In brief
Good denture care has four parts: rinse after eating, brush the denture daily with a denture brush and non-abrasive denture cleanser (not regular toothpaste), remove it at night and soak it in water or a denture solution so it never dries out, and clean your gums, tongue and any remaining teeth just as carefully as the denture itself. Done daily, this prevents the stains, odour and gum infections that neglected dentures reliably cause.
Key takeaways
- Brush the denture daily with a denture brush and denture cleanser — never regular toothpaste, which is too abrasive.
- Remove dentures at night and keep them moist; drying warps the acrylic.
- Clean gums, tongue and remaining teeth daily — tissue care matters as much as denture care.
- Fill the sink with water or lay a towel down when cleaning; dropped dentures break.
To clean dentures, rinse them after meals, brush them once a day with a soft denture brush and a non-abrasive denture cleanser or mild soap, and soak them overnight in water or a denture solution so they never dry out. Just as important, clean your gums, tongue and any remaining natural teeth every day, and see your dentist regularly so the fit and the tissues underneath can be checked.
Dentures collect plaque, stain and bacteria in much the same way natural teeth do. Without daily care they can start to smell, look dull and irritate the gums they rest on. The good news is that a proper routine takes only a few minutes a day. This guide walks through that routine, what to use and what to avoid, how to care for partial dentures, and when a denture problem needs a dental visit.
How do you clean dentures every day?
A simple routine, done consistently, keeps most denture problems away.
1. Rinse after eating
Take the denture out after meals and run cool or lukewarm water over it to clear away food. Rinse your mouth as well. This only takes a moment, and it stops food from sitting under the denture and rubbing against your gums.
2. Brush the denture once a day
Stand over a sink filled with a few centimetres of water, or lay a folded towel in the sink. Dentures can crack or chip if they slip from wet hands onto a hard surface.
Use a denture brush or a soft toothbrush and a denture cleanser, mild dish soap or plain hand soap. Brush every surface gently:
- the outside of the teeth,
- the chewing surfaces,
- the fitting surface that sits against your gums or palate, and
- any clasps or metal parts on a partial denture.
The fitting surface matters most. It sits against your tissues all day and is where plaque and yeast tend to build up.
3. Soak overnight
Take the denture out before bed and place it in a clean container of cool water or a denture-soaking solution. Keeping it moist helps it hold its shape. Rinse it well before putting it back in your mouth.
4. Clean your mouth in the morning
Before you put the denture back in, brush your gums, tongue and palate gently with a soft toothbrush, or wipe them with a clean damp cloth. If you have natural teeth, brush them with fluoride toothpaste and clean between them.
What should you use to clean dentures, and what should you avoid?
Denture materials are softer than natural enamel, so products made for teeth can damage them.
| Use | Avoid |
|---|---|
| Soft denture brush or soft toothbrush | Stiff or hard-bristled brushes |
| Denture cleanser, mild dish soap or hand soap | Regular or whitening toothpaste |
| Cool or lukewarm water | Hot or boiling water |
| Denture-soaking solution or plain water | Bleach, especially on dentures with metal parts |
| Soaking products used as the label directs | Household cleaners or mouthwash as a soak |
| A clean, covered denture container | Wrapping dentures in a tissue or napkin |
A few of these deserve an explanation:
- Toothpaste contains mild abrasives that polish enamel but scratch denture acrylic. Scratches dull the surface and give stain and bacteria places to hide.
- Hot water can soften and warp the denture base, changing how it fits.
- Bleach can lighten the pink base, weaken the material and corrode metal clasps and frameworks.
- Tissues and napkins are the most common way dentures get thrown out by accident, especially in restaurants.
Should you sleep with dentures in?
In most cases, no. Taking dentures out overnight gives your gums and palate a rest from pressure and lets saliva reach the tissues. People who wear dentures day and night are more prone to red, irritated gums and fungal infection under the denture, sometimes called denture stomatitis.
There are exceptions. If you have just received an immediate denture after extractions, your dentist may ask you to keep it in for the first day or night. Follow the instructions you were given, and ask if you are unsure.
How do you soak dentures overnight?
Soaking keeps the denture moist and loosens debris, but it does not replace brushing. Soaking alone leaves behind the sticky plaque film that only brushing removes.
- Plain water keeps the denture from drying out.
- Denture-soaking tablets or solutions help freshen and loosen stains. Use them only as the package directs, and choose one that is suitable for your type of denture, especially if it has metal parts or a soft liner.
- Rinse thoroughly before wearing the denture again. Soaking solutions are not meant to be swallowed.
- Change the water or solution every day, and wash the container regularly so it does not become a source of bacteria.
If your denture has a soft liner, ask your dentist which products are safe for it. Some cleansers can harden or stain soft liners over time.
How do you clean a partial denture and the teeth that hold it?
A partial denture is cleaned the same way as a complete denture, with extra attention to the clasps and any metal framework. Brush these gently, since plaque gathers where they touch your teeth.
The natural teeth that hold a partial denture need special care. Clasps and denture edges can trap plaque against them, which raises the risk of decay and gum disease on the very teeth the denture depends on.
- Take the partial out before brushing, so you can reach every surface of your teeth.
- Brush your natural teeth twice a day with fluoride toothpaste.
- Clean between your teeth once a day with floss or small interdental brushes.
- Pay attention to the side of each anchor tooth that the clasp touches.
If you are still deciding between types of dentures, complete dentures vs partial dentures explains how each works.
How do you care for your gums and mouth under dentures?
The tissues under a denture need daily care too. Healthy gums help the denture fit and feel better.
- Brush or wipe your gums, tongue and palate each morning. This removes plaque, freshens your breath and stimulates circulation.
- Check your mouth now and then for sore spots, redness, white patches or lumps.
- Give your gums rest by leaving the denture out overnight.
- Drink water through the day if your mouth feels dry, since a dry mouth can make dentures less comfortable. Ask your dentist or physician if a medication may be causing dryness.
How do you remove stains and buildup from dentures?
Daily brushing and overnight soaking prevent most stains. Coffee, tea, red wine and tobacco tend to stain dentures faster, and hard white or yellow tartar can form if plaque is left in place.
Do not scrape tartar off with a knife or scouring pad, and do not try stronger chemicals at home. These can scratch or weaken the denture. Bring it to your dental visit instead. Your dentist can check it and advise on cleaning, and the office can explain what professional cleaning or polishing of the denture involves.
How do you clean off denture adhesive?
If you use a denture adhesive, remove it every day.
- Take the denture out and rinse it under lukewarm water.
- Brush the fitting surface with a denture brush to lift the adhesive.
- Wipe any remaining adhesive from your gums with a damp cloth or soft toothbrush, or rinse with warm water.
Needing more and more adhesive to keep a denture in place is a sign it may no longer fit well. Our article on why dentures become loose explains why this happens and what can be done.
What mistakes can damage dentures?
Most denture damage happens outside the mouth. Watch out for:
- dropping them while cleaning over a bare sink,
- leaving them out to dry on the counter,
- using hot water to “sterilize” them,
- leaving them within reach of pets, which may chew them,
- bending clasps yourself to tighten a partial,
- gluing broken pieces with household glue, and
- wearing a denture that has cracked, which can make the crack worse or injure your gums.
What should you do if a denture cracks or a tooth comes off?
Stop wearing a denture that is cracked or broken if it has sharp edges or no longer fits. Keep all the pieces, store them moist in a container, and call a dental office. Do not glue, file or bend the denture yourself. Home repairs often make a proper repair impossible, and some adhesives are not safe in the mouth.
Your dentist will examine the denture and explain whether it can be repaired, relined or needs to be replaced, along with the estimated fees.
How do you care for dentures for a family member?
Many adults help a parent, spouse or relative with denture care, at home or in a care setting. A few tips make it easier:
- Label the denture container with the person’s name, and ask the dentist about marking the denture itself if it may be misplaced.
- Remove and clean the denture daily, following the same steps above.
- Check the mouth for sore spots, since some people cannot easily report pain.
- Watch for changes in eating, speech or mood, which can signal a denture that is loose or hurting.
- Keep regular dental visits. Our office sees seniors and can accommodate patients with special needs.
Do new or immediate dentures need different care?
In the first weeks with a new denture, your gums are adjusting, and immediate dentures placed after extractions sit on healing tissue. Follow the instructions you receive at your fitting, which may include specific rinses and when to start taking the denture out overnight. Expect a few adjustment visits. Our guide on how long it takes to adjust to new dentures describes what is normal in those first weeks.
How often should denture wearers see a dentist?
Regular visits still matter when you wear dentures, even if you have no natural teeth. At a checkup, your dentist may:
- check the fit and bite of the denture,
- look for sore spots, irritation or infection under the denture,
- examine the soft tissues of the mouth, including an oral cancer screening,
- check the teeth that support a partial denture, and
- advise whether the denture needs relining or replacement.
The ridge under a denture changes slowly over the years, so a denture that fit well at first can gradually loosen. Many of these changes are painless, which is why routine dental exams are worth keeping.
How long do dentures last?
Dentures can last for a number of years with good care, but they do not last forever. The teeth wear down, the base can stain or weaken, and the shape of the mouth changes. A reline can refit the base to your gums, and sometimes a new denture is the better option. Your dentist can tell you which applies at your checkups.
Does insurance or the CDCP cover denture care?
Coverage depends on your plan. Many private plans include some coverage for dentures, relines and repairs, often with limits on how frequently they are covered. The office can send a predetermination to your insurer before treatment.
Under the Canadian Dental Care Plan (CDCP), complete dentures are covered, and partial dentures require preauthorization. Coverage details can change, so check the current CDCP coverage list or ask our team. If you are coming in under the CDCP, see what to bring to a CDCP dental appointment. The Canada Revenue Agency also lists dentures as an eligible medical expense for the medical expense tax credit.
When should you contact a dentist about your dentures?
Book a visit if you notice:
- sore spots or ulcers that do not heal within a week or two,
- redness, swelling or white patches under the denture,
- a bad smell or taste that remains despite careful cleaning,
- a denture that is loose, rocks or needs more adhesive than before,
- clicking, difficulty chewing or changes in your speech,
- a crack, chip, missing tooth or loose clasp, or
- pain in the teeth that support a partial denture.

Frequently asked questions
Can I use regular toothpaste on my dentures?
No. Standard toothpaste is abrasive enough to scratch denture acrylic, and the scratches then hold stain and bacteria. Use a denture cleanser, mild dish soap or hand soap with a denture brush instead.
Do soaking tablets replace brushing?
No — soaking loosens debris and freshens, but only mechanical brushing removes the plaque film that builds on dentures just as it does on teeth. Use both: brush daily, soak overnight.
Why does my denture smell even though I clean it?
Persistent odour usually means plaque or fungal buildup in scratches or on the fitting surface, or inflammation of the tissues underneath. A professional cleaning of the denture and an examination of your gums will usually identify the source.
My denture cracked. Can I glue it?
No — household adhesives are toxic and usually ruin the possibility of a proper repair. Keep the pieces, keep them moist, and contact a dental office about assessment and the appropriate repair route.
Should I sleep with my dentures in?
Usually not. Most dentists recommend taking dentures out overnight so the gums and palate can rest and saliva can reach the tissues. Wearing dentures around the clock is linked with gum irritation and fungal infection under the denture. If you have been told to keep a new or immediate denture in for the first night, follow those instructions.
How often should I see a dentist if I wear dentures?
Regular visits still matter, even with no natural teeth. Your dentist checks the fit of the denture, looks for sore spots or changes in the gums, and examines the soft tissues of the mouth. Your dentist will suggest a visit schedule based on your needs; partial denture wearers usually need checkups and cleanings for their remaining teeth as well.
