Saliva is secreted from the salivary glands in the mouth. The main salivary glands are the parotid, sublingual, and submandibular glands. Saliva not only keeps the mouth moist, but also aids in digestion, controls bacteria in the mouth, and has other functions, according to the health website Healthline (USA).
Gingivitis can cause bloody saliva.
Changes in the color and texture of your saliva can be a sign of something wrong. If you notice blood in your saliva, especially after brushing your teeth, it could be a sign of gingivitis or periodontitis.
Inflamed or bleeding gums can also mean that bacteria are entering the bloodstream. Yellow saliva can be due to phlegm. Yellow phlegm is a sign that the respiratory tract is infected with bacteria or viruses.
Thick, white saliva and white patches in the mouth are signs of a yeast infection, also known as thrush. Thrush is caused by an overgrowth of the yeast candida albicans in the mouth.
If your saliva has a normal color and texture (clear and thin) but your mouth often has a sour taste, especially after you have cleaned your teeth thoroughly, it could be a sign of gastroesophageal reflux. If this condition persists, you should see a doctor for timely examination and treatment, according to Healthline .
