Do whitening toothpastes work?

So far I have been extremely impressed by your service. I trust you with a question which I know many people share: Are whitening toothpastes detrimental to the longevity of one's teeth?


Why am I itchy after the condom broke?

I've just had my first condom break ever. I'm on the pill, so I'm not worried about pregnancy, but a couple of days afterwards I had yeast infection-like symptoms — no unusual discharge, just itching. If I pick up some over-the-counter yeast infection medication and the symptoms go away, would I be safe to assume that was the problem? Or should I definitely go in for an STI check?
