How fast do cavities develop?

My dentist told me cavities don't just appear overnight, they take around several months to a year to actually form a proper hole. But once it crosses the enamel and hits the inner part, it starts hurting like crazy super fast. Better to get it checked early.

Honestly, I'm too tired to even brush my teeth some nights, but then I remember how fast my last cavity grew and I jump out of bed. It took about 6 months of me ignoring a small black spot for it to turn into a full root canal. Don't be lazy like me, brush twice!

Please don't worry too much, cavities develop very slowly over many months. If you have noticed a small spot, a quick visit to a dentist can easily fix it with a simple filling before it causes any pain. Take care.

I ignored a tiny sensitivity in my molar for about 8 months thinking it was normal. By the time I went to the doc, the cavity had deep roots and I needed a proper filling. It takes time to build up, but once it starts, it won't stop on its own.
