*Updated May 2026: Following my move from Google Blogger to this new WordPress site, I’ve updated this review with 2026 Australian pricing and my final recommendation for a natural, SLS-free fluoride toothpaste.
The Hunt for SLS-Free Oral Care: Why I Chose Grants of Australia
I was specifically searching for a toothpaste without SLS (Sodium Lauryl Sulfate). SLS is a common surfactant used in many personal care and household products, such as shampoos, toothpastes, hair conditioners, and laundry detergents, because it creates bubbles and improves cleaning power.
However, SLS has been controversial due to potential irritation to the skin, scalp, and eyes, and some studies suggest it may affect the hormonal system over time. This toothpaste replaces SLS with a plant-based surfactant called Sodium Lauroyl Sarcosinate, derived from coconut. It’s considered safe, though it can occasionally irritate very sensitive individuals. Other than this, the formula is free from controversial ingredients.
The Great Fluoride Debate: My Stance and Finding the Right Balance
My husband and I have tried several SLS-free toothpastes, and this one has become his favourite, so we’ve been using it regularly.
That said, I’m still on the lookout for an SLS-free fluoride toothpaste, which is surprisingly hard to find. I personally believe that fluoride, in the proper amounts, is effective for preventing cavities, even though there are ongoing debates about its safety.
Some toothpaste brands offer hydroxyapatite-based formulas as a fluoride alternative. These are promising for tooth remineralisation and cavity prevention, but unfortunately, they tend to be more expensive.
🦷 My Current Go-To Toothpaste: After much searching, I have finally settled on Red Seal – Complete Care. It perfectly meets my criteria as it is both SLS-free and contains fluoride. If you are curious about why I switched and want to see a detailed breakdown of this product, check out my full review here:

Quick Comparison: Grants vs. Red Seal
| Feature | Grants (Mild Mint) | Red Seal (Complete Care) |
|---|---|---|
| SLS-Free | Yes ✅ | Yes ✅ |
| Fluoride | No 🚫 | Yes 🦷 |
| Freshness | Subtle/Mild | Moderate to Strong ✨ |
| Price Point | Affordable 💰 | Affordable 💰 |
The picture shows that the consistency is more liquid-like and soft instead of being a firm paste. Because of this, using a dry toothbrush helps maintain the consistency longer.
Affordable Natural Care: Is Grants of Australia Worth the Price?
In terms of price, this toothpaste is moderately priced compared to other brands in the 90g–110g range, making it a reasonable option for those seeking SLS-free oral care without breaking the bank.
🛒 Shopping Tip in Australia: As of May 2026, the original price is approximately $4.50 AUD, and it is available for purchase at Coles and Woolworths. Since they often run promotions on toothpaste, I recommend keeping an eye on their weekly catalogues and stocking up when they are on sale. Additionally, while the standard size is 110g, a 25g travel size is also available at various online shops for around $2.50 (RRP)—perfect for testing the product or for your next trip.
The Science of a Healthy Smile: Testing the pH Balance
A slightly alkaline toothpaste is considered ideal because it helps neutralise acids in the mouth, which are a primary cause of cavities. Based on my pH test, this toothpaste appears to have a near-neutral pH of 7–8, which is good for maintaining oral balance without being too harsh.

💡 Tip: A small lesson from my pH testing: because the toothpaste is so thick and opaque, putting it straight onto the strip can hide the actual colour change. If you’re trying this at home, I’d suggest mixing a bit of toothpaste with distilled water first for a much clearer result. Even with the thick paste covering the strip, I could see it leaning towards a healthy, neutral-to-alkaline pH of 7–8.
The Honest Verdict: What I Loved and What I Didn’t
Pros:
- The mint flavor is subtle, so brushing feels gentle without any spicy or overwhelming sensation.
- Leaves a mildly fresh feeling after brushing, suitable for sensitive mouths.
- Free from SLS and other controversial ingredients, making it a safer, plant-based option.
Cons:
- Freshness doesn’t last as long compared to conventional SLS-containing toothpastes.
- The texture becomes watery quickly, making it slightly difficult to brush for the recommended 3 minutes. (Tip: Use a dry toothbrush!)
⚠️ Note on Whitening Version: From the same brand, we’ve also tried a baking soda toothpaste aimed at whitening. While it performed adequately, it left a white film inside the mouth even after thorough rinsing. It might be due to the alkaline particles reacting with the oral mucosa, so I’d suggest rinsing extra thoroughly if you choose that specific line.
Who Should Buy This? 🎯
- Recommended for: People with sensitive gums, those avoiding all synthetic chemicals, or budget-conscious natural product seekers.
- Not recommended for: People who crave a strong menthol ‘kick’ or those who need long-lasting breath freshness for long workdays.
Final Thoughts: A Gentle, Eco-Friendly Choice
Overall, this SLS-free toothpaste is a gentle and reasonably priced choice, especially for those concerned about sensitive teeth or gums. While it doesn’t provide the long-lasting freshness of traditional SLS toothpastes, it offers a safe, plant-based alternative for daily use. If you’re looking for fluoride-free, gentle, and eco-friendly oral care, it’s worth giving this one a try.
