Is it necessary to brush teeth? Check out the best possible answer.

Brushing our teeth boosts our sperm count. Researchers at the Bikur Cholim Hospital in Jerusalem found that half of the men they studied with a low or terminal sperm count also suffered from periodontal gum disease. "Brushing your teeth may not sound sexy, but this study shows its importance to male fertility," says Nigel Carter of the British Dental Foundation. Previous studies have shown a link between gum disease and increased rate of heart disease, diabetes and strokes-so if you want to look after your swimmers, brush up on your dental regime.
