I seem to produce too much saliva. Every time I wake up, my mouth is full of saliva, and I have to spit it out every few minutes during the day. It gets a little better after brushing my teeth, but the problem continues. What could be causing this?

Excessive saliva production, also known as hypersalivation, can have various causes such as medication side effects, GERD, infections, or neurological conditions. In your case, since the issue improves after brushing, it could be related to oral hygiene. I recommend using a mouthwash containing chlorhexidine gluconate 0.12% solution twice daily after brushing. Additionally, you can try using tablets containing atropine sulfate 0.5mg to reduce saliva production. If the problem persists, consult with your healthcare provider for further evaluation and management.
