How to Store and Clean Your Dentures to Avoid Denture Stomatitis

Learn how to properly store and clean your dentures to help prevent denture stomatitis. Practical advice on daily denture care, hygiene routines, and when to seek dental help.

Introduction

If you wear dentures, you may have noticed redness, soreness, or irritation on the roof of your mouth or along your gums. These symptoms can be uncomfortable and often prompt people to search online for answers. In many cases, these signs may be associated with a common condition known as denture stomatitis — a fungal infection that develops beneath dentures when oral hygiene and denture care routines are not maintained effectively.

Understanding how to properly store and clean your dentures is one of the most important steps you can take to help reduce the risk of denture stomatitis. Yet many denture wearers are never given comprehensive guidance on daily care routines, overnight storage, or the types of cleaning products that are most appropriate.

This article explains what denture stomatitis is, why it develops, and — most importantly — how a consistent denture hygiene routine may help you avoid it. We also discuss the signs that may indicate a need for professional dental assessment, so you can feel confident about when to seek advice from your dentist.

Whether you are new to wearing dentures or have worn them for years, this guide aims to provide practical, evidence-based information to support your ongoing oral health.

What Is Denture Stomatitis?

How do you store and clean dentures to avoid denture stomatitis?

Denture stomatitis can often be prevented by cleaning your dentures daily with a soft brush and denture cleanser, removing them overnight, and soaking them in a suitable cleaning solution. Keeping both the dentures and your mouth clean helps reduce the build-up of fungal organisms, particularly Candida albicans, which is the primary cause of denture stomatitis.

What Causes Denture Stomatitis?

Denture stomatitis is an inflammatory condition that affects the oral mucosa — the soft tissue lining of the mouth — directly beneath a denture. It is most commonly caused by an overgrowth of Candida albicans, a type of yeast that naturally exists in the mouth in small quantities.

Several factors can contribute to the development of denture stomatitis:

Poor denture hygiene — Inadequate daily cleaning allows plaque, bacteria, and fungal organisms to accumulate on the denture surface.
Wearing dentures overnight — Continuous contact between the denture and the palate creates a warm, moist environment that encourages fungal growth.
Ill-fitting dentures — Dentures that no longer fit well can cause micro-trauma to the tissue, making it more susceptible to infection.
Dry mouth — Reduced saliva flow, which may be caused by certain medications or medical conditions, can increase the risk of oral infections.
Smoking — Tobacco use may alter the oral environment and increase susceptibility to fungal colonisation.
Systemic health conditions — Conditions such as diabetes or nutritional deficiencies may affect the body's ability to manage fungal organisms effectively.

It is worth noting that denture stomatitis is not always painful, and some patients may not realise they have it until it is identified during a routine dental examination. This is one reason why regular dental check-ups remain important for denture wearers.

Recognising the Signs and Symptoms

Denture stomatitis can present in different ways, and symptoms may range from mild to more noticeable. Common signs include:

Redness beneath the denture — The tissue under the denture, particularly on the palate, may appear red or inflamed.
Soreness or discomfort — Some patients experience a burning sensation or tenderness when wearing their dentures.
Swelling of the oral tissue — The affected area may appear slightly swollen or have a velvety texture.
Small red spots — In some cases, tiny red dots may be visible on the palate.
Cracking at the corners of the mouth — Known as angular cheilitis, this can sometimes accompany denture stomatitis.

Many patients are unaware of the condition because it can develop gradually. If you notice any persistent changes to the tissue beneath your dentures, it is sensible to arrange a dental assessment. Early identification allows for appropriate management and helps prevent the condition from worsening.

The Science Behind Fungal Build-Up on Dentures

Understanding why dentures are prone to harbouring fungal organisms helps explain the importance of proper cleaning and storage.

Denture materials, particularly acrylic resin, have a slightly porous surface at a microscopic level. This porosity allows Candida albicans and other micro-organisms to adhere to and penetrate the surface of the denture, forming what is known as a biofilm. A biofilm is a thin layer of micro-organisms that bonds firmly to the denture and becomes increasingly difficult to remove if regular cleaning is not maintained.

Once a biofilm is established, it acts as a reservoir for ongoing fungal colonisation. When the denture is placed against the soft tissue of the palate, the trapped organisms come into direct contact with the oral mucosa, creating the conditions for inflammation and infection.

Saliva normally plays a protective role in the mouth by helping to wash away debris and maintain a balanced oral environment. However, when a denture covers the palate, saliva flow to that area is restricted, reducing this natural defence. This is why the tissue beneath an upper denture is more commonly affected than the tissue beneath a lower denture.

Regular removal, thorough cleaning, and overnight soaking are therefore essential to disrupt biofilm formation and reduce the concentration of fungal organisms on the denture surface.

How to Clean Your Dentures Properly

A consistent and effective cleaning routine is one of the most practical steps you can take to help prevent denture stomatitis. The following guidance reflects widely recommended best practices:

Daily Brushing

Remove your dentures and brush them at least once a day using a soft-bristled denture brush or a soft toothbrush.
Use a non-abrasive denture cleanser or mild soap. Avoid regular toothpaste, as many contain abrasive particles that can scratch the denture surface, creating additional areas where bacteria and fungi can accumulate.
Clean all surfaces thoroughly, including the fitting surface (the part that sits against your gums), the teeth, and any clasps or metal components.
Rinse the dentures well under running water after brushing.

Soaking

Soak your dentures in a denture-cleaning solution as directed by the product instructions. This helps to loosen plaque and reduce microbial build-up.
Some solutions contain ingredients specifically designed to target Candida organisms.
Always rinse your dentures thoroughly after soaking and before placing them back in your mouth.

Cleaning Your Mouth

After removing your dentures, gently brush your gums, palate, and tongue with a soft toothbrush. This helps remove residual plaque and stimulates blood flow to the tissue.
If you have any remaining natural teeth, continue to brush and floss them as recommended by your dentist.

If you are unsure which cleaning products are most suitable for your dentures, your dental team can offer personalised recommendations during your next appointment.

How to Store Your Dentures Correctly

Proper storage is just as important as cleaning when it comes to maintaining denture hygiene and supporting oral health.

Remove Dentures Overnight

One of the most important recommendations for denture wearers is to remove dentures at night. Wearing dentures continuously, including while sleeping, significantly increases the risk of denture stomatitis. Removing them allows the oral tissue to recover, breathe, and benefit from the natural cleansing properties of saliva.

Store in Water or Cleaning Solution

When not in use, dentures should be kept moist to prevent them from drying out and potentially changing shape.
Place them in clean water or a denture-soaking solution overnight.
Change the water or solution daily to maintain hygiene.
Avoid using hot water, as this can warp acrylic dentures.

Keep the Storage Container Clean

Wash your denture container regularly with soap and water to prevent it from becoming a source of contamination.
Allow it to air-dry when not in use.

Handle with Care

When cleaning or handling your dentures, do so over a folded towel or a basin of water to reduce the risk of breakage if they are dropped.

These straightforward storage habits can make a meaningful difference in reducing the conditions that allow denture stomatitis to develop.

When Professional Dental Assessment May Be Needed

While good denture hygiene is helpful, there are situations where a professional evaluation is appropriate. You may wish to consider booking a dental appointment if you experience:

Persistent redness or soreness beneath your dentures that does not improve with improved cleaning and overnight removal.
A burning sensation in your mouth or on your palate.
Cracking or soreness at the corners of your mouth.
Changes in the fit of your dentures — over time, the shape of your jawbone and gums naturally changes, which can affect how well your dentures fit.
Visible white patches or unusual changes to the oral tissue.
Difficulty eating or speaking due to discomfort or denture movement.

Your dentist can examine the health of your oral tissue, assess the condition and fit of your dentures, and recommend appropriate management if denture stomatitis or another condition is identified. In some cases, treatment may involve antifungal medication, denture adjustment, or relining or replacement of the denture to improve the fit.

It is important to remember that only a clinical examination can provide an accurate diagnosis. Symptoms that may seem related to denture stomatitis could have other causes, and a dental professional is best placed to determine the appropriate course of action.

Prevention Tips for Long-Term Denture Health

Beyond daily cleaning and proper storage, there are several additional steps that may help support your oral health and reduce the risk of denture-related complications:

Attend regular dental check-ups — Even if you no longer have natural teeth, routine dental examinations remain important. Your dentist can assess the health of your oral tissue, check the fit of your dentures, and identify any early signs of conditions such as denture stomatitis. Many dental professionals recommend check-ups at least once a year for denture wearers, though your dentist can advise on the frequency most suitable for you.
Maintain a balanced diet — Good nutrition supports the health of your oral tissue and your immune system. If you find it difficult to eat certain foods with your current dentures, discuss this with your dentist as part of your general dental care.
Stay hydrated — Drinking plenty of water helps maintain saliva production, which plays a protective role in oral health.
Avoid smoking — Smoking can alter the balance of micro-organisms in the mouth and may increase susceptibility to oral infections.
Report changes promptly — If you notice any changes to the fit of your dentures or the condition of your oral tissue, seek advice sooner rather than later. Early intervention is generally more straightforward.
Consider professional denture cleaning — Your dental team may offer professional hygiene services that can complement your home care routine.

Key Points to Remember

Denture stomatitis is a common fungal condition that develops beneath dentures, primarily caused by Candida albicans.
Daily cleaning with a soft brush and appropriate denture cleanser helps disrupt biofilm formation on the denture surface.
Removing dentures overnight allows the oral tissue to recover and reduces the warm, moist environment that promotes fungal growth.
Proper storage in water or denture-soaking solution keeps dentures moist and hygienic when not in use.
Regular dental check-ups are important for monitoring the health of your oral tissue and the fit of your dentures.
Persistent symptoms such as redness, soreness, or changes in tissue appearance should be assessed by a dental professional.

Frequently Asked Questions

Can denture stomatitis go away on its own?

In some mild cases, improving your denture hygiene routine and removing dentures overnight may help the condition to resolve. However, if the redness, soreness, or irritation persists, it is advisable to seek a professional dental assessment. Your dentist may recommend antifungal treatment or other interventions depending on the severity of the condition. Without proper management, denture stomatitis can become a recurring issue that may worsen over time. A clinical examination is the most reliable way to determine the appropriate approach.

How often should I clean my dentures?

It is generally recommended to brush your dentures at least once a day using a soft-bristled brush and a non-abrasive denture cleanser. Many dental professionals also suggest soaking dentures overnight in a suitable cleaning solution to help reduce microbial build-up. After soaking, always rinse your dentures thoroughly before placing them back in your mouth. Cleaning your gums, palate, and tongue daily is also important, as this helps remove residual plaque and supports the health of your oral tissue.

Is it safe to sleep with dentures in?

While it is physically possible to sleep with dentures in, it is generally not recommended. Wearing dentures continuously, particularly overnight, creates a warm and moist environment that promotes the growth of Candida and other micro-organisms. This significantly increases the risk of denture stomatitis. Removing your dentures at night gives the oral tissue an opportunity to rest and benefit from the natural cleansing effect of saliva. Your dentist can provide personalised advice based on your individual circumstances.

Can I use regular toothpaste to clean my dentures?

It is generally advisable to avoid regular toothpaste for denture cleaning. Many standard toothpastes contain abrasive ingredients that can create microscopic scratches on the denture surface. These scratches provide additional areas where bacteria and fungi can accumulate, making the dentures harder to keep clean. Instead, use a denture-specific cleanser or mild soap alongside a soft brush. If you are unsure which products are best suited to your dentures, your dental team can recommend appropriate options.

How do I know if my dentures fit properly?

Well-fitting dentures should feel comfortable and stable during normal activities such as eating and speaking. Signs that your dentures may no longer fit well include increased movement or looseness, sore spots, difficulty chewing, or a clicking sound when talking. Over time, changes in the shape of your jawbone and gums are natural and can affect denture fit. If you suspect your dentures are no longer fitting correctly, arranging a dental assessment is advisable, as poorly fitting dentures can contribute to tissue irritation and increase the risk of conditions such as denture stomatitis. Our guide to relining or replacing an old denture explains the options available.

Does denture stomatitis only affect upper dentures?

Denture stomatitis is most commonly associated with upper dentures because the fitting surface of an upper denture covers the palate, restricting saliva flow to the tissue beneath. This creates the enclosed, moist conditions that are particularly favourable for fungal growth. However, the condition can occasionally affect the tissue beneath lower dentures as well, particularly if hygiene routines are insufficient. Regardless of which denture you wear, maintaining a thorough cleaning and storage routine is important for reducing risk and supporting oral health.

Conclusion

Maintaining clean dentures and storing them correctly are fundamental steps in supporting your oral health and helping to prevent conditions such as denture stomatitis. By establishing a consistent daily routine — including thorough brushing, overnight soaking, and removing your dentures while you sleep — you can significantly reduce the build-up of micro-organisms that contribute to infection and irritation.

Equally important is attending regular dental check-ups, even if you no longer have natural teeth. Your dental team can monitor the health of your oral tissue, assess your denture fit, and offer guidance tailored to your specific needs. If recurring issues with denture comfort are a concern, it may also be worth exploring whether dental implants could be an alternative.

If you notice persistent redness, soreness, or any changes to the tissue beneath your dentures, seeking professional advice promptly allows for appropriate assessment and management.

Dental symptoms and treatment options should always be assessed individually during a clinical examination.
