Just back from dental, doctor asked to get whitening toothpaste because that's always stains on my gigi.
Got sidetracked by other question, i forgot to ask about the details of the whitening toothpaste.
What kind of whitening toothpaste the doctor mean? The common toothpaste I bought from the stall did mentioned whitening function too, i guess that's not enough? What kind of specific toothpaste should i get and where can i buy them?

not really 
My dental appointment is next week, i can check with my dentist if they complain again XD
