What’s the best flossing technique?

For me, it’s best to do it in front of a mirror so you see what you’re flossing and see if you’re applying a proper amount of pressure

I use a waterpik even though my dentist advised against it. I prefer it when something is caught because it feels like floss can push it in more. I waterpik at night and traditional floss in the morning to make sure nothing is missed.
