Crikey, 20 is very young to lose toothipegs. I was taught to take care of my teeth and have spent a fortune on the buggers, even the sodding extraction cost £100, but after the age of 40 they began to give out and gums began bleeding. I reckon I would have lost them all by now but for those little Tepo inter-dental brushes and my mad, sadistic, scary Greek dental hygienist (who I am seeing very soon to shed another £150 for 20 mins of agony).
