How much does teeth whitening usually cost?

i'm thinking about getting it done i was going to try the white strips do they work just as good or should i just go to the dentist ?

White strips work, but they cause sensitivity to your gums. Hydrogen Peroxide works great! You can buy this at Walmart. All you do is: first take regular mouthwash like listerine then brush your teeth-Crest Vivid White 3D best toothpast ever for whitening teeth it removes to 80% stains in 14 days! It only cost $3 it works. Then take Peroxide and swish it around your mouth or take a cotton ball and dab peroxide on it and place on the tooth! It works. A lot of people do it to whitening their smile for weddings! Hope this worked!
