If your dentist determines that your mouth is healthy and that the odor is not oral in nature, you may be referred to your family physician or to a specialist to determine the cause of the odor and possible treatment. If the odor is due to gum disease, your dentist can either treat the disease or refer you to a periodontist, a specialist in treating gum tissues. Gum disease can cause gum tissues to pull away from the teeth and form pockets. When these pockets are deep, only a professional periodontal cleaning can remove the bacteria and plaque that accumulate.

When someone struggles with chronic bad breath, it causes emotional distress. When you are aware that you have bad breath, you are likely to struggle with confidence and avoid close conversations, exuberant laughter, and intimate encounters. People with self-consciousness regarding bad breath shy away from social interactions to spare themselves embarrassment.

While there is not scientific evidence to support an answer to the question, we believe the answer is yes. It makes sense to assume that the masks trap our exhaled air against the face, providing the opportunity to smell it. If that exhaled air contains the sulfurous gases of bad breath, we believe that our noses are more likely to detect them in that trapped environment.
