How to remove food from a cavity hole? This is bothering me to know end and I don't go to the dentist till next week. Pls no rude answers?

I have a cavity on my upper back tooth. It builds up food and of course it smells. I've researched to know end on how to remove food from there. I know my fam is tired of the loud clicking noise I make w/ my tongue trying to suck food out of the cavity hole. I brush twice or sometimes 3x a day, I floss, use plackers, and the little bristle things that look like tooth picks with bristles and they work only a little. Floss and the plackers don't help and the tooth bristles work until they start to bend. I've tried rinsing with mouthwash and peroixide..nothing helps. I go to the dentist to get it looked at on July 11th. They aren't gonna actually do the procedure then. Someone has to know od some way I can remove this food from this hole in the meantime.
