Expensive and unnecessary surgery

Was referred by my dentist, who said one tooth was resisting resolution for my pocket depth (she said it had a pocket depth of 7mm). Dr Wiesen tested my pockets and found, just 2 weeks after my dentist's exam, that I had several 6s and 7s, and due to my ""moderately aggressive periodontitis"" I was a candidate for immediate osseous (gum) surgery, with bone grafts.

Had the surgery, found out that it left huge gaps between my teeth. Dr Wiesen not only said this was normal but that it was a good thing.

Saw 2 other dentists after this, one of whom is a respected periodontist who teaches at UCSF and has been published numerous times in periodontal journals. BOTH said my gums were fine, with mild, easily treatable (without surgery) periodontitis and that surgery was completely uncalled for.

I now have gaping holes between my teeth on one side, that trap food and require additional care. As for my pockets? THEY'RE THE SAME on both treated and untreated sides! I'm not joking. The surgery was only done 2 months ago.

I spent over $4000 for unnecessary treatment that has effectively made my gum condition worse. Caveat emptor!
