Regular Dental Check-ups:

Visit your dentist for regular check-ups and cleanings.

Antibacterial Mouthwashes:

  • Mouthwashes containing antibacterial agents, such as chlorhexidine or cetylpyridinium chloride, can help reduce bacteria in the mouth. Look for alcohol-free options if you have dry mouth concerns.

Fluoride Toothpaste:

  • Using fluoride toothpaste helps prevent cavities and strengthens tooth enamel. Some toothpaste formulations also contain antibacterial agents to address bad breath.

  • Chewing sugar-free gum or sucking on sugar-free mints stimulates saliva production, which helps keep the mouth moist and washes away bacteria. Some products also contain antibacterial agents.

Saliva Substitutes:

  • For individuals with chronic dry mouth, saliva substitutes or artificial saliva products can help maintain moisture in the mouth.

Oral Probiotics:

  • Some OTC products contain oral probiotics, which are beneficial bacteria that can help balance the oral microbiome and reduce the growth of odor-causing bacteria.

Chlorine Dioxide Mouthwashes:

  • Mouthwashes with chlorine dioxide may neutralize sulfur compounds that contribute to bad breath.
