Of all the things patients tell me, one comes up more than any other: "my gums bleed sometimes, but that is normal, isn’t it?" It is understandable that people think so, because it happens to so many. The answer, though, is no. Healthy gums do not bleed, any more than healthy skin bleeds when you rub it.
Bleeding is a sign of inflammation. And inflammation means something is present that your body is reacting to — almost always bacterial plaque that has sat in one place for too long.
Why gums bleed
Plaque is a thin, sticky layer of bacteria that forms continuously on your teeth. If it is left along the gum line, your immune system responds: more blood flows to the area, the tissue swells and becomes fragile. Gums in that state are redder, slightly puffy, and bleed at the lightest touch. This stage is called gingivitis.
The good news about gingivitis is that no lasting damage has been done. If the plaque is removed consistently, the gums usually heal completely within a week or two.
The instinct that makes it worse
This is where it goes wrong for many people. Seeing a spot bleed, they brush it more gently or avoid it altogether. That is a logical response — something appears to hurt, so you stop doing it.
But it is exactly backwards. Sparing that spot leaves more plaque behind, the inflammation intensifies, and it bleeds still more. A cycle sets in that sustains itself.
When it is more than gingivitis
If inflammation continues for years, it can spread to the bone holding your teeth in place. That is periodontitis, and unlike gingivitis the damage is not reversible. Bone that has been lost does not come back. We can, however, halt the process and preserve what remains.
Signs that may point to periodontitis:
- Gums receding, making teeth look longer
- Persistent bad breath or an unpleasant taste
- Teeth becoming loose or shifting position
- Gaps opening between teeth where there were none before
- Pus along the gum line
If any of that sounds familiar, do not wait. Periodontitis is generally painless, which is precisely why people come late. The sooner we measure how deep the inflammation goes, the more there is to save.
What you can do yourself
Brush twice a day for two minutes with a soft brush, and clean between your teeth once a day — that last part is where most people gain the most, because a brush simply does not reach there. If you smoke, stopping is the single biggest improvement you can make for your gums; smoking also masks bleeding, which lets problems go unnoticed for longer.
If you are unsure whether what you are seeing is normal, have it checked. That is a single appointment, and in the great majority of cases the conclusion is reassuring.
