After dental filling, it cannot be removed?


I had a dental filling done about two weeks ago, and I still experience some pain when eating.
Additionally, I have difficulty using dental floss sticks because something seems to be stuck.
The filling is located on the second-to-last tooth on the left side.
Could this be due to the floss stick being too thick, or is it plaque, or could the filling have come loose? Thank you, doctor, for taking the time to respond.

Hello: If the dental floss continues to get stuck, it is recommended to return to the original clinic for a check-up by the dentist.
Otherwise, the inability to clean properly may lead to gingivitis.

More Info


After a dental filling, experiencing pain and difficulty with flossing can be concerning and may indicate several potential issues. Given that you are about two weeks post-filling and still experiencing discomfort, it is essential to consider a few possibilities.

1. Post-Operative Sensitivity: It is not uncommon to experience some sensitivity after a dental filling, especially if the filling is deep or if the tooth was previously affected by decay. This sensitivity can last for a few weeks as the tooth settles down after the procedure. If the pain is mild and gradually improving, it may simply be a normal part of the healing process.

2. High Filling: Sometimes, a filling can be slightly too high, which means that when you bite down, the filled tooth makes contact before the surrounding teeth. This can lead to discomfort and pain when chewing. If you suspect this might be the case, it is advisable to return to your dentist for an adjustment.

3. Improper Flossing Technique: If you are having trouble with flossing, it could be due to the technique used or the type of floss. Some people find that thicker floss or floss picks can be difficult to maneuver around tight spaces. You might want to try waxed dental floss, which can slide more easily between teeth, or a dental tape that is designed for wider gaps.

4. Food Particles or Plaque Buildup: If food particles are getting stuck between your teeth, it could be due to the shape of the filling or the surrounding teeth. This can lead to discomfort and may require a professional cleaning to remove any plaque or debris that is trapped.

5. Filling Material Issues: In some cases, the filling material itself may not have adhered properly or could be causing irritation to the surrounding gum tissue. If the filling is loose or has fallen out, this could also lead to pain and difficulty with flossing.

6. Underlying Issues: If the pain persists or worsens, it may indicate an underlying issue such as an infection or inflammation in the tooth or surrounding gum tissue. This could require further evaluation by your dentist, possibly including X-rays to assess the situation.

In summary, while some discomfort after a filling can be normal, persistent pain and difficulty with flossing should not be ignored. It is best to schedule a follow-up appointment with your dentist to discuss your symptoms. They can provide a thorough examination and determine the best course of action, whether that involves adjusting the filling, providing a different type of floss, or addressing any other underlying issues. Remember, maintaining good oral hygiene and regular dental check-ups are crucial for preventing complications and ensuring your dental health.
