It has probably happened to you at some point: you are brushing your teeth in front of the mirror, you spit out the toothpaste and notice a pinkish tinge, or even a thin trickle of blood.
The usual reaction is to think “I must have brushed too hard”, or simply to ignore it because it does not hurt.
At our clinic we see patients every day who have come to accept this symptom as normal, living with it for months or years. But we always insist on one fundamental idea: healthy gums do not bleed, just as your hands do not bleed when you wash them.
Gingivitis should not be seen as a terrifying disease, but as your body’s own alarm system. It is warning you that something is not right and needs attention before the problem gets complicated.
What exactly is gingivitis? (And how to recognise it)
Put simply, gingivitis is the superficial inflammation of the gum caused by a build-up of plaque and food debris that daily brushing has not managed to remove.
When bacteria build up along the line where the gum meets the tooth, the body reacts by sending blood to the area to defend itself: that is what causes the swelling and bleeding.
What does an unhealthy gum look like?
It is easy to spot with the naked eye if you know what to look for. A healthy gum is pale pink (coral pink) with a firm, stippled texture, rather like orange peel.
With gingivitis, on the other hand, the gum loses that firmness: it becomes red, shiny and swollen and bleeds at the slightest touch.
Patients sometimes come in worried about changes in colour, such as dark patches or white gums, but paradoxically a bright, intense red is the clearest clinical sign of active inflammation caused by bacteria that we need to treat.
Symptoms: how to identify gingivitis
The most treacherous thing about gingivitis is that, unlike deep decay or a fracture, it does not usually cause sharp pain in its early stages. That is why many patients let time pass, thinking the problem will go away on its own.
Your mouth, however, sends clear signals long before real pain appears. At our dental clinic in Alicante we always ask patients to watch for these four warning signs:
- Frequent bleeding: the number one symptom. It can appear when you brush, when you floss or, in more advanced cases, spontaneously when biting hard foods such as an apple.
Remember: just because it does not hurt does not mean it is normal.
- Swelling and changes in shape: when the gum becomes inflamed, it swells and loses its sharp edge. This often creates a curious optical effect: your teeth seem shorter or smaller, simply because the swollen gum is covering more enamel than it should.
- Bad breath or a bad taste in the mouth: being an infection caused by bacteria, they release compounds that produce an unpleasant smell (halitosis) or a constant metallic taste that chewing gum and mouthwash cannot shift.
- Tenderness to the touch: although you may not feel a stabbing pain, you will probably notice your gums feel soft or sore if you touch them with your tongue or finger. That tenderness shows the tissue is fighting an infection.
Main causes of gingivitis
Although we sometimes look for complex reasons, the clinical reality is clear: the main cause of gingivitis is a build-up of bacterial plaque.
When we eat, food debris mixes with saliva and bacteria, forming an invisible film on the teeth. If we do not remove it properly by brushing and flossing, this plaque hardens and turns into tartar (calculus).
Once tartar has formed, you can no longer remove it at home; it becomes a rough stone that traps even more bacteria and constantly irritates the gum.
There are, however, factors at play that make some people more prone to it:
- Tobacco: a great enemy because it deceives. By reducing blood flow, smokers’ gums tend to bleed less, hiding the disease until it is very advanced.
- Hormonal changes: during pregnancy, puberty or the menopause, the gums become far more reactive to bacteria.
- Ill-fitting dentures or fillings: if old dental work traps food, the gum in that area will inevitably become inflamed.
What if I have implants? There is a belief that implants, being titanium, cannot get diseased. That is a dangerous mistake.
It is vital to control inflammation not only around natural teeth but also if you have dental implants, since around implants gingivitis (technically called peri-implant mucositis) progresses faster and can put the integration of the post and the durability of the treatment at risk.
Why is it dangerous to leave it untreated?
We often insist so much on treating gingivitis not because of what it is now, but because of what it can turn into if we ignore it.
Gingivitis is a reversible disease; if we clean and treat it, the gum returns to perfect health. But if we do nothing, the infection goes deeper and develops into periodontitis (commonly known as gum disease).
At this stage the damage is irreversible: the bacteria start to destroy the bone that holds the tooth and the periodontal ligament. The gums recede, the teeth look longer and, over time, they start to move and can be lost.
The cosmetic side
Beyond health, inflammation ruins the beauty of the mouth. A beautiful smile starts with pink, healthy gums.
There is no point in complex cosmetic treatments such as veneers or whitening if the gum around those teeth is inflamed, red or bleeding, since the final result will never look clean or harmonious.
Treating and preventing gingivitis
If you have read this far with growing concern, I have excellent news for you: unlike periodontitis (where lost bone does not grow back) or decay (which needs a filling), gingivitis is 100% reversible.
If we act now, we can clear the infection and get your gums back to full health, as if nothing had ever happened.
How do we treat it at the clinic?
Treatment depends on how far the problem has progressed, but our approach is always conservative:
- Professional cleaning: if the tartar is superficial, we do an ultrasonic clean and polish to remove the bacteria and surface stains. It is quick and painless.
- Basic periodontal treatment: if we find that tartar has got below the gum line, a normal clean is not enough. In that case we do a thorough scaling to leave the root of the tooth clean and smooth, allowing the gum to settle down and hug the tooth properly again.
How to prevent gingivitis
To prevent gingivitis (swollen, red, bleeding gums), the most important thing is to control plaque every day and break the vicious circle: plaque → inflammation → bleeding → I stop brushing → the inflammation gets worse.
At home, what really works is consistent, well-done hygiene. Brush 2 to 3 times a day for at least 2 minutes, using a soft brush and a sweeping technique from the gum towards the tooth, working gently along the gum line without pressing. If you use an electric toothbrush, just rest it on the teeth and let it do the work, without scrubbing.
Cleaning between the teeth is key and is often the step that gets neglected. Dental floss is ideal if the spaces are tight, while interdental brushes are usually more effective when there are small gaps.
A water flosser can be a good complement for removing food debris, but it does not replace the methods above. If the gum bleeds when you start, do not stop cleaning that area: it bleeds precisely because there is inflammation and a build-up of plaque.
As for toothpaste, a fluoride toothpaste is enough in most cases. If you are prone to gum inflammation, we can recommend a specific one for your particular situation.
Mouthwash should only be used as a back-up and for a limited time. It never replaces brushing or interdental cleaning.
In more marked cases of gingivitis we sometimes prescribe chlorhexidine for a few days, always on the dentist’s instructions to avoid side effects such as staining or changes in taste.
Do not put off until tomorrow what you can cure today
Our advice as dentists is clear: do not treat bleeding as normal. If your gums bleed, they are asking for help.
Treating gingivitis in time is simple, quick and inexpensive. Waiting until it hurts or the teeth start to move, however, turns the problem into something far more complex and costly to solve. Your health and your peace of mind deserve that preventive care.
