Saliva helps in the digestion of food, keeps your mouth clean by flushing the debris, aids in speech, keeps your mouth moist and fights infection because of its antibacterial properties. Your salivary glands produce close to 1-1.5 liters of saliva daily. However, sometimes people can have excessive saliva in their mouths. Excessive salivation is called ‘Hypersalivation’ or ’Sialorrhea’. Increased salivation beyond the margin of your lips is the cause for drooling.

Temporary hypersalivation can be seen in conditions like pregnancy, teething, dental cavities and infections, use of dentures.

Medications. Certain drugs are known to reduce saliva production. These meds are anticholinergic drugs ( These drugs block the nerve innervation to the salivary glands and reduce the production of saliva)

Injections. Your doctor may recommend Botox injections. The botox toxin is injected to one or more major saliva glands. This toxin paralyses the nerves and muscles in the area, preventing the production of saliva from the glands.The effect may last upto 5 months.

Radiation therapy. Radiation of the salivary glands causes xerostomia ( Dry mouth ). This is the treatment of choice in the elderly who cannot undergo surgery.

Surgery. In sever cases of drooling, surgery of the salivary glands has shown good results. Your doctor can decide to remove the salivary gland or redirect the salivary duct. The most successful options includes ligating the parotid gland duct ( Gland in front of the ear ) and excision of the submandibular gland ( Gland in the mouth under the tongue ).
