7 Causes of Gum Bleeding

Bleeding of gums is a common problem. However, it should not be brushed aside as something insignificant. Most people notice the blood when they spit or rinse their mouth after brushing or while examining their teeth after flossing.

The hint of red near the gum line or in the sink is proof enough that you need to speak to your dentist in Hope Island. Although it may not be a serious condition and could be caused by the wrong brushing technique, you can get it examined to rule out ailments like periodontitis.

There are several causes of gum bleeding, and you must be aware of them to act in time and avoid unnecessary pain and treatment expense. Let us take a look at them.

1. Gingivitis

One of the prominent reasons for gum bleeding is gingivitis, which is nothing but inflammation of the gums. However, it is not a serious condition and only a minor ailment caused by the accumulation of plaque near the gum line.

The growth of bacteria close to the gums leads to infection of the gum. It causes swelling and redness. So, when the bristles of the brush stroke against the inflamed gums, it causes bleeding.

However, this is just the beginning of gum disease, and it must be nipped in the bud to avoid deterioration. The cause of gingivitis is poor oral hygiene. Thus, make sure that you brush in the right manner twice a day and floss regularly to keep plaque away.

 2. Diabetes

High blood sugar levels increase the amount of sugar present in saliva that surrounds our teeth and gums. The presence of excessive sugar becomes a breeding ground for bacteria that leads to plaque. As stated above, the accumulated plaque inflames gums and causes bleeding.

Also, diabetes reduces the ability of the body to fight infection, which can aggravate the problem. Thus, the dentist may ask you to get your blood sugar level tested after examining your teeth to get a clear picture.

 3. Imbalanced Diet

Few people are aware of this, but a poor diet can also lead to gum problems, such as scurvy. Deficiency of vitamin C leads to this ailment that causes bleeding of gums, exhaustion, weakness, blurry vision, and tooth loss.

It usually occurs in people who have a limited diet due to an eating disorder or a lifestyle habit. Vitamin K deficiency could also cause gum bleeding as it restricts blood clotting.

In such cases, even a small abrasion from the toothbrush can lead to the overflow of blood. So, make sure that you eat a healthy and balanced diet consisting of the required minerals, vitamins, and proteins.

4. Periodontitis

Periodontitis is caused when gingivitis goes untreated. The long-term presence of plaque on the tooth and gum line erodes the surrounding tissue and bone that holds the tooth in place. Periodontitis makes the gums pull away from the tooth, which makes them loose and vulnerable to bleeding easily.

It can also cause bad breath, swollen gums and leaves a bitter taste in the mouth. You may also notice a different chewing pattern. So, visit your dentist every six months to get your teeth examined before the condition worsens.

5. Pregnancy

Bleeding of gums could also be due to pregnancy as the hormonal changes make the gums susceptible to plaque, which causes gingivitis. During pregnancy, there is an increased flow of blood in the mucous membranes and lesser production of saliva in the mouth.

The sugar from food stays in the mouth for a long time and gives birth to plaque. Thus, its often referred to as pregnancy gingivitis. It is a mild ailment, but you must visit your dentist when you witness bleeding to get it checked and treated in time.

Some women feel nauseated by the smell of toothpaste because of the heightened sense of smell and avoid brushing twice a day. It can also lead to gingivitis. So, make sure that you take extra care of your oral health when you are expecting.

6. New Toothbrush

Sometimes buying the wrong toothbrush can lead to gum bleeding as the hard bristles can scrape your gums. Also, some people may use too much force while brushing that can cause bleeding. Brushing vigorously does not help in removing bacteria.

It only causes gum recession and inflammation. Thus, if the reason for bleeding gums is your toothbrush, make sure to replace it and change your brushing technique. The brush should be moved in soft circular motions without hurting the gum. You can opt for a soft-bristled toothbrush if the regular one is triggering the trouble.

7. Blood-Thinning Medication

People who are taking blood-thinning medication can bleed easily through small cuts and abrasions. The medicine diminishes the natural blood clotting tendency of the human body and causes easy discharge even after small cuts. Also, those who wear dentures that are ill-fitted can lead to inflammation.

Blood thinners can pose a problem when you are going for dental treatment as they can cause much more bleeding than expected. Thus, make sure that you inform your dentist about your health conditions and medications to understand gum bleeding.


It is significant to identify the underlying problem behind bleeding of gums to stop it from worsening. It is also vital in recognising other health issues, such as diabetes, scurvy, or leukemia. Thus, book an appointment with your dentist in Hope Island when you notice bleeding of the gums.
