You have switched to charcoal toothpaste. Your teeth feel cleaner, brighter, and smoother after every brush. It seems like a smart, natural choice — activated charcoal is all over social media, after all. But is rubbing abrasive charcoal on your teeth every single day actually a good idea? The short answer is no. Here is why.

Charcoal is too abrasive for daily use

Activated charcoal is a highly abrasive substance. It is what makes it effective at scrubbing away surface stains. The problem is that your teeth have a protective outer layer called enamel. Enamel is not renewable. Once it is gone, it is gone. Using an abrasive substance on your teeth twice a day, every day, gradually wears that enamel down. This process is slow — so slow you may not notice it happening until your teeth become sensitive or you develop cavities more easily than before.
Thinning enamel creates real problems

As enamel thins, the dentine underneath — which is naturally yellow and softer — starts to show through. Your teeth may look more yellow, not less. You may start experiencing sensitivity to hot, cold, sweet, or acidic foods and drinks. And because dentine is softer than enamel, your teeth become more susceptible to cavities. The very thing you are doing to make your teeth look better could, over time, make them weaker and more stained.
Most charcoal toothpastes do not contain fluoride

Fluoride is the most clinically proven ingredient in toothpaste for strengthening enamel and preventing decay. Most charcoal toothpastes do not contain it — either because the charcoal absorbs the fluoride or because it is simply not included in the formula. Using a non-fluoridated toothpaste daily means you are missing the key ingredient that protects your teeth from cavities. That is a significant trade-off for the sake of a deeper clean feeling.
Charcoal can stain your dental work and gums

Charcoal particles can get trapped in the edges of crowns, veneers, and fillings, causing them to look discoloured over time. It can also temporarily darken your gums if it settles into gum pockets. If you have any dental restorations, charcoal toothpaste is particularly risky for the appearance of your smile.
What to use instead

You do not need charcoal to keep your teeth clean and white. A regular fluoride toothpaste, used twice a day, does everything you need. If you want to address staining, talk to your dentist about safe whitening options. There are over-the-counter products with the ADA Seal of Acceptance that are tested for safety, and professional whitening treatments that are both effective and enamel-safe. Your dentist can also advise whether charcoal toothpaste is ever appropriate for your specific teeth — and for most people, the answer is only occasionally at most.
Your enamel is irreplaceable — treat it that way

The trend for charcoal toothpaste is understandable — the clean, polished feeling after brushing is satisfying. But that satisfying feeling is the abrasive particles doing their job a little too well. If you have been using charcoal toothpaste daily, bring it up at your next dental appointment. We can assess whether your enamel has been affected and recommend a toothpaste that is right for your teeth long-term. Call 01323 723757 or book at www.meadsdental.com Meads Village Dental Practice
