If you decide what to read on the basis of whether or not it has a catchy title, you likely missed “The Efficacy of Different Mouthrinse Formulation in Reducing Oral Malodour: A Randomized Trial” in the Journal of Clinical Periodontology (presuming, of course, you’re the type who reads things like the Journal of Clinical Periodontology).
Are you interested now?
The randomized, double-blind trial was small and simple: For one week, 18 participants used one of three rinses. Two products – Halita and Meridol with zinc lactate – contained at least one antimicrobial agent (Halita contains cetylpyridinium chloride and chlorhexidine in addition to the zinc). The other contained fluoride.
Sulfur levels and organoleptic (“sniff test”) scores were taken twice to measure odor – once 15 minutes after their first rinse and again at the end of the week. The first took note of masking effects, while the second noted therapeutic effects.
Those were the rules, but how did it turn out?
All three rinses did fine with respect to immediate freshness, but only those with antimicrobials showed a therapeutic effect. They also had the most powerful masking effect.
Does this mean chemical clean is the way to go?
All have their downsides. Chlorhexidine and cetylpyridinium chloride tend to stain the teeth. The latter may also irritate the soft tissues of the mouth or trigger allergic reactions. Fluoride, of course, has its own problems.
And none have proven much better than more natural products, which raises the issue we’ve noted before:
If the effects of natural substances on oral [pathogens] are at least as good as those of a chemical substance, why opt for the chemical?
One alternative we especially like is Natural Dentist Healthy Gums Mouth Rinse. This natural mouthwash helps control periodontal disease and biofilm (plaque) build-up through its blend of cleansing and soothing botanicals including echinacea, golden seal, grapefruit seed, aloe vera gel and calendula. It contains no alcohol, artificial sweeteners, dyes or preservatives, and will not stain the teeth.
