Problems Caused by Bacteria?
Fortunately, there are several ways you can help prevent harmful germs from causing dental problems. For instance, brushing and flossing your teeth twice daily clears plaque and bacteria to keep them from forming plaque or tartar on your enamel or connective tissues. You can also minimize your consumption of sugary or starchy foods, which they need to survive.
Finally, you can also help preserve a beautiful, healthy smile by visiting your dentist every six months for a routine checkup and cleaning. This allows them to monitor your dental condition and catch and treat any areas of concern, including tooth decay, before they progress.
If you’re unsure whether you have developed an oral issue, you can learn more by consulting your provider!
