Why Do My Dentures Have A Fishy Smell? Solutions

If you’re experiencing a persistent fishy smell coming from your dentures, you’re not alone. This unpleasant odor is a common concern for denture wearers and can significantly impact confidence and social interactions. The primary reasons for this bad odor dentures are the buildup of bacteria and fungi on the denture surfaces, combined with trapped food particles and saliva. Addressing this issue requires a diligent approach to denture cleaning and proper denture hygiene.

Fathoming the Foul Smell: Common Causes

The development of a foul smell dentures is usually linked to a few key culprits:

• Bacterial and Fungal Growth: Our mouths are naturally home to a variety of microorganisms, including bacteria and fungi like Candida albicans (which causes thrush). Dentures, with their porous surfaces and intricate designs, provide an ideal environment for these microbes to thrive. When left uncleaned, they multiply, producing waste products that lead to a distinct and unpleasant odor. This denture bacteria accumulation is the leading cause of that characteristic fishy smell.

• Trapped Food Particles: Even with meticulous brushing, tiny food particles can become lodged in the nooks and crannies of dentures. These particles, when combined with saliva and the warm, moist environment of the mouth, begin to break down. This decomposition process releases volatile sulfur compounds (VSCs), which are notorious for their foul, often fishy, smell.

• Saliva and Mucus Accumulation: Saliva plays a vital role in oral health, but it also contains proteins and other organic matter. When dentures aren’t cleaned regularly, this organic matter can accumulate and become a breeding ground for bacteria, contributing to the mouth odor dentures and the overall bad breath dentures problem. Mucus, especially if you have a tendency to produce more, can also contribute to this buildup.

• Improper Denture Fit: While less common as a primary cause of odor, an ill-fitting denture can create areas where food and bacteria are more easily trapped. This can exacerbate the problem, leading to increased foul smell dentures.

• Underlying Medical Conditions: In some cases, a persistent fishy smell that doesn’t improve with diligent cleaning might be a sign of an underlying medical issue. These can include sinus infections, respiratory tract infections, or even certain metabolic disorders that affect breath odor. If you suspect this, it’s essential to consult your dentist or doctor.

Deciphering the Denture Odor: Key Factors at Play

Several factors contribute to the development and persistence of that unwelcome fishy smell on your dentures:

• Porous Materials: Denture bases, often made from acrylic resin, are not entirely non-porous. Over time, microscopic pores can develop, allowing bacteria and staining agents to penetrate the material. This makes them harder to clean completely.

• Surface Irregularities: The way dentures are manufactured means they have very small ridges and contours. While almost invisible to the naked eye, these areas can harbor bacteria and food debris, making thorough cleaning a challenge.

• Lack of Regular Cleaning: This is, by far, the most significant contributor. If dentures are not removed and cleaned daily, the biofilm of bacteria and food debris will continue to grow, leading to odor.

• Dietary Habits: Certain foods, particularly those with strong odors like garlic, onions, and fish, can leave residual smells on dentures. While this is often temporary, a buildup of these residues can contribute to a more persistent odor if not cleaned properly.

• Dry Mouth (Xerostomia): Saliva helps to wash away food particles and neutralize acids produced by bacteria. If you experience dry mouth, the risk of bacterial overgrowth and associated odors increases. This can worsen mouth odor dentures.

Tackling the Odor: Effective Denture Cleaning and Hygiene

The good news is that with consistent and proper denture cleaning, you can effectively eliminate and prevent that fishy smell. Here are essential practices:

Daily Cleaning Rituals

• Remove and Rinse: Always remove your dentures before sleeping. Rinse them under cool or lukewarm running water to remove loose food particles. Never use hot water, as it can warp the denture material.

• Gentle Brushing: Use a soft-bristled denture brush or a soft toothbrush. Specialized denture brushes are designed to reach all surfaces without causing damage. Use a non-abrasive toothpaste or a mild hand soap. Avoid regular toothpaste, as it can be too abrasive and damage the denture surface. Brush all surfaces of the dentures thoroughly, paying attention to any clasps or attachments. This step is crucial for removing plaque and food debris, tackling bad breath dentures.

• Soaking: After brushing, soak your dentures in a denture-cleansing solution. Follow the manufacturer’s instructions for the soaking time. Denture cleansers are formulated to kill bacteria and fungi that cause odors. Ensure the soaking solution completely covers the dentures.

• Rinse Again: Before reinserting your dentures, rinse them thoroughly with water to remove any residue from the cleansing solution.

Weekly Deep Cleaning and Maintenance

• Soaking with Specialized Cleaners: Beyond daily soaking, consider using a more potent denture-cleansing solution or effervescent tablets once a week. These can help break down tougher stains and further combat denture bacteria.

• Inspect for Damage: While cleaning, take a moment to inspect your dentures for any cracks, chips, or rough spots. These imperfections can harbor bacteria and make cleaning more difficult. Report any damage to your dentist.

Oral Hygiene for Denture Wearers

• Brush Your Gums and Tongue: Even with dentures, it’s vital to maintain good oral hygiene for your remaining natural teeth, gums, and tongue. Brush your gums, tongue, and the roof of your mouth with a soft toothbrush or a damp washcloth. This helps remove plaque and bacteria that can contribute to bad odor dentures.

• Saliva Stimulation: If you suffer from dry mouth, talk to your dentist about ways to stimulate saliva production. This might include drinking plenty of water, chewing sugar-free gum, or using saliva substitutes.

Denture Odor Remedies: What Works and What Doesn’t

Several products and methods can help combat that fishy smell. It’s important to choose wisely:

What to Avoid: Denture Cleaning Pitfalls

• Abrasive Cleaners: As mentioned, regular toothpaste, harsh scouring powders, or abrasive brushes can scratch and roughen your dentures. These microscopic scratches create more surface area for bacteria to colonize, worsening the bad odor dentures and leading to mouth odor dentures.
• Boiling Water: Never boil your dentures. This can warp the acrylic, causing them to fit poorly and potentially become uncomfortable or even damaging to your oral tissues.
• Bleach: While bleach kills bacteria, it can also damage the denture material, causing discoloration and weakening the prosthesis. It’s also not safe for oral use if residual amounts remain.

When to Seek Professional Help

If you’ve been diligently following a rigorous denture cleaning routine and still experience a persistent fishy smell, it’s time to consult your dentist. They can help identify:

• Hidden Denture Damage: Micro-cracks or wear on the denture surface that are invisible to you could be accumulating bacteria.
• Underlying Oral Health Issues: Conditions like oral thrush (a fungal infection), gum disease, or even sinus infections can contribute to persistent bad breath, which may manifest as a fishy smell from your dentures.
• Denture Relines or Replacements: Over time, dentures can wear down or the fit can change due to bone resorption in your jaw. Poorly fitting dentures can trap more food and bacteria, leading to odor. Your dentist can assess if a reline or new set of dentures is necessary.
