Listen to your body. Your teeth are not a car. You can’t just keep polishing them until they shine like a diamond. Enamel is not infinite.
The golden ratio: two weeks on, three months off. That’s your new mantra. Say it before bed. Say it to your mirror.
And if you ever feel a little zing? Just stop. Take a break. Your smile will still be there, waiting. It won’t be as white, but it’ll be yours. And that’s the best kind of weird.
