How to Clean Dentures Properly: The Complete Daily Care Guide (2026)

Why Denture Cleaning Matters More Than You Think

Your dentures sit against warm, moist gum tissue for 14 to 16 hours a day. Without proper daily cleaning, they collect the same plaque and bacteria as natural teeth — plus a fungus called Candida that thrives on acrylic surfaces.

The consequences of poor denture hygiene are not just cosmetic:

• Denture stomatitis (thrush): red, burning, inflamed gums under the denture — we cover this in detail in our guide to denture thrush and burning gums
• Persistent bad breath that mints and mouthwash cannot fix, because the odour source is the denture itself
• Staining and tartar build-up that makes even well-made teeth look old and artificial
• Damaged fitting surfaces from harsh cleaning, which leads to looseness and sore spots

The good news: proper denture care takes about five minutes a day. Here is the routine we recommend to every patient at our Oak Park clinic.

The Daily Denture Cleaning Routine (Step by Step)

Step 1: Remove and Rinse After Meals

After eating, take your dentures out and rinse them under cool or lukewarm running water to wash away loose food particles. This alone prevents most staining and odour problems.

Important: Fill the sink with water or lay a folded towel in the basin first. The single most common cause of broken dentures we see is a denture slipping from soapy hands onto a hard sink or tiled floor. If that happens to you, do not reach for glue — read our warning about superglue denture repairs first, then call us for a proper denture repair.

Step 2: Brush Once a Day — But Not with Toothpaste

Brush all surfaces of the denture daily with:

• A soft denture brush or soft-bristled toothbrush
• Mild liquid soap, dishwashing liquid, or a dedicated denture paste

Do not use regular toothpaste. This surprises almost everyone, but ordinary toothpaste is the most common cleaning mistake we see. Toothpaste contains abrasives designed for hard tooth enamel. Denture acrylic is much softer, and daily scrubbing with toothpaste creates thousands of microscopic scratches. Those scratches trap stains and bacteria, making the denture look duller and smell worse over time — the exact opposite of what you wanted.

Pay special attention to the fitting surface (the side that touches your gums). This is where plaque and fungus accumulate most.

Step 3: Soak Overnight

Unless your prosthetist has advised otherwise, dentures should come out at night and soak in:

• Plain water, or
• A denture-cleansing solution (tablets such as effervescent cleansers), used according to the packet directions

Soaking does two jobs. It keeps the acrylic from drying out and warping, and it gives your gum tissue a nightly rest, which dramatically reduces the risk of stomatitis. If you are tempted to leave them in around the clock, read why we advise against it in our guide to sleeping with dentures.

Step 4: Rinse Before Wearing Again

If you soaked in a cleansing solution, rinse the denture thoroughly under running water before putting it back in. Cleaning chemicals are designed for soaking, not for contact with your mouth.

Step 5: Clean Your Mouth Too

Before reinserting your dentures each morning:

• Brush any remaining natural teeth normally
• Gently brush your gums, tongue and palate with a soft brush, or wipe them with a damp cloth

This removes the plaque film on your gums and stimulates circulation in the tissue that supports your denture.

What NOT to Use on Your Dentures

These are the products and habits that bring dentures into our repair room:

If your denture has already lost its fit or its surface feels rough and stained, do not keep scrubbing harder — that makes it worse. A professional clean and polish restores the surface without removing material. Ask us about professional denture maintenance.

Special Cases: Partials, Flexible Dentures and Implant-Retained Dentures

Metal Partial Dentures (Chrome-Cobalt)

Partial dentures with metal frameworks need extra care around the clasps — the thin metal arms that grip your natural teeth. Brush gently along the clasps rather than across them, and never soak chrome partials in bleach-based or acidic solutions unless the product is specifically labelled safe for metal.

Flexible (Valplast) Dentures

Valplast flexible dentures are made from nylon, not acrylic, and they have their own rules. Abrasive cleaning dulls the semi-translucent finish that makes them look natural. Use only a soft brush with mild soap, and ideally a cleanser labelled suitable for flexible dentures. We explain more in our Valplast pros and cons guide.

Implant-Retained and Snap-On Dentures

If you have implant-retained dentures or snap-on dentures, clean the denture itself the same way — but you must also clean around the implant attachments in your mouth every day. Plaque left around implants can inflame the surrounding tissue. The nylon inserts inside the denture also wear over time and need periodic replacement, which is a quick clinic visit.

How Often Should Dentures Be Professionally Cleaned?

Even with perfect home care, dentures gradually accumulate hardened tartar (calculus) that home brushing cannot remove — exactly like natural teeth. We recommend a professional clean and check-up at least once a year, where we:

• Remove tartar and stains in an ultrasonic bath and re-polish the surface
• Check the fit — gum ridges change shape continuously, and a loose denture accelerates that change (see our denture reline guide)
• Inspect for hairline cracks and worn teeth before they become a broken denture at dinner

Because we have an on-site laboratory, cleaning, polishing and small repairs are usually done the same day.

Frequently Asked Questions

Can I use toothpaste to clean my dentures?

No. Standard toothpaste is too abrasive for denture acrylic and will scratch the surface, causing staining and odour over time. Use mild soap or a dedicated denture cleaner instead.

Should dentures be kept in water overnight?

Yes, unless your prosthetist tells you otherwise. Dentures should stay moist when out of the mouth. Soak them in plain water or a denture-cleansing solution overnight — never hot water.

How do I remove stubborn stains from my dentures?

Persistent tea, coffee or tobacco staining that survives daily brushing needs a professional ultrasonic clean and polish. Home remedies like bleach or vigorous scrubbing damage the denture and usually make staining return faster.

Why do my dentures smell even though I clean them?

Odour that survives daily brushing usually means bacteria and fungus have colonised microscopic scratches or porous areas, or tartar has built up on the fitting surface. A professional clean resolves this in most cases. If your gums are also red or burning, you may have denture stomatitis and should book an assessment.

Can I clean dentures with bleach or Milton?

We do not recommend it. Bleach can whiten the pink acrylic, corrode metal components, and damage soft liners. Purpose-made denture cleansers are inexpensive and formulated to be safe.
