Botox can prevent drooling, particularly when it's becoming a health concern.
Drooling is common among people with Parkinson's disease, a nervous system disorder that causes tremors and slow, imprecise movement. Verywell Health reported up to 78% of people with Parkinson's say they drool, possibly because the disease can make swallowing more challenging.
Kids, too, can drool too much before oral-motor function is fully developed, per Royal Children's Hospital in the Australia.
Aside from being uncomfortable and causing embarrassment, excess drooling can cause skin irritation, bad breath, and even pneumonia if accidentally ingested.
For this application, a doctor injects Botox directly into the salivary glands to stop them from producing too much saliva, Verywell Health reported. The procedure is minimally invasive, but it might cause dry mouth and only lasts three to four months.
