Gingivitis

Early, reversible inflammation of the gums, usually caused by plaque building up along the gum line.

This page is general information, not a diagnosis or treatment recommendation. For advice about your own teeth, or your child's, please speak to a dentist.

What gingivitis is

Gingivitis is inflammation of the gums, and it is the earliest and mildest form of gum disease. It is usually caused by plaque, the sticky film of bacteria that builds up along the gum line when it is not removed by brushing and cleaning between the teeth. The good news is that at this stage it is generally reversible.

Because the early signs can be easy to overlook, gingivitis is often noticed at a check-up. Spotting it early and acting on it is the simplest way to keep it from progressing.

Signs to look for

Healthy gums tend to look firm and pale pink and do not usually bleed with normal brushing. With gingivitis, the gums may become red, puffy or tender, and they often bleed when brushing or cleaning between the teeth. Bad breath can sometimes be associated with it too.

Common signs

  • Red, swollen or tender gums
  • Bleeding when brushing or cleaning between the teeth
  • Gums that look puffy rather than firm

How it's managed

Gingivitis can often be brought under control with a professional clean to remove plaque and hardened deposits, combined with good daily oral hygiene at home. A dentist or hygienist can show you techniques for brushing and cleaning between the teeth that suit your mouth.

Left unmanaged, gingivitis can in some people progress to a more advanced form of gum disease called periodontitis, which affects the deeper supporting tissues and is harder to reverse. That is why bleeding or inflamed gums are worth attending to rather than ignoring. A dentist can assess what is needed.

What can make gums more prone to it

Plaque is the main driver of gingivitis, but several things can make a person more prone to it or make it harder to control. Smoking, some general health conditions such as diabetes, certain medications, and hormonal changes, for example during pregnancy, can all play a part.

These factors do not cause gingivitis on their own, but they can tip the balance, which is why a dentist looks at the wider picture rather than at the gums in isolation. Where one of these factors is relevant, it can be taken into account in the advice given.

Things that can make gums more vulnerable

  • Smoking
  • Some health conditions, such as diabetes
  • Hormonal changes, for example during pregnancy
  • Plaque that is hard to remove around crowded teeth or dental work

Preventing gingivitis

Because gingivitis is driven by plaque, the most effective prevention is removing plaque thoroughly and regularly: brushing twice a day, cleaning between the teeth daily, and having professional cleanings as advised. A dentist or hygienist can show you techniques suited to your mouth.

Keeping up routine check-ups also means any early inflammation is spotted and dealt with before it has a chance to progress. Healthy gums are easier to keep healthy than to restore, so consistent daily care is the foundation.

Questions & answers

Gingivitis: common questions

Is bleeding when I brush normal?
Gums that bleed when brushing or cleaning between the teeth are a common sign of gingivitis and are worth attending to, rather than something to ignore. Healthy gums do not usually bleed with normal brushing. A dentist can check what is causing it and advise.
Can gingivitis be reversed?
At this early stage gingivitis can often be brought under control and reversed with a professional clean and good daily oral hygiene. Acting early matters, because if it progresses to more advanced gum disease the changes become harder to reverse. A dentist can advise on the right steps.
What is the difference between gingivitis and periodontitis?
Gingivitis is early, usually reversible inflammation of the gums, while periodontitis is a more advanced form of gum disease that affects the deeper tissues and bone supporting the teeth. Gingivitis can progress to periodontitis if not managed, which is why early care is worthwhile.
