Doubt it on single application. The material is absorbed/ washed off & swallowed naturally over time. The caution to avoid brushing is to give it enough time on the teeth to provide the most benefit, not that it would be toxic if swallowed.

Your eating, chewing and drinking is enough to remove any excess FLOURIDE gel that wasn't absorbed in teeth. No toxicity will occur but with no brushing, bad breath, and plaque buildup will be present.

There is more risk from not brushing for four days than from fluoride application. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.

Fluoride tretments are exremely safe and well documented over decades of research. No ill efects have ever been documented fromfluoride treatments on adults. Pontetially, the lack of adequate oral home care could cause your much more damage than the fluoride treatment.

None what so ever. There is risk, however, of a bad case of halitosis, especially if you don't floss or WaterPik daily,
