Hello,

This is TU Dental Clinic, here to bring you a smile. ^^

Today, we’d like to talk about how the number of teeth is related to health and mortality.

As we get older, it’s not just our physical strength that declines. There are things that quietly, and slowly, disappear.

Those are our teeth.

Many people think of teeth only as a matter of inconvenience. But teeth are more than just tools for chewing. They are the foundation that supports the health of the entire body.

And recent studies show that this fact is also connected to survival.

In a study of seniors aged 75 and older, the fewer teeth they had, the significantly higher their risk of death was.

According to the analysis, the more healthy teeth a person had, the clearly lower the mortality rate became, and this trend was especially confirmed step by step in men.

When there were no healthy teeth at all, the mortality rate was 17.3%

△ 1–5: 12.1% △ 6–10: 9.5% △ 11–15: 8.4% △ 16–20: 7.2% △ 21 or more: 6.9%

👉 As the number of teeth increased, the mortality rate gradually decreased

Women showed the same pattern. When there were no healthy teeth, the mortality rate was highest at 8.4%,

and as the number of teeth increased, △ 5.2% → 4.4% → 3.9% → 3.9% → 3.4% showed a steady decline.

The key point of this study is simple. Teeth are not just an oral health issue; they are an indicator that reflects overall health.

Why do teeth affect life itself?

✔ When chewing ability declines, nutritional intake breaks down ✔ Chronic inflammation spreads throughout the body ✔ The immune system gradually weakens

In the end, tooth loss is not just a simple inconvenience.

It leads to a problem that undermines the foundation of overall health.

Then how should teeth be protected?

The key to dental health is ‘preserving your natural teeth.’ The goal is to keep as many as possible for as long as possible. If the number of teeth is connected to survival, the 기준 we should choose is clear.
