Hi, guys,

It's been 1.5 years since I had my dental braces.  My ortho is trying
to correct my bite now using elastic rubber bands.

I have bummer (a type of rubber band) on the left and the right, and
debbie (another type of rubber band) in the front.

I was asked to ware one bummer on the left, one bummer on the right
and one debbie in the front.

I am just wondering if I can hook up 2 bummers on the left, 2 bummers
on the right and 2 bummers in front.

The reason why I wanna do this is because it doesn't feel tight enough
with only 1 rubber band at each of the 3 spots.  However, I don't
wanna get into trouble by doing this.

So, is it safe to wear 2 instead of 1 at each spot?  Thanks.
