TheraBreath toothpaste: what the oxygenating formula does
TheraBreath’s oxygenating claim comes down to one inactive ingredient: sodium chlorite, branded as OXYD-8. It generates oxidizing power on contact with saliva, and TheraBreath’s own product page describes it as an oxygenating compound that fights the anaerobic bacteria behind bad breath. Fluoride in the same tube handles cavity protection separately. This is general information, not dental advice.
What the chlorite actually does
Sodium chlorite is not an abrasive or a foaming agent. It sits in the inactive ingredient list of TheraBreath Fresh Breath Toothpaste (Mild Mint) alongside sorbitol, hydrated silica, and glycerin, per the label TheraBreath publishes on its own site. The active ingredient doing the cavity work is Sodium Fluoride at 0.24 percent.

Bad breath bacteria are mostly anaerobic, meaning they thrive without oxygen. TheraBreath states the chlorite’s oxidizing action disrupts that environment, on top of whatever brushing removes mechanically.

Not every tube in the lineup carries it
TheraBreath sells more than one toothpaste line, and they are not identical. The Deep Clean Toothpaste swaps in Stannous Fluoride at 0.454 percent and lists sodium lauryl sulfate in its inactive ingredients, per its own label. That formula skips OXYD-8 entirely.
If SLS sent you looking for alternatives in the first place, that distinction matters. The original Fresh Breath Mild Mint formula has no sodium lauryl sulfate. For more brands built the same way, see our SLS-free toothpaste guide.
Oxygenating paste versus a standard cavity paste
| Product | Active ingredient | Oxygenating agent | Contains SLS | Street price, per source |
|---|---|---|---|---|
| TheraBreath Fresh Breath Toothpaste, Mild Mint | Sodium Fluoride 0.24% | Sodium Chlorite (OXYD-8) | No | $10.99 per 4oz tube, therabreath.com |
| Crest Cavity Protection Regular | Sodium Fluoride 0.243% | None listed | Yes | Around $2 per tube, Walmart listing |
Where this fits next to what you already use
OXYD-8 solves an odor problem, not a remineralization one. If your priority is rebuilding enamel rather than neutralizing odor-causing bacteria, hydroxyapatite works through a different mechanism, covered in our hydroxyapatite toothpaste guide.
TheraBreath also sells a separate Healthy Gums line aimed at bleeding and inflamed gums, which this page does not cover. If that is your main issue, our toothpaste for bleeding gums roundup covers dedicated options side by side.
Fluoride or not, and how to pick
Fresh Breath Toothpaste is sold both with and without fluoride, per TheraBreath’s own product description, so you can keep the OXYD-8 mechanism while opting out of fluoride if that is a personal preference. A single 4oz tube runs $10.99 direct from therabreath.com at the time of writing.
