A stained smile can make patients feel more self-conscious. Coffee, tea, wine and other colored drinks and food stain your teeth over time. Whitening procedure removes those stains and brightens the enamel of the tooth. There are two types of whitening systems: in-office procedure and take-home procedure.
In office procedure, which averages about 90 minutes, will give you a more immediate result. Take home treatment alternatives involve wearing trays and applying whitening solution daily for 30-45 mins at a time for about 4-5 consecutive days to achieve the same result as one hour in office procedure.
