Do Dentures Cause Bad Breath?

When it comes to oral health, bad breath is a concern that affects many individuals, whether they have natural teeth or wear dentures.

Do Dentures Cause Bad Breath?

The straightforward answer is yes, dentures can be a source of bad breath. Unlike natural teeth, dentures are removable and can accumulate bacteria, plaque, and food particles if not cleaned properly. The accumulation of these elements can lead to the development of unpleasant odors, causing bad breath for denture wearers.

Maintaining good oral hygiene is crucial for everyone, but it becomes even more critical for individuals with dentures. Regular cleaning and proper care are essential to prevent the buildup of bacteria and the subsequent development of bad breath.

How Do You Get Rid of Bad Breath from Dentures?

To combat bad breath associated with dentures, a consistent and thorough oral hygiene routine is key. Here are some effective ways to maintain fresh breath while wearing dentures:

1. Brush Your Dentures Daily:

Just like natural teeth, dentures need to be brushed daily to remove bacteria and plaque. Use a soft-bristle brush specifically designed for dentures to avoid damaging the prosthetic.

2. Soak Dentures Overnight:

Soaking dentures in a denture-cleaning solution or a mixture of water and vinegar overnight helps to eliminate bacteria and odors. This routine can be particularly beneficial in preventing bad breath.

3. Clean Your Mouth and Gums:

Even if you don’t have natural teeth, maintaining oral hygiene is crucial. Gently brush your gums, tongue, and the roof of your mouth with a soft toothbrush to remove bacteria and stimulate blood circulation.

4. Stay Hydrated:

Adequate hydration is essential for combating dry mouth, which can contribute to bad breath. Drink plenty of water throughout the day to keep your mouth moist and minimize the growth of odor-causing bacteria.

5. Regular Dental Check-ups:

Schedule regular dental check-ups to ensure that your dentures are fitting properly and to address any potential issues early on. Your dentist can provide guidance on maintaining optimal oral health with dentures.

How Do You Deodorize Dentures?

Ensuring that your dentures smell fresh is an integral part of maintaining good oral hygiene. Here are some tips to deodorize your dentures:

1. Use Denture Cleaners:

Denture-cleaning tablets or solutions are designed to eliminate bacteria and odors. Follow the instructions on the product to ensure effective cleaning.

2. Baking Soda Soak:

Soaking dentures in a mixture of water and baking soda can help neutralize odors. This natural deodorizing agent is gentle on dentures and effective in combating unpleasant smells.

3. Avoid Harsh Chemicals:

While cleaning is essential, avoid using harsh chemicals, bleach, or abrasive cleaners, as they can damage the denture material and lead to more problems.

Can Denture Adhesive Give You Bad Breath?

Denture adhesives, commonly used to improve the fit and stability of dentures, may contribute to bad breath if not used correctly. Excessive use of denture adhesive or failure to clean it thoroughly can lead to bacterial buildup, causing an unpleasant odor. It’s crucial to follow the manufacturer’s instructions for denture adhesive application and removal and to clean both the dentures and the adhesive thoroughly.

Why Do New Dentures Smell?

New dentures may emit a peculiar smell, often described as a chemical or plastic odor. This smell is typically a result of the materials used in the manufacturing process. Proper cleaning and soaking in a denture-cleaning solution can help eliminate this initial odor. If the smell persists, consult your dentist to ensure that there are no issues with the fit or material of the dentures.

Does a Bad Smell from Dentures Cause a Bad Taste When You Wear Them?

Yes, bad breath from dentures can be accompanied by a bad taste. The accumulation of bacteria and food particles on dentures can affect the taste in your mouth. Maintaining proper oral hygiene, including regular cleaning of both the dentures and the mouth, is essential to prevent an unpleasant taste while wearing dentures.


In conclusion, while dentures can contribute to bad breath, proactive and consistent oral hygiene practices can mitigate this issue. Regular cleaning of dentures, proper care of the mouth and gums, and routine dental check-ups are crucial for maintaining fresh breath and overall oral health. If you experience persistent issues with bad breath or any concerns related to your dentures, it’s advisable to consult with your dentist.
