Sialorrhea (Drooling)

Sialorrhea is the medical term for excessive drooling that continues beyond the typical age when children learn to control their saliva. It often happens because a child has difficulty managing saliva in the mouth, rather than producing too much of it. Sialorrhea is more common in children with neurological or developmental conditions, but it can affect any child and may impact comfort, skin health and daily activities.

Sialorrhea can have several causes related to how a child controls saliva and uses the muscles of the mouth and face, including:

• Neurological or developmental conditions that affect muscle control and swallowing
• Oral‑motor dysfunction, such as weak or poorly coordinated mouth muscles
• Dental or oral health issues, including tooth alignment problems or mouth discomfort

Some children are more likely to experience sialorrhea due to conditions that affect muscle control, development or coordination, including:

• Children with cerebral palsy, who may have difficulty controlling the muscles used for swallowing
• Children with developmental delays, which can affect oral‑motor skills
• Children with certain genetic or neurological syndromes that impact saliva control and swallowing

Symptoms of sialorrhea are related to ongoing drooling and how it affects a child’s comfort and daily life, including:

• Persistent drooling beyond the typical developmental age
• Skin irritation or rashes around the mouth, chin, or neck caused by constant moisture
• Wet clothing or bibs, which may require frequent changes throughout the day

Sialorrhea is usually diagnosed based on a child’s symptoms and a medical evaluation to understand what may be affecting saliva control, including:

• Review of medical history, including drooling patterns and any underlying neurological or developmental conditions
• Physical and oral examination to assess muscle control, swallowing ability and mouth structure
• Evaluation by specialists to help identify contributing factors and guide treatment options

Treatment for sialorrhea depends on the child’s age, underlying cause and how much drooling affects daily life, and may include one or more of the following options:

• Therapy and skill‑building, such as speech or occupational therapy, to improve oral‑motor control and swallowing
• Supportive measures, including absorbent bibs, clothing protectors and skin‑care routines to prevent irritation
• Dental or oral care, to address issues like tooth alignment or mouth discomfort that can worsen drooling
• Medications, which may be used in some children to help reduce saliva production when drooling is significant
• Medical procedures, such as injections to reduce saliva flow, in certain cases
• Surgery, which may be considered for severe or persistent sialorrhea when other treatments have not been effective and is carefully evaluated by specialists

A child’s healthcare provider can help determine the most appropriate treatment plan based on the child’s individual needs.

Managing sialorrhea often involves simple strategies and supportive care to reduce drooling and improve your child’s comfort and daily life, such as:

• Working with healthcare specialists to address oral‑motor skills and swallowing
• Using practical supports, such as absorbent bibs, clothing protectors or skin barriers, to keep skin dry and protected
• Encouraging good oral habits, including regular swallowing reminders when appropriate for your child’s age and ability
• Maintaining healthy skin care, by gently cleaning and moisturizing areas affected by drooling
• Discussing treatment options with your child’s care team if drooling is persistent or significantly affecting quality of life
