The creatures that live in your mouth


Your body is basically an Airbnb

It sounds a little gross but our bodies are host to, well, a whole host of micro-organisms. We all know about bacteria, but other single-celled organisms, and even fungi and viruses, can also be found inside our bodies. One body part that’s chock-full of microbes is the mouth — it’s second only to the number of microbes in our gut! The ecosystem of all these organisms is known as a microbiome.

The things that live in your mouth

It’s actually a whole community in there. Over 700 types of microbes can be found in the human mouth, and they all contribute to important bodily functions like digestion, developing the immune system, and detoxifying chemical substances.

They live in different habitats within the mouth — the microbes found on our teeth will be different from those found on the tongue, and so on. But they all support each other as part of the larger microbiome that they belong to.

The good and the bad

The makeup of each of our microbiomes is so unique to us that some argue they could even function as a microbial “fingerprint”. But they’re so delicately balanced that small changes in the microbiome could spell disaster for the rest of the body.

An out-of-balance microbiome goes into a state called dysbiosis. In the mouth, this often leads to gum disease or caries. More significantly though, is that dysbiosis in the mouth can also lead to dysbiosis in the gut. So it’s important to look after all our friends living in our mouths by keeping good dental hygiene habits and avoiding smoking and high-sugar foods.

Remember fidget spinners?

Touted as a fix-it for kids with ADHD and anxiety, these spinning toys were all the rage in 2017. You might recall that they were so hugely popular among children that schools started confiscating and banning them because they were thought to be doing more harm than good. It was also highly debated whether they even did any good at all.

When you can’t sit still

Fidget spinners aside, it’s generally agreed upon that fidgeting occurs when our minds are either under-or over-stimulated. When things get too easy, we fidget to maintain attention on a particular topic, and when things get too hard, we fidget to relieve stress and anxiety.

Another theory about why we fidget is that it’s an automatic way for our bodies to burn calories.

Helping fidgeters fit in

If you find that you tend to fidget a lot, there’s nothing wrong with that — if people are bothered by it, you need only adapt your fidgeting or your environment to ensure that everyone is comfortable.

And of course, fidget spinners aren’t the only options out there — fidget cubes were popular around the same time, and there are always good old-fashioned stress balls to consider, as well as more uncommon tools like mini zen gardens. So forget about fads and take the time to find out what works for you, specifically.

Masks up… forever?

In the early days of the Covid-19 pandemic, many of us struggled with the concept of wearing masks 24/7 — some of us more than others. But what’s going to happen after the pandemic finally ends?

By now, mask-wearing has become an integral part of our daily lives. From fashion trends to social behaviours, they’ve changed society in several ways.

They’ve also (unfortunately) had an impact on our environment — experts estimate that 129 billion face masks are used and disposed of every month. If you laid those all out side by side, that’s about 3 times the size of the whole of Singapore. To combat this issue, some countries have been developing biodegradable masks or masks made out of waste products.

In most Asian countries, it’s always been fairly common for people who aren’t feeling well to don a face mask when they go out in public (especially since the outbreak of SARS in 2003). So when the time came for us all to wear masks, there wasn’t as much resistance as there was (and is) in countries like the USA.

Moving forward out of the pandemic in the US, some believe that American culture might be fundamentally changed into a mask-wearing one — whether that be for personal benefit or out of consideration for other people. 

So while we won’t all be constantly wearing masks forever, it seems pretty likely that they’re here to stay worldwide, if only when people start to fall ill.
