Hello Lybrate user. Although excessive saliva is not too common, there are a number of conditions that can cause it - some harmless, others more serious. It is possible that your saliva problems are just a result of the way you speak. Some people speak faster or slower than others, just as some people blink more often, breathe faster, or have a more rapid heartbeat. Kindly consult a dentist in person for further suggestion. We need more investigations with clinical examination to decide upon treatment.
