Drooling Health Article

Definition

Drooling is saliva flowing outside the mouth.

Alternative Names

Salivation

Considerations

Drooling is generally caused by:

• Problems keeping saliva in the mouth
• Problems with swallowing
• Too much saliva production

Some people with drooling problems are at increased risk of breathing saliva, food, or fluids into the lungs. This may cause harm if there is a problem with the body's normal reflexes (such as gagging and coughing).

Drooling caused by nervous system (neurologic) problems can often be managed with drugs that block the action of the chemical messenger, acetylcholine (anticholinergic drugs). In severe cases, people can reduce drooling by injecting botulism toxin, getting high-energy x-rays (radiation) to the glands in the mouth that make saliva (salivary glands), and other methods.

Common Causes

Some drooling in infants and toddlers is normal and is not usually a sign of a disease or other problem. It may occur with teething. Drooling in infants and young children may get worse with upper respiratory infections and nasal allergies.

Drooling that occurs with fever or trouble swallowing may be a sign of a more serious disease, including:

• Mononucleosis
• Peritonsillar abscess
• Retropharyngeal abscess
• Strep throat
• Tonsillitis

Sudden drooling may occur with poisoning (especially by pesticides) or a reaction to snake or insect venom.

Other things that can cause drooling:

• Certain medications
• Nervous system (neurological) problems

Home Care

Care for drooling due to teething includes good oral hygiene. Popsicles or other cold objects (such as frozen bagels) may be helpful. Take care to avoid choking when a child uses any of these objects.

Call your health care provider if

Call your health care provider if:

• The cause of the drooling has not been diagnosed.
• There is concern about aspiration.
• Your child has a fever, difficulty breathing, or holds his or her head in a strange position.
