###Human: My mouth is always filled with saliva. What can I do now? ###Assistant: Hi. Excessive saliva production or hypersalivation can occur due to two reasons. It occurs due to an increased saliva production and due to reduced swallowing of saliva. Saliva overproduction can occur due to many causes like oral and throat infections, oral ulcers, acid reflux, excess starch consumption, due to a side effect of medication like Clonazepam, Pilocarpine, Ketamine, a toxin exposure, and serotonin syndrome. Decreased swallowing can occur due to throat pain caused by the infection, tonsillitis, and nerve damage. You should consult an oral physician and get evaluated. A thorough checkup will help in confirming the cause and treatment of the cause will solve the problem. As of now, you can use mouthwash frequently and brushing the teeth has a drying effect in the mouth.
