Dental Fillings: Is It Normal to Feel Loose After Silver Filling? - Dentistry

Condition after silver powder excavation and filling?


Hello, I visited Dentist A for my lower right second to last tooth, where Dentist B had filled it with amalgam 12 years ago.
Dentist A removed the old amalgam and refilled it.
I would like to know if it is normal to feel looseness in the tooth after the filling.
Additionally, I keep smelling the odor from the removed amalgam and feel swelling inside, along with a sensation of bleeding.
I am a bit concerned about how long it usually takes to determine if this is just a natural phenomenon after the filling, or if there is something more serious?

The newly placed silver filling will be loose for about 24 hours before it hardens completely.
If you continue to feel swelling after the procedure, you should return for an examination to check if the occlusal surface is too high or if the filling is pressing against the gums.

After receiving a silver filling, it is not uncommon to experience some discomfort or unusual sensations in the treated tooth. When you mention that your tooth feels "loose" after the filling, it is important to understand the context of dental fillings and the healing process involved.

Firstly, when a dentist places a silver filling (which is typically a silver amalgam made of a mixture of metals including silver, mercury, tin, and copper), the material needs time to set and harden. Generally, it takes about 24 hours for the filling to fully harden and achieve its maximum strength. During this initial period, it is possible to feel some looseness or instability in the tooth, especially if the filling was large or if the tooth structure was significantly compromised prior to the procedure. If the feeling of looseness persists beyond the first day, it may warrant a follow-up visit to your dentist to ensure that the filling is properly seated and that there are no underlying issues.

Regarding the sensation of swelling and bleeding that you mentioned, these symptoms can be concerning. After a filling, some patients may experience mild inflammation of the gums surrounding the treated tooth, especially if the filling was placed close to the gum line or if the procedure involved some manipulation of the gum tissue. However, persistent swelling, bleeding, or a foul odor could indicate an infection or an issue with the filling itself. It is crucial to communicate these symptoms to your dentist as soon as possible. They may need to examine the area to rule out any complications such as an abscess or improper sealing of the filling, which could lead to further dental issues.

In terms of recovery time, while the initial discomfort may subside within a few days, any persistent symptoms such as swelling or bleeding should be evaluated by your dentist. They can provide a thorough examination and determine if any additional treatment is necessary.
It is also worth noting that the sensation of "scraping" or "roughness" that some patients report after receiving a filling can be attributed to the filling material not being polished adequately or the filling being slightly over-contoured. If you feel that the filling is rough or has sharp edges, it is advisable to return to your dentist for adjustments. They can smooth out the filling to ensure that it is comfortable and does not interfere with your bite.

In summary, while some initial discomfort and sensations are normal after receiving a silver filling, persistent symptoms such as looseness, swelling, and bleeding should not be ignored. It is essential to maintain open communication with your dental care provider and seek follow-up care if you have any concerns about your recovery. Regular dental check-ups and prompt attention to any unusual symptoms can help ensure the long-term health of your teeth and gums.
