Clean dentures every day to prevent stains, odor, and buildup that damages the fit
Dentures need cleaning every single day, just like natural teeth. Food particles, plaque, and bacteria collect on the surface and inside the base. If you skip cleaning, dentures develop permanent stains, smell bad, and the material can warp or crack. The good news: daily cleaning takes five minutes and uses supplies you can find at any drugstore.
There are two types of cleaning you need to do: daily brushing and soaking. Daily brushing removes food and loose plaque. Soaking overnight (or for several hours) kills bacteria and loosens stubborn buildup. Most people do both every day — brush in the morning and evening, soak overnight.
The supplies are inexpensive and last months. You need a soft-bristled denture brush or regular soft toothbrush, denture cleaner (powder or tablet), and a denture cup or small container. Do not use regular toothpaste, bleach, or hot water — these damage dentures.
Key Takeaways
- Brush dentures over a sink filled with water or a towel so they do not break if you drop them.
- Use only denture cleaner tablets or powder, never regular toothpaste or bleach, because they scratch or discolor the material.
- Soak dentures overnight in denture cleaner solution to kill bacteria and loosen stains that brushing alone cannot remove.
- Rinse dentures thoroughly with cool water before putting them back in your mouth after soaking.
- Clean your mouth and any remaining natural teeth before reinserting dentures each morning.
Daily brushing: the right way to do it
Fill your bathroom sink with cool water or lay a folded towel on the counter. This cushions dentures if you accidentally drop them — dentures break easily on hard surfaces. Hold the dentures firmly but gently over the water or towel.
Wet the dentures with cool water. Use a soft-bristled denture brush or a regular soft toothbrush. Brush all surfaces: the outside (the part people see), the inside (the part that sits against your gums), and the chewing surface. Pay extra attention to the grooves and crevices where food hides. Brush gently — you are not scrubbing a pot. Denture material is softer than natural tooth enamel and scratches easily.
Rinse thoroughly under cool running water until no soap or debris remains. If you see food particles still stuck, use your fingernail or a soft cloth to gently wipe them away. Do not use a toothpick or metal tool — these gouge the surface.
Soaking: how to remove stains and kill bacteria
Soaking is the second half of daily cleaning. It removes stains that brushing misses and kills bacteria that cause odor. You soak dentures overnight (at least 6 to 8 hours) or during the day if you wear them only part-time.
Fill a denture cup or small container with cool water. Add one denture cleaner tablet or follow the powder instructions on the package. Drop your dentures in and let them sit. Do not use hot water — heat warps dentures. Do not use regular mouthwash, vinegar, or bleach solutions, even diluted. These damage the material or cause discoloration.
Common denture cleaners include Polident, Efferdent, and store-brand equivalents. All work the same way: the tablet or powder dissolves and creates a cleaning solution. A box of tablets costs $5 to $10 and lasts about a month. Powder is usually cheaper per use.
After soaking, remove the dentures and rinse them thoroughly under cool water. Brush them again lightly to remove any remaining debris. This double cleaning — soak then brush — is more effective than either alone.
What to do about stubborn stains and buildup
If dentures develop brown or yellow stains that soaking does not remove, the stain may be permanent discoloration of the material itself, or it may be buildup that needs stronger treatment. Try soaking for a longer period — 12 to 24 hours — with a fresh tablet or powder.
If stains persist, your dentist or denturist can clean dentures professionally using an ultrasonic cleaner and specialized solutions. This usually costs $20 to $50 and removes buildup that home cleaning cannot. Professional cleaning also lets them check the fit and condition of the dentures.
Do not try to bleach dentures or use abrasive scrubbing pads. These permanently damage the surface and can make stains worse. If dentures are cracked, have a rough spot, or feel loose, see your dentist before the damage spreads.
Caring for your mouth while dentures are out
While dentures soak or while you are cleaning them, clean your mouth. If you have any natural teeth remaining, brush and floss them. Rinse your mouth with cool water or mouthwash. Gently brush your gums, the roof of your mouth, and your tongue with a soft toothbrush — this removes bacteria and keeps tissues healthy.
Leaving dentures out for several hours a day (usually overnight) lets your gums rest and reduces irritation. This is one reason soaking overnight is better than just brushing: your mouth gets a break from wearing dentures, and your gums stay healthier.
Storage and handling between cleanings
Store dentures in a denture cup filled with cool water or denture solution when you are not wearing them. Do not wrap them in tissue or leave them dry on a shelf — dentures can warp if they dry out, and tissue makes them straightforward to throw away by accident.
Keep the denture cup in a safe place away from pets and children. Dentures are fragile and can be a choking hazard. If you travel, use a small denture case with a tight lid to keep dentures moist and protected.
Handle dentures carefully. Rinse them before putting them in your mouth. If you drop them, rinse them again before wearing them — the floor is not clean. If dentures crack, chip, or feel loose, contact your dentist. Wearing damaged dentures can hurt your gums and make eating difficult.
Common mistakes that damage dentures
Using hot water is the most common mistake. Hot water warps the plastic base and can loosen the teeth. Always use cool or lukewarm water. If you accidentally use hot water, let the dentures cool completely before wearing them.
Using regular toothpaste scratches dentures and leaves a film that traps bacteria. Denture cleaner is designed for the material and works better. Bleach and vinegar solutions discolor dentures and weaken the material over time.
Skipping soaking and only brushing leaves bacteria and stains that build up. Soaking is not optional — it is the only way to kill the bacteria that cause odor and infection. Brushing alone cleans the surface but does not reach inside the pores of the material.
Leaving dentures dry overnight damages them. Denture material needs moisture to stay flexible. Dry dentures crack, warp, and become uncomfortable to wear.
Frequently Asked Questions
Can I use regular toothpaste on dentures?
No. Regular toothpaste is too abrasive and scratches dentures. It also leaves a residue that traps bacteria and causes odor. Use only denture cleaner tablets or powder made for dentures.
How often should I soak dentures?
Every day, ideally overnight for at least 6 to 8 hours. If you wear dentures only during the day, soak them while you sleep. If you wear them 24 hours a day, soak them for at least a few hours each day — many people soak them while they shower or eat meals.
What if dentures smell bad even after cleaning?
Odor usually means bacteria are still present. Make sure you are soaking every day with a fresh tablet or powder, and brush before soaking. If odor continues, try soaking for 12 to 24 hours with a new tablet. If the smell persists, see your dentist — the dentures may need professional cleaning or there may be a fit problem allowing bacteria to grow underneath.
Can I sleep without dentures in my mouth?
Yes, and many dentists recommend it. Sleeping without dentures lets your gums rest and reduces irritation. Store them in a denture cup filled with cool water or denture solution overnight. Your mouth will be healthier if dentures are out for at least a few hours each day.
What should I do if dentures crack or chip?
Stop wearing them and contact your dentist or denturist right away. Wearing cracked dentures can cut your gums and cause infection. Small cracks can sometimes be repaired, but large ones may require a new denture. Do not try to glue dentures yourself — the repair will not hold and may make the damage worse.
