Cleaning the Mouth:

Proper hygiene through brushing your teeth and rinsing your mouth with mouth-wash can temporarily dry out the mouth, and relieve excessive mouth watering.


A watery mouth causes a lot of irritation that may require therapy. Therapy will help patients by enlightening them on techniques such as lip closure, posture, head control, swallowing, and better tongue control.

Administering Cuvposa Medication:

Cuvposa or Glycopyrrolate helps reduce excessive mouth watering by blocking nerve impulses to the salivary glands, inhibiting the production of saliva. This, however, can bring about some side effects such as a dry mouth, urinating problems, and constipation.

Botox Injections:

A doctor may inject Botulinum toxin as known as Botox into one or more of the salivary glands. This drug causes the nerves and muscles around that area to get paralysed preventing the production of saliva.

It is essential to note that this drug wears off after some time. It is therefore essential to seek additional injections if suffering from excessive mouth watering.
