Should you brush teeth on plane?

Food debris and sugary foods are the primary causes of plaque build-up in your mouth. If you are flying frequently, it won't be long before it leads to gingivitis (or periodontitis). For even longer flights (think Canada to Singapore, Australia, or China), it's advisable to brush twice on the plane.

Stay Hydrated Airplane cabins are usually quite low in humidity — almost to an uncomfortable degree. If you want to feel your best once you land, make sure to keep yourself hydrated by drinking lots of water during the flight.

Clean your skin.
If not, it'll have an even harder time breathing than it already is (thanks, stale, recirculated airplane air) and the hydrating products you apply won't sink in as much as they could. I'd also recommend not washing your face in the airplane bathroom if you can avoid it.
