Arguably, the only
inconvenience related to mouthwash use is the sting. Some can’t
stand the burning sensation whenever they wash their mouth with a
generous helping. While no-sting formulas in the market exist, the
burning sensation is often considered a sign of the mouthwash's
effectiveness.
The dental community is
divided as to what causes the burning sensation with every swish or
gargle with the mouthwash. According to BreathMD.com, the alcohol
content is to blame. This is the more common argument where some
mouthwash
brands contain up to 30 percent alcohol. As a desiccant, alcohol
dries up the mouth, leaving it prone to the slightly bothersome
sting.
