Dentures are an important investment. But how do you whiten dentures and bring back your dazzling smile?

Maintaining dentures is more than just keeping them bright and white — hygiene maintenance is also equally important.

In this post, we cover expert and practical advice, including both home remedies and professional care you should take, along with tips on what to avoid when whitening dentures.

Can dentures be whitened?

Yes, but it is important to note that the process of whitening false teeth due to stains is not the same as whitening dentures without any stains. This is because the denture’s natural shade cannot be changed.

Basically, if you have been wondering how to make new dentures whiter after they've been constructed, unfortunately, there is no way to brighten the base color of constructed dentures (or bonding, for that matter).

Keep your dentures looking bright and white.

However, stained dentures are a different story. Denture whitening eliminates stains that have accumulated over time and restores the original false tooth color. If you leave the surface stains uncleaned for a long time, it will be harder to get rid of the stains long-term.

Irregular and poor denture hygiene may lead to bacterial infection and other related diseases. Your false teeth are made from acrylic, and these factors result in dentures yellowing or staining.

What are some home remedies to whiten dentures?

If your dentures stain over time, you can try several home remedies featuring everyday household ingredients. Try out these tips that will help you whiten dentures and maintain their stain-free state.


Consuming dark-colored foods and beverages can easily stain your dentures, including:

  • Coffee or tea
  • Red wine
  • Berries

Removing and rinsing your dentures after eating or drinking these foods is the best way to get ahead of the game and keep dentures white. Preventive maintenance is critical for keeping your dentures clean and lasting a long time.

Denture solution

Denture cleaning solutions are available at your neighborhood pharmacy or the local dental clinic. Soak the dentures in the solution and brush them in the morning. Rinse with water.

Hydrogen peroxide

Hydrogen peroxide is known for its bleaching effects and is a common ingredient in many teeth whitening products. It can effectively remove the stains that build up on the denture’s surface.

You can whiten dentures with hydrogen peroxide by taking them out, coating the dentures with hydrogen peroxide, and gently brushing with a toothbrush. Next, rinse the dentures thoroughly to remove any product.

Some studies suggest that hydrogen peroxide may have antimicrobial properties, but more research is needed.

White vinegar

Cleaning dentures with white vinegar is a great option because it is a natural sanitizer that will destroy any bacteria. Soak them overnight in vinegar. The next morning, use a toothbrush and brush the dentures — most surface stains will lift easily.


Dentures may be easily cleaned by dipping a wet toothbrush in salt and scrubbing the surfaces. Or, to disinfect and sanitize dentures, submerge them in a saltwater solution overnight.


Lemon juice is naturally acidic and contains citric acid, which is a known bleaching agent. Although it's not good for natural teeth, soaking dentures in a solution of lemon juice and water for 30 minutes can lift some of those surface stains. Rinse with cool water after soaking.

Baking soda

Both dentures and natural teeth can benefit from using baking soda. It can whiten teeth and dentures. It is also easily available in your local drug store or grocery store, and most of us probably have some in the kitchen right now!

Baking soda can eliminate odors as well. Use a toothbrush and a solution of baking soda and water to whiten the dentures.

What to avoid when whitening dentures

Certain products may prove hazardous to your health and even damage your dentures. We've put together a list of products you should never use to whiten dentures or clean your dentures.


Although household bleach is great for cleaning clothes and surfaces, it should never be used on dentures. You wouldn't use household bleach on your teeth, so don't use it on your dentures either.

Using bleach to whiten teeth is not only harmful if swallowed, but it will also destroy your dentures if you use it on them. The bleach will leave a stain on the pink part of your dentures that cannot be removed.

Boiling water

Never put your dentures in hot water to clean them. Cleaning tabs, brushing, or even saltwater are all better options. Keep your dentures in cold or room-temperature water because boiling water can warp your dentures and create a poor fit.


Now that you know how to whiten false teeth safely, try out the tips mentioned above to remove surface stains from dentures and avoid harmful products.

If nothing you try appears to give you white dentures, consult your dentist or a dental lab. They may be able to suggest additional options that are more suitable for your particular situation.

If you're unsure about a fake teeth whitening method you've heard about, consult an expert first.


Can you whiten fake teeth with household bleach?

You should never use household bleach to clean your dentures because it can be harmful to your health and your dentures. You can, however, use household products like baking soda or salt.

How do I whiten dentures fast?

Although you can always give your dentures a quick rinse and scrub, most solutions require an overnight soak. You want your dentures to last, so take the time to care for them.
