Bleeding gums are not something to live with

Blood in the sink is the first stage of gum disease, not a sign of brushing too hard. Caught early it reverses completely. Left alone it does not.

Blood in the sink is a signal, not a habit

Healthy gums do not bleed when you brush them. They do not bleed when you floss, and they do not bleed when you bite into an apple. If yours do, the bleeding is telling you something, and the most common explanation people give themselves is the wrong one.

Most people assume they are brushing too hard. Occasionally that is true, usually with a stiff brush and a scrubbing action. Far more often the opposite is the case. The gum around a tooth is inflamed because bacteria are sitting along the gum line, the blood vessels in it are swollen and fragile, and the brush is simply the thing that touches it. People then start avoiding that spot, the plaque builds up further, and the bleeding gets worse. It is one of the few problems in dentistry that gets better if you brush the sore area more carefully rather than less.

What is actually happening in your mouth

Plaque becomes tartar

Plaque is a soft film of bacteria that forms on teeth within hours of cleaning them. Brushing removes it. What brushing does not remove is what happens when plaque is left alone for a few days: minerals from your saliva harden it into tartar, also called calculus. Tartar is rock hard, bonded to the tooth, and no toothbrush, mouthwash or whitening paste will shift it. Its rough surface collects more plaque, so the problem builds on itself.

Tartar causes gingivitis

Gingivitis is inflammation of the gum, and it is the stage almost everyone with bleeding gums is at. The gums look redder than they should, they may be puffy, they bleed when disturbed, and breath is often stale. There is usually no pain at all, which is exactly why it gets ignored for years.

The important thing about gingivitis is that it is completely reversible. Remove the tartar, keep the plaque off afterwards, and the gum settles back down within a week or two. Nothing is lost permanently, and no treatment beyond a clean and better daily habits is needed.

The point where it stops being reversible

If tartar is left along and under the gum line for long enough, the inflammation stops being confined to the gum and starts affecting the bone that holds the tooth in its socket. That is periodontitis, and it is a different situation entirely.

The gum detaches slightly from the tooth and forms a pocket. Tartar spreads down into that pocket where no brush can reach. Bone is lost around the root. Bone does not grow back. Everything before that line can be undone; the bone cannot. Over years the pockets deepen, the teeth loosen, gums recede, and eventually otherwise healthy teeth with no decay in them at all become loose enough to need extraction.

This is the quiet way most adults lose teeth. Not decay. Not accidents. Gum disease that bled politely into the sink for ten years and was never mentioned to anyone. Signs that it has moved past gingivitis include gums that have shrunk back so teeth look longer, teeth that feel slightly mobile, persistent bad breath, gaps opening between front teeth that were never there before, and a bad taste from one particular spot.

What scaling and polishing actually does

Scaling and polishing is what removes it. It is not a cosmetic treatment, whatever the name suggests. Scaling is the removal of hardened tartar from the tooth surfaces and from just under the gum line, using an ultrasonic tip and hand instruments. Polishing afterwards smooths the surface so plaque takes longer to settle again, and it lifts surface staining.

In Sharjah much of that staining is karak and black tea, along with coffee and tobacco. The part that matters is the tartar underneath, which is what the gums are reacting to.

It takes around half an hour. Gums that are already inflamed can be tender during the clean and may bleed while the tartar comes off, which is the inflammation, not damage being done. They usually feel better within a couple of days and stop bleeding within a week or two once you are brushing a clean surface.

Deal with it now, or lose teeth later

Scaling and polishing is one appointment. Set that against what the alternative costs, not just in money. A tooth lost to gum disease is not replaced by a filling. It is replaced by nothing, or by a bridge, a crown on a neighbouring tooth, or dentures later on. Al Najma does not place implants, so if that is the road you end up on we will say so plainly and point you to a clinic that does.

The cheaper path is uninteresting by comparison. A check-up tells you which stage you are at. A clean deals with it if you are at the gingivitis stage, which most people are. That is the whole intervention.

Between visits, the work is yours and it is unglamorous. Brush twice a day for two minutes, angled into the gum line rather than straight at the tooth. Clean between the teeth once a day with floss or interdental brushes, because a brush does not reach the surfaces between teeth and that is where gum disease usually starts. Expect a little bleeding for the first few days if you have not been doing it. Expect it to stop. If it has not stopped after two weeks of doing it properly, that is the point to have someone look.

When bleeding is not about plaque

Plaque explains the large majority of bleeding gums, but not all of it. Pregnancy raises how strongly gums react to the same amount of plaque. Some blood thinning medicines make gums bleed more readily. Poorly controlled diabetes and gum disease feed each other in both directions. Smoking, including shisha, does something worse than cause bleeding: it reduces it, by narrowing the small blood vessels, so smokers often have advanced gum disease with tidy looking gums that never bled at all.

None of those replace the clean. They change how often it needs doing, and they are worth mentioning when you come in.

If your gums have bled for years and nothing has happened yet, that is not evidence that nothing will. It is the nature of the condition. A look and a clean take one appointment, and if your gums are fine we will tell you that and send you home. You are welcome to get in touch if you would rather ask first.

Common questions

Should I stop brushing the area that bleeds?

No. That is the worst thing to do. Plaque builds up further and the bleeding gets worse. Brush it gently and thoroughly, and have the tartar removed.

My gums bled when I started flossing. Is that normal?

For the first few days it is common, because the gum between the teeth is already inflamed. It should settle within a week or two of daily flossing. If it does not, come and have it looked at.

Will mouthwash stop my gums bleeding?

It can reduce the inflammation for a while and mask the smell, but it does not remove tartar. Nothing you can buy removes tartar. Only scaling does.

Does scaling damage the enamel or loosen teeth?

No. The instruments remove hardened deposits, not tooth. Teeth can feel slightly odd for a day or two because tartar that was wedged between them is gone, and gaps that were already there become noticeable.

Can I have a scaling appointment while fasting in Ramadan?

Yes. Water and paste are suctioned out as we work, though some people prefer to book after iftar. Our evening slots run to 9pm Monday to Friday.

How often should scaling be done?

Once or twice a year suits most people. Heavy tea, coffee or tobacco use, or a history of gum disease, means more often. You will be told what your mouth needs, not sold a schedule.
