You might not think twice about brushing and flossing — until you realize you’ve got something stuck between your teeth and your breath isn’t exactly minty fresh.

But if you’re someone who skips oral care now and then, it might be time to rethink that habit.

Because oral hygiene isn’t just about a clean smile or fresh breath — it’s about your overall health, and believe it or not, it may even impact how long you live.

Your oral health — the state of your teeth, gums, and supporting tissues — allows you to eat, speak, smile, and breathe comfortably.

When it’s compromised, even simple things like eating or talking can become painful or embarrassing.

But your mouth is more than just a chewing tool or a cosmetic feature — it’s a window into your body’s overall health and one of the strongest predictors of healthy aging.

Your mouth is home to a thriving ecosystem of microorganisms known as the oral microbiome — a community of bacteria, fungi, viruses, and other microbes.

Most of the time, these microbes live in harmony, forming a thin biofilm on your teeth, gums, tongue, and cheeks.

A healthy oral microbiome helps to:

But this balance — called homeostasis — is fragile. It can be disrupted by factors like:

When that balance breaks down, it leads to oral dysbiosis, where harmful bacteria take over. This thickens the biofilm, forming plaque — that sticky film you feel on your teeth.

Plaque traps acid and bacteria against your teeth and gums, weakening enamel and irritating tissue. Left unchecked, it can lead to:

And here’s where things get serious: gum disease isn’t just a mouth issue — it’s linked to diabetes, heart disease, and even cancer.

When harmful bacteria build up, your immune system jumps into action. It releases chemical signals to fight infection, creating inflammation.

That’s fine for short-term healing — but when infection lingers, your immune system stays “on,” leading to chronic inflammation.

And that inflammation doesn’t stay in your mouth. It can spread throughout your body, fueling a host of health problems.

It's crucial to reiterate that no single gene causes UC. It is a polygenic disease, meaning it results from the accumulation of many small risk variants, combined with external factors.

Inflammation in your gums can enter the bloodstream, driving systemic inflammation, a known contributor to chronic diseases.

In some cases, oral bacteria themselves travel through the blood — either through inflamed gum tissue or via the digestive system — and end up in distant organs.

Once there, they can contribute to conditions such as:

In fact, a recent study found that people with specific oral microbes had a threefold higher risk of developing pancreatic cancer.

And that’s not all — having fewer than 10 natural teeth is linked to a higher risk of death from all causes.

Here’s the takeaway: brushing and flossing aren’t just cosmetic. They’re life-extending habits.

Maintaining good oral hygiene can:

So, the next time you reach for your toothbrush, remember: you’re not just caring for your smile — you’re investing in your long-term health.

Because sometimes, the simplest habits — like brushing twice a day — are the most powerful.
