Certain varieties of halitosis - like coffee breath, garlic breath, onion breath and morning breath - can be scrubbed at least partially away. However, one dental health expert in California recently wrote that some bad breath requires more power than a toothbrush can offer.
Doctor Guri Dhaliwal told the San Ramon Patch that while gum and toothpaste can cover some milder forms of oral odor, chronic bad breath may be caused by something that mints cannot fix - namely, tooth decay, gum disease and plaque.
The latter accumulates over time, particularly without due diligence paid to dental care. Plaque is a biofilm, or sheet of living bacteria covering a coral-like growth of tartar, which is plaque that has hardened.
Dhaliwal notes that plaque, along with post-nasal drip and dry mouth, are three common causes of chronic bad breath.
What should people with this problem do? Besides visiting a dentist at one's earliest convenience, it may be prudent to start using a specialty breath freshener, especially one that neutralizes oral odor compounds.
Additionally, individuals with chronic halitosis may be able to replace odor-causing bacteria with less harmful strains by using oral care probiotics.
