Great!: Front teeth, being thinner and flatter in shape, are easier to whiten than the back teeth. So that is a great news.... Now it is time to see a dentist and find out why the front teeth are yellower. Soon you will know the best way to have all evenly white teeth. Teeth in 20's and 30's are also easier to whiten than teeth later in life, but if whitening is not indicated, veneers may be an option.
