<s>[INST] my father 68 has NOT stopped spitting since he woke up today.. too much saliva. How can he stop this ? [/INST] Hello and welcome, The excessive salivation may be due to-use of denture. Weak buccal muscles which interferes with proper mouth closure. Systemic conditions. Medications. Abscess formation from caries/periodontal infection. I would suggest you to visit a dentist for further evaluation. Maintain good oral hygiene. Anti-sialogogues can be administered if necessary. Medications if any has to be replaced if causing excessive salivation. Hope this helps. </s>
