Today is the week end in egypt ( friday). I looked to myself at the mirror anf I find myself having a yellow teeth, I searched for something to do I find a recipe to white the teeth using a paste of hydrogen peroxide and bicarbonate of sodium ( soda) you make the paste and it will effervescence then put it on the bruth and wash the teeth. I think this work by irritate the yellowish layer on the teeth. I am also thinking that the yellow teeth can result from the weather and some anerobice bacteria ( may be). or due to Tetracycline which is taken for the acne ( I doubt)
My Thoughts about Egypt and the Egyptian life.
