Drooling is defined as the unintentional flow of saliva out of the mouth or to the back of the pharynx due to salivary control problems and swallowing difficulties. Drooling is caused by posture, oral sensori-motor and cognitive problems, and medical symptoms. Treatments of drooling are defined under two criteria: 1) non-invasive treatment, which includes posture and oral motor therapy, and 2) invasive treatment, including botox injection and surgery.Drooling treatment should be initiated non-invasively and in a step-wise manner in all individuals. This mode of treatment is safe, age-free, and is considered the first line of therapy, before subjecting to invasive treatment.Clinical professionals provide non-invasive treatment via manual approaches, through passive sensori-motor stimulation to active oral motor activities. Comprehensive therapy protocols such as oral motor facilitation technique (OMFT) for oral sensory normalization, head and neck postural control, and oral motor function improvements, are required to help control drooling. Clinical professionals therefore need to deeply understand the reason for drooling, and provide qualified non-invasive treatment for intensifying drooling control.
