Probiotics Cause Stringy Saliva

Hello everyone. Firstly, I am sorry about my English. I'm not a native English speaker. I have problem taking probiotics. Two days ago, I took probitoics in powder form in my mouth and tougue. And I immediately got thick, foamy and very stringy saliva. It doesn't go away even if I overbrushing my whole mouth. I also use antibacterial mouth wash and It doesn't help. What should I do now? I'm really worried. My saliva used to be watery.Please help me.
My oral health is really bad now. Thank you very much.
