Gum pain while eating?


Hello, doctor.
About four to five years ago, I started experiencing symptoms where my gums in a specific area would hurt after eating certain foods (such as nuts).
The condition would improve after using dental floss to remove food particles from between my teeth.
I have mentioned this to my dentist during my cleanings, but they always said my gums looked healthy and there were no issues.
Two weeks ago (on September 5), I had gum pain and, as usual, used dental floss to clean, but the condition did not improve.
Whenever I eat in that area, it hurts.
Two days later (on September 7), I went for a dental cleaning, and even the day after (without eating anything in between), it still hurt when I ate.
On September 19 (two weeks after the incident), I specifically returned to the clinic to have my gums checked.
The dentist insisted that my gums looked normal (seeming a bit irritated) and said that as long as I brushed my teeth thoroughly, there would be no problems.
However, I brush my teeth manually every night, use dental floss, a water flosser, an electric toothbrush, and mouthwash, yet my gums still hurt when I eat.
On September 20, I deliberately ate using that area of my teeth despite the pain, cleaned my teeth afterward, and then used a flashlight to examine the area.
I discovered a horizontal crack in the middle of the gums, with the upper part appearing whitish.
Previously, when I used dental floss in that area, it would occasionally bleed, but recently, when using dental floss (with intentional increased pressure), in addition to the severe pain, the bleeding has decreased significantly (light orange).

Hello: When using dental floss, it is recommended not to apply too much force to avoid causing injury.
You may apply a small amount of oral ointment to the uncomfortable gum area.
If there is no improvement after 1 to 2 weeks, it is advisable to visit a medical center for further examination.

Gum pain when eating can be a frustrating and concerning symptom, especially when it persists despite regular dental care. Based on your description, it seems that you have been experiencing localized gum pain for several years, particularly when consuming certain foods like nuts. You have also mentioned that your dental check-ups have not revealed any significant issues, which can be disheartening when you are experiencing discomfort.

First, it’s important to understand that gum pain can arise from various causes, including gum disease, food impaction, or even issues related to the teeth themselves, such as cracks or cavities that may not be immediately visible. Given that you have been diligent with your oral hygiene routine—using dental floss, an electric toothbrush, and mouthwash—it's clear that you are taking steps to maintain your dental health.

The fact that you notice improvement after using dental floss suggests that food particles may be getting trapped between your teeth and gums, leading to inflammation and pain. However, if the pain persists even after cleaning, it may indicate a deeper issue. The presence of a horizontal crack in your gum tissue, as you described, could be a sign of a periodontal problem or a reaction to trauma from aggressive cleaning. The white coloration at the top of the gum may indicate tissue irritation or necrosis, which can occur due to chronic inflammation or infection.

Here are some potential explanations and recommendations for your situation:
1. Periodontal Disease: Even if your dentist has stated that your gums appear healthy, it’s possible that you may have early-stage gum disease (gingivitis) that is not yet fully diagnosed. Symptoms can include localized pain, swelling, and bleeding. A thorough periodontal evaluation, including probing to measure gum pocket depths, may be warranted.

2. Food Impaction: If certain foods consistently cause pain, it may be due to their shape or texture, which can lead to food getting lodged between teeth. Consider avoiding these foods or modifying how you consume them (e.g., chopping nuts into smaller pieces).

3. Aggressive Cleaning: While maintaining good oral hygiene is crucial, using excessive force when flossing or brushing can damage gum tissue. It’s essential to be gentle and use proper techniques. You might benefit from a consultation with a dental hygienist who can demonstrate effective cleaning methods.

4. Cracked Tooth Syndrome: If the pain is associated with a specific tooth, it could be due to a crack in the tooth itself, which may not be visible on X-rays. This condition can cause pain when chewing or when the tooth is exposed to temperature changes. A dentist may need to conduct further tests, such as a bite test, to diagnose this.

5. Referral to a Specialist: If your symptoms persist despite regular dental visits, consider seeking a second opinion from a periodontist or an oral surgeon. They may offer additional insights or treatments that a general dentist might not provide.

6. Home Care Adjustments: In the meantime, continue to practice good oral hygiene but consider using a softer toothbrush and being gentler with flossing. You might also want to try rinsing with warm salt water to reduce inflammation and promote healing.

7. Monitoring Symptoms: Keep a diary of your symptoms, noting when the pain occurs, what foods trigger it, and any other associated symptoms. This information can be valuable for your dentist or specialist in diagnosing the issue.

In conclusion, while it’s encouraging that your dentist has not found any significant problems, your ongoing symptoms warrant further investigation. By exploring these potential causes and adjustments, you can work towards alleviating your gum pain and improving your overall dental health. If the pain continues or worsens, do not hesitate to seek further evaluation from a dental professional.
