Using dental floss can cause soreness or discomfort in the interdental spaces?
Hello, doctor.
Previously, I had a filling done on the second-to-last tooth in the upper left row (on the side).
After eating, food gets stuck there frequently, and it not only causes discomfort but also pain.
When I use dental floss and it touches the gum, it becomes even more uncomfortable.
I would like to know if I might have a cavity again? (I don’t experience pain when not eating.) The location is in the gap between the last two teeth, and the other gaps do not have this issue.
When I press on that gap with my finger, it also feels swollen and painful...
Thank you for your help.

Hello: It is possible that the dental filling material has come loose, leading to sensitivity to acids and softness.
It is recommended to have the original dentist check it again for confirmation.
Thank you!

More Info
Tooth pain and discomfort, especially when using dental floss, can be a common issue that many people experience. Based on your description, it sounds like you may be dealing with a few potential dental problems that could be causing the discomfort in your left upper second-to-last tooth.
Firstly, it’s important to consider the possibility of recurrent decay. Since you mentioned that this tooth has previously been filled, it is possible that the filling may have failed or that new decay has developed around the margins of the filling. This can happen if food particles are getting trapped in the area, leading to irritation and inflammation of the gums, which can cause pain when you use dental floss or when pressure is applied to the area. If the tooth is indeed decaying again, it may not hurt when you are not eating or flossing, but the irritation from food particles can exacerbate the discomfort.
Another possibility is that you may be experiencing gum disease, which can manifest as tenderness and swelling in the gums, particularly around the areas where food tends to get trapped. If the gums are inflamed, using dental floss can aggravate the sensitivity, leading to pain. This inflammation can be a result of plaque buildup, which can occur even in areas that seem to be well cared for.
Additionally, the discomfort you feel when flossing could be due to improper flossing technique. If the floss is being pushed too hard against the gums, it can cause trauma and pain. It’s essential to use a gentle sawing motion and to curve the floss around the tooth to avoid damaging the gum tissue.
To address your concerns, here are some steps you can take:
1. Visit Your Dentist: The most important step is to schedule an appointment with your dentist. They can perform a thorough examination, including X-rays if necessary, to determine if there is any decay or other issues with the tooth or surrounding gums.
2. Maintain Good Oral Hygiene: Continue to brush your teeth at least twice a day and floss daily, but be gentle when using floss. Consider using a softer type of floss or a floss pick if you find traditional floss uncomfortable.
3. Use Antimicrobial Mouthwash: An antimicrobial mouthwash can help reduce plaque buildup and inflammation in the gums, which may alleviate some discomfort.
4. Avoid Certain Foods: If you notice that certain foods exacerbate the pain, try to avoid them until you can see your dentist. Sticky or hard foods can worsen the situation.
5. Pain Management: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help manage discomfort temporarily, but they should not be a substitute for professional care.
6. Consider Dental Products for Sensitivity: There are toothpaste and mouth rinses specifically designed for sensitive teeth that may help alleviate discomfort.
In summary, while it is possible that you may be experiencing recurrent decay or gum disease, only a dental professional can provide an accurate diagnosis and appropriate treatment. It’s crucial to address these symptoms promptly to prevent further complications. Regular dental check-ups and maintaining good oral hygiene are essential for preventing such issues in the future.
