How To Use Baking Soda And Peroxide To Whiten Fake Teeth

Cosmetic dentistry includes all kinds of dental procedures for replacing and repairing missing or broken teeth. It also includes teeth whitening, which works quite well on natural teeth, but not so much on dental implants. However, there is something you can do to whiten dentures using baking soda and peroxide. In addition to whitening your dentures this way at home, you are saving the cost of replacing the dentures for whiter ones, or having your dentist try a professional treatment often reserved for real teeth.

Step 1: Brush and Clean Your Dentures As You Normally Would 

Most denture wearers brush and clean their dentures before going to bed at night. Then they let them soak in a cup, often with a mint tablet to freshen them up for the morning. You can skip the refreshening mint tablet part here, and just brush and clean your dentures as you normally would. Leave them out of the soaking cup for the next step.

Step 2: Empty Your Denture Cup and Fill It Halfway with Peroxide

Peroxide is safe enough for oral use, which is why this method is much better than using actual bleach. (Using actual bleach on your dentures may yield results, but it also leaves behind a corrosive and deadly poison that can leach out of your dentures and into your body.) You can find the bottles of peroxide in any first aid section of a drug or grocery store. Taking into account the chemical reaction which occurs when you combine peroxide and baking soda, be sure to fill your denture cup only about halfway with undiluted hydrogen peroxide. 

Step 3: Wet Your Dentures and Then Sink Them into the Baking Soda

Wetting your dentures before coating them with baking soda ensures that there will be enough baking soda covering the total surface area of your dentures. You want the fake teeth portion of the dentures to look like you bit into a cake of baking soda or you coated them with a thick layer of flour; the baking soda layer on your fake teeth should be that obvious. The easiest way to do this is to pour the baking soda into a small mixing bowl or cereal bowl and then push the wet dentures into the baking soda.

Step 4: Drop the Baking Soda-Coated Dentures into the Peroxide Cup

Drop the baking soda-coated dentures into the peroxide-filled denture cup. (You may want to do this final step entirely over the sink or in the sink, with the peroxide-filled cup perched just over the top of the open sink drain. Any overflow of solution that occurs will then go right down the drain and there will be little mess to clean up.) Immediately, a chemical reaction will occur and the combined baking soda and peroxide will bubble up like an effervescent tablet. Close the denture cup and leave your dentures like this all night. If they are not as white as you would like them by morning, repeat this process nightly until they are the shade of white you want.
