Why does your Invisalign smell bad?

There are a few reasons why your Invisalign might smell bad.

1. Poor oral hygiene

Poor oral hygiene is one of the most common causes of bad breath whether or not you are wearing Invisalign.

If you don’t brush and floss regularly, food and bacteria can build up on your teeth and Invisalign, causing the Invisalign to smell bad.

Bacteria that build up on the teeth, tongue, gums, and lips can cause bad breath. If these bacteria aren’t removed through brushing and flossing, they can produce sulfur compounds that cause bad breath.

Another thing that may be responsible for the foul smell is Invisalign attachments. These are small plastics that are attached to your teeth and you can’t remove them until the treatment is completed.

And, if you don’t clean your teeth and attachments properly, it may cause a bad smell. It will also stain the attachments.

2. Not cleaning your Invisalign properly

It’s important to clean your Invisalign trays thoroughly. If you don’t, bacteria can grow and cause your Invisalign to smell bad.

3. Wearing your aligners for too long

You should only wear your Invisalign for the prescribed amount of time. If you wear it for too long, food and bacteria can build up on your Invisalign, causing it to smell bad.

4. Bacteria build-up on aligners

If you don’t clean your Invisalign properly, bacteria can build up and cause it to smell bad. Sometimes, even after maintaining hygiene, it may happen.

5. Food particles trapped in aligners

If you don’t brush your teeth before putting on your Invisalign, food particles can get trapped in your aligners and cause them to smell bad.

6. Dental plaque

Dental plaque is a sticky film of bacteria that forms on your teeth. If you don’t brush and floss regularly, it can build up and cause your Invisalign to smell bad.

7. Tartar

Tartar is a hard deposit of calculus that forms on your teeth. It can be caused by not brushing and flossing regularly. If you have tartar, it can make your Invisalign smell bad.

8. Bad breath

If you have already bad breath, it can make your Invisalign smell bad. This is because the bacteria in your mouth that cause bad breath can also cause your Invisalign to smell bad.

9. Dry mouth

A dry mouth can cause your Invisalign to smell bad. This is because the saliva in your mouth helps to keep it clean.

When there’s not enough saliva in the mouth, bacteria can grow more easily, causing bad breath.

Moreover, less saliva can’t clean your Invisalign, and it can start to smell bad.

10. Chewing gum with aligners in

If you chew gum with your Invisalign in, the gum can get stuck in your aligners and cause them to smell bad. Moreover, it will break or damage your aligners.

11. Dental problems

Invisalign might not be responsible for the foul smell in your mouth. Dental problems such as gum disease, tooth decay, and mouth sores can also cause bad breath.

12. Infections in the nose, throat, or lungs

Infections in the nose, throat, or lungs can also lead to foul-smelling breath. These infections can produce foul-smelling mucus that can cause bad breath. This can also happen when you wear Invisalign.

13. Certain medications

Certain medications can cause dry mouth and lead to bad breath. Medications that can cause dry mouth include antihistamines, decongestants, painkillers, and diuretics.

14. Smokers and tobacco users

Smokers and tobacco users are also more likely to have bad breath. The chemicals in tobacco products can cause gum disease and tooth decay, both of which can lead to bad breath.

Moreover, smoking can cause your Invisalign to smell bad because the tobacco smoke sticks to your aligners.

15. Alcoholics

Alcoholics are also more likely to have bad breath and cause smell from the aligners. This is because alcoholics often have poor oral hygiene and dry mouth.

16. Gastroesophageal reflux disease (GERD)

Gastroesophageal reflux disease (GERD) is another condition that can lead to bad breath. So, the problem might not be with our Invisalign trays or your oral hygiene. GERD may make your Invisalign smell bad.

In this condition, stomach acid flows back up into the esophagus. This can lead to gastroesophageal reflux disorder (GERD), which can cause bad breath.

17. Liver or kidney disease

Liver or kidney disease can also be responsible for bad breath. These diseases can cause an accumulation of toxins in the body, leading to foul-smelling breath.

If you have this condition, Invisalign treatment has nothing to do with the smell.

18. Diabetes mellitus

Diabetes mellitus is a condition that can cause bad breath. Diabetics often have gum disease and dry mouth, both of which can lead to bad breath.

As adults get Invisalign to align their teeth now a day, foul smells can be a result of having Diabetes mellitus.

19. Metabolic disorders

Metabolic disorders such as phenylketonuria (PKU) can lead to bad breath.

20. Gastrointestinal problems

Gastrointestinal problems such as constipation, diarrhea, and irritable bowel syndrome (IBS) can also lead to bad breath. And, you might be mistaken for it is an Invisalign smell.

21. Other medical conditions

Some medical conditions, such as nasal polyps, ketosis, and acid reflux, can also cause bad breath.

Nasal polyps are small growths that can develop in the nose. These growths can block the flow of air and lead to bad breath.

Ketosis is a condition that can occur when the body breaks down fat for energy. This process can produce ketones, which can cause bad breath.

Acid reflux is a condition in which stomach acid flows back up into the esophagus. This can lead to heartburn and bad breath.

Food allergies can also cause bad breath because the body produces histamines in response to the allergens. These histamines can lead to inflammation and bad breath.

Inflammation such as sinusitis, bronchitis, or tonsillitis can lead to bad breath.

22. Foods with strong odors

Some foods with strong odors, such as garlic and onions, can cause bad breath.
