Rinse with lemon juice will strengthen the teeth? This is something new for me.

I never know that lemon will have such effect. The tea one I also never hear before.
I think another aspect that cause bad breath is internal heatiness. Go and see a chinese doctor loh. They will prescribe concotions that rid your inner heatiness. Those that will revert your inner heat to equilibrum.
My tooth brush last me usually for 3 months. I buy the soft type which is better for my teeth. Dont want to hurt them unnecesary.
.... Soooo.. oral sex will not lead to bad breath...
