I went to their Chicago branch...The worst experience I have ever had in my life! From the front desk to Dr. Victoria Vahdani....Everything is horrible! I went there for my annual check up....I did not have any pain, but Dr. Vahdani suggested that I need to get a new crown.....she did an extremely bad job on the crown and after having pain in my gum for 2 months and going there back and forth to fix the problem, eventually I decided to go to another dentist....the new dentist told me that my gum is not even ready to get a crown and NOW I need gum lengthening!!!! REMEMBER I did not have any problem before going to PEARL DENTAL GROUP!!! I asked dr. Vahdani to sent my x-rays and give me refund!It took me several weeks to get my x-rays!!!
