Why Do Our Teeth Feel Strange After Eating Spinach? | RapidSmartFacts

That weird “ chalky” or squeaky feeling on your teeth after spinach isn’t your imagination.

It’s a tiny chemistry moment happening on your enamel. Spinach contains compounds called oxalates.

Oxalates can bind with calcium in your saliva. This can form a light,

temporary film on the surface of your teeth. That film changes friction,

making your teeth feel squeaky or gritty. Some people notice it more depending

on saliva flow and oral chemistry. It’s not usually harmful. The effect often

fades as you drink water. And your saliva clears the surface. Eating other foods

can also help “ reset” the feeling. So this is a sensation change, not your teeth
