An Alternative Remedy for Yellowish Teeth

My teeth were looking yellowish. When my wedding got fixed, I was looking for ways to get rid of it. So I did thorough research on it. When I did an online search, I came across a dental clinic that does the whitening procedure. So I took the details and approached them. When I told the dentist in the clinic about this situation, he examined my teeth and fixed a day to do the whitening. When the entire procedure was over, I was surprised to see my teeth, which boosted my confidence. Everybody was stunned to see me on my wedding day as many were saying I was looking pretty with a beautiful smile on my face. Does anybody know the standard cost of the whitening procedure?
