Clean your dentures every day, just like natural teeth

Dentures need daily cleaning to remove food, plaque, and bacteria. The routine is straightforward: rinse them after meals, brush them at least once a day with a soft-bristled brush and denture cleaner, and soak them overnight in water or a denture solution. This keeps them looking good, prevents odor, and stops bacteria from building up.

The difference from natural teeth is that dentures are made of acrylic or metal, not enamel. Harsh abrasives and hot water can crack or warp them. That means you need to use products made for dentures, not regular toothpaste, and you need to handle them gently.

Most people find that a straightforward routine takes five minutes a day and prevents expensive repairs down the road. The cost of a denture cleaner tablet or brush is far less than replacing a cracked denture.

Key Takeaways

  • Rinse dentures under cool running water after every meal to remove loose food and debris.
  • Brush dentures daily with a soft-bristled denture brush and denture-specific cleaner, never regular toothpaste or bleach.
  • Soak dentures overnight in water or a denture solution to keep them moist and kill bacteria.
  • Handle dentures over a towel or sink filled with water so they do not break if you drop them.
  • See your dentist once a year to check the fit and have them professionally cleaned.

Rinsing and brushing after meals

After you eat, take out your dentures and rinse them under cool running water. This removes loose food particles and prevents them from hardening on the surface. Do this even if you only had a snack — small bits of food left behind can trap bacteria and cause odor.

Once a day, usually before bed, brush your dentures with a soft-bristled denture brush. Wet the dentures first, explore a denture-specific cleaner (not regular toothpaste), and brush all surfaces — the top, bottom, and the side that sits against your gums. Brush gently in a circular motion. Rinse thoroughly under cool water until no cleaner remains.

If you wear dentures during the day and remove them at night, you can do your main brushing at night. If you wear them all day, brush them in the morning and again before bed.

Soaking dentures overnight

Dentures need to stay moist. When they dry out, they can crack, warp, or lose their shape. Soak them overnight in a denture solution or plain cool water. Most people use a denture cup — a small container designed for this purpose — and fill it with enough liquid to cover the dentures completely.

Denture soaking solutions come in tablet or liquid form. Popular brands include Polident, Efferdent, and Steradent. These solutions kill bacteria and help remove stains. Follow the package directions for how long to soak — usually four to eight hours, though overnight is fine. In the morning, rinse the dentures under cool water before putting them back in.

If you do not have denture solution, plain cool water works. Change the water daily. Do not use hot water, as heat can warp the acrylic or metal base.

What to avoid when cleaning dentures

Never use regular toothpaste on dentures. Toothpaste contains abrasives that scratch acrylic and can dull the finish. Never use bleach, even diluted, as it can weaken the material and discolor it. Do not use a hard-bristled toothbrush — it will scratch the surface.

Avoid very hot water. Acrylic dentures can warp if soaked in hot water or placed in a dishwasher. Some metal dentures can handle warmer water, but cool water is always safe. Never use ultrasonic cleaners or denture-cleaning machines at home without checking with your dentist first — they can damage some types of dentures.

Do not leave dentures dry for long periods. If you need to remove them during the day, keep them in a cup of water or denture solution. Dry dentures are brittle and more likely to crack if dropped.

Handling and storing dentures safely

Always handle dentures over a sink filled with water or over a towel. If you drop them on a hard floor, they can crack or break. A towel or water cushions the fall. Many people keep a small denture cup on their nightstand or bathroom counter so they have a safe place to put dentures when they remove them.

Store dentures in a cool, dark place — not in direct sunlight or near a heat source. A bathroom cabinet or nightstand drawer works well. Keep them in their soaking solution or in water so they do not dry out. If you travel, bring a small denture cup and a travel-size container of denture solution.

If you wear dentures only at night or part-time, soak them whenever they are not in your mouth. Do not leave them sitting on a shelf or counter dry.

Cleaning your mouth and gums while wearing dentures

Your natural gums and any remaining teeth still need care. Before putting in your dentures each morning, brush your gums, tongue, and the roof of your mouth with a soft toothbrush. This removes plaque and bacteria and keeps your mouth healthy. If you have any remaining natural teeth, brush and floss them as you normally would.

Rinse your mouth with water or mouthwash after meals, especially before putting dentures back in. This removes food particles and keeps your mouth fresh. If you notice redness, soreness, or irritation under your dentures, remove them and let your gums rest. If the irritation does not go away in a few days, contact your dentist.

Some people develop fungal infections (oral thrush) under dentures because the warm, moist environment under a denture can encourage fungal growth. Soaking dentures daily and keeping your mouth clean help prevent this. If you develop white patches or persistent soreness, see your dentist.

Professional cleaning and annual checkups

Visit your dentist once a year for a professional cleaning and to check how your dentures fit. Over time, your gums and jaw bone change shape, and dentures may become loose or uncomfortable. Your dentist can adjust the fit or recommend a reline — a procedure that adds material to the inside of the denture to make it fit better again.

Professional cleaning removes stains and buildup that daily brushing cannot. Your dentist has tools and solutions that are stronger than what you use at home. They can also spot cracks, chips, or other damage early, when repair is cheaper than replacement.

If your dentures break or crack, do not try to glue them yourself. Contact your dentist or a denture lab. Most repairs take a few days to a week. In the meantime, ask your dentist if you can wear an older pair of dentures or if they have a temporary solution.

Frequently Asked Questions

Can I use regular toothpaste to clean my dentures?

No. Regular toothpaste contains abrasives that scratch acrylic dentures and dull their finish. Use a denture-specific cleaner instead. These are gentler and made for the materials in dentures.

How long can I leave dentures out of water?

Dentures should not dry out for more than a few hours. If you remove them during the day, keep them in a cup of water or denture solution. Dry dentures become brittle and are more likely to crack if dropped.

What should I do if my dentures smell bad even after cleaning?

Odor usually means bacteria or fungus is growing. Make sure you are soaking them overnight in a fresh denture solution each day, and brush your gums and mouth before putting dentures back in. If the smell continues, see your dentist — you may have a fungal infection that needs treatment.

Can I sleep in my dentures every night?

Some people do, but dentists usually recommend removing dentures at night to let your gums rest and recover. If you do sleep in them, soak them for at least a few hours during the day. Talk to your dentist about what is best for your situation.

How often should I replace my dentures?

With proper care, dentures typically last five to eight years. Over time, the acrylic can become stained or cracked, and your jaw shape changes, making the fit loose. Your dentist can tell you when replacement or a major reline is needed.
