Excessive Salivation

Rather than an over production of saliva, excessive salivation (or drooling) is likely the result of an accumulation of saliva in the mouth due to less frequent swallowing. Feedback therapies along with speech therapy to encourage more frequent swallowing of the saliva is often helpful. If the drooling becomes severe, drops of ophthalmic solutions of atropine under the tongue are helpful.
