Hi,
Your history is classic for Cracked Tooth Syndrome / Cracked Cusp in the tooth next to wisdom tooth (usually lower 2nd molar). This is very common when there is distal caries due to wisdom tooth.
Why I say cracked tooth:
1. Sudden sharp pain on biting something hard
2. Pain ONLY on biting at a specific angle, and goes away instantly on releasing bite - this is the hallmark of a crack
3. Percussion test (tapping) is normal - because root is normal, crack is in crown
4. Pain persisting even after GIC filling and bite adjustment
5. X-ray is usually normal in cracked tooth - so decay may look less deep clinically
Removal of wisdom tooth was correct, but the 2nd molar that was in contact likely had a micro-crack already from before.
Next Steps (Very Important):
1. Please upload a clear present IOPA X-ray of the filled tooth.
2. Your dentist needs to do: Tooth Slooth / bite test, Transillumination test, and Staining test to confirm crack. CBCT does NOT show crack well.
3. Do NOT go for RCT immediately unless crack extends to pulp. Many cracked teeth are saved by a crown / overlay only.
Helpful Tips:
1. Avoid chewing hard from that side till diagnosis is confirmed - crack can propagate.
2. Avoid very cold / very hot food if it triggers pain.
3. If pain is exactly on biting and release, you need a full coverage crown with proper occlusal protection, not just a GIC filling. GIC is weak and will not hold a cracked cusp.
4. Visit an Endodontist for cracked tooth evaluation - they have special tools (microscope, tooth slooth) to confirm.
If you can tell me - is pain more on biting hard food vs soft food? And does cold water cause sharp pain for few seconds?
Share your X-ray here, I will guide you if you need crown or RCT + crown.
Hope this helps.
