Around here, a retired toothbrush has a long and illustrious life. Great for parts cleaning, reaching into awkward crevices in the washing machine, etc. etc. When the end comes there are no bristles left.
BTW, you're not brushing your teeth so much as you're cleaning/stimulating your gums. That's where there are bona-fide health risks and benefits.

I think the many different smells of all the plants mask our scent. On the flip side when we walk the 20 paces to the neighbors front lawn they swarm. Oh, and standing water isn't the cause of our mosquitoes, moist soil is.
