Are Cavities Reversible?

If you’ve been on Pinterest any time recently, you’ve probably seen personal or sponsored posts that have something to do with “healing cavities the natural way” or “reversing tooth decay without seeing your dentist.”

But could these headlines be too good to be true?

Yes and no.

The truth is, a full blown cavity cannot be fixed, healed, or have the tooth “grow back” by using some magic formula in your bathroom. But if the cavity is only in the beginning stages — we’re talking enamel demineralization on the most outer layers of the tooth — then it can be reversed before an actual “hole” forms in your enamel.


Demineralization: Phase One of Tooth Decay

Before tooth decay actually works its way through the tooth, it must first target a healthy area of enamel. The first stages involve eating away the outermost layers, etching the tooth and creating a weak spot. As more acids come into play, the enamel starts to appear chalky or white compared to the tooth around it. At this point, the surface is demineralized and prime for a cavity to form at any second.


Intercepting Before it’s Too Late

Once a tooth is demineralized, you have an important choice to make: treat the area of weakened enamel to prevent a cavity and re-strengthen your tooth, or wait it out and allowing the cavity to form, then get a filling.

The less invasive and more holistic approach would be to remineralize the tooth and prevent the cavity. This can be done by:


  • Cleaning the area more thoroughly each day
  • Seeing your dentist for a professional strength fluoride treatment
  • Optional treatments in your dentist’s office
  • Getting a prescription fluoride to use at home
  • Changing your habits to limit acid exposure to the teeth


If you suspect that you have a demineralized tooth or have a history of frequent cavities, call Eternity Dental in Mooroolbark to schedule an appointment.
