Should You Repair a Chip in Your Porcelain Crown?

Porcelain dental issues?

Recently, I bit down on a small stone while eating, which caused a small hole to form at the edge of my porcelain crown (with a metal core).
Although the hole hasn't expanded, it has created a tactile discomfort, making that area feel rough.
Should I get it repaired, or can I leave it as is?

If the cavity is not very large, simply smoothing out the rough edges will suffice.
However, if the cavity is large, it may be necessary to consult a prosthodontist to evaluate whether it can be repaired.

When it comes to a chipped porcelain crown, especially one that has a metal core, there are several factors to consider regarding whether or not to repair it. A chip in a porcelain crown can lead to various issues, including aesthetic concerns, functional problems, and potential health risks.

Aesthetic Concerns: The first thing to consider is the appearance of the crown. A chip can make the crown look less appealing, especially if it is in a visible area, such as the front teeth. If the chip is small and not very noticeable, you might choose to leave it as is. However, if it is affecting your confidence or the overall look of your smile, repairing it would be advisable.

Functional Problems: A chipped crown can lead to functional issues. If the chip is causing discomfort or if you feel that the rough edge is irritating your tongue or gums, it is a good idea to have it repaired. A rough edge can also lead to difficulties in chewing or biting, which can further exacerbate the problem. Additionally, if the chip is significant enough to affect the bite, it could lead to uneven wear on adjacent teeth or even jaw discomfort over time.

Health Risks: Leaving a chip unrepaired can pose health risks. A chip can create a space where bacteria can accumulate, leading to potential decay of the underlying tooth structure. If the metal core of the crown is exposed, it can also lead to corrosion over time, which may result in further complications. Moreover, if the chip is large enough to compromise the integrity of the crown, it could lead to a fracture, necessitating a more extensive and costly repair or replacement.

Repair Options: If you decide to repair the chip, there are a few options available. Minor chips can often be smoothed out by a dentist, restoring the crown's surface and improving comfort. In some cases, a composite resin can be applied to fill in the chip, which can be color-matched to the existing crown for a seamless appearance. However, if the damage is extensive, you may need to consider replacing the crown entirely.

Consultation with a Dentist: It is crucial to consult with your dentist regarding the chip. They can assess the extent of the damage and recommend the best course of action. They may take X-rays to ensure that the underlying tooth is healthy and that there are no other issues that need to be addressed.

In conclusion, while a small chip in a porcelain crown may not seem like a significant issue, it is essential to consider the aesthetic, functional, and health implications. If the chip is causing discomfort or affecting your confidence, it is advisable to seek repair. Regular dental check-ups can help monitor the condition of your crowns and ensure that any issues are addressed promptly, maintaining both your oral health and the longevity of your dental work.
