Why Are My Gums Bleeding?

It’s not uncommon to spit blood when you’re brushing your teeth. When you brush or floss too hard you might accidently cut your gums and cause them to bleed. But, if you’re regularly spitting blood when you brush, it might be a sign that something’s not right. If you’ve noticed that your gums bleed regular, here are a few common causes of bleeding that you might relate to:

Bad brushing technique

If you tend to finish your oral health routine with your gums feeling tender and bleeding, then there is a good chance that you are brushing your teeth too hard. Pressing your toothbrush too hard into your gums or using vigorous back and forth motions will irritate your gums, causing them to bleed and, after a while, recede. To prevent this from happening, purchase a soft bristled brush and use gentle, circular motions over your teeth and gums to massage them clean and reach into the gaps between your teeth. If you find it difficult to adjust your technique,  consider switching to an electric toothbrush from our best electric toothbrush options. Electric toothbrushes don’t require you to move the brushes around very much to clean your teeth and will give you a more effective clean.


Gingivitis is one of the most serious causes of bleeding gums. When the plaque on your teeth hardens into tartar and starts to dig beneath the gum line, it can cause your gums to become swollen, sore and, in the later stages, your gums will bleed. Smoking, a bad diet and poor oral hygiene can all contribute to gum disease, so make sure to ditch the bad habits and clean your teeth regularly and thoroughly. Be sure to also pay regular visits to your dentist to have your teeth checked for gum disease and cleaned if necessary.

Ill-fitting dentures and implants

Ill-fitting dentures and partial dentures might move around your mouth and rub against your gums when you wear them. Over time they can severely damage your gums, causing them to bleed, and even erode the bone under the gums. Implants are also capable of causing your gums to bleed if there are any complications. Peri-implantitis is an inflammatory disease that can affect some people with implants. A bacterial infection is accompanied by bone loss and the early stage of this disease, known as peri-implant mucositis, is marked by swollen and bleeding gums. If you wear dentures or have implants and notice bleeding gums, consult your dentist as soon as possible to identify and put a stop to the cause.


Certain types of medication, particularly blood thinning medications, can lead to bleeding gums. These medications inhibit the blood’s ability to clot, which means that you will bleed easier. While this isn’t particularly a problem, it can be worrisome for some people, so be sure to speak with your doctor if your prescribed medications are causing issues. You can also speak to your dentist about the medication you are currently using and they may be able to offer you advice for keeping your gums healthy. There are many great oral health products that are designed to strengthen your gums and prevent bleeding.
