Drooling or dribbling is the unintentional loss of saliva from the mouth.
It occurs in infants, but as the infant gets older it usually decreases. Daytime drooling stops within the first few years. Older children may still drool during sleep. Beyond the age of about 4 years, it's unusual, unless there is an underlying medical reason.
A variety of techniques can treat drooling. Some are more successful than others, but treatment will depend upon the individual. You will need an ear, nose and throat examination before choosing a treatment.
Treatments can include:
rewarding or prompting to encourage swallowing
exercises to increase muscle tone, improve oral-motor function and sensory awareness
