Learn how to turn your Davids Hydroxi toothpaste refill concentrate into a powerful natural mouthwash. Simple DIY steps for eco-friendly oral care.
Did you know you can transform your Davids Hydroxi toothpaste refill concentrate into a refreshing, enamel-strengthening mouthwash? This clever DIY hack not only saves money and reduces plastic waste but also gives you a custom natural mouthwash that supports your oral health between brushings. In this guide, we'll walk you through the simple steps to create your own mouthwash using the same nano-hydroxyapatite formula you love in your toothpaste.
Davids offers a range of premium natural oral care products, including their popular Davids premium toothpaste / peppermint and the innovative Davids HydroxiTM oil pulling oral rinse w/ nano hydroxyapatite / 9oz. But if you're looking for a zero-waste alternative to bottled mouthwash, the refill concentrate is your secret weapon. Let's dive into how to use it.

What You'll Need
To make your own mouthwash, you'll need a few simple items: a small glass jar or bottle (reuse an old mouthwash bottle or a small mason jar), distilled or filtered water, and a tube of Davids Hydroxi toothpaste refill concentrate. The concentrate is designed to be mixed with water to create a paste, but it works equally well as a mouthwash base. You'll also want a spoon or small whisk for stirring.
The key ingredient is nano-hydroxyapatite, a mineral that helps remineralize enamel and reduce sensitivity. By using the concentrate in a mouthwash form, you can deliver these benefits to areas your toothbrush might miss. Plus, you avoid the artificial colors, sweeteners, and alcohol found in conventional mouthwashes.
- Glass jar or bottle with a lid
- Distilled or filtered water (about 4 ounces per batch)
- Davids Hydroxi toothpaste refill concentrate (about 1 teaspoon per batch)
- Optional: a drop of peppermint essential oil for extra freshness
Step-by-Step Instructions
Start by adding 1 teaspoon of Davids Hydroxi toothpaste refill concentrate to your clean glass jar. The concentrate is thick, so use a small spatula or the back of a spoon to get it all out. Then add about 4 ounces (half a cup) of distilled or filtered water. Distilled water is best because it's free of chlorine and minerals that could affect the taste or stability of the mouthwash.
Stir or shake vigorously until the concentrate is fully dissolved. You should see a slightly milky, thin liquid. If you prefer a stronger mint flavor, add a drop of peppermint essential oil. Avoid adding too much, as the concentrate already contains natural peppermint oil. Taste test if needed, but remember this is a mouthwash, not a drink!
Transfer the mixture to a bottle with a tight-fitting lid. Shake well before each use, as the nano-hydroxyapatite particles may settle. Use about 1 tablespoon (15 ml) as a mouthwash, swishing for 30-60 seconds, then spit out. Do not swallow. Store the remaining mixture in the refrigerator for up to one week.
- Use 1 teaspoon concentrate per 4 ounces water for a standard dilution.
- Shake well before each use to redistribute the hydroxyapatite.
- Refrigerate and use within 7 days for freshness.
Benefits of DIY Mouthwash with Davids Concentrate
Making your own mouthwash from Davids Hydroxi refill concentrate offers several advantages. First, it's incredibly cost-effective. A single tube of concentrate can yield multiple batches of mouthwash, stretching your oral care budget. Second, it's eco-friendly: you reuse a glass bottle instead of buying plastic mouthwash bottles. Third, you control the ingredients—no alcohol, artificial dyes, or harsh preservatives.
The nano-hydroxyapatite in the concentrate helps remineralize enamel and can reduce tooth sensitivity over time. Combined with the natural peppermint oil, your DIY mouthwash leaves your mouth feeling clean and fresh without the burn of alcohol-based rinses. For an even more complete routine, pair it with Davids premium toothpaste / peppermint and a Davids professional tongue scraper for whole-mouth freshness.

- Saves money compared to buying bottled mouthwash.
- Reduces plastic waste—just reuse a glass bottle.
- Delivers enamel-strengthening hydroxyapatite to hard-to-reach areas.
Tips for Best Results
For optimal freshness, make small batches (4 ounces at a time) and store in the refrigerator. The mixture does not contain preservatives, so it won't last as long as commercial mouthwashes. If you notice any off smell or cloudiness, discard and make a fresh batch. Always use clean utensils and bottles to prevent contamination.
You can also customize the flavor by adding a drop of food-grade essential oils like spearmint or tea tree (use sparingly). Avoid adding sugar or honey, as they can feed bacteria. Remember, this mouthwash is a supplement to brushing and flossing, not a replacement. Use it after brushing for best results.
- Store in the fridge and use within 7 days.
- Customize with a drop of essential oil for variety.
- Use after brushing and flossing for a complete clean.
Creating your own mouthwash from Davids Hydroxi toothpaste refill concentrate is a simple, sustainable way to enhance your oral care routine. It's gentle, effective, and kind to the planet. Give it a try and experience the difference of a natural, enamel-friendly mouthwash made right at home.
