White saliva at the corner of your mouth may indicate that the saliva is becoming thicker or drying out, which can be a sign of irritation or even a yeast infection like Candida that can lead to angular cheilitis.
When you see white saliva collecting in the corner of your mouth, it could mean that your saliva is thick and not moving as quickly. Normally, saliva is clear and watery, but sometimes changes in your mouth can make it thicker. This may happen if the area is dry or irritated, so the saliva takes on a white appearance as it collects and begins to dry. In some cases, white saliva can be connected with angular cheilitis, a condition where the skin at the corners of the mouth becomes sore and cracked. Angular cheilitis can happen when a yeast called Candida grows in the area, especially if the saliva does not clear away properly. Changes in the makeup of your saliva may also be a clue that something is affecting your salivary glands and mouth health. If you notice white saliva along with redness, soreness, or cracks at the corners of your mouth, it might be a good idea to talk with a healthcare provider. They can check for infections or other issues and suggest the right treatment to help clear it up.
