Why Prebiotic is the Must-Have Oral Care Ingredient.

At Polished London, we're not just following trends in oral care we're setting them. From launching the world's first Hyaluronic Teeth Whitening Powder to pioneering prebiotic oral care, our mission is to combine oral health excellence with a beauty-led routine for a brighter, healthier smile.

And the ingredient at the heart of that mission? Prebiotics.

What is a prebiotic?

Prebiotics are special plant fibres typically found in fresh fruits, vegetables and whole grains that help healthy bacteria grow. In your gut, they make the digestive system work better. In your mouth, they nourish the good bacteria that keep your oral microbiome balanced and your breath fresh.

Put simply: probiotics contain bacteria, prebiotics feed them. Both matter, but prebiotics are the foundation.

Why prebiotics belong in oral care

Your mouth is home to hundreds of bacterial species. When that balance is disrupted by diet, stress, certain products or poor routine  bad bacteria can take over, contributing to bad breath, plaque build-up and gum issues.

Packing oral care products with prebiotics helps nourish the good bacteria while crowding out the bad supporting long-term oral health from within rather than just masking symptoms.

Prebiotics + Vitamin E - a powerful combination

Our prebiotic oral care formulas also contain vitamin E — an essential nutrient with antioxidant properties that protect against free radicals, which can damage cells and accelerate ageing. Vitamin E supports gum health, reduces sensitivity and helps maintain a comfortable, balanced mouth environment.

A dry mouth, oral ulcers and increased tooth sensitivity can all be signs you're lacking in vitamin E. Our prebiotic formulas help keep you topped up daily.

Polished London prebiotic products

Prebiotics run through our entire range — not as a token ingredient, but as a core part of the formula:

• Cloudberry + Mint Prebiotic Toothpaste - contains FOS (Fructooligosaccharides), a prebiotic fibre that feeds good oral bacteria with every brush. Freshens breath, supports balance and gently brightens daily.
• Peroxide-Free Hyaluronic Teeth Whitening Powder - brightens and hydrates while supporting a healthy oral environment.
• Advanced Teeth Whitening Strips - peroxide-free PAP formula designed to whiten without disrupting your oral balance.

How to build a prebiotic oral care routine

The key is consistency. Here's how to incorporate prebiotics into your daily SmileCare ritual:

1. Brush twice daily with the Cloudberry + Mint Prebiotic Toothpaste to feed good bacteria morning and night.
2. Use the Hyaluronic Whitening Powder daily for the first 14 days for visible brightening.
3. Add daily flossing to remove trapped debris between teeth and support healthier gums.
4. Stay hydrated - water supports saliva flow, your mouth's natural cleansing mechanism.
