Issues with dental bridges and dental crowns?


Hello Doctor, I had a dental bridge with three crowns placed on my lower left molars over a decade ago.
Recently, I've been experiencing sensitivity in those teeth as well as in the three upper left molars.
Due to using one side for chewing, I have caused some wear on the enamel.
My dentist suggested that I need to undergo root canal treatment for both upper and lower teeth before getting crowns.
Is it possible to avoid root canal treatment since there are no cavities? If I do undergo root canal treatment, will it shorten the lifespan of my teeth? The dentist explained that after a root canal, I won't feel pain anymore, but just because I won't feel pain doesn't mean the tooth won't get infected.
If I have a root canal, will I still be able to receive signals from the tooth? I'm quite troubled by this.
Please help clarify, thank you.

Hello Huang Mei: If the teeth that require crowns are severely worn down, causing irreversible inflammation of the nerves, it is recommended to perform root canal treatment before placing the crowns.
This will prevent spontaneous pain from occurring after the crowns are placed, which would complicate the need for subsequent root canal treatment.

Dental bridges and crowns are common restorative dental procedures used to replace missing teeth or restore damaged ones. However, patients often have concerns regarding their longevity, sensitivity, and the necessity of root canal treatments. Let's delve into these concerns and explore potential solutions.


Understanding Dental Bridges and Crowns
Dental Bridges are prosthetic devices that fill the gap created by one or more missing teeth. They are anchored to adjacent teeth (abutments) and can be made from various materials, including porcelain, metal, or a combination of both. Crowns, on the other hand, are caps placed over a tooth to restore its shape, size, strength, and appearance. They can be used in conjunction with bridges or independently.


Common Concerns
1. Sensitivity and Pain: It's not uncommon for patients to experience sensitivity or pain after receiving a dental bridge or crown. This can be due to several factors:
- Occlusal Issues: If the bridge or crown is too high, it can lead to discomfort when biting down. This is often referred to as "high occlusion," and adjustments can be made by your dentist to alleviate this issue.

- Underlying Dental Issues: Sensitivity might indicate that there are underlying problems with the adjacent teeth or the gums. If the teeth are already compromised, the added stress from a bridge or crown can exacerbate the pain.

2. Root Canal Treatment: Your dentist may suggest root canal treatment if there is a risk of infection or if the tooth is already showing signs of decay or damage. While it is true that root canal treatment can prevent pain and infection, it also raises concerns about the longevity of the tooth:
- Longevity: Teeth that have undergone root canal treatment can last many years, but they may be more susceptible to fractures due to the loss of tooth structure. However, with proper care and the placement of a crown, the tooth can remain functional for a long time.

- Infection Risk: After a root canal, the tooth is devoid of nerves, which means you won't feel pain from that tooth. However, this does not mean the tooth is immune to infection. Regular dental check-ups are essential to monitor the health of the tooth and surrounding tissues.

3. Material Choices: The choice of materials for crowns and bridges can also affect sensitivity and durability. Porcelain-fused-to-metal crowns offer a good balance of aesthetics and strength, while all-ceramic crowns provide a more natural appearance but may not be as strong for posterior teeth.


Solutions and Recommendations
1. Consultation and Communication: It's crucial to maintain open communication with your dentist. If you're experiencing sensitivity or discomfort, discuss these symptoms thoroughly. Your dentist may need to adjust the occlusion or investigate further for any underlying issues.

2. Consider Alternatives: If root canal treatment is recommended but you're hesitant, discuss alternative options with your dentist. In some cases, if the tooth is not severely compromised, it may be possible to place a crown without performing a root canal.

3. Regular Check-ups: After receiving a bridge or crown, regular dental visits are essential. These check-ups allow your dentist to monitor the health of your teeth and gums, ensuring that any potential issues are addressed promptly.

4. Oral Hygiene: Maintaining excellent oral hygiene is vital for the longevity of dental restorations. Brush and floss regularly, and consider using an antibacterial mouthwash to reduce the risk of infection.

5. Seek a Second Opinion: If you're unsure about the recommended treatment plan, seeking a second opinion from another dental professional can provide additional insights and options.


Conclusion
Dental bridges and crowns are effective solutions for restoring function and aesthetics to your smile. However, concerns about sensitivity, the necessity of root canal treatments, and the longevity of these restorations are valid. By maintaining open communication with your dentist, exploring all treatment options, and adhering to a diligent oral hygiene routine, you can ensure the best possible outcomes for your dental health. If you have further questions or concerns, don't hesitate to reach out to your dental care provider for personalized advice.
