When a tooth begins to wear down, your dentist may recommend a dental crown to help sustain and preserve it for a period of time. Sometimes, however, a dental crown can cause a myriad of problems inside the mouth after it’s cemented. When this happens, patients typically blame their dentist for something that they did wrong. But this is not always the case. Let’s look over some scenarios that can cause problems with your dental crown, and steps you can take to remedy the issue at hand.
Open margins on the dental crown
When a crown is prepared inside your mouth, the area that your dentist prepares near the gum line is called the “margin” and it’s where the dental crown will sit on top of. The crown that is fabricated for you has to sit flush with this margin, otherwise bacteria and other elements can cause secondary decay to your tooth. Open margins, besides causing cavities, can lead to issues with tooth sensitivity (especially to hot and cold), and can potentially lead to additional dental procedures such as a root canal or a tooth extraction.
Dental crown is too tall
When a dental crown a seated, sometimes the lab fabricating the crown makes the crown slightly too tall. If your dentist does not make proper adjustments to the crown before he or she cements it in your mouth, then a common symptom you will feel is that your crown will hurt whenever you bite down. This is a common complaint that a lot of patients feel. If you are suffering from this problem, just return to your dentist and have him check to see if the crown is still too high. He will use marking paper (called articulating paper) to check of there are still high points on the crown that need adjustment. If you do not get the tooth adjusted, there is a chance that they tooth may end up fracturing, requiring you to have to get the tooth removed.
There is an opening between the crown and the adjacent tooth
Sometimes there is a gap between your dental crown and your natural tooth structure. What happens in these cases is that food and other particles can get trapped and irritate your gum tissue. These patients have to constantly floss in between their crown to get food particles out. This opening can lead to long term gum disease, and unfortunately, the only cure to the problem is to get the crown replaced.
Your tooth is sensitive to cold after your crown placement
If your tooth is sensitive to cold after your dental crown is cemented, there could be a few issues that could be causing this:
- You have an open margin: As previously mentioned, an open margin is when the dental crown is slightly designed incorrectly by the lab, and is not completely sealing your tooth all the way around. If this is the case, your dentist should replace your dental crown.
- The tooth is prepared close to the nerve chamber: Sometimes a dental cavity can penetrate deep into your tooth. Once the tooth is prepared for your crown, it will get sensitive espicially to hot and cold elements. If this is the case, and your symptoms do not improve over time, then your dentist will recommend that the tooth get a root canal.
- The dental crown was prepared on a tooth that was grinded down: Bruxers and grinders have a high susceptibility to cold sensitivity after their tooth is prepared for a crown. This is because the preparation is also close to the nerve tissue of the tooth making it sensitive to hot and cold. Root canal therapy may also be recommended for these patients.

Frequently Asked Questions
How do you know when a dental crown is bad?
If your dental crown is causing any issues such as cold sensitivity, pressure sensitivity, or issues when you are chewing or biting down, then there is something not quite right with your dental crown. If you are having any of these symptoms, check with your local dentist to see if he or she can identify the problem.
Do teeth decay under dental crowns?
Teeth can decay under dental crowns if the crown has an open margin as previously mentioned. Decay takes time to form, so a lot of times it may even take years before you know something is wrong. Many times these teeth end up needing to have their crowns replaced, or may even end up needing root canals or other extensive dental therapy.

Sometimes a dental crown can be put on incorrectly, leaving a small gap between the tooth structure and the crown. These caps need to be replaced immediately as a host of problems can occur if the patient is dismissed with this issue.
