What happens when a porcelain crown chips?

A chip in your porcelain crown is a break or crack in the outer layer. Depending on its size and location, your dentist may have several options to address it.

Polishing and smoothing

If the chip is very small and doesn’t affect how you bite or speak, your dentist may simply polish the rough edges smooth. This prevents your tongue or cheek from catching on the chip and may be all that’s needed.

Repair with bonding

Small to medium chips can sometimes be repaired by applying tooth-colored material directly to the chipped area. This is often quicker and less expensive than replacement, though the repair may not be as durable as the original crown over time.

Full replacement

Larger chips, deep cracks, or damage that extends beneath the crown to the natural tooth below may require the crown to be removed and replaced with a new one. Your dentist will take this step if repair won’t restore function, appearance, or the crown’s long-term strength.

Important questions to ask your dentist

When you see your dentist about a chipped crown, ask:

• How deep is the chip? Is it only surface damage, or does it go through the crown material?
• Is the underlying tooth affected? If the natural tooth beneath the crown is cracked or damaged, the crown may need to come off for your dentist to assess or treat the tooth. See our guide on a chipped tooth if this is the case.
• Is the crown loose? If the crown is loose or the cement has failed, it may need to come out and be recemented or replaced. If this is the case, see our guide on a crown falling out.
• What are my options? Ask your dentist to explain repair vs. replacement, including the time and steps involved.
• What are the pros and cons? A repair may buy you time, but it may not last as long as a new crown. A new crown will likely be more durable but takes more time and steps.
• Can I see the crown? Ask your dentist to show you the chip and explain their recommendation on your x-rays or in person.
• What happens if I wait? A small chip may be fine to monitor, but a large chip or crack could worsen and allow bacteria to enter, damaging the underlying tooth.

How to evaluate your options

Your dentist’s recommendation will depend on the size, location, and cause of the chip, as well as the condition of the underlying tooth and crown cement.

If repair is possible, ask how long the repair typically lasts and whether your situation has any risk factors that might shorten its lifespan (for example, if you grind your teeth, a repair may chip again sooner).

If replacement is recommended, ask for an itemized explanation of the steps and what to expect. You can also ask whether a second opinion would help you feel confident in the decision.

Prevention tips

While porcelain crowns are strong, they can chip if you bite down hard on very hard objects (such as ice, hard candy, or popcorn kernels) or if you grind your teeth at night. If grinding is a factor, ask your dentist whether a night guard might help protect your crown and natural teeth.
