Bad odor from between the teeth?


I went to two dental clinics for a cleaning and check-up because of bad odor coming from my teeth gaps.
The doctors examined my teeth and said they were in good condition.
Despite brushing normally and using dental floss, the odor from the gaps persists.
What could be the problem?

Hello Ms.
Tsai: In addition to oral hygiene issues, if there is an unpleasant odor in the mouth, it may be necessary to consider whether there are abnormal secretions from the nasopharynx or gastrointestinal tract, such as gastroesophageal reflux, which can create an acidic environment in the mouth.
If the oral examination shows no problems, it is recommended to consult a gastroenterologist or an otolaryngologist for further evaluation.

More Info


Persistent bad breath, especially when it originates from gaps between teeth, can be a frustrating and embarrassing issue. While you have already consulted two dental clinics and received reassurance about the condition of your teeth, the continued presence of bad breath suggests that there may be underlying factors contributing to this problem.


Possible Causes of Bad Breath from Gaps Between Teeth
1. Food Particles Trapped: Even with regular brushing and flossing, food particles can become trapped in the gaps between your teeth. If these particles are not completely removed, they can decompose and produce foul odors.

2. Plaque and Tartar Buildup: Plaque is a sticky film of bacteria that forms on your teeth. If not removed through proper oral hygiene, it can harden into tartar, which is much more difficult to remove. Both plaque and tartar can contribute to bad breath.

3. Gum Disease: Conditions such as gingivitis or periodontitis can lead to inflammation and infection of the gums. This can create pockets between the teeth and gums, where bacteria thrive and produce bad odors.

4. Dry Mouth: Saliva plays a crucial role in washing away food particles and bacteria. A dry mouth, which can be caused by medications, certain medical conditions, or dehydration, can lead to an increase in bad breath.

5. Sinus Issues: Sometimes, bad breath can be linked to sinus infections or post-nasal drip, where mucus drips down the back of the throat, creating an unpleasant odor.

6. Underlying Health Conditions: Certain systemic conditions, such as diabetes or gastrointestinal issues, can also manifest as bad breath.

Solutions to Address Bad Breath
1. Improved Oral Hygiene: Ensure that you are brushing your teeth at least twice a day and flossing daily. Consider using an antibacterial mouthwash to help reduce bacteria in your mouth.

2. Regular Dental Checkups: Continue to visit your dentist regularly for cleanings and checkups. If you feel that your concerns are not being addressed, don’t hesitate to seek a second opinion.

3. Use of Interdental Cleaners: In addition to dental floss, consider using interdental brushes or soft picks designed to clean between teeth more effectively.

4. Stay Hydrated: Drink plenty of water throughout the day to help keep your mouth moist and aid in washing away food particles and bacteria.

5. Chewing Sugar-Free Gum: Chewing gum can stimulate saliva production, which helps to cleanse the mouth and neutralize odors.

6. Addressing Gum Disease: If gum disease is suspected, it’s crucial to follow up with your dentist for appropriate treatment, which may include deep cleaning (scaling and root planing) or other periodontal therapies.

7. Consult a Specialist: If bad breath persists despite good oral hygiene, consider consulting an ear, nose, and throat (ENT) specialist to rule out any sinus or throat issues.

8. Dietary Considerations: Pay attention to your diet. Certain foods, such as garlic and onions, can contribute to bad breath. Additionally, a diet low in carbohydrates may help reduce the production of odor-causing bacteria.


Conclusion
Persistent bad breath can be a complex issue with multiple potential causes. While your dental health may appear satisfactory, the presence of gaps between your teeth can harbor bacteria and food particles that contribute to unpleasant odors. By enhancing your oral hygiene routine, staying hydrated, and seeking professional advice when necessary, you can effectively address this issue. If the problem continues, don’t hesitate to explore further evaluations with dental or medical professionals to uncover any underlying conditions that may be contributing to your symptoms.
