What Are Denture Cleaning Tablets and How Does Steradent Active Plus Help?

 

Keeping your dentures clean is just as important as caring for natural teeth. Bacteria, plaque, and food debris can accumulate on denture surfaces throughout the day, and without proper cleaning, this can lead to bad breath, gum irritation, and even oral infections. Denture cleaning tablets like Steradent Active Plus offer a simple, effective way to maintain denture hygiene between brushing. At just £2.09, this is an accessible everyday essential for anyone who wears full or partial dentures. You can browse the full range of products in our dental products collection for more oral care options.

Steradent Active Plus is a well-established over-the-counter denture cleanser available without a prescription. It works through an effervescent action — the tablet fizzes when dropped into water, releasing oxygen that penetrates denture surfaces to loosen debris and kill bacteria. It is suitable for daily use and is designed to help keep dentures looking and feeling fresh.

 

How Does Steradent Active Plus Work to Clean Dentures?

 

The cleaning action of Steradent Active Plus relies on a combination of effervescence and mild oxidising chemistry. When the tablet dissolves in warm water, it produces a fizzing solution that works in several ways:

  • Oxygen bubbles are released, physically dislodging food particles and plaque from denture surfaces and crevices
  • A mild bleaching agent helps to lift surface stains caused by tea, coffee, and food
  • Antibacterial components in the solution reduce the bacterial load on the denture, helping to prevent odour
  • The effervescent action reaches areas that a toothbrush may not easily access, such as the underside of the denture plate

This combination of mechanical and chemical action makes it a practical daily cleaning option. It does not replace brushing — the NHS recommends brushing dentures with a soft brush and non-abrasive cleaner — but it complements your routine effectively.

 

Who Should Use Steradent Active Plus Tablets?

 

Steradent Active Plus is suitable for most adults who wear removable dentures. It is particularly useful for people who want a quick, no-fuss daily soak to supplement their brushing routine. That said, it is not appropriate for everyone.

  • Adults wearing full (complete) removable dentures
  • Adults wearing partial dentures (check compatibility with metal components first)
  • People who want to reduce denture-related bad breath
  • Those looking to prevent staining from tea, coffee, or food

It is not intended for use by children, and the soaking solution must never be placed in the mouth or swallowed. If you have any concerns about which denture cleaner is right for you, speak to your dentist or pharmacist.

 

How Does Steradent Active Plus Compare to Other Denture Cleaners?

 

Feature Steradent Active Plus Standard Denture Paste
Form Effervescent tablet Paste/cream
Antibacterial action Yes Variable
Reaches crevices Yes (via fizzing action) Limited
Stain removal Yes Mild

 

Is Steradent Active Plus Suitable for All Denture Types?

 

Most people can use denture cleaning tablets safely with their removable dentures. However, if your partial denture contains metal clasps or components, it is worth checking with your dentist before using any effervescent cleaner, as some formulations can affect certain metal alloys over time. Steradent Active Plus is generally considered suitable for acrylic dentures. Always follow the manufacturer's instructions regarding soak time, as leaving dentures in the solution for longer than recommended is not beneficial and may affect the denture material.

Store the tablets in a cool, dry place away from moisture and direct sunlight. Keep them out of reach of children at all times. If you are also managing other aspects of your oral health, our oral health collection includes a range of complementary products.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of Steradent Active Plus Tab

 

What Is Steradent Active Plus and What Is It Used For?

 

Steradent Active Plus is an effervescent denture cleaning tablet used to clean, deodorise, and help maintain the appearance of removable dentures. Each tablet dissolves in water to create a soaking solution that removes food debris, surface stains, and bacteria from both full and partial dentures. It is an over-the-counter product available without a prescription and is intended for daily use as part of a complete denture care routine.

The NHS advises that dentures should be cleaned every day to prevent the build-up of plaque and bacteria, which can cause bad breath and increase the risk of oral infections such as denture stomatitis — a fungal condition caused by Candida species. Using a denture cleaning tablet alongside brushing helps to address areas that a brush alone may not reach.

 

What Do You Need to Know Before Using Steradent Active Plus?

 

Before using Steradent Active Plus, there are some important points to be aware of. This product is for external use only — the soaking solution must never be placed in the mouth or swallowed.

Do not use Steradent Active Plus if:

  • You are allergic to any of the ingredients, including sodium perborate or citric acid
  • The product is intended for use by a child — it is for adults only
  • Your dentures are fixed (implant-retained) and cannot be removed for soaking

Warnings and precautions:

  • Always rinse dentures thoroughly under running water before placing them back in your mouth
  • Do not use boiling water — warm water is sufficient and prevents damage to the denture material
  • If your partial denture contains metal components, consult your dentist before use
  • Keep tablets dry and away from children — they can cause harm if swallowed
  • Avoid prolonged skin contact with the dissolved solution; wash hands after handling

Known interactions:

  • No significant drug interactions are known for this topical denture cleanser
  • The product is not absorbed into the body when used as directed

 

How Should You Use Steradent Active Plus Correctly?

 

Using Steradent Active Plus correctly is straightforward, but following the steps in order ensures the best cleaning result and protects your dentures from damage.

  1. Remove your dentures from your mouth
  2. Fill a clean glass or denture bowl with enough warm (not boiling) water to fully submerge the dentures
  3. Drop one Steradent Active Plus tablet into the water and allow it to dissolve fully
  4. Place your dentures into the solution and leave to soak for the time stated on the packaging (typically around 3–5 minutes for a quick clean, or longer for a deeper soak — follow the label)
  5. Remove the dentures and rinse them thoroughly under running cold or lukewarm water
  6. Brush the dentures gently with a soft denture brush before wearing if desired
  7. Discard the used solution — do not reuse it
Indication Age Group Dose Frequency
Daily denture cleaning Adults 1 tablet per glass of warm water Once daily
Deeper stain removal Adults 1 tablet per glass of warm water As needed, following label guidance

What Are the Possible Side Effects of Steradent Active Plus?

 

When used as directed, Steradent Active Plus is generally well tolerated. Side effects are uncommon, but it is important to know what to look out for.

Common side effects (if the solution contacts oral tissue):

  • Mild gum irritation or soreness if dentures are not rinsed thoroughly before wearing
  • Temporary taste alteration if residual solution remains on the denture

Less common side effects:

  • Skin irritation or redness on hands with prolonged contact with the dissolved solution
  • Nausea or stomach discomfort if the solution is accidentally swallowed

If you experience any allergic reaction — such as swelling, rash, or difficulty breathing — stop use immediately and seek urgent medical attention. This is rare but requires prompt action.

 

How Should You Store Steradent Active Plus Tablets?

 

Correct storage keeps the tablets effective and safe. Moisture is the main enemy — even a small amount of humidity can cause the tablets to begin fizzing prematurely inside the pack.

  • Store below 25°C in a cool, dry place
  • Keep away from direct sunlight and sources of heat
  • Keep the pack tightly closed after each use
  • Do not store in a bathroom cabinet where steam and humidity are common
  • Keep out of reach and sight of children at all times
  • Do not use after the expiry date printed on the packaging

Frequently Asked Questions

Where can I buy Steradent Active Plus tablets online in the UK?

You can buy Steradent Active Plus tablets directly from Cured Pharmacy, a GPhC-registered UK online pharmacy, for just £2.09. No prescription is required as this is a general sale dental hygiene product. Browse our full dental products collection for more denture care options.

How do Steradent Active Plus tablets work to clean dentures?

When dropped into warm water, Steradent Active Plus tablets dissolve and release oxygen bubbles through an effervescent reaction. This fizzing action physically dislodges plaque, food debris, and bacteria from denture surfaces, including hard-to-reach crevices. A mild oxidising agent in the formula also helps to lift surface stains caused by tea, coffee, and food.

How do I use Steradent Active Plus step by step?

Remove your dentures, fill a glass with enough warm water to submerge them, then drop in one tablet and let it fully dissolve. Place your dentures in the solution and soak for the time stated on the packaging, then remove and rinse thoroughly under running water before wearing. Never place the tablet or the solution directly in your mouth.

How often should I use Steradent Active Plus denture cleaning tablets?

Steradent Active Plus is designed for daily use to maintain consistent denture hygiene and prevent the gradual build-up of plaque and stains. Using one tablet per day as part of your regular denture care routine gives the most reliable results. The NHS recommends cleaning dentures every day alongside brushing.

Are Steradent Active Plus tablets safe for partial dentures with metal clasps?

Steradent Active Plus is generally suitable for acrylic full and partial dentures, but if your partial denture contains metal components such as cobalt-chrome clasps, it is advisable to check with your dentist before regular use. Some effervescent cleaners can affect certain metal alloys over time with prolonged exposure. Your dentist can confirm the most appropriate cleaner for your specific denture type.

Can Steradent Active Plus tablets cause any side effects?

Side effects are uncommon when the product is used correctly. The most likely issue is mild gum irritation if dentures are not rinsed thoroughly after soaking, allowing residual solution to contact oral tissue. Skin irritation on the hands is possible with prolonged contact with the dissolved solution, so washing your hands after handling is sensible.

What happens if I accidentally swallow the Steradent soaking solution?

The soaking solution is not intended for ingestion and should never be swallowed. If a small amount is accidentally ingested, it may cause nausea or mild stomach discomfort. If a larger quantity is swallowed, or if symptoms develop, seek medical advice promptly — you can call NHS 111 for guidance.

What is the best time of day to use Steradent Active Plus?

Many people find it most convenient to soak their dentures overnight, though Steradent Active Plus can also be used for a shorter daytime soak. If you prefer to wear your dentures at night, a morning soak while you eat breakfast or a brief soak during the day works equally well. Consistency matters more than timing — daily use is the key factor.

Who is eligible to use Steradent Active Plus tablets?

Steradent Active Plus is suitable for adults who wear removable full or partial dentures and want to maintain daily denture hygiene. It is not suitable for children, and it should not be used by anyone with a known allergy to any of the ingredients. If you are unsure whether this product is right for you, speak to your pharmacist or dentist before use.

What are the alternatives to Steradent Active Plus for cleaning dentures?

Alternatives include other effervescent denture cleaners such as Polident tablets, as well as denture cleaning pastes and specialist denture brushes. The NHS recommends using a non-abrasive denture cleaner alongside a soft brush for daily cleaning. Your dentist can advise on the most suitable option based on your denture material and individual needs.

Can I use Steradent Active Plus every day long term?

Yes, Steradent Active Plus is formulated for daily use and is intended to be part of your ongoing denture care routine rather than an occasional treatment. Long-term daily use helps to prevent stain accumulation and reduces bacterial load on the denture surface. If you notice any changes to your denture material over time, consult your dentist.

Does Steradent Active Plus remove bad breath caused by dentures?

Yes, one of the key benefits of using denture cleaning tablets daily is the reduction of odour-causing bacteria on the denture surface, which can contribute significantly to bad breath. Thorough rinsing after soaking and regular brushing of the dentures also help. If bad breath persists despite good denture hygiene, speak to your dentist as it may indicate an underlying oral health issue.

Is Steradent Active Plus the same as regular Steradent tablets?

Steradent Active Plus is a specific formulation within the Steradent range, designed with an enhanced effervescent action for more thorough stain and bacteria removal compared to the standard Steradent formula. Always check the product label to confirm you have the correct variant for your needs. Both are available as over-the-counter products without a prescription.

What are the latest findings on denture hygiene and oral health?

Research continues to highlight the link between poor denture hygiene and conditions such as denture stomatitis, a fungal infection caused by Candida species that affects a significant proportion of denture wearers. The NHS and dental organisations consistently recommend daily cleaning with an effervescent cleaner alongside brushing to reduce this risk. Good denture hygiene is also associated with better overall oral comfort and reduced gum irritation. You can find further oral care support in our oral health collection.

How should I store Steradent Active Plus tablets to keep them effective?

Store Steradent Active Plus tablets in a cool, dry place below 25°C, away from direct sunlight and sources of moisture. Avoid keeping them in a bathroom cabinet where steam can cause the tablets to deteriorate prematurely. Always reseal the pack tightly after use and keep it out of reach of children.

How Should You Use Steradent Active Plus?

Using Steradent Active Plus correctly takes only a few minutes and makes a real difference to denture cleanliness. Always remove your dentures before starting, and never place the tablet or the dissolved solution directly in your mouth.

What Is the Correct Dose of Steradent Active Plus?

The dose is straightforward: one tablet per cleaning session, dissolved in a sufficient volume of warm water to submerge the dentures fully. Using more than one tablet per session does not improve the cleaning result and is not recommended.

When Is the Best Time to Use Steradent Active Plus?

There is no single "correct" time — the best time is whichever fits most naturally into your daily routine so that you use it consistently. Many people soak their dentures first thing in the morning while eating breakfast, or during a period when they do not need to wear them. If you remove your dentures at night, a brief soak in the morning before wearing them is a practical option. Consistency is what matters most for maintaining good denture hygiene.

How Long Can You Use Steradent Active Plus For?

Steradent Active Plus is designed for ongoing daily use for as long as you wear removable dentures. There is no recommended maximum duration of use — it is a maintenance product rather than a short-term treatment. If you notice any changes to your denture material, unusual discolouration, or persistent oral discomfort, speak to your dentist who can assess whether your cleaning routine needs adjusting.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Steradent Active Plus?

Steradent Active Plus is generally very well tolerated when used as directed. The most commonly reported issue is not a direct side effect of the product itself, but rather a consequence of inadequate rinsing after soaking. If residual cleaning solution remains on the denture surface when it is placed back in the mouth, it can cause mild irritation to the gum tissue underneath.

  • Mild gum soreness or irritation from residual solution on inadequately rinsed dentures
  • Temporary altered taste if solution residue remains on the denture

What Are the Less Common Side Effects of Steradent Active Plus?

Less common side effects are typically associated with direct contact between the dissolved solution and skin or mucous membranes. These are avoidable with careful handling.

  • Skin redness or mild irritation on the hands after prolonged contact with the dissolved solution
  • Nausea or mild stomach discomfort if the solution is accidentally swallowed
  • Eye irritation if the solution splashes into the eyes — rinse immediately with clean water if this occurs

What Are the Serious Side Effects of Steradent Active Plus?

Serious side effects are rare but possible, particularly in individuals with a sensitivity or allergy to any of the ingredients. Sodium perborate, one of the active components, can cause an allergic reaction in susceptible individuals. Signs of a serious allergic reaction (anaphylaxis) include swelling of the face, lips, or throat, difficulty breathing, a widespread rash, or dizziness. If you experience any of these symptoms, stop using the product immediately and seek urgent medical attention by calling 999 or going to your nearest A&E department.

What Should You Do If You Experience Side Effects?

For mild side effects such as gum irritation, ensure you are rinsing your dentures thoroughly under running water for at least 30 seconds after soaking before placing them back in your mouth. If skin irritation occurs, wash the affected area with soap and water. For any side effect that persists, worsens, or concerns you, stop using the product and speak to your pharmacist or GP. You can also report suspected side effects to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

Can Steradent Active Plus Interact With Other Medicines?

No significant interactions with medicines are known for Steradent Active Plus when used as directed as a topical denture soaking solution. Because the product is not intended to be swallowed and is not absorbed into the body during normal use, systemic drug interactions are not expected. If you have any concerns about using this product alongside other treatments, speak to your pharmacist for personalised advice.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
