It was considerate that George had me put on a pair of dark glasses to dim[使暗淡] the bright operating light above my face. Just when I wondered how to gargle[漱口] in my mouth， as there was no water or mini bowl attached to the chair， George put an electric-powered tube into my mouth and said， “Close your mouth， open.”I followed. After a few tries， I realized this noisy tube was like a vacuum[真空] cleaner， cleaning my mouth for George’s meticulous[一絲不苟的] procedure.
“You’ve been brave，” he praised now and then. Finally， after an hour or so， his job was done！ Before I departed from that frightful chair， George showed me how to properly brush and floss[潔牙線]. Flossing is new to me， ’cause as I always thought brushing my teeth was enough. But flossing is truly essential to prevent gum disease.
Yes， if you haven’t done so， start now！ You
should practice good oral hygiene[衛生] every day by brushing and flossing， and don’t forget to have a dental visit periodically and soon！
