You shouldn’t sleep with your dentures in on a regular basis, because taking them out for 6 to 8 hours a night lets your gums rest and lowers the risk of fungal infections, gum irritation and bad breath. Sleeping in dentures now and then isn’t an emergency, but making it a habit has been linked with denture stomatitis and, in older adults, a higher risk of pneumonia. The main exception is the first day or two after getting immediate dentures, when your dentist may ask you to keep them in, so always follow the instructions you got with your dentures.
Lots of people sleep in their dentures because they feel self-conscious without them, even at home. Others just forget. Both are completely understandable, and both are fixable with a few small changes.
At Ardagh Family Dentistry Barrie, we talk with denture wearers about this at almost every visit. A night routine takes about 3 minutes, and it does a lot for your mouth.
Healthy gums under a denture are part of everyday preventive dental care, the same as cleanings are for natural teeth. If you’re getting dentures after a tooth extraction, the first few weeks have their own rules, and we’ll go through them with you. If your dentures feel loose or sore, it’s worth an adjustment, and you can book an appointment online anytime.
Quick answer
Take dentures out at night, clean them, and store them in water or a denture-soaking solution. Rinse your mouth and gently brush your gums and tongue before bed. Put the dentures back in the morning after rinsing them.
Why should dentures come out at night?
1. Your gums need a break
Dentures press on the gums and bone all day. Removing them at night lets blood flow return fully and gives the tissue time to recover. Constant pressure can speed up bone shrinkage, which makes dentures loosen faster.
2. Fungal infections like warm, dark places
The space under a denture is warm and moist. Overnight, with less saliva flowing, yeast called Candida can multiply. The result is denture stomatitis: red, sore, inflamed tissue under the denture, especially on the roof of the mouth.
3. Higher pneumonia risk in older adults
A study of older adults in Japan, published in the Journal of Dental Research, found that those who wore dentures overnight had about twice the risk of pneumonia compared with those who removed them. The likely reason is bacteria from the denture being breathed into the lungs during sleep.
4. Bad breath and plaque buildup
Dentures collect plaque just like natural teeth. Leaving them in overnight lets bacteria build up, which often shows up as morning bad breath and a bad taste.
Is it ever okay to sleep with dentures in?
| Situation | Usual advice |
|---|---|
| First 24 to 48 hours with immediate dentures | Often kept in, as directed by your dentist, to control swelling and bleeding |
| Occasional nights, like travel or a nap | Usually fine if it’s rare, but clean them well the next morning |
| Some partial dentures with clasps | Usually removed, but follow your dentist’s advice |
| Specific medical or jaw reasons | Some patients get personalized instructions from their dentist or physician |
| Every night as a habit | Not recommended |
A simple night-time denture routine
- Remove the dentures over a folded towel or a sink filled with water, so they don’t break if dropped.
- Rinse them under cool running water to remove loose food.
- Brush them with a soft denture brush and a non-abrasive denture cleaner. Regular toothpaste can scratch them.
- Soak them overnight in plain water or a denture-soaking solution. Never let them dry out, or they can warp.
- Clean your mouth. Brush your gums, tongue and roof of your mouth gently with a soft toothbrush. Brush any natural teeth normally.
- In the morning, rinse the dentures well before putting them back in, especially if you used a soaking solution.
Safety note: Never soak or rinse dentures in hot or boiling water, as it can warp them. Don’t use bleach on dentures with metal parts, and keep soaking solutions away from children, since some can be harmful if swallowed.
Signs you’ve been sleeping in your dentures too much
- Red, swollen or sore gums under the denture
- White patches or a burning feeling on the roof of the mouth
- Cracks or redness at the corners of your mouth
- Persistent bad breath or a bad taste in the morning
- Dentures feeling looser than they used to
Most of these improve within a couple of weeks of a better routine. Fungal infections may need a prescribed antifungal treatment.
What if you feel embarrassed taking them out?
This comes up more than you’d think. Some people don’t want their partner to see them without teeth. That’s a real feeling, and it deserves a real answer.
- Remove them right before you turn off the light, and put them back first thing in the morning
- Keep the denture cup on your bedside table so it’s within reach
- Talk to your partner about it; most people are far more understanding than we expect
- Ask your dentist about implant-supported options if loose or removable teeth really bother you
Complete vs partial dentures: does it change the rules?
| Complete dentures | Partial dentures | |
|---|---|---|
| Remove at night? | Yes | Yes, in most cases |
| Main overnight risk | Stomatitis, bone pressure | Plaque on clasps damaging natural teeth |
| Cleaning focus | Fitting surface and gums | Clasps, plus natural teeth they rest on |
| Natural teeth care | Not applicable | Brush and floss natural teeth carefully every night |
Denture cleaning: what to use and what to avoid
| Use | Avoid |
|---|---|
| Soft denture brush or soft toothbrush | Hard-bristled brushes |
| Mild dish soap or denture paste | Regular whitening toothpaste (too abrasive) |
| Denture-soaking tablets or plain water | Hot or boiling water |
| Cool or lukewarm water for rinsing | Bleach, especially on metal partials |
| A towel or water-filled sink under you while cleaning | Cleaning over a hard, empty sink |
When should dentures be relined or replaced?
Your jawbone slowly changes shape after teeth are lost. Dentures that fit perfectly at first can loosen over a few years. Signs it’s time for a check:
- You need more adhesive than before
- Food gets under the denture often
- Sore spots keep coming back
- The denture rocks or clicks when you talk
- Your face looks more sunken around the mouth
- The teeth on the denture look worn, chipped or stained
A reline reshapes the fitting surface to match your gums. A replacement may be needed when the teeth are worn or the base is cracked.
Making dentures more comfortable during the day
- Rinse your dentures and mouth after meals when you can.
- Cut food into smaller pieces and chew on both sides at once.
- Drink water through the day, especially if your mouth feels dry.
- Use adhesive sparingly, a few small dots, not a thick strip.
- Book an adjustment for any sore spot that lasts more than a few days.
Comfortable dentures are much easier to take out and put back in, which makes the night routine easier too.
What to do if you travel with dentures
Travel is when night routines fall apart. Packing a small kit keeps things simple.
- A travel denture case with a tight lid
- A soft denture brush and a small bottle of denture cleaner
- A few soaking tablets in a sealed bag
- A soft toothbrush for your gums and any natural teeth
- Bottled water for soaking if tap water quality is uncertain
Never wrap dentures in a tissue or napkin at a restaurant or hotel. That’s how most lost dentures end up in the garbage.
Implant-supported dentures: different rules?
Snap-on dentures held by implants are still removable, and most should still come out at night for cleaning and to let the gums rest. Fixed implant bridges that only a dentist can remove are cleaned in place with a water flosser and special brushes. Your dentist will tell you which type you have and how to care for it.
Myths about dentures at night
Myth: Dentures don’t need cleaning because they can’t get cavities
The denture can’t decay, but it collects plaque, bacteria and yeast that affect your gums, remaining teeth and breath.
Myth: Leaving them in keeps your face from sagging
Wearing dentures overnight doesn’t stop bone loss. Constant pressure may actually speed it up.
Myth: Dentures last forever
Your mouth changes over time. Most dentures need relining every few years and replacing every 5 to 10 years.
Myth: If they don’t hurt, they fit fine
Dentures can loosen slowly without pain. Regular checks catch fit problems early.
Real patient experiences
The burning palate. A patient in her 70s has a sore, burning roof of the mouth. She’s been sleeping in her upper denture for years. Antifungal treatment plus a new night routine clears it up in a few weeks.
The immediate denture. Another patient gets immediate dentures after extractions. He’s told to keep them in for the first night, then start removing them nightly. His gums heal well.
The forgetful sleeper. A third patient keeps forgetting. Moving her denture cup next to her phone charger fixes it, because she sees it every night.
Why regular denture check-ups matter
Even with no natural teeth, you should see a dental professional regularly. Visits check denture fit, gum health and screen for oral cancer.
Care should come from licensed dental professionals registered with the Royal College of Dental Surgeons of Ontario (RCDSO) or the appropriate regulatory college.

Frequently asked questions
How many hours a day should dentures be taken out?
Most dentists recommend removing dentures for about 6 to 8 hours every day, usually overnight while you sleep, to let your gums rest.

One night isn’t a problem. Clean your dentures and mouth well in the morning, and try to remove them at night going forward.

Yes. Store them in plain water or a denture-soaking solution so they don’t dry out and warp. Rinse them well before putting them back in.
Can sleeping in dentures cause pneumonia?
Research in older adults has linked overnight denture wearing with a higher risk of pneumonia, likely from breathing in bacteria from the denture during sleep.
Should I sleep in my dentures right after extractions?
Often for the first 24 to 48 hours with immediate dentures, if your dentist tells you to. After that, most patients begin removing them at night.
