[|Human|] My son has been using Crest Pro Health toothpaste for over a month now and last night after brushing (about 10minutes), he experiences so much salivation that he had to spit constantly all night; hardly got any sleep. He has had the problem all day today and has moved from the front area of his mouth to the back; around his back molars. Could it be a reaction to the toothpaste after several weeks and how will it stop?
[|AI|]  Hello and welcome. The symptoms posted here could be allergic in nature.Therefore, please ask your son to avoid the same toothpaste for time being and look for results. But please keep in mind that if the symptoms persists even after changing the toothpaste then he must report to the dentist. Excessive salivation could be due to other causes too.Therefore, it requires examination. Hope it helps. Thanks. Take care.
