ozone application reverses leathery root cavities to hard tissue in 100% of cases over 18 months
A double-blind, randomised, controlled 18-month clinical trial demonstrated that 40-second ozone treatment of leathery root caries lesions resulted in 100% reversal to hard lesions (87/87), compared to only 1/87 in the placebo group.
What this means for you
Root surface cavities that feel soft and leathery are actively breaking down tooth structure — but this finding shows ozone exposure can stop and reverse that process entirely. In a rigorous 18-month trial, every single treated lesion hardened back up. That kind of reversal supports long-term dental resilience without invasive intervention.
