Post-nasal drip or a nosebleed are also likely sources of blood in the mouth upon waking. If the nasal passages become irritated, blood can drip into the mouth, resulting in blood in the saliva. Coughing while asleep can also result in blood from the lungs or gastrointestinal tract making its way into the mouth.
Certain narcotics, such as crystal meth, result in oral lesions that might bleed overnight. Some medications might also cause the gums and other oral tissues to bleed, which is why it is important to discuss this symptom with a physician, according to HealthHype.
