One bottle of HealThy Mouth Blend is 1/2 ounce (15ml), and contains approximately 452 drops (give or take a few drops).
One bottle generally lasts one person 2 to 3 months. That said, how long a bottle lasts is really up to you, as it’s all based on how many drops you apply per use and how many different ways you’re using it (brushing, flossing, swishing, etc.).
We’ve heard from one young family on a budget who stretched a bottle 6 months for their whole family!
