Why Is My Saliva Foamy?
Foamy saliva, also known as frothy saliva, is often a symptom of underlying medical conditions or habits. While sometimes harmless, it's important to understand the potential causes.
Several factors can contribute to the development of foamy saliva. These include:
-
Dry Mouth (Xerostomia): This is a very common cause. When your mouth doesn't produce enough saliva, the existing saliva becomes more concentrated, leading to foam formation. Dehydration is a frequent trigger for dry mouth. [Source: What Causes Foamy Saliva? Foamy spit is usually the result of dry mouth.

When to Seek Medical Attention
