What are cavities made of?

My dentist told me I need a filling for my cavity. I was just wondering what these fillings are actually made of. What are cavities (the fillings) typically made of?

Cavities aren't actually made of anything solid, they are just empty spaces or holes in your teeth. They happen when the hard outer layer of the tooth decays over time.

They are holes made by decay, filled with bacteria and food debris. I ignored a small cavity and the infection spread deep into my jawbone, requiring a complex surgery. Please go to a proper dental hospital before it gets complicated.

They are hollow spaces caused by bacterial acid destroying your tooth tissue. If you see any black spots or feel sensitivity, please get it checked by a qualified dentist immediately to prevent deeper nerve damage.

Actually, cavities are not made of anything, they are just empty holes caused by germs eating our teeth, ho na. We must keep our mouth clean so that these germs don't make home inside our teeth.

A cavity is technically an empty void in the enamel. My dentist explained that acid produced by oral bacteria feeding on sugar dissolves the calcium and phosphate minerals of your enamel, leaving behind a decayed, hollowed-out area.

Bhai, cavity koi cheez nahi hai, woh bas daant sda kar jo khali jagah banti hai wahi hai, haan. Sadan me bacteria aur ganda khana jama ho jata hai, toh dentist se saaf karwana hi padega.

It's just missing tooth structure! Plaque bacteria produce acid from carbs, which eats away your enamel and creates a physical hole. Tracking your daily sugar intake on fitness apps is a great way to prevent this from happening.

They are basically holes formed from eroded tooth structure due to plaque and acid. Since metabolic issues can sometimes affect oral health, I always try to be cautious and get a dentist's opinion rather than guessing what's wrong.
