What kills cavities?

I recently had a toothache, and the dentist said I have a cavity. I'm curious about how cavities are treated. What actually kills the bacteria or stops the decay that causes cavities?

Oh god, cavities are the worst, I always worry if I have one! What kills them is basically a dentist, yaar. They remove the decayed part and fill it. You can't 'kill' an existing cavity at home once it's formed.

From a diet perspective, reducing sugar intake is key to *preventing* cavities, because sugar feeds the bacteria. Once you have a cavity, though, it needs professional dental care. Foods don't 'kill' existing cavities.

Bhai, simple answer: the dentist kills cavities. They clean out the bad part and put a filling. Brush twice a day and floss, that prevents them. No home remedy will make a cavity disappear.

For us diabetics, dental health is extra important because high sugar levels can worsen gum issues and cavities. No, nothing 'kills' a cavity once it's there except a dentist. Regular check-ups and controlling sugar are crucial for prevention.

Once a cavity forms, it's actual tooth decay. You cannot 'kill' it yourself. A dentist needs to remove the decayed portion and then fill the tooth to restore its structure and prevent further damage. Good oral hygiene helps prevent them, but not fix existing ones.
