Five whitening myths, and what actually works
Charcoal, lemon and baking soda get a lot of attention. Here is what is safe and what really makes a difference.

In short
- Charcoal and lemon can wear enamel without whitening it.
- Dentist-planned whitening is safe for healthy teeth and gums.
- Crowns and fillings do not change colour, so plan around them.
Whitening is one of the most requested treatments at Scarlet, and one of the most misunderstood. These are the myths we hear most often.
1. Charcoal toothpaste whitens teeth
Charcoal can remove some surface stains, but it is abrasive and can wear enamel over time. Thinner enamel makes teeth look more yellow, not less.
2. Lemon and baking soda are a natural fix
Lemon is acidic and softens enamel. Mixed with baking soda, it scrubs that softened surface away. It is best kept out of your mouth routine.
3. Whitening damages your teeth
Professional whitening, planned by a dentist, is safe for healthy teeth. Some people feel short-lived sensitivity, which we manage with gentler gels and shorter wear times.
4. Results last forever
Whitening lasts from one to three years, depending on what you eat and drink. A top-up every so often keeps the shade you like.
5. Every tooth will change colour
Fillings, crowns and veneers do not whiten. If you have visible restorations, we plan around them so your smile stays even.
What works
Custom trays made from a scan of your teeth, with a gel strength chosen for you, give the most even and predictable result. Ask for a whitening consultation and we will show you the shade you can expect.
