Dentures play a big role in restoring confidence, comfort, and function when natural teeth are lost. In Australia, research shows that around one in six people over the age of 15 has no natural teeth and relies on some form of dentur.
Despite how common they are, many wearers struggle with cleaning and caring for them.
Good hygiene isn’t only about keeping your dentures looking white and stain-free. It helps prevent infections, improves comfort, and extends the life of the appliance.
Surveys suggest that up to 89% of denture wearers are not cleaning them properly, which can cause odour, irritation, and avoidable dental visits
The good news is that caring for dentures is simple once you know what to do. This guide explains step by step how to clean, store, and maintain dentures, so they remain fresh and comfortable every day.
Why Cleaning Dentures Naturally Is Important
- Oral health protection: Food debris and plaque can accumulate on dentures just like on natural teeth. If not cleaned away, this can lead to infections such as denture-related stomatitis, a fungal infection under the denture that causes sore, red gums.
- Fresh breath and stain control: Residue from food, coffee, tea, and smoking can quickly stain dentures. Bacteria trapped in the surface can also cause persistent bad breath.
- Longer lifespan for your dentures: Dentures are a significant investment. Proper cleaning prevents scratches, warping, and plaque build-up that might shorten their life.
- Confidence and comfort: Clean dentures fit better and feel more natural. Wearers often say that fresh dentures give them more confidence in social and professional settings.
Good care habits not only protect the denture itself but also help safeguard your overall oral health.
How Often Should You Clean Your Dentures
- Daily brushing: Dentures should be brushed twice a day – once in the morning and once before bed. This removes plaque and helps keep them fresh.
- Rinse after meals: A quick rinse under running water after eating washes away food particles before they have a chance to stick.
- Night-time removal: Dentists recommend removing dentures every night. This gives the gums a rest and reduces the risk of fungal infections.
- Soaking routine: Daily or nightly soaking in a cleaning solution provides an extra layer of hygiene by killing bacteria and loosening stains.
A consistent cleaning schedule keeps dentures in top condition and makes wearing them more comfortable day after day.
Supplies You Need for Cleaning Dentures
Having the right tools makes the job easier and safer. Here’s what every denture wearer should keep on hand:
- Denture brush or soft toothbrush: Special denture brushes are designed to clean all surfaces. A soft toothbrush is fine if a denture brush isn’t available.
- Mild cleanser: Regular toothpaste is too abrasive and can scratch the denture material and acrylic surface. Use mild dish soap, hand soap, or denture cleanser.
- Denture cleaning solution: Effervescent tablets or liquid soaks disinfect and freshen dentures. Always follow the product’s instructions.
- Storage container: A clean container with a lid is ideal for soaking dentures overnight. Cleaning over a towel or bowl of water can prevent breakage if they’re dropped.
- Optional extras: Adhesive remover wipes, a spare toothbrush for denture use only, and a soft cloth for wiping can be helpful additions.
Having these supplies ready means cleaning becomes part of a quick, stress-free routine.
Step-by-Step: How to Clean Dentures Properly
Step 1: Preparation and removal
Start by placing a folded towel in the sink or filling the basin with a little water. This cushions the denture if it slips. With clean hands, remove the denture carefully and rinse it under lukewarm running water to dislodge food particles.
Step 2: Brushing the denture
Using a denture brush or soft bristled toothbrush, gently brush all surfaces. Pay attention to the gum-coloured base and the grooves where food can lodge. Use mild soap or denture paste. Do not use regular toothpaste as it is abrasive and may leave scratches that trap bacteria.
Step 3: Cleaning your mouth
While dentures are out, brush your gums, tongue, and the roof of your mouth with a soft toothbrush. If you have natural teeth, continue your usual brushing and flossing routine. Maintaining good oral hygiene is just as important as keeping the denture clean.
Step 4: Soaking the denture
Place the denture in a clean container filled with lukewarm water and add a denture-cleaning tablet or solution. Soak them either overnight or for the time recommended on the packet. Soaking loosens stubborn stains and helps kill bacteria.
Step 5: Rinse and reinsert
Before putting dentures back into your mouth, rinse them thoroughly with cool water to wash away any cleanser residue. Hot water should never be used as it can cause warping.
Denture Cleaning Do’s and Don’ts
Do
- Brush and soak every day to keep dentures free of bacteria and dental plaque buildup.
- Hold dentures gently but securely to avoid dropping them.
- Keep dentures moist when not in use by storing them in water or solution.
- Clean your gums, cheeks, tongue, and any natural teeth daily.
Don’t
- Use boiling or very hot water. It can change the denture’s shape.
- Use abrasive products such as regular toothpaste, bleach, or rough powders. These can damage the surface.
- Scrape dentures with sharp tools to remove residue.
- Ignore pain or sores caused by dentures. Discomfort may mean an adjustment or replacement is needed.
A simple checklist of do’s and don’ts gives denture wearers a reliable guide for everyday care.
Caring for Different Types of Dentures
Full Dentures
Standard cleaning steps apply, with extra care on the areas that sit against gums.
Partial Dentures
These often have metal clasps that need gentle cleaning. Avoid harsh cleaners or bleach, which can corrode metal. Remember to thoroughly clean remaining natural teeth, as plaque can transfer between teeth and the denture.
Implant-Supported Dentures
Remove the denture for cleaning, but also clean around the implant attachments with a soft brush or interdental cleaner.
Dentures With Soft Liners
These linings can be sensitive to harsh chemicals. Stick to gentle soap and water or follow your dentist’s instructions.
Flexible (Nylon) Dentures
Usually only require brushing with mild soap and lukewarm water. Check with your dentist for suitable products, as not all cleansers are safe for nylon materials.
Each type of denture needs slightly different care. Following the right method will keep them looking good and fitting comfortably.
Common Denture Cleaning Products and Methods
There are different approaches to cleaning dentures, each with its benefits and drawbacks.
| Method | Pros | Cons / Cautions |
|---|---|---|
| Brushing with soap/water | Cheap, easy, removes food and plaque directly. | Doesn’t kill all bacteria, needs soaking support. |
| Tablet soak (effervescent) | Kills odour-causing bacteria, simple to use, good for overnight. | Won’t remove heavy plaque, follow instructions carefully. |
| Ultrasonic cleaner device | Very effective at cleaning small crevices, gentle on denture. | Cost of device, still requires occasional brushing. |
| Vinegar soak (DIY) | Affordable, can dissolve tartar deposits. | Strong taste/odour, can damage metal clasps, should be used rarely. |
| Dilute bleach soak | Disinfects stubborn stains and fungus on plastic dentures. | Unsafe for dentures with metal parts, risk of discolouration, only under professional guidance. |
For most people, a combination of brushing and a daily soak in tablets is enough. More intensive methods like ultrasonic cleaning or vinegar are better kept for occasional use.

Storing and Maintaining Dentures Long-Term
Dentures need just as much care when they’re not in your mouth. Proper storage and maintenance help them last longer and stay comfortable.
- Overnight storage: Dentures should be kept moist to prevent them from drying out and warping. The easiest way is to store them in a container filled with clean water or a denture-soaking solution.
- Avoiding damage: Wrapping dentures in tissues or leaving them on the bedside table can lead to accidents, such as being stepped on or even chewed by pets. Always use a dedicated container with a lid.
- Regular dental check-ups: Even with excellent home care, professional checks are important. Dentists can clean off tartar, polish away stains, and adjust the fit if your gums or jawbone have changed. Relining or replacing may be needed if dentures become loose.
- Replacement timeframe: On average, dentures last between 5 and 7 years before needing replacement. Signs they may need replacing include cracks, worn teeth, or frequent sore spots.
- Emergency fixes: If a denture breaks, don’t attempt to glue it with household products as these are not food-safe and can damage the material. Keep any broken pieces and take them to your dentist for repair.
With a little care in how they’re stored, dentures will remain safe, fresh, and ready to wear each day.
Frequently Asked Questions
Can I Use Regular Toothpaste on Dentures?
No. Regular toothpaste contains abrasive particles that can scratch dentures. Those scratches trap bacteria and make odour worse. Use mild soap, dishwashing liquid, or denture paste instead.
Is It Safe to Sleep With Dentures In?
It is best to remove dentures at night. Wearing them 24/7 increases the risk of fungal infections and speeds up bone loss in the jaw. If you do wear them occasionally at night, ensure they are thoroughly cleaned.
How Do I Remove Stubborn Stains or Tartar?
Daily brushing and soaking usually prevent stains. For heavy staining, try a vinegar soak (half water, half vinegar) for a few hours, but not if your denture has metal clasps. Persistent stains should be cleaned by a dentist or dental prosthetist.
My Dentures Smell. How Do I Keep Them Fresh?
Persistent odour usually means plaque is still present. Make sure you brush every surface, including the underside, and soak daily in a tablet solution. Cleaning your tongue and gums reduces overall bacteria in the mouth.
How Often Should Dentures Be Replaced?
Most dentures need replacing every 5–7 years. If yours are loose, damaged, or no longer comfortable even after adjustments, it’s time to see your dentist.
Can I Whiten Denture Teeth?
Teeth whitening products don’t work on dentures. The material won’t respond the way natural teeth do. Instead, keep up with good cleaning habits and ask your dentist about professional polishing or replacement if appearance is a concern.
What’s the best way to remove denture adhesive?
Adhesive can be loosened by rinsing your mouth with warm water and gently massaging your gums with a soft cloth or brush. For dentures, a denture brush with soap works well. Special adhesive remover wipes are also available.
