Social media has introduced a wave of oral health trends that range from mildly useful to genuinely damaging. As a clinical team, we get asked about these regularly. Here's our honest, evidence-based assessment — no agenda, no product to sell.
Oil pulling
Oil pulling — swishing coconut or sesame oil around the mouth for ten to twenty minutes — has some limited evidence behind it for reducing certain oral bacteria. It won't replace brushing or flossing, and the mechanism is mechanical rather than chemical. If you enjoy it as an add-on to your routine, it's unlikely to cause harm. Just don't skip the floss because you pulled.
Charcoal toothpaste
Activated charcoal is abrasive. Regular use wears enamel — the substance that protects your teeth and, once gone, cannot be restored. We do not recommend charcoal toothpaste to our patients.
The whitening effect is superficial and temporary. The enamel loss is not. This is one trend worth skipping entirely.
Hydrogen peroxide rinses
Used correctly and at appropriate concentrations, hydrogen peroxide rinses have legitimate whitening and antimicrobial applications. The key words are correctly and appropriate concentrations. DIY high-concentration peroxide use can cause chemical burns, gum damage, and sensitivity. If you're interested in peroxide-based whitening, do it under clinical supervision.
What about fluoride?
Fluoride remains the gold standard in cavity prevention, despite persistent online claims to the contrary. The evidence base is extensive, long-standing, and unambiguous. If you've read something online and you're unsure, ask us at your next visit. We'd rather answer a question than repair the consequences.
