Chlorhexidine, Listerine, ioRinse, and every prescription rinse on the market are water-based. The bacteria driving your gum disease build a hydrophobic (water-repellent) biofilm shield around themselves at 6-9mm depth, so water-based antimicrobials physically bead up on the surface and roll off without ever reaching the infection. Opaline is lipid-soluble, meaning it merges with the oily biofilm instead of bouncing off it, and it's delivered through the bloodstream rather than swished on the surface, so it reaches the bacteria from the inside out.

Most users notice reduced bleeding within 14 days and a cleaner taste in the mouth within the first week. Measurable pocket depth reduction typically shows up at the 6 to 8 week mark when your hygienist re-probes. In the published Leuven trial, 71% of participants saw measurable pocket reduction within 6 months, and bleeding on probing decreased by an average of 62%.

Yes, and you should. Opaline is designed to work alongside your existing oral hygiene routine, not replace it. Brushing, flossing, and professional cleanings handle the surface plaque and supragingival bacteria. Opaline targets the deep-pocket biofilm those tools physically cannot reach.

Opaline uses food-grade wild Mediterranean oregano oil and cold-pressed black seed oil, both with long histories of safe human consumption. Some users notice mild oregano aftertaste in the first few days. If you take blood thinners, blood pressure medication, or diabetes medication, or if you're pregnant or nursing, check with your physician before starting any new supplement.

Oregano and black seed oil are powerful natural compounds that can lower blood sugar and thin the blood. If you are taking blood thinners (like Warfarin), diabetes medication, or any prescription drug, please speak with your doctor before starting. We want you safe, not just healed.

Every bottle of Opaline is backed by a 60-day money-back guarantee. Use every capsule, get re-probed by your hygienist, and if you don't see measurable improvement in bleeding, breath, or pocket depth, send back the empty bottle for a full refund. You're only out the time it took to find out.
