Q: Fixing Issues with Porcelain Crowns: Addressing Bite and Speech Problems

Hello： Before it is permanently bonded, there is still an opportunity to make adjustments to the shape and color. <br>It is recommended to discuss this with the original dentist, as it may have been intentionally designed to avoid occlusion, thereby reducing the risk of fracturin

I had four all-ceramic crowns placed on my front teeth (2/2), but two of them do not make contact with the lower teeth, causing air to escape while speaking?

A few months ago, I developed cracks in my front teeth, and I accidentally bit down on a metal chopstick, resulting in damage to the two central teeth.
They are also tilted to the sides, and there is some dark discoloration near the gums.
I am considering getting dentures, but since the two teeth on either side also have cracks, are misaligned, and have dark spots, I would like to have all four teeth treated at once.

I underwent root canal treatment a month ago, had temporary dentures for over a month, and have had fixed dentures for more than a month (which are not yet secured).
There has been no pain or discomfort, and they appear stable and aesthetically pleasing.
However, the two teeth on the left do not make contact with the lower teeth when biting, and I experience air leakage when speaking.
It seems like the teeth are not long enough.

Is there a way to remedy this situation? Thank you, doctor.

More Info

When dealing with issues related to porcelain crowns, particularly in the context of bite and speech problems, it is essential to understand the underlying causes and potential solutions. Based on your description, it seems that you have undergone significant dental work, including root canal treatment and the placement of temporary and permanent crowns. However, you are experiencing functional issues with your new crowns, specifically with the left side not making proper contact with the lower teeth and speech difficulties due to air leakage.

Firstly, it’s important to recognize that the fit and alignment of dental crowns are crucial for proper function. If the crowns are not adequately contoured or if they are too short, this can lead to issues with occlusion (the way your teeth come together when you bite) and can affect your speech. The fact that your left crowns do not touch the lower teeth suggests that they may need to be adjusted or remade to ensure proper occlusion.

Here are some steps you can take to address these issues:
1. Consult Your Dentist: The first step is to return to your dentist or the specialist who placed the crowns. Explain your concerns about the bite and speech issues. A thorough examination, including checking the occlusion, is necessary. Your dentist may use articulating paper to assess how your teeth come together and identify any high spots or areas that need adjustment.

2. Adjustments: If the crowns are too high or not properly aligned, your dentist can make adjustments. This may involve reshaping the crowns to ensure they fit better with the opposing teeth. Sometimes, minor adjustments can significantly improve the bite and alleviate speech issues.

3. Consider Lengthening the Crowns: If the crowns are indeed too short, your dentist may recommend remaking them to a longer length. This can help improve the contact with the opposing teeth and enhance your ability to bite and chew effectively.

4. Evaluate Speech Therapy: If the adjustments to the crowns do not fully resolve the speech issues, consider consulting a speech therapist. They can provide exercises and techniques to help you adapt to the changes in your mouth and improve your speech clarity.

5. Follow-Up Care: After any adjustments or remakes, ensure you have regular follow-up appointments to monitor the fit and function of your crowns. This will help catch any issues early and ensure that your dental work remains functional and comfortable.

6. Oral Hygiene: Maintain excellent oral hygiene, especially around the crowns, to prevent any future complications such as decay or gum disease. Use a soft-bristled toothbrush and fluoride toothpaste, and consider using an antibacterial mouthwash to keep the area clean.

In summary, addressing bite and speech problems related to porcelain crowns involves a collaborative approach with your dentist. By communicating your concerns and undergoing necessary adjustments, you can achieve a functional and aesthetically pleasing result. Remember, dental work is a process, and it may take a few visits to get everything just right. Don’t hesitate to advocate for your needs and seek the best possible outcome for your dental health.
