Will zirconia crowns cause tooth decay?

What Are Cavities, and How Do They Form?

Cavities occur when bacteria in dental plaque produce acidic substances that erode tooth enamel, eventually leading to tooth decay. When food particles remain on the teeth and aren’t cleaned properly, bacteria use these food particles to form plaque. Over time, the accumulation of plaque wears down the tooth surface, causing small holes that eventually develop into cavities.

Do Zirconia Crowns Accumulate Plaque?

Due to their dense and smooth material, zirconia crowns are resistant to plaque buildup and do not conduct temperature, reducing the likelihood of tartar formation. While zirconia crowns themselves do not develop cavities, patients should be mindful of the seal between the natural tooth and the crown. If gaps or poor bonding exist during crown installation, bacteria can infiltrate between the crown and the natural tooth, causing decay.

Conclusion

In summary, zirconia crowns themselves do not develop cavities, but the natural tooth underneath can still be affected if installation or maintenance isn’t thorough. Choosing a skilled dental professional and maintaining oral hygiene are essential.
