Pinkish Teeth: Causes and Solutions for Dental Sensitivity - Dentistry

The teeth appear light pink?


Hello, Doctor.
My upper front tooth (tooth number 11) had a chip due to external force a long time ago.
It was initially restored with composite resin, but due to a deeper and heavier bite, the resin would not last long and would fall off.
After consideration, I decided to follow the dentist's recommendation to reduce the tooth size and place a full porcelain crown.
Since the X-ray results showed no issues with the nerve, I have not undergone root canal treatment for now.
During the reduction process, I received a significant amount of anesthesia, but when the dentist worked on the inner lower side of the front tooth, I still experienced noticeable discomfort.
After the procedure, the dentist showed me a photo indicating a faint pink area (approximately one-fourth to one-third of the area above the lower part of the tooth).
It has been four days since the temporary crown was placed, and overall, there are no issues, but when chewing or speaking, if my lower teeth or hard food touch that area, I feel a significant aching sensation.
Pressing that area with my hand also elicits a strong response.
Although I can eat, it is somewhat bothersome.
I would like to ask you, Doctor, what could be the cause of this situation? Is it possible for the full porcelain crown to change? Is root canal treatment a solution? Or are there other possible options (unless absolutely necessary, I would prefer to preserve the nerve of this tooth)? Thank you, Doctor.

Hello: It is recommended to observe for about a month.
If it is a "reversible" pulpitis, the symptoms will gradually decrease, and once asymptomatic, the all-ceramic crown can be cemented.
However, if there is concern that cementing the all-ceramic crown may lead to "irreversible" pulpitis, it may be considered to perform a root canal treatment before cementing the crown.
Currently, it is not possible to predict the course of pulp inflammation; therefore, it is advised to be cautious and avoid biting hard objects, grinding teeth at night, or frequently protruding the jaw, among other actions.

Understanding dental sensitivity, especially when it involves changes in color or texture of the teeth, can be quite complex. In your case, the pinkish hue observed on your upper front tooth (tooth #11) after the crown preparation could indicate several underlying issues that need to be addressed.

Firstly, the pinkish color you see is likely due to the exposure of the dental pulp or the dentin layer beneath the enamel. When the enamel is worn down or damaged, it can expose the dentin, which is more sensitive and can lead to discomfort when exposed to temperature changes or pressure. This sensitivity can be exacerbated by the dental procedure you underwent, especially if there was significant drilling or manipulation of the tooth structure.

The discomfort you experience when chewing or speaking, particularly when pressure is applied to that area, suggests that the tooth may be experiencing some degree of inflammation or irritation. This could be due to several factors:
1. Pulpal Inflammation: Even if the X-ray did not show any issues with the nerve, the trauma from the drilling and the exposure of the dentin can lead to temporary inflammation of the pulp, which may cause sensitivity.

2. Gingival Recession: If the gum tissue around the tooth has receded, it can expose the root surface, which is not covered by enamel and is more sensitive to stimuli.

3. Crown Fit and Occlusion: If the temporary crown is not fitting properly or if your bite is off, it can lead to discomfort when biting down. This misalignment can put undue stress on the tooth, leading to pain.

Regarding your question about whether the placement of a full porcelain crown could change the situation, it is possible. A well-fitted crown can help protect the tooth structure and alleviate some sensitivity. However, if the underlying issue is related to pulpal inflammation, the crown alone may not resolve the discomfort.

As for root canal treatment, it is often considered when there is irreversible damage to the pulp, which can lead to severe pain and infection. If the sensitivity persists or worsens, or if you begin to experience more severe symptoms such as swelling or prolonged pain, a root canal may indeed become necessary. However, if the sensitivity is manageable and does not worsen, monitoring the situation for a short period may be advisable.

In the meantime, here are some recommendations to help manage your sensitivity:
- Use Desensitizing Toothpaste: These products can help block the transmission of sensation from the tooth surface to the nerve.

- Avoid Extreme Temperatures: Try to stay away from very hot or cold foods and drinks that can trigger sensitivity.

- Gentle Oral Hygiene: Be gentle when brushing and flossing around the affected tooth to avoid exacerbating the sensitivity.

- Follow-Up with Your Dentist: Regular check-ups are essential to monitor the situation. If the sensitivity does not improve or worsens, your dentist may need to reassess the tooth and consider further treatment options.

In conclusion, while the pinkish hue and sensitivity of your tooth may be concerning, it is essential to monitor the situation closely. If symptoms persist, further evaluation, including the possibility of root canal treatment, may be necessary. Always communicate openly with your dentist about your symptoms and concerns to ensure the best possible care for your dental health.
