Regarding the issue of silver powder?
Hello, Director Tseng: Due to neglecting oral hygiene during my childhood, I have many dental fillings.
A few days ago, while chewing, I noticed some particles being expelled, and upon inspection, I realized it was amalgam from my dental fillings.
I discovered this time, but I am concerned about how much I may have ingested previously.
I would like to ask you, Director Tseng, will the amalgam be expelled from the body, or could it remain and cause harm? What should I do in this situation? Thank you for taking the time to respond!

Hello, sir: Thank you for your inquiry.
I would like to respond to your question and provide the following suggestions:
1.
Generally speaking, the use of silver amalgam for filling cavities has a long history.
Silver amalgam is a type of silver-mercury alloy that has good stability and hardness.
However, the mercury content has long raised concerns among scholars regarding the risk of chronic toxicity.
That said, if the silver-mercury alloy is properly mixed, this issue should not occur.
2.
Regarding the potential for corrosion in silver amalgam fillings, it is recommended to have regular dental check-ups.
If there is any loosening or fracturing of the silver amalgam filling, it should be replaced.
Finally, I wish you peace and happiness!

More Info
Ingesting dental silver fillings, commonly known as amalgam, raises valid concerns regarding potential health risks. Dental amalgam is a mixture of metals, primarily composed of silver, mercury, tin, and copper. While it has been widely used for dental restorations due to its durability and strength, there are ongoing discussions about the safety of mercury exposure from these fillings.
First and foremost, it is essential to understand that the mercury in dental amalgam is in a stable form when mixed with other metals. This stability means that, under normal circumstances, the risk of mercury leaching into the body is minimal. However, factors such as wear and tear of the filling, grinding of teeth, or improper dental work can lead to the release of small particles, which may be ingested.
If you have accidentally ingested a small amount of dental amalgam, it is generally considered to be of low risk. The human body can typically handle small quantities of metals, and they are often expelled through the digestive system. However, if a significant amount is ingested or if you experience any unusual symptoms, it is crucial to seek medical attention. Symptoms of mercury exposure can include gastrointestinal distress, neurological issues, and other systemic effects, although these are rare with small exposures.
In your case, since you mentioned that you have been unknowingly ingesting particles from your dental filling, it would be prudent to consult with a dentist. They can evaluate the condition of your amalgam fillings and determine if they need to be replaced or removed. If the fillings are deteriorating, it may be necessary to replace them with alternative materials, such as composite resins or ceramics, which do not contain mercury.
Additionally, if you are concerned about the potential for mercury accumulation in your body, you might consider undergoing a medical evaluation. Blood and urine tests can help assess mercury levels and determine if any action is needed. It is also important to maintain regular dental check-ups to monitor the condition of your fillings and overall oral health.
Regarding the removal of amalgam fillings, it is essential to have this procedure done by a qualified dentist who is experienced in safe amalgam removal techniques. This process often involves the use of rubber dams and high-volume suction to minimize exposure to mercury vapors and particles. Some dental practices may have specialized equipment for this purpose, which can further reduce risks associated with mercury exposure.
In conclusion, while ingesting small amounts of dental amalgam is generally not harmful, it is wise to be proactive about your dental health. Regular dental visits, proper oral hygiene, and addressing any concerns with your dentist can help ensure that your dental restorations remain safe and effective. If you have any lingering concerns about mercury exposure or the condition of your fillings, do not hesitate to seek professional advice. Your health and peace of mind are paramount.
