Blood in saliva
The unexpected sight of your own blood can be unsettling. One of the times this can happen is when you spit and see blood in your saliva. Another time you might notice blood in your saliva is when you have a rusty, metallic taste in your mouth.
Let’s take a look at the causes of blood in saliva and how each is treated.
Treatment usually includes a professional dental cleaning followed by good oral hygiene. Later stages of the condition may require surgical treatment.
Also called canker sores, mouth ulcers are small, painful sores that develop on your gums, inside your lips, and inside your cheeks. They’re often triggered by:
- minor injury, such as accidentally biting your cheek
- aggressive brushing
- recent dental work
- diet low in vitamin B-12, folic acid, iron, or zinc
- using toothpastes and mouthwashes with lauryl sulfate
- food sensitivity to spicy or acidic foods
- inflammatory bowel disease (IBD)
- celiac disease
- immune system problems
Treatment for mouth ulcers isn’t typically needed, as they tend to clear on their own. If they grow large or last for more than a couple of weeks, your doctor might recommend prescription mouthwash with dexamethasone or lidocaine.
Over-the-counter (OTC) gels, pastes, or liquids may also help. Options include:
- hydrogen peroxide
- benzocaine (Anbesol, Orabase)
- fluocinonide (Vanos, Lidex)

Cancers that can cause you to have blood in your saliva are:

- Throat cancer. This cancer is characterized by tumors that develop in the pharynx (throat), larynx (voice box), or tonsils.
- Leukemia. This cancer affects the blood and bone marrow.
Your doctor will discuss treatment options tailored to the stage of the cancer, its specific location, the type of cancer, your current health, and a number of other factors. Treatment might include:
