Help please i have a sliver of doritos chips stuck in my gums. how do i get it out?

Floss + Floss: Hold 2 pieces of floss together (thus double up), and gently place in between the teeth. Make sure the floss goes in the space between the tooth and the gum. Gently pull them (2 pieces) out to see if they catch the snack piece. Repeat. If the piece is in not between the teeth, gently "sweep" the area with a very thin tooth pick to lift up the piece. Visit a dentist if you are unable to get it out.

In addition to : Dr. Yamaguchi's very comprehensive answer, you might try interdental picks (soft picks or go-betweeners by sunstar) or a waterpik both readily available and good to use on a daily basis as we'll. Hope this helps.
