Why does sugar hurt cavities?

I have a few cavities, and whenever I eat something sweet like jalebi, it really stings! My dentist said to avoid sugar, but I don't get why it hurts so much specifically when I eat sweets. Can anyone explain?

Oh, it's like a party for the bad bacteria in your mouth! 🎉 They LOVE sugar and when they eat it, they produce acid. This acid then attacks your tooth enamel, making cavities worse and causing that ouchie feeling! So brush brush brush! 🦷

Haan na, ye bahut common hai. Jab hum sugar khaate hain na, toh muh ke bacteria usko kha kar acid banate hain. Cavity mein toh already daant ka protective layer gaya hota hai, toh vo acid seedha nerve tak pahunchta hai aur dard hota hai. Bas yehi story hai.

Sugar doesn't hurt cavities directly. It fuels the oral bacteria that produce acid. This acid then demineralizes the tooth structure, worsening the cavity and exposing the sensitive dentin and pulp. That's what causes the sharp pain. Regular dental check-ups are essential.

I know how awful that pain is! It's because the sugar acts like fuel for the bacteria in your mouth, which then create more acid. This acid irritates the sensitive parts of your tooth that are already exposed by the cavity. Warm salt water rinses can sometimes help dull the pain a little, but a dentist is the only real fix.

Been there, felt that pain! The problem is not sugar directly, but what sugar does. It feeds the bacteria in your mouth that produce acids. These acids then further erode the already damaged tooth, reaching the sensitive nerve. So, less sugar, more brushing, and see a dentist ASAP for cavities.
