A trip to the dentist for a whitening session could be costly and painful, for some; let along the coffee/soda deprivation for at least 4 days. Here are do it yourself recipes that would help get similar results at the comfort of your bathroom.
Dip a cotton bud in lemon juice then in baking soda powder; apply the mélange onto your teeth and leave it on for about a minute.
Brush your teeth to remove the paste…you will see immediate results in the first couple of days.
Other recipes include hydrogen peroxide mixed with baking soda, then brush for 2-3 minutes. You may start to see results in a couple of weeks.
