Can Dentures Be Made Whiter?

While there’s no method available to change the actual color of the denture material, you can whiten your dentures by getting rid of surface stains that have built up over time [1]. If your dentures are stained, here are some valuable tips on how to clean dentures properly to make them look white again.


Clean Regularly

Your dentures will fit better and last longer if you take care of them. Here are some tips to ensure your dentures stay in excellent shape.

  • Always remove and rinse your dentures after drinking and eating to get rid of food debris and other particles.
  • Clean your mouth each time you remove your dentures. Brush your real teeth and gauze with a soft or regular toothbrush, and then clean your tongue, roof of mouth, and inside of your cheeks. If you use denture adhesive, remove all of its remains from your gums. 
  • Rinse your dentures thoroughly before putting them back in your mouth, especially if you’re using a soaking solution, as it may contain toxic chemicals that cause burns, pain, or vomiting if swallowed.
  • Handle your dentures with care, and be sure not to damage or bend the clasps or the plastic when cleaning. Also, avoid using hot water for rinsing or soaking as it can damage dentures.


Use Appropriate Products

If your dentures have stained over time, there are several safe products you can use to whiten them at home.

  • Denture soaking solution: To maintain their shape and keep them clean, place your full or partial dentures in a gentle denture-soaking solution and give them an overnight soak. Follow the manufacturer’s directions on using soaking and cleaning solutions.
  • Non-abrasive toothpaste: Brush your dentures every day with a non-abrasive toothpaste and soft or regular toothbrush to remove plaque, food particles, and other debris. 
  • Mouthwash: Soak dentures in equal parts water and equal parts mouthwash for at least 30 minutes. Be sure to rinse them thoroughly before wearing them.
  • Dental floss: Use dental floss to clean tight spaces in your full or partial dentures—clean them like you would natural teeth.


Professional Cleaning

If your partial or full dentures are heavily stained, you can consult your dentist about having them professionally cleaned. They can be polished to remove stains and evaluated to ensure the best fit. Many dental professionals recommend getting your denture teeth cleaned once or twice per year.


How Do You Clean Badly Stained Dentures?

You can clean badly stained dentures with a denture cleanser and wet denture toothbrush or soft-bristled toothbrush. Give your denture teeth an overnight soak with a commercial cleansing tablet solution or a homemade denture stain remover such as salt, denture bleach, and vinegar [2].


How to Whiten Dentures From Smoking


Whitening solutions for dentures stained with smoking


If your new dentures are stained from smoking, try these whitening solutions:

Regular brushing with a soft toothbrush can help remove nicotine stains from dentures. 

Hydrogen peroxide contains an effective cleansing agent that whitens dentures with cigarette stains. Gently scrub your dentures with a soft toothbrush that’s been dipped in hydrogen peroxide and rinse them thoroughly before putting them back in.

Denture bleach is gentler than household bleach. Add one teaspoon of dental bleach to a cup of water. Soak your dentures for around 15 minutes and then rinse them well.

Baking soda deodorizes and cleans dentures. Apply it directly to your dentures with some water and brush gently with a soft toothbrush. Alternatively, you can rub the cleaning product gently around the false teeth by hand. Make sure to rinse the dentures thoroughly.

A water and white vinegar solution is one of the simplest home remedies for removing cigarette stains from your dentures. Simply soak your dentures overnight in this solution and rinse them off in the morning.

Salt can whiten your nicotine-stained dentures as well. Take out your dentures and dab your soft toothbrush with some salt, then gently brush the dentures. Alternatively, you can mix a tablespoon of salt with one glass of water. Give your dentures an overnight soak in this solution. The next morning, gently clean them with a toothbrush and rinse them thoroughly.

Mouthwash can eliminate bacteria accumulating in the mouth. Mix half a mug of mouthwash and half a mug of water and then soak your dentures in this solution. Let them soak for 30 minutes and then rinse them properly with cold running water. 

Lemon juice contains bleach-like properties, making it a good cleanser for dentures. Juice a lemon into one cup of water and soak your false teeth in this cleaning solution for around 30 minutes. Rinse the dentures and then put them back in.

Denture cleaning tablets can help remove stains caused by smoking. The fizzing action of the tablets will gently remove stains from dentures and kill the bacteria from loose food particles. Make sure to follow the manufacturer’s instructions for optimal results.


How to Whiten Dentures Fast

If your dentures’ surface has been stained, you can have them cleaned by a dentist. However, you might not always have the cash and time. If so, the following home remedies can help whiten your dentures fast and keep them stain-free:

  • Mint, chamomile, oak bark: A combination of these herbs will cleanse your dentures, disinfect them, keep bad breath at bay and, of course, help whiten them.
  • Tooth powder, lemon, and vinegar: Mix one tablespoon of vinegar with one tablespoon of lemon juice. A reaction may occur, which is perfectly normal. Mix the solution with tooth powder to make a paste, apply a thin layer of this paste on your dentures, and leave it for 90 minutes. Then thoroughly rinse the dentures with cold water and wipe the dentures dry with a clean cloth.
  • Ultrasonics: Soaking your dentures in an ultrasonic cleaner is one of the best ways to make your dentures white. This denture cleaning solution improves the cleaning done with a toothbrush as it removes microscopic food bits from areas where even the softest brush can’t reach.


DIY Denture Whitening

Regular cleaning of your dentures is not only important for maintaining good oral health but also increasing the shelf life of your new dentures.

Simply fill a cup up with white vinegar and soak dentures in it overnight. The following morning, take out the dentures and brush them with a toothbrush to remove stains with ease.


How to Whiten Dentures With Baking Soda

Brush your dentures gently with this denture paste, making sure to reach all the crevices. Once you’re done, rinse your dentures with running water.

Baking soda can also get rid of odors that have developed on your dentures. Simply add the baking soda, along with a few drops of water, to create a paste. Gently apply this denture paste with a toothbrush, leave it for at least 15 minutes, then rinse with running water.
