PLACERVILLE, Calif., Nov. 11, 2025 — CymaTones?, a California wellness-technology start-up, on Tuesday unveiled the CymaSonic? Frequency Toothbrush, a patent-pending device that combines bone-conduction delivery and curated harmonic frequencies to target gum and enamel health.
The company says the toothbrush channels subtle sound vibrations through the jawbone to stimulate microcirculation, strengthen enamel and “align the mouth’s natural bioelectric balance.” Since a limited pre-launch, CymaTones reports more than 1,000 units sold worldwide.
Each CymaSonic model contains a single embedded sound chip drawn from CymaTones’ library of 634 frequency sets. The company markets the harmonics as tuned for three focus areas: teeth (enamel support), gums (soft-tissue circulation) and roots (bone and jaw vitality). Users quoted in the company release described reduced gum pain, less tooth sensitivity and an overall soothing sensation.
The brush is rechargeable, water-resistant and designed for travel. CymaTones also offers replaceable heads with bamboo handles and castor-oil-based bristles, which the company says improve sound transfer while reducing environmental impact.
“We’ve always believed that sound can do more than entertain—it can heal,” said Bianca Ruehlig, founder and CEO of CymaTones. “By merging bone-conduction physics with harmonic frequencies, we created a toothbrush that doesn’t just polish teeth; it helps the mouth remember its natural rhythm of health.”
Dental experts were not cited in the company statement. CymaTones frames the product as a wellness innovation that augments—but does not replace—traditional oral care practices.
The CymaSonic is available directly from CymaTones; pricing and wider retail plans were not disclosed in the announcement.
