While saliva is usually clear or slightly cloudy, white saliva isn't automatically abnormal. It often depends on the consistency and accompanying symptoms. Thick, white saliva can indicate a problem, such as oral thrush (candidiasis), a yeast infection appearing as white patches in the mouth. This is more common in individuals with diabetes due to higher sugar levels in saliva promoting yeast growth. [Source 1, 2] However, simply observing white saliva isn't sufficient for diagnosis.
What Can Cause White or Thick Saliva?
Several factors can contribute to saliva appearing white or thicker than usual:
- Oral Thrush (Candidiasis): A yeast infection causing white patches and thick, white saliva. [Source 1, 2, 7]
- Dehydration: Lack of sufficient water intake can lead to thicker saliva due to the body conserving water. [Source 3]
Other factors, while not directly resulting in white saliva, can impact its consistency and should be considered if you have concerns:
- Dry Mouth (Xerostomia): Dry mouth can make saliva appear thicker and more viscous. [Source 2]
- Certain Medications: Some medications have dry mouth as a side effect.
When to Seek Medical Attention
If your saliva is consistently white, thick, or accompanied by other symptoms like:
- Pain or discomfort in your mouth.
- White patches on your tongue or in your mouth.
- Difficulty swallowing.
- Fever.
It's crucial to consult a doctor or dentist for proper diagnosis and treatment.
