I almost completed my treatment with Dr. Amal. I find her thoroughly, attentive, and overall a pleasure to deal with. I highly recommend this practice.

Had a procedure here done today , there were no after care instructions . Not informative. Seemed quick to brush off , not even pictures of before or after were provided. I wouldn’t recommend, especially after paying a high amount . Really disappointed .

If you’re looking for the best orthodontist in the DFW area, look no further than Dr. Seif at Castle Hills 3D Orthodontics. I cannot overstate how grateful I am to have found her after a long and frustrating search.

Before landing in Dr. Seif’s care, I visited most of the major orthodontic and dental chains across the metroplex—Ideal Dental, Mint, you name it. Every single one of them told me the same thing: in order to fix my overcrowded teeth and overbite, I would need to have two perfectly healthy teeth removed. The rationale? “It’s the only way to make room.”

As someone who values long-term health and had done extensive research, I knew that tooth extraction for orthodontic purposes—especially in adults—can lead to potential long-term issues like compromised jawbone structure, facial profile changes, and even airway problems. I wasn’t comfortable accepting that as my only option. So I kept looking.

That’s when I found Dr. Seif.

She was the only orthodontist who believed my complex case could be corrected without extractions. From day one, she treated my case with a level of precision and customization that immediately set her apart. Over the course of 18+ months, she developed a plan tailored just for me, using Invisalign in combination with a Carriere Distalizer to gradually shift and open space—all while preserving every single tooth.

The level of care didn’t stop there. Midway through treatment, I had to get a root canal and crown. Dr. Seif seamlessly coordinated with my general dentist to ensure the process went smoothly and my ortho treatment stayed on track. Her attention to detail and collaboration across providers gave me confidence that I was in the best possible hands.

Today, I have the smile I’ve always wanted—and I didn’t have to sacrifice any of my natural teeth to get it.

And get this—I drive 45 minutes each way to her office. That’s how worth it this experience has been. If you’re shopping around for an orthodontist or have been told that tooth extraction is your only path to a better smile, please see Dr. Seif first. She’s not only incredibly skilled and knowledgeable, she’s compassionate, patient, and genuinely committed to doing what’s best for her patients long-term.

Don’t trust general dentists or high-volume chains to handle something as important and personal as your smile. Go to a true expert. Go to Dr. Seif.

Beware of the misleading “free consultation” — and pushy treatment recommendations.

We visited this clinic for our child’s dental consultation after seeing it was advertised as free. While the visit itself didn’t cost anything, what followed was extremely disappointing.

The dentist was adamant that our child needed to get his adenoids and tonsils removed and insisted we see a specific ENT she recommended — someone we later looked up and found to have very poor reviews. It felt like we were being rushed into a serious medical decision without exploring all options.

When we asked for a copy of our child’s X-rays to get a second opinion, they refused — unless we paid $300. Even though we offered to pay a reasonable fee for just the images showing the adenoids and tonsils, they still said no and stopped responding. They claimed they “care about our child,” but their actions said otherwise.

We’ve been to other clinics in DFW, including ones offering free consultations, and never experienced this kind of behavior. Other places have willingly shared X-rays upon request — because parents have a right to their child’s medical information.

If you’re thinking of going here, be cautious. Ask upfront about costs, access to records, and who they might refer you to — especially if it feels like they’re pushing you toward a specific provider. This experience felt more like a sales funnel than true patient care.

I had a wonderful experience with Dr. Amal seif who treated my daughter. She helped her stop thumb-sucking with a simple and effective solution. My daughter felt very comfortable with her — she’s not only skilled but also incredibly kind and patient. She explained everything clearly and answered all of our questions. I’m truly grateful for her care and highly recommend her 👍🌷
