If you have chronic bad breath and wear dentures, it’s not necessarily what you’re eating that’s causing it. It could be your prosthesis itself that’s developed an unpleasant odor. It’s more common than you may think, and a few simple changes to your daily routine can help keep your dentures smelling fresh and feeling comfortable!
What Causes Dentures to Smell Bad?
Several factors can contribute to unpleasant denture odors.
Bacteria and Plaque Buildup
Even though dentures are artificial, they can accumulate plaque, bacteria, and food particles. If these substances are not removed regularly, they can produce unpleasant smells. Bacteria can also accumulate on your tongue, gums, and any remaining natural teeth, contributing to bad breath.
Inadequate Cleaning
Rinsing dentures with water alone usually isn’t enough to remove all the debris and microorganisms that collect on their surfaces. Skipping daily cleaning or failing to clean hard-to-reach areas can allow odor-causing buildup to develop.
Wearing Dentures Overnight
Wearing dentures continuously, including while sleeping, can contribute to irritation and increase the risk of oral infections. Removing them at night gives your oral tissues a chance to rest and makes thorough cleaning easier.
Dry Mouth
Saliva helps wash away food particles and bacteria. When your mouth is dry, odor-causing bacteria may accumulate more easily. Certain medications and health conditions can contribute to dry mouth, which may affect denture wearers.
Poorly Fitting Dentures or Oral Infections
Dentures that no longer fit properly can trap food and irritate your gums. In some cases, persistent odors may be associated with oral infections, including denture-related stomatitis, which causes inflammation beneath the appliance.
How to Keep Your Dentures Clean and Odor-Free
Maintaining a consistent cleaning routine is one of the best ways to prevent unpleasant denture odors.
- Clean your dentures daily: Remove and rinse them after meals when possible. Brush them gently with a soft denture brush and a denture-specific cleanser. Avoid regular abrasive toothpaste, which can scratch the material.
- Soak them overnight: Unless your dentist advises otherwise, remove your dentures before bed and place them in water or an appropriate denture-soaking solution according to the manufacturer’s instructions. Never let them dry out.
- Clean your mouth, too: Brush your remaining natural teeth, clean your tongue, and gently brush your gums and the roof of your mouth.
- Hydrate: Drinking water throughout the day can help relieve dry mouth and support oral comfort.
- See your dentist regularly: Your dentist can check the fit of your dentures, assess your oral tissues, and recommend adjustments or professional cleaning when needed.
If your dentures continue to smell despite proper cleaning, or you notice sore spots, redness, swelling, or unyielding bad breath, schedule a dental appointment. These symptoms may indicate an underlying problem that requires treatment.
