Can you whiten dentures?

Yes, but it's important to note that whitening false teeth with stains is not the same as whitening dentures without stains. This is because a denture's natural shade cannot be changed.

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

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

Dentures should be cleaned regularly to not only prevent gum disease and bacterial infections but also stop them from starting to yellow or stain. That's because dentures are made from acrylic and can become stained by factors like poor hygiene and irregular cleaning.

How to whiten dentures at home?

If your dentures stain over time, you can try several home remedies featuring everyday household ingredients. Try out these tips that will help you remove stains and whiten dentures.


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

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 so that they last a long time.

Dentures can be cleaned with easy-to-find products

Denture cleaning solutions are available at your neighbourhood pharmacy or the local dental clinic. You can also buy them online, but check with your dentist first to make sure you are buying the right cleaning solution for your dentures.

To use a denture solution, read the instructions first. Most recommend soaking your dentures in the solution for a set period of time before brushing them.

Always rinse your dentures with water after cleaning them before you put them back in your mouth.

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 them with a soft 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 sanitiser 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 sanitise 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 grocery shop or supermarket, and most of us probably have some in the kitchen right now.

Baking soda is also great for eliminating odours. 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. You should never use the following things to whiten dentures or clean your dentures.


Although household bleach is great for cleaning clothes and surfaces, it should never be used on dentures.

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 cause them to fit poorly.

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