What Is Tooth Erosion?

Tooth erosion (sometimes known as acid erosion or dental erosion) occurs primarily when acids in your mouth wear away your tooth enamel, causing permanent damage over time. Enamel is the hard, white outer coating of your teeth.i While it’s the hardest substance in the human body,ii enamel does not contain any living cells so it cannot regenerate.iii Once enamel is worn away, the sensitive dentin layer underneath is exposed, which is yellow in appearance.

What Are the Signs of Tooth Erosion? Tooth Erosion Explained

You may not be able to see the effects of acid erosion yourself, but your dentist can check for early signs at the same time as they’re checking for tooth decay or gum disease.

Even if your teeth look healthy today, over time acids in everyday foods and drinks can still put enamel at risk. Here are 5 signs that you may be affected by acid erosion:

1. Rounded edges

The edges of your teeth are the most exposed to acid wear, so will tend to be worn away first.

2. Dull or Discolored

As the enamel wears away, your teeth may lose their shine, making them appear dull.

3. Yellowing

If a significant amount of enamel is worn away from the tooth, the slightly yellow dentin layer underneath can become more visible.

4. Translucent or See-Through

As more enamel wears away, teeth can become visibly thinner. As the enamel thins, the edges of your teeth can appear translucent.

5. Sensitivity

As the protective enamel wears away, the underlying dentin layer can become exposed. This can be one of the causes of sensitivity.

Fortunately, it’s easy to take action to reduce these risks. Find out more on how to protect against acid erosion.
