Nathan & Sons Underbrush Pearl Serum
Nathan & Sons created Pearl Serum to solve a common problem with most mouthwashes. Instead of just masking odor, this new product aims to address the root cause with a science-backed approach:
- Targets the source, not the symptom: Concentrated botanical oils like mastic, peppermint and eucalyptus help fight harmful bacteria, calm gum inflammation and freshen breath at the microbiome level.
- No burn, no fillers: Alcohol-free, fluoride-free, glycerin-free and free from synthetic flavors or preservatives—ideal for sensitive mouths and daily use.
- Ultra-concentrated and versatile: Just a few drops upgrade any toothpaste or replace mouthwash entirely, delivering clean oral care with less product and less waste.
How to use Pearl Serum
Add two to three drops to your toothbrush before brushing, dilute in water for a refreshing rinse or apply directly for targeted gum care.
One bottle lasts up to three months—a sustainable, low-waste solution for everyday oral health.
