I think you're right to have a second opinion. The only reason my oral squamous cell carcinoma was caught at all is because of a second opinion. I had been going to a dentist for 10 months who kept saying I had gingivitis and he kept extracting teeth. Finally got into a periodontist who immediately made the call, did a biopsy on the spot and it confirmed it. I will be faster in getting second opinions from now on.
