Can an all-ceramic crown chip?

Chipping is a documented technical complication; a 2021 overview ranked it first among technical complications of zirconia restorations.[F4] A 2022 meta-analysis found that, for tooth-supported veneered zirconia restorations, fracture or chipping was about four times as likely as loss of retention—but that compares two ways things can go wrong; it is not chipping incidence.[F5] Clinical data for monolithic designs are still short in follow-up (mean exposure 1.07 years, range 0.3 to 2.1 years).[F6] Whether it will occur for you varies by person and requires a dentist’s assessment.

I grind my teeth. Does that mean I cannot get an all-ceramic crown?

Current evidence does not support “if you grind your teeth, the crown will certainly fail”: the 2018 meta-analysis did not support an association for ceramic restorations overall (odds ratio 1.10, 95% confidence interval 0.43 to 2.8, very low GRADE).[F11] In a 2026 trial that did not allow protective occlusal guards, no technical complications occurred in any of the four groups over three years, and differences between bruxism and non-bruxism groups were not statistically significant.[F12][F13] But this does not mean “bruxism has no effect.” The 2018 overall odds ratio had an upper confidence limit of 2.8, so a clear increase in risk cannot yet be excluded[F11]; the 2026 trial had only 21 to 27 people per group, followed them for only 3 years, and had numerically lower success in the bruxism groups.[F12] The higher 2018 risk value also came from anterior ceramic veneers, not crowns.[F11] Suitability and whether to add occlusal management require a dentist’s assessment of your condition.

Will an all-ceramic crown damage the natural tooth opposite it?

The consistent direction in the literature is that ceramic materials generally cause more wear of opposing posterior natural enamel than natural-tooth contact[F9], and zirconia was on the higher-wear side in all three studies.[F8][F9][F10] What differs is material ranking: the 2024 network meta-analysis found 82.5 µm more wear for metal-ceramic and 40.1 µm more for zirconia than natural-tooth opposition, while lithium disilicate was only 5.0 µm more and its interval crossed 0.[F8] The 2026 meta-analysis instead placed monolithic zirconia and lithium disilicate on the higher-wear side; its feldspathic-ceramic group was not significant (p = 0.06).[F9] A small study followed for 36 months, with 10 people analysed, measured mean maximum vertical loss of 216 µm in teeth opposing zirconia crowns, about twice natural-tooth contact, but comparable with other dental ceramics.[F10] These are population-level measurements, not a prediction for you.
