Adult Oral Health Survey 2023: 3. Clinical oral health: Periodontal Disease and Erosive Tooth Wear among adults in England
The 2023 Adult Oral Health Survey reveals that periodontal disease and erosive tooth wear are highly prevalent among dentate adults in England, with both conditions increasing in severity with age and exhibiting significant inequalities, particularly for advanced cases.

The Big Picture: A Check-Up for England's Mouths
Imagine the researchers took a giant, representative snapshot of the mouths of over 1,500 adults in England (aged 16 and up). They didn't just ask people how they felt; they went into people's homes and acted like detectives, looking closely at teeth and gums.
This paper focuses on two specific "villains" that attack our mouths: Periodontal Disease (gum disease) and Erosive Tooth Wear (teeth wearing down like sandpaper).
The main takeaway? As we keep our natural teeth longer (which is a good thing!), we are also keeping the problems that come with them. The older we get, and the poorer our circumstances, the more likely we are to have these issues.
Villain #1: Periodontal Disease (The "Gum Leak")
Think of your gums as a tight, healthy seal around a fence post (your tooth). Periodontal disease is like that seal starting to rot and pull away, creating deep, hidden pockets where dirt and bacteria can hide.
What the survey found:
- It's very common: About 40% of adults have at least one "leak" (pocket) in their gums that is 3.5mm or deeper. That's like finding a crack in the foundation of a house.
- It gets worse with age:
- Young adults (16–24) are mostly safe (only 15% have leaks).
- By the time people are 65–74, more than half have these deep pockets.
- The "Deep" Pockets: About 12% of adults have very deep leaks (over 5.5mm). This is the "structural damage" stage. In the 65–74 age group, this jumps to nearly 23%.
- The "Poverty Gap": This is a major finding. The gap between the richest and poorest groups is huge.
- In the poorest group, nearly 1 in 4 people have those very deep, dangerous pockets.
- In the richest group, it's less than 1 in 10.
- The paper notes that even though poorer groups often have fewer teeth (because they might have been lost earlier), the teeth they do have are in much worse condition than those of wealthier people.
Other signs of trouble:
- Receding Gums: About 20% of adults have gums that have pulled back, exposing the roots (like a tree trunk showing above the soil). This affects over a third of people over 55.
- Loose Teeth: About 9% of adults have teeth that wiggle. This jumps to nearly 18% for those over 75.
Villain #2: Erosive Tooth Wear (The "Sandpaper Effect")
Imagine your teeth are made of hard ceramic. Erosive wear happens when acids (from food, drink, or stomach acid) act like sandpaper, slowly grinding away the surface. This isn't caused by cavities; it's caused by "dissolving."
What the survey found:
- Almost everyone has some wear: A massive 71% of adults have some sign of their teeth being worn down.
- It's a "Time Bomb":
- Mild wear: Most people have minor scratches.
- Moderate wear: About 22% of adults have distinct defects where up to half the tooth surface is gone.
- Severe wear: About 4.5% have lost more than half the surface of a tooth. This is rare in young people but affects about 10% of those over 65.
- The "Front Teeth" Factor: The front teeth are hit the hardest. Even when looking only at the front teeth, 66% of adults show signs of wear.
- The "Poverty Gap" again: Just like gum disease, wear is worse in poorer groups.
- 76% of the poorest group have wear, compared to 67% of the richest.
- The most severe wear (losing half the tooth) is double as common in the poorest group compared to the richest.
The "Why" and the "How"
The researchers compared this 2023 data to surveys from the past (1988, 1998, 2009).
- Are things getting worse? Surprisingly, the overall risk of gum disease seems to have gone down slightly since 1988, even though people are keeping their teeth longer. The authors suggest this might be because more people are using floss and electric toothbrushes now than before.
- The "Missing Teeth" Problem: The paper admits a tricky limitation. If someone had terrible gum disease and lost their teeth years ago, they aren't in this survey anymore. So, the numbers might actually be underestimating how bad the problem really is for the whole population. It's like judging the health of a forest only by looking at the trees that are still standing, ignoring the ones that fell down long ago.
The Bottom Line
The paper paints a picture of an aging population that is keeping its natural teeth, which is great for quality of life. However, keeping those teeth comes with a cost:
- Gum disease and tooth wear are everywhere, especially as we get older.
- Inequality is stark. Being poor significantly increases your risk of having severe gum disease and worn-down teeth.
- It's a chronic issue. Once the damage is done (gum pockets or worn enamel), it doesn't go away. It requires long-term management.
The authors conclude that because these problems are so common and unevenly distributed, dental teams and public health planners need to focus heavily on early detection and helping the most vulnerable groups before the damage becomes irreversible.
