Drooling in developmentally normal children: a review

Drooling or saliva spillage has been explored widely among children with neurodevelopmental conditions. Yet, the approach to drooling in an otherwise developmentally normal child remains unexplored, as it is regarded as self-limiting. Nonetheless, drooling beyond age 4 in the awake stage should raise concern.

This narrative review aims to shed light on drooling in developmentally normal children, also known as 'healthy droolers', and the available evidence on its management.

Most notable factors causing saliva spillage include poor oral-motor control and impaired oral sensation. Delayed saliva acquisition may be an early indicator of developmental or intellectual delay. Drooling impairs both the children's and parents' overall quality of life significantly.

Healthy droolers can be managed by simple behavioural therapy and reassurance.
