Dental floss is stuck between the teeth and cannot be removed?
Hello Dr.
Lin, last month while flossing, I found that the dental floss gets stuck between my upper left second molar (which was filled with silver amalgam about five years ago) and I couldn't pull it out.
After that, no matter what I tried, the floss could only go in but wouldn't come out, so I had to give up using dental floss and switched to interdental brushes to clean the space between that molar.
However, recently, whenever I bite into something slightly hard, I feel a slight sensitivity in that molar, but as long as I chew slowly, the pain goes away.
If I don't bite on that molar, there is no pain.
I would like to ask you, Dr.
Lin, what would you recommend doing in this situation? Is there a risk of mercury poisoning during the process of replacing the silver amalgam? Additionally, are there any remedies for the symptoms mentioned above? Thank you, Dr.
Lin.

Hello: It is recommended to first take an X-ray to confirm if there are secondary caries or other ongoing cavities.
During the process of removing the amalgam, the dentist should use a rubber dam and a more powerful suction device to remove the amalgam debris.
If re-restoration is needed, it is advisable to consider using an inlay or a crown (commonly referred to as 3D dental sculpting).

More Info
Dealing with dental issues, especially after experiencing pain or discomfort, can be quite challenging. Based on your description, it seems that you are facing a couple of interconnected problems: the stuck dental floss, discomfort in your tooth, and concerns regarding the silver filling (which likely contains mercury). Let's break down the issues and provide some guidance.
Stuck Dental Floss
When dental floss gets stuck between teeth, it can be frustrating and may indicate a few potential issues. It could be that the filling has altered the shape of the tooth or that there is some decay or gum disease present that is causing the floss to catch. Here are some tips for dealing with this situation:
1. Avoid Force: If the floss is stuck, do not pull too hard as this can damage your gums or the filling. Instead, gently wiggle the floss back and forth to see if you can free it.
2. Use Alternative Tools: Since you mentioned switching to interdental brushes, this is a good alternative. They can be more effective in cleaning between teeth, especially if the space is tight or irregular.
3. Consult Your Dentist: Given that the floss is getting stuck, it’s crucial to visit your dentist. They can assess the filling and the surrounding tooth structure to determine if there is an underlying issue that needs to be addressed, such as decay or a poorly fitting filling.
Tooth Sensitivity
The slight discomfort you feel when biting down on harder foods could be a sign of a few different issues:
- Filling Integrity: If the filling is compromised or if there is decay beneath it, this could lead to sensitivity.
- Gum Health: If there is inflammation or infection in the gums surrounding the tooth, this can also cause discomfort when pressure is applied.
Mercury Concerns
Regarding your concern about mercury toxicity from silver fillings (amalgam), it’s important to note that while amalgam fillings do contain mercury, they are considered safe by many dental and health organizations when used properly. The risk of mercury exposure from intact fillings is minimal. However, if you are considering having the filling replaced, it is essential to consult with a dentist who is experienced in safe removal techniques to minimize any potential exposure.
Recommendations
1. Dental Visit: Schedule an appointment with your dentist as soon as possible. They can evaluate the filling, check for any signs of decay, and provide treatment options. If the filling needs to be replaced, they can discuss the best materials for your situation.
2. Pain Management: In the meantime, if you experience discomfort, over-the-counter pain relievers like acetaminophen or ibuprofen can help manage the pain. However, be sure to follow the recommended dosages.
3. Dietary Adjustments: While you are experiencing sensitivity, it may be wise to avoid very hard or sticky foods that could exacerbate the discomfort. Stick to softer foods that are easier to chew.
4. Oral Hygiene: Continue to maintain good oral hygiene practices. Brush twice a day and use mouthwash to help keep your mouth clean. If you find flossing difficult, consider using a water flosser, which can be gentler on sensitive areas.
5. Monitor Symptoms: Keep track of any changes in your symptoms. If the discomfort worsens or if you notice swelling or other signs of infection, seek dental care promptly.
In summary, while dealing with dental issues can be daunting, addressing them with your dentist will provide you with the best course of action. Regular check-ups and maintaining good oral hygiene are key to preventing future problems.
