After reviewing your case, I want to reassure you that you are likely on a normal, albeit slow, healing path. The area between tooth 46 and 47 sits right next to your recent wisdom tooth extraction socket (tooth 48). When a wisdom tooth is removed, the surrounding gum tissue, bone, and structural support undergo significant remodeling.
The "cut" you felt 40 days ago was likely a localized injury to an already sensitive, healing interdental papilla (the gum triangular tip between teeth). Because you have already seen two dentists and an ENT, and your panoramic and periapical X-rays show no deep abnormalities, infection, or retained root fragments, we can confidently rule out serious pathology.
The dull, vanishing pain indicates the nerves are settling. The occasional bleeding you notice during brushing or poking occurs because the newly forming healing tissue (granulation tissue) is highly vascularized and fragile. Every time it is disturbed, it bleeds easily. Toothpastes alone do not heal cuts, but proper local management will.
Next Steps
To help this tissue mature completely and stop the bleeding, I recommend you implement the following steps:
Stop Probing the Area: I strictly advise you to stop checking or poking the gum with your finger or tongue. Continuous mechanical irritation restarts the healing clock and keeps the tissue fragile.
Modify Your Brushing Technique: Use an ultra-soft bristled toothbrush. When cleaning around teeth 46 and 47, do not scrub horizontally. Instead, use a gentle, sweeping motion away from the gums to avoid tearing the new tissue.
Introduce a Warm Saltwater Rinse: Discontinue aggressive commercial mouthwashes. Instead, rinse with warm saltwater (half a teaspoon of salt in a glass of warm water) 2 to 3 times a day, especially after meals, to keep the area clean and reduce local swelling.
Continue Your Current Supplements: I highly approve of your
Vitamin C and B_{12} regimen. Vitamin C is essential for collagen synthesis and gum repair, so keep taking them as prescribed.
Health Tips
Expect a Slow Timeline: It is normal for deep gum remodeling following a nearby extraction to take a few months to fully mature. Do not let this timeline cause you anxiety.
A Word on Food Biofilms: Make sure sharp foods like chips, nuts, or hard crusts are chewed on the opposite side of your mouth for the next few weeks to prevent physical micro-trauma to the healing site.
When to Re-evaluate: While your current X-rays are clear, if you develop throbbing pain, sudden swelling in your jaw, bad taste, or spontaneous bleeding that does not stop after a few minutes, please return to your dentist for a clinical re-check
