부자강
치아도 하얘지는 느낌이라니 신기하네요
I'm using an oral irrigator called a Waterpik!
I had braces until last year, and now I just wear a retainer.
Brushing your teeth is difficult when you have braces, but using a Waterpik makes brushing easier and seems to make my teeth whiter.
There are also many replacement tips, so it's great that I can use them depending on the type I want!
I highly recommend Waterpik to those of you who, like me, have braces and find flossing difficult.
The only downside is that it might hurt a little when you first use it.
