  • Chest X-ray
  • Cone beam CT
  • Sialography

Treatment of dryness of mouth not only depends on treating the underlying cause but also managing the complications associated with dry mouth.

What is Drooling/Excessive salivation?

Drooling occurs when saliva goes beyond the margins of the lips. Drooling caused by increase in salivary flow is termed Sialorrhoea or Ptyalism.

Drooling can result of the result of either an increase in saliva production or a decrease in salivary clearance

Some of the causes of drooling include

  • Gastroesophageal reflux disease
  • Infant teething
  • Local irritations
  • An ill-fitting appliance
  • Certain medications
  • Heavy metal poisoning
  • Neurologic changes such as in a cerebral vascular accident (CVA), neuromuscular diseases
  • Idiopathic paroxysmal hypersalivation

Excessive salivation can result in

  • drooling and choking which can produce social embarrassment
  • aspiration pneumonia
  • bad breath
  • macerated sores around the mouth and chin that can get secondary bacterial or fungal infection
  • constant soiling of clothes and bed linens

How is Drooling managed?

Management of drooling includes thorough clinical examination to determine the underlying cause of hypersalivation if present

Some of the investigations could include

  • Sialometry
  • Nasopharyngoscopy
  • Radiography
  • MRI
  • Barium swallow
  • Sialography
  • Psychological assessment

Management of excessive salivation could include oral motor training, behavior therapies and medications that reduce the production of saliva.
