Why Is There Blood in My Mouth After Waking Up?

Waking up with blood in saliva may indicate periodontal disease, gingivitis, or other conditions. It is necessary to visit the hospital promptly to determine the cause and receive targeted treatment.

The most common cause of waking up with blood in saliva is periodontal disease. Typically, large amounts of dental calculus and dental plaque accumulate around the gums, leading to gingival bleeding, especially when brushing teeth. Bleeding is more likely to occur in the early morning and may be observed in saliva. Removing dental calculus can help improve the condition. Methods such as ultrasonic scaling and subgingival scaling can be used to remove dental calculus and irrigate the area. Application of iodoglycerin or minocycline hydrochloride can promote the adhesion of gums to the tooth surface, preventing further bleeding.

Bleeding in the mouth can occur not only in the morning when spitting saliva but also when brushing teeth or eating apples. Most of these cases are related to gingival congestion, which is often defined as a symptom of gingivitis. The inflammatory state can cause local redness and swelling, and slight stimulation such as eating apples, brushing teeth, or rinsing the mouth in the morning can cause microvessels and capillaries to rupture and bleed. However, this usually does not pose a significant risk.

If you notice blood in your saliva after waking up, it is important to carefully observe your oral cavity and seek consultation from a dentist as soon as possible to clarify the condition and avoid delay in treatment. Ignoring this symptom can lead to further exacerbation and have a serious impact on the treatment of the underlying disease.
