Bitter and Medicinal Taste After New Dental Crown: What to Do? - Dentistry

Saliva has a bitter or medicinal taste?


Hello, Doctor.
I recently had a new dental crown made, but during the later stages of wearing the temporary crown, I experienced an intermittent bitter and medicinal taste in my mouth.
After trying on the new permanent crown (all-ceramic crown), I still have the same symptoms.
I did not undergo root canal treatment, and after researching, I found that some people mentioned it could be due to the temporary adhesive leaking, while others said that the adhesive itself has no taste.
If the adhesive is leaking, does that mean the crown is not properly sealed? Can I ask my dentist to help me permanently cement it?

Hello: 1.
Temporary adhesives usually have an odor, and if there is leakage or food accumulation due to ill-fitting dental braces, it can indeed cause an unpleasant smell.
2.
Ill-fitting braces are not recommended for permanent fixation.
3.
The fit must be assessed by a dentist through clinical examination and corroborated with X-rays, not solely based on the presence of an odor.
Thank you!

Experiencing a bitter or medicinal taste after getting a new dental crown can be concerning, and it’s important to address this issue promptly. There are several potential causes for this taste, and understanding them can help you determine the best course of action.

Firstly, the bitter taste you are experiencing could be related to the materials used in the dental crown or the temporary cement that was applied during the fitting process. Temporary cements often have different properties compared to permanent cements, and some patients report a taste associated with these materials. If the temporary cement is leaking or not sealing properly, it could lead to food particles or bacteria entering the space between the crown and the tooth, which may also contribute to an unpleasant taste.

Another possibility is that the taste could be a reaction to the dental materials themselves. Some individuals may have sensitivities or allergies to certain dental materials, including metals or resins used in crowns. If you suspect this might be the case, it’s essential to discuss this with your dentist, who may recommend alternative materials that are less likely to cause a reaction.

In addition, if you have not undergone root canal treatment, the taste could also be related to underlying dental issues. For example, if there is decay or infection present in the tooth that the crown is covering, this could lead to a foul taste. It’s crucial to ensure that the tooth is healthy before placing a permanent crown.

Regarding the concern about the crown not fitting properly, if the crown is not sealing well, it can lead to leakage of the temporary cement, which might explain the taste. A poorly fitting crown can also lead to other complications, such as gum irritation or infection. If you suspect that the crown is not fitting correctly, it’s advisable to return to your dentist for an evaluation. They can check the fit of the crown and make any necessary adjustments.

In terms of what you should do next, here are some steps to consider:
1. Schedule a Follow-Up Appointment: Contact your dentist to discuss the taste you are experiencing. Make sure to mention that it has persisted even after the installation of the permanent crown.

2. Discuss Your Symptoms: Be open about all your symptoms, including the taste, any discomfort, or changes in your oral health. This information will help your dentist diagnose the issue more effectively.

3. Request an Evaluation: Ask your dentist to evaluate the fit of the crown and check for any signs of decay or infection in the underlying tooth.

4. Consider Material Sensitivities: If you have a history of allergies or sensitivities to dental materials, inform your dentist. They may suggest alternative materials for your crown.

5. Maintain Oral Hygiene: Continue to practice good oral hygiene by brushing and flossing regularly. This will help prevent any potential issues from worsening.

6. Monitor Your Symptoms: Keep track of any changes in taste or other symptoms. If the taste worsens or if you experience pain, swelling, or other concerning symptoms, seek dental care immediately.

In conclusion, while a bitter or medicinal taste after getting a dental crown can be unsettling, it is often manageable with the right approach. By communicating openly with your dentist and following their recommendations, you can work towards resolving the issue and ensuring that your dental crown functions properly without any unpleasant side effects. Remember, your oral health is paramount, and addressing any concerns promptly can lead to better outcomes.
