I had my teeth cleaned 31 days ago,  ever since I have had a sever throat that is now affecting my voice and bad taste in my mouth and tingling burning tongue. He also used a topical  benzocaine 20% liquid on my gums. The liquid dripped down my throat .Katherine
HiT hanks for writing in. As such there is no such relation between sore throat & cleaning. It might be due to endocrine Chat Doctor. In case you have bad taste use 0.2% clothes mouth wash once daily. Visit your dentist for further opinion. Regards
