Just like natural teeth, dentures can be prone to bad smells. With the proper care, however, you can help prevent unpleasant denture smells. Proper denture hygiene is the best way to keep your dentures and breath smelling fresh.

What Causes Denture Smells?

Our mouths are the perfect home for bacteria, and dentures can create even more spaces for bacteria to grow. When you eat, particles of food can become trapped under and around your dentures. These food particles can cause unpleasant smells on their own, but also create the ideal environment for bacteria.

Bacteria feed on the leftover food particles and then multiply. The more bacteria, the worse your dentures will smell. The good news is, regular cleaning of your mouth and dentures can help eliminate these bacteria and alleviate “denture breath”.

How to Prevent Denture Smells

These denture care and hygiene techniques will help prevent denture smells.

Use Denture Adhesive

Denture adhesive helps your dentures fit closely to your gum line and prevents them from moving while you eat. When your dentures securely adhere to your gums, it’s less likely food will become trapped there. Less food trapped in your dentures will help to prevent bacteria growth and unpleasant smells.

Soak Your Dentures Overnight

You should remove your dentures every night, not only to give your mouth a break, but to prevent bacteria from accumulating while you sleep.

After removing your dentures, place them in a denture solution or cleanser. Water can also work in a pinch, but a denture solution will help to remove more of the odour-causing bacteria. 

Brush Your Dentures Regularly

For the best smelling dentures, you should try and brush your dentures after every meal. If that isn’t an option, try to at least rinse your dentures under running water after eating to remove food particles.

Also, make sure you’re brushing your dentures after soaking them overnight. Use a soft-bristled denture toothbrush to brush all sides of your dentures. Don’t use toothpaste as this can damage your dentures. When you’re done brushing, rinse your dentures under running water to remove any remaining denture solution.

Maintain Oral Hygiene

You need to make sure you’re cleaning your mouth, as well as your dentures, to prevent denture smells. After removing your dentures, use a soft-bristled toothbrush to brush your gums and any implants or remaining teeth you have. Don’t forget to brush your tongue too, as this can be a source of bad breath. 

Visit Your Denturist Regularly

If you’re having trouble keeping your dentures smelling fresh, a denturist can help determine the cause of the problem. They can deep clean your dentures for you and check for (and repair) broken dentures. Bacteria can hide in the cracks and crevices of broken dentures, causing unpleasant smells. 

You should be able to wear your dentures with confidence. If denture smells or other issues are affecting your ability to wear your dentures, schedule an appointment at one of our denture clinics. We can get to the bottom of what’s causing your denture issues and recommend a solution.
