Updated: July 9th, 2026 I initially had high hopes for my treatment, but my experience changed significantly. During treatment, I developed severe tongue pain and oral lesions that ultimately required evaluation and a biopsy by an oral pathologist. After discontinuing the aligners, my symptoms improved. When treatment was restarted, my mouth pain returned. I have reached out to the office multiple times regarding my symptoms and my request for a refund. I also hand-delivered supporting documentation to the office on July 7, 2026. Unfortunately, I have not received a meaningful response to my concerns or to my refund request. My review is based on my personal experience with the treatment, the communication, and the follow-up care I received. I was disappointed by the lack of responsiveness, particularly given the urgency of my symptoms. Update: 6/27/26 I rarely leave negative reviews, but I feel it's important to share my experience. My teeth looked great when my treatment was completed, so I was initially very happy. Unfortunately, the retainers caused significant pain from the beginning. I repeatedly told the orthodontist and the staff that something didn't feel right and that the retainers were hurting my mouth, but I felt my concerns were dismissed. I continued trying to wear the retainers on and off for about eight months because I trusted the treatment plan. During that time, I developed black patches throughout my mouth and an extremely inflamed, painful tongue. Since my symptoms continued to worsen, I sought care from an oral pathologist at my own expense. I paid approximately $2,200+ out of pocket for the pathology evaluation and testing, which ultimately determined that I was allergic to the material used in the retainers. After I stopped wearing the retainers for about a month, my mouth returned to normal. Hoping to finally complete my orthodontic treatment, I returned for retreatment. Unfortunately, after the new brackets were placed, my mouth and tongue became severely painful again. Within a day, the pain was so intense that I went to urgent care to have the brackets removed. In total, I have spent approximately $4,000 on orthodontic treatment, in addition to the $2,200 I paid for the pathology evaluation. While I understand that complications can happen in any medical or dental treatment, what disappointed me most was feeling that my concerns were not taken seriously until I had to seek answers from another specialist. I hope this review encourages the practice to listen carefully when patients report persistent pain or unusual reactions. Being heard early could spare someone else months of discomfort, unnecessary medical expenses, and emotional stress. Best Orthodontist! She's responsive and answers all my questions. My turned tooth is now in place in less than a year. I recently completed my Invisalign treatment. I couldn’t be more satisfied with the results. From start to finish, the entire process was smooth, professional, and personalized to my needs. Thanks to their expertise and care, my teeth look amazing, and I feel so much more confident in my smile. If you're considering Invisalign, I highly recommend Dr. Amal Seifelnasr and their team—you’ll be in excellent hand
