The Oral Health Series: Part 3 - Understanding Gum Health

I'll be honest - I've found this article surprisingly difficult to write.

Not because I don't know what to say, but probably because I have far too much I want to say!

Gum health is something I'm incredibly passionate about and something I talk about every day. Those of you who see me regularly will already know this — and are probably wondering how I'm going to get through an entire newsletter without mentioning plaque...

Spoiler alert: I'm not!

But underneath all my talk about plaque, bleeding gums and cleaning between your teeth, there is a reason I keep coming back to gum health. Our gums and the tissues underneath them provide the foundations that support our teeth, and changes can sometimes happen without us really noticing.

Some people already know something isn't quite right. They may notice bleeding when brushing, tenderness, redness or changes around their gums.

For others, finding out there is inflammation or gum disease can come as a complete surprise. Everything feels fine and they haven't noticed anything that would make them think there's a problem.

So rather than trying to tell you absolutely everything I know about gums - we'd be here for a while! - I'm going to keep this one to the things I think are most useful for you to understand about your own gum health.

And perhaps the best place to start is with one of the questions I hear most often...

Why do my gums bleed?

The short answer is that bleeding is usually a sign of inflammation.

And this is where - you guessed it - we need to talk about plaque.

Plaque is a soft, sticky biofilm that naturally forms on our teeth. It contains lots of different bacteria and starts building up again after we clean our teeth.

First things first: we all have plaque.

It doesn't mean you have a dirty mouth, and the aim isn't to somehow achieve a completely plaque-free mouth - we'd be fighting a losing battle!

Problems can begin when plaque is left sitting around the gum margin for longer periods. The bacteria within it interact with our body and can trigger an inflammatory response. One of the signs of that inflammation can be bleeding.

But here's where it becomes a little more interesting: we don't all respond in exactly the same way.

Our mouths naturally contain a whole community of microorganisms - our oral microbiome - and our individual response to plaque can be influenced by lots of different things. That's why two people who appear to have similar cleaning habits won't necessarily have exactly the same gum health.

Regularly mechanically disrupting the biofilm - in other words, physically breaking it up with brushing and cleaning between the teeth - helps to support a healthier balance in the mouth.

When I assess your mouth, looking at where plaque is sitting alongside how your gums are responding helps me build a much clearer picture of your gum health.

And that brings us to what might actually be happening underneath them...

What do we mean by gum health?

When we talk about gum health, we're talking about the health of all the tissues that surround and support your teeth - not just the gums you can see, but the bone and other supporting tissues underneath too.

When I assess your gum health, I'm looking for inflammation and bleeding, checking how the gums sit around each tooth and assessing the health of the supporting tissues underneath.

And yes... this is where my little “pokey thingy” comes in (very technical term!).

I know what some of you are thinking...

“Well, my gums don't bleed at home.”

It's a fair thought.

But healthy gums shouldn't routinely bleed when they're gently assessed. If they do, it gives me useful information about where inflammation may be present - including changes you may not have noticed yourself.

One of the ways I often explain what's happening is to think about how the gum sits around the tooth.

Healthy gums - a healthy cuff

Healthy gum sits snugly around the tooth, a little like the cuff of a shirt. It's generally firm and comfortable, with little or no bleeding when you brush or when I gently assess it.

There are no signs of active inflammation and the bone and supporting tissues underneath remain healthy. This is where we want to be - and where prevention and regular monitoring help us to stay.

Gingivitis - when the cuff becomes inflamed

Gingivitis means inflammation of the gums.

As the gum becomes inflamed, that snug cuff can become swollen and more like a loose sleeve around the tooth. You may notice redness, swelling or bleeding when brushing and cleaning between your teeth - or you might not notice anything at all.

The important thing to know is that gingivitis is reversible. At this stage, the bone and supporting tissues haven't been destroyed. With effective daily cleaning, professional support where needed and a little time, the inflammation can settle and the gums can return to health.

Periodontal disease (gum disease) when a pocket develops

For some people, inflammation can progress further and the space between the gum and tooth becomes deeper, creating what we call a periodontal pocket.

Think of that sleeve around the tooth becoming deeper. Plaque can then sit further below the gum margin, where it's much harder for you to reach at home. If it remains undisturbed, the biofilm can become more mature and established, with changes in the bacteria living within it.

This is where professional treatment may be needed to disrupt and remove those deposits.

At this stage, the inflammation is no longer affecting just the gum. The bone and other tissues supporting the tooth can begin to be damaged and lost.

What might you notice?

Sometimes very little - particularly in the earlier stages.

You might notice receding gums, teeth looking longer, spaces becoming more obvious, food trapping, or teeth beginning to move or change position. If enough support is lost, teeth can become mobile and, in some cases, may eventually be lost.

That can sound frightening, but it isn't the outcome for everyone. How periodontal disease affects each person varies, which is another reason finding it early and monitoring how it responds to treatment is so important.

Unlike gingivitis, lost support doesn't simply grow back. But periodontal disease can be stabilised and managed.

Our aim is to control the inflammation, protect the support that remains and reduce the risk of further progression. Treatment combines professional care with support for your home-care routine, while also taking into account other factors that may influence your gum health.

It can take time. We need to treat, allow healing and then reassess how your gums have responded. After that, ongoing supportive care and monitoring help us keep things as stable as possible.

Ultimately, we're trying to control the disease, protect the support that's still there and, where possible, help you maintain your teeth for as long as possible.

So, what can you do?

After all of that, you'll probably be relieved to know I'm not going to give you a huge list of things you should be doing!

Gum health is a team effort. What you do at home matters, but so does understanding what works for you. Sometimes that means changing an interdental brush size, tweaking how you use your toothbrush or simply giving a tricky area a little more attention.

Sometimes I'll suggest a change. Sometimes I'll tell you to keep doing exactly what you're doing. And sometimes life gets in the way and things slip a little - that's normal too. We simply work from where you are.

I'm not looking for perfection, and I'm certainly not secretly marking your homework! I'm looking at how your mouth is responding.

That's why I ask questions, measure plaque and bleeding, and keep checking those gums over time. It helps us spot changes early and decide together what, if anything, needs to change.

And those same conversations also help me think about your risk of tooth decay - but I'll save that one for the next newsletter!

And there's another part of the picture too. Your general health, medications and lifestyle can influence what we see - because, as I'll come back to in another article, the mouth really can be a window to the rest of the body.

So yes... I'll probably keep talking about plaque! But hopefully now you'll know why - it's all part of helping you keep your mouth healthy for the long term.
