Feeling Saliva on Your Face Without Actual Drooling: Possible Causes

Sometimes there is a sensation of drooling on the face, but when I touch it, it feels dry?

Hello doctor, since last week I have frequently felt a sensation of drooling on my face.
Sometimes it feels like saliva is flowing from the corner of my mouth down to my chin, but when I touch it, it's dry and there's nothing there.
This mainly occurs at the right corner of my mouth, although I occasionally experience this sensation on the left side as well.
What could be the possible factors? Thank you, doctor.

More Info

The sensation of saliva on your face without actual drooling can be quite perplexing and may arise from various underlying causes. This phenomenon is often referred to as "phantom drooling" or "pseudo-salivation." Here are some potential explanations for this sensation:
1. Neurological Factors: The sensation you are experiencing could be related to nerve irritation or dysfunction. Conditions such as Bell's palsy, which affects the facial nerve, can lead to altered sensations in the face, including feelings of moisture or drooling. Similarly, other neurological conditions or even stress and anxiety can cause heightened sensitivity in the facial area.

2. Oral and Dental Issues: Sometimes, dental problems such as gum disease or tooth infections can lead to referred sensations in the face. If there is inflammation or infection in the mouth, it might create a sensation of saliva pooling or dripping, even if there is no actual drooling.

3. Sinus Issues: Sinus infections or allergies can lead to post-nasal drip, which might create a sensation of moisture around the mouth and chin area. This could be particularly relevant if you have experienced any nasal congestion or sinus pressure recently.

4. Psychological Factors: Anxiety and stress can manifest in various physical symptoms, including sensations of moisture or drooling. If you have been feeling anxious or stressed, this could contribute to the sensation you are experiencing.

5. Medication Side Effects: If you are taking any medications, particularly those that affect the nervous system or salivary glands, they could potentially cause altered sensations in the mouth and face. It would be worth reviewing any medications you are currently taking with your healthcare provider.

6. Dermatological Conditions: Certain skin conditions, such as eczema or contact dermatitis, could cause localized sensations of moisture or irritation. If there are any accompanying skin changes, it would be important to consider this possibility.

7. Gastroesophageal Reflux Disease (GERD): In some cases, GERD can lead to increased salivation or a sensation of fluid in the mouth, which might be perceived as drooling. If you have experienced any heartburn or acid reflux symptoms, this could be a contributing factor.

Given that this sensation has been persistent for a week, it would be advisable to consult with a healthcare professional for a thorough evaluation. They may perform a physical examination, review your medical history, and possibly recommend further tests to determine the underlying cause of your symptoms.
In the meantime, keeping a record of any additional symptoms, such as changes in taste, facial weakness, or any other unusual sensations, can be helpful for your healthcare provider in making an accurate diagnosis. Additionally, managing stress and anxiety through relaxation techniques or counseling may also alleviate some of the sensations you are experiencing.

In summary, while the sensation of saliva on your face without actual drooling can be disconcerting, it is essential to consider a range of potential causes, from neurological to psychological factors. A comprehensive evaluation by a healthcare professional will be crucial in identifying the root cause and determining the appropriate course of action.
