If your gums bleed when you brush or floss, it’s easy to shrug it off. Many people think it’s normal. It isn’t.
Healthy gums do not bleed — ever.
Bleeding is your body’s way of signalling that something isn’t right. At Hello Dental in Colchester, we often see patients who have lived with bleeding gums for months (sometimes years) before realising it’s a warning sign of gum disease.
Let’s talk about why it happens, what it means, and what you can do about it.
The most common cause of bleeding gums is plaque build-up.
Plaque is a sticky film of bacteria that forms on your teeth every day. If it isn’t removed effectively through brushing and flossing, it irritates the gum tissue. This irritation leads to inflammation — known as gingivitis.
When gums become inflamed, they may:
Bleed when brushing or flossing
Look red rather than pale pink
Appear swollen or puffy
Feel tender
The important thing to know? Gingivitis is reversible.
With professional cleaning and improved oral hygiene, your gums can return to health.
If gingivitis is left untreated, it can progress to periodontitis.
This is a more advanced form of gum disease where the inflammation spreads deeper, affecting the bone that supports your teeth. Over time, this can lead to:
Gum recession
Loose teeth
Persistent bad breath
Tooth loss
Unlike early-stage gum disease, periodontitis cannot be completely reversed — but it can be managed.
That’s why early intervention is so important.

This is a common misconception.
While brushing aggressively can irritate your gums, healthy gum tissue is resilient. If your gums bleed regularly, the underlying cause is usually inflammation — not brushing technique alone.
In fact, when gums bleed, many people stop brushing the area. Unfortunately, this allows more plaque to accumulate, making the problem worse.
The solution isn’t to avoid brushing. It’s to brush effectively and gently — and to address the inflammation.
Although plaque is the main culprit, other factors can contribute, including:
Smoking
Hormonal changes (such as pregnancy)
Certain medications
Diabetes
Stress
Poorly fitting dental appliances
At Hello Dental, we take time to understand the full picture of your oral and general health before recommending treatment.
Healthy gums are firm, pale pink, and don’t bleed. Here’s how to keep them that way:
Use a soft-bristled toothbrush and fluoride toothpaste. Angle the brush towards the gumline and use small circular motions.
Floss or use interdental brushes daily. This is essential — your toothbrush cannot reach these areas.
Professional cleans remove hardened plaque (tartar) that you cannot remove at home.
If you notice bleeding, book an appointment sooner rather than later. Early treatment is simpler, quicker, and more comfortable.

Gum disease doesn’t just affect your mouth.
Research has shown links between gum disease and wider health conditions, including heart disease, diabetes, and adverse pregnancy outcomes. Inflammation in the mouth can contribute to inflammation elsewhere in the body.
Looking after your gums is part of looking after your overall health.
If your gums bleed, even occasionally, it’s worth getting them checked.
At Hello Dental in Colchester, we focus on prevention and early intervention. Our friendly team will assess your gum health, provide tailored advice, and — if needed — carry out a thorough professional clean to get things back on track.
Healthy gums don’t bleed. If yours do, let’s fix it.
