Saliva production takes a hit due to certain conditions and patient experiences 'Dry mouth'. Dryness of the mouth leads to burning sensation of the mouth, chronic irritation and pain. Absence of saliva may lead to increased incidence of dental caries. Salivary substitutes are agents which moisten the oral cavity and provides lubrication. They usually contain inert agents such as Cellulose or Glycerin which stimulate saliva production. Also, salivary substitutes may contain Biotene or Salagen which are known to boost saliva production. These saliva substitutes helps the patient to chew, swallow and stay comfortable without the dryness or burning sensation.
