Bleeding gums are common, but they are never normal. Healthy gums don’t bleed when you brush, the same way healthy skin doesn’t bleed when you wash. In most people the cause is plaque sitting along the gumline, and two weeks of better cleaning fixes it. In some people it’s the first sign of something that needs treating properly.

Here’s how to tell which one you’re dealing with.

Plaque is a soft film of bacteria that builds up where your teeth meet your gums. Leave it there and your gums react — they swell, turn a deeper red, and bleed at the slightest touch. That’s gingivitis, and it’s reversible.

If plaque stays long enough, it hardens into tartar. You can’t brush tartar off. It sits under the gumline holding bacteria against the bone that supports your teeth, and the body starts breaking that bone down. That’s periodontitis, and it isn’t reversible — you can stop it, but you can’t get the lost bone back.

The gap between those two stages is where most people lose teeth they didn’t need to lose.

• Brushing harder. Almost everyone’s instinct when gums bleed is to avoid the area or scrub it. Both make it worse. Plaque needs removing gently, every day.
• Skipping between the teeth. A brush cleans three of the five surfaces of a tooth. Floss or interdental brushes do the other two, and those two are where gum problems usually start.
• Smoking. Smokers often bleed less, because nicotine tightens the blood vessels. The disease is still progressing underneath, just quietly.
• Diabetes, especially when blood sugar isn’t well controlled. It works both ways: gum disease makes blood sugar harder to control too.
• Pregnancy. Hormonal changes make gums more reactive to the same amount of plaque.
• Some medications — blood thinners, certain blood-pressure drugs, some epilepsy medication.

Give it two weeks of doing this properly before you conclude anything:

1. Brush twice a day for two full minutes, at a slight angle into the gumline, with soft bristles. Set a timer. Almost nobody brushes as long as they think they do.
2. Clean between your teeth once a day. Floss if you’re good at it, interdental brushes if you’re not — for most adults the little brushes are easier and work better.
3. Don’t stop because it bleeds. Inflamed gums bleed for the first few days of proper cleaning. That settles as the inflammation does.
4. Use a fluoride toothpaste and don’t rinse your mouth out afterwards. Spit, don’t rinse.

If the bleeding has stopped after two weeks, it was gingivitis and you’ve dealt with it. Keep going.

Book an appointment if any of this is true:

Loose teeth in an adult are not something to monitor at home. By the time a tooth moves, a fair amount of supporting bone has already gone.

The first visit is mostly looking and measuring. We check the depth of the space between each tooth and the gum with a small probe — healthy is 1–3mm, and anything over 4mm means bacteria are living somewhere your toothbrush will never reach. We’ll usually take X-rays to see the bone level.

For gingivitis, a professional clean removes the tartar and you take it from there.

For periodontitis, the treatment is scaling and root planing — cleaning the root surfaces below the gumline, usually over a couple of visits with the area numbed. We use lasers alongside it to decontaminate the pockets and settle the tissue down, which in our experience makes the days afterwards a lot more comfortable.

After that it’s maintenance. Most patients with a history of gum disease come in every three to four months rather than every six, because the pockets recolonise faster.

More on our gum treatment and periodontal care.

Gum disease is painless until it’s advanced. There’s no toothache, no sensitivity, nothing that makes you pick up the phone. Patients regularly tell us they had no idea anything was wrong, and they’re not being careless — it genuinely doesn’t hurt.

That’s why the bleeding matters. It’s often the only warning you get, and it’s easy to dismiss as “I brushed too hard”.

Is it normal for gums to bleed when brushing? No. It’s common, but it isn’t normal. Bleeding means inflammation, and inflammation means bacteria are sitting somewhere they shouldn’t be.

Will bleeding gums heal on their own? Gingivitis will, with two weeks of proper brushing and cleaning between the teeth. Periodontitis won’t — it needs a dentist to remove tartar from below the gumline.

Should I stop brushing the area that bleeds? No — that’s the opposite of what helps. Clean it gently and thoroughly. The bleeding settles within a few days once the inflammation does.

Does mouthwash fix bleeding gums? It helps, but it won’t do the job alone. Mouthwash can’t remove plaque that’s already stuck to the tooth, and it can’t touch tartar at all.

Can bleeding gums cause bad breath? Often, yes. The bacteria in deep gum pockets produce sulphur compounds, which is a smell mints don’t cover for long.

Is gum disease linked to other health problems? There’s good evidence linking gum disease with diabetes control, and associations with heart disease and adverse pregnancy outcomes. If you’re diabetic, treating your gums is worth doing for more than your teeth.

Can I have a cleaning while pregnant? Yes, and it’s a good idea. Pregnancy gingivitis is very common. The second trimester is usually the most comfortable time for a longer appointment.

Does scaling loosen or damage teeth? No. It removes the tartar that was holding bacteria against the bone. Teeth can feel different afterwards because the tartar was acting like a splint — that’s the disease showing itself, not the cleaning causing it.

Will my gums grow back after treatment? Gum tissue can tighten and become healthy again. Lost bone doesn’t grow back on its own, which is why catching it early matters so much.

If your gums have been bleeding for more than a couple of weeks, get them looked at. It’s a short appointment and the answer is usually reassuring.
