Suppressing the Gag Reflex
The gag reflex can cause a patient considerable discomfort as well as interfere with dental procedures. An electrolyte tablet administered and retained intraorally a few minutes before the start of a procedure can suppress the gag reflex, allowing a mandibular block to be given with much greater ease, which further reduces the gagging reflex.
Tablets can be prescribed for home use for patients who can not properly perform oral hygiene procedures due to the gagging problem. Severe gaggers may need to repeat a dose in 15 to 20 minutes. (Dent Today. 1991 Dec;10(9):68-71)
Some patients and dentists prefer to use electrolyte lollipops.
