S.D.
My brother was a big drooler. My mother was referred to an ENT and was told that he just had large tonsils. There was no medical need to ever remove his tonsils only because he drooled a bit more than normal. Growing up we all just made him aware when he was drooling and he grew to control it most of the times. From time to time as he got older, when he would talk fast he may have drooled a little but caught it right away. He's a grown man now and I can't remember the last time I saw him drool. I'd say he finally out grew it!
