Last summer, I got braces and tonight I had to get a checkup at the dentist. This isn’t the first time though, since I have to get a checkup every three weeks. Normally, Dr. Guo just changes the rubber bands around the transparent brackets. As usual, he just did that. However, when I arrived home, my teeth were aching very badly. It seemed that Dr. Guo used a stronger kind of rubber band than before. I thought “why do I have to check my teeth before my midterm?” Nevertheless, all I could do was hope that my teeth would not affect my spirit and make me all grumpy, which is definitely not good for my preparation for the upcoming tests.
