Dentures can provide a more attractive smile, better chewing ability, and greater comfort. For some, however, the odour of the mouth can be a problem after a while of wearing dentures. This may be caused by poor denture hygiene, food particles that are stuck in the denture, dry mouth, or bacterial accumulation.
If you are asking yourself, “Why Does My Mouth Smell Bad After Wearing Dentures?”, the initial thing you need to do is determine the cause. Dr. Huma Abbasi will check your mouth and dentures to see what might be contributing to the smell and what you can do to take care of it.
Why Does My Mouth Smell Bad After Wearing Dentures?
The Answer to “Why Does My Mouth Smell Bad After Wearing Dentures?” will vary from one person to another. If you don’t clean your dentures properly, they can accumulate bacteria, food particles, and plaque. These chemicals can give off bad smells.
Additional factors may be:
- Poor denture cleaning
- Food particles that accumulate between the denture and gums.
- Bacterial buildup
- Dry mouth
- Gum disease
- Oral infections
- Wearing dentures overnight
- A poorly-fitting denture
- Not cleaning the gums and tongue
If the cause is found, it may be easier to avoid a recurrence of the issue.
Poor Denture Hygiene
The most frequent cause of bad breath is improperly cleaned dentures. Dentures can trap food particles and bacteria, just as natural teeth do.
This may not be enough to clean off buildup if you rinse your dentures with water only. Denture-safe cleansers can help keep dentures fresh with regular cleaning.
You should also brush your gums, tongue, and the inside of your mouth. It is also possible for areas to contain bacteria that can cause bad breath.
Food Trapped Under Dentures
Dentures can trap food particles between the denture and gums. They will then be left sitting for a long time, and bacteria may decompose the food, causing the unpleasant smell.
Take out and clean dentures regularly. Dentures that do not fit properly might be difficult to clean beneath them, or food can get stuck.
Dry Mouth
Saliva is useful for removing food particles and bacteria. If the amount of saliva decreases, bacteria can accumulate more readily. Dry mouth may be caused by dehydration, some medications, medical conditions, or the lack of adequate water intake. Ensure sufficient intake of water throughout the day, unless told otherwise by your doctor. Talk to your dentist if you have a tendency to have dry mouth on a frequent basis.
Gum Disease and Oral Infections
A denture problem may not be the cause of bad breath, but it could be a dental problem. Persistent odors can occur with gum inflammation, oral infections, tooth decay of the remaining natural teeth, or other conditions.
If the odour persists despite clean dentures, see your dentist. It is crucial to treat the underlying issue to preserve good oral health.
Can Dentures Cause Bad Breath?
Bad odor normally isn’t due to dentures. But they can cause an odor if bacteria, plaque, and food particles build up on or under them.
An ill-fitting denture also can create areas for food and bacteria to trap. Your dentist will be able to tell if your dentures fit properly with regular check-ups.
How to Prevent Bad Breath From Dentures?
Daily good hygiene can help minimize denture odor. Here are some easy steps:
- Take out and clean dentures daily.
- Clean dentures after eating, if possible.
- Use a denture-safe cleaning product.
- Gently brush your tongue.
- Clean your gums and remaining natural teeth.
- Follow your dentist’s instructions to soak dentures.
- Store dentures in water when not in use.
- Don’t use hot water as it can alter their shape.
- Have regular dental checkups.
Avoid using abrasive denture toothpaste or harsh household cleaners on dentures unless advised by your dentist.
Should You Sleep With Dentures?
It is usually advised to remove dentures at night unless instructed otherwise by your dentist. They will provide your gums and oral tissues a respite, and you can clean the dentures thoroughly.
Spend time in the proper soaking solution or water (as recommended by your dentist). Always follow the care instructions for your particular type of denture.
