Dental Visit
互動天地
作者：By Karen Zhang
It’s a fact that many people pay little attention to their teeth until they feel discomfort. I’m one of them. My gums[牙齦] bled[出血，流血] a bit when I brushed my teeth. So， this spring I visited my dentist—my first time in America when asked how long it’d been since I’d seen a dentist， I said it was at least a decade. My answer would have shocked my dentist， as Americans are recommended to have a dental visit every six months.
After my dentist examined my oral X-rays， she said without hesitation， “You have gum disease. You need a deep cleaning.” Seeing me looking bewildered[使迷惑，使難住]， she explained，“We’ll numb[使麻木] your gums and then clean your teeth. We’ll see how it goes from there.”Off she went. （After having me wait for her for nearly an hour， she only saw me for less than ten minutes. It’s not uncommon for a doctor’s visit in America.）
I returned to the dentist’s office two weeks later as scheduled for a deep cleaning appointment. This time， I was greeted by a dental hygienist right away. I overheard[無意中聽到] his name is George. Probably George had seen nervousness on my face， he tried to tell jokes to relax me while getting me prepared. He was no doubt less stiff than the dentists I saw in China.
As my mouth was getting numb， I felt like my face was swollen[腫脹]. Lying on a reclining chair[躺椅]， face up， I had no idea what George was doing in my mouth. With a seemingly long and pointy metal tool in his hand， he was preoccupied with what he was doing. I learned later that the tool he used is called an ultrasonic scaler[超聲波除垢器]， which vibrates at a frequency that breaks down dental tartar[牙垢] on the surfaces of one’s teeth.
