Do people who maintain the device have trouble removing the bond?

After the orthodontic treatment is finished, a retainer is attached inside this area.

I find this to come off very easily, how about others?

My friend says he has never failed once.

I always seem to fail at least once a year.

If I fall, I want to go to the nearby dentist, but they charge 30,000 to 50,000 won per visit, so it's burdensome.

I have to go to the orthodontic dentist I used to visit, but it's so bothersome.
