New fads to improve your teeth could be having the exact opposite effect. Many dentists have warned of possible adverse reactions of following these trends and are particularly scathing about:
– Using fluoride-free toothpaste
– Drinking hot water with lemon
– Brushing teeth with charcoal toothpaste
Fluoride is essential for healthy teeth. Lemon is acidic and can erode tooth enamel. The professional consensus is to “avoid these trends if you want to look after your oral health” and a dentist should be consulted before embarking on any new dental health regimen.
