What are bleeding gums?

‘Bleeding gums’ might be a sign of gum disease or inflammation. A sufferer of bleeding gums might experience bleeding from their gumline due to the simplest activity e.g., brushing or flossing. At first bleeding gums might be mildly sore and simply a nuisance, but left untreated it can quickly develop into more serious conditions such as periodontitis (which can lead to teeth loosening or even falling out).

If you’re worried about bleeding gums, then it may be worth arranging an appointment with your dentist so they can investigate and provide treatment to resolve the issue.

Symptoms of bleeding gums

In some instances, the bleeding gum might be irritated by the simplest actions e.g., bleeding gums when brushing or flossing, during eating or simply for no reason. Some patients experience some mild discomfort or heightened sensitivity at the affected area.

What is the most common cause of bleeding gums?


One of the most common forms of gum disease where bleeding gums is prevalent is gingivitis. Gingivitis is a form of gum disease that occurs when plaque has accumulated on the gum for a long period of time. If the plaque isn’t removed it can harden and turn into tartar, which can cause further inflammation.

Brushing too hard

Brushing your teeth with excessive force can irritate and inflame the gums by itself. The regularity of your oral health routine is more important than the force you use to undertake it. Furthermore, brushing with a particularly hard brush may also be the cause of bleeding gums. Make sure that you use a soft-bristled toothbrush manufactured by a reputable oral care brand.

Starting to floss

If you’ve just started flossing, then you might be experiencing bleeding gums because your gums aren’t used to receiving such a thorough clean. Bleeding gums should subside a few weeks after starting your flossing regime.


Unfortunately, pregnant women are susceptible to bleeding gums due to a condition called pregnancy gingivitis. Hormonal changes during pregnancy can leave women more vulnerable to plaque, leading to bleeding gums.


In some instances, bleeding gums can be a sign of type 1 or type 2 diabetes. Diabetes can make your mouth more susceptible to gum disease, leading to bleeding gums.


Medication such as blood thinners can cause the gums to bleed more easily. If in doubt, please consult your doctor in regard to your medication and possible side effects.

Poor dental restorations

Faulty, damaged, or very old dentures can cause bleeding gums and become uncomfortable. If you suspect that your dentures are causing bleeding gums, you should arrange an appointment with your dentist so that they can inspect the denture and advise if the dentures need repairing or replacing.

How do you fix and prevent bleeding gums?

The most powerful and effective way to combat bleeding gums is to maintain a regular oral health regime.

Brush regularly

Regularly brushing teeth twice a day with the correct technique, regularly flossing teeth (or using interdental brushes) and attending bi-annual dental check-ups should help protect and prevent against bleeding gums.

Soft-bristled toothbrush

As previously mentioned, using a soft bristled toothbrush from a reputable manufacturer is another way to protect against bleeding gums.

Electric toothbrush

Furthermore, you may decide to opt for an electric toothbrush which can help better clean your gum line compared to a manual toothbrush.
