Difference Between Tooth Erosion & Decay

Acid erosion and cavities are not the same—but they can both be harmful to teeth. Here are some of the main differences between tooth erosion and tooth decay:


  • Cavities are generally localised to specific hard-to-clean areas of the teeth.
  • They form when foods with sugar or starches are turned into acids by the bacteria in your mouth covering tooth surfaces: dental plaque.
  • Bacteria bind to saliva components bound to tooth surfaces to form plaque, which clings to teeth.
  • Over time, the acids produced by bacteria in plaque can cause the enamel to break down and a cavity to form, which may require filling by a dentist.


  • Acid erosion occurs across the whole tooth surface that has been exposed to acid.
  • It is the result of either intrinsic (stomach acids) or extrinsic acids (from food or drinks) on the surface of tooth enamel.
  • Acidic softening can weaken enamel over time, making it appear yellow and dull.
  • Even if your teeth are clean and healthy, you can still experience acid erosion.
  • Acid erosion may cause teeth to become susceptible to sensitivity.

Tooth enamel is irreplaceable, so acid erosion presents a risk to your teeth. Over time, acid erosion can lead to reduced enamel thickness and a change in shape, texture and appearance of your teeth, which can also cause teeth to become sensitive.

Since it is not easily detectable to the naked eye, only a dentist can properly assess the effects of acid erosion on your tooth enamel. Just take note that dentists cannot fix enamel erosion, as enamel doesn’t regenerate itself. Therefore, it’s important that you take steps to protect your teeth.
