How Do They Achieve This?
With its unique blend of high-touch and high-tech care, Noble Smile has earned more than 1,300 perfect five-star Google reviews, making it Katy’s top-rated cosmetic and Invisalign dentist. The practice has also been voted Best Of numerous times in Living Magazine’s Readers’ Choice awards, including Best Family Dentist in 2023.
Dr. Allen Jahangiri, founder and president of Noble Smile, has been practicing dentistry since 2008. Along with his team, he offers pristine dental care and aesthetic procedures to give you the smile you truly deserve. Over the years, Dr. Jahangiri has carefully built a team of talented professionals who share his commitment to excellence.
“We’ve grown to accommodate new patients while continuing to provide the highest standard of care,” says Dr. Jahangiri. “I’m excited to share my practice with the area’s finest and most respected dentists.”
Meet the Team
Dr. Preston Gray, a Fulshear resident for 13 years, is dedicated to providing state-of-the-art, individualized dentistry in a family-friendly environment. After earning his bachelor’s from the University of Houston, he completed his DDS at the University of Texas School of Dentistry in Houston.
Dr. Safarzadeh’s journey into dentistry began in high school when he shadowed a dentist and discovered his passion for helping others. In addition to his clinical practice, Dr. Safarzadeh is a part-time instructor at multiple dental schools, including UTHealth Houston School of Dentistry.
Dr. Karen Khan, with a background in cosmetology and a deep passion for art and medicine, was drawn to dentistry as it perfectly blends science and aesthetics. As a graduate of Case Western Reserve School of Dental Medicine, she’s committed to enhancing her patients’ smiles, knowing the profound impact it can have on their self-confidence.
Dr. Roscoe Foust joined Noble Smile to provide expert surgical services in a comfortable, patient-centered environment. He specializes in IV sedation and oral surgery, ensuring a smooth experience for patients undergoing these procedures.
Most team members have been with Noble Smile for years, creating a sense of familiarity that patients appreciate. “Our patients are like family to us,” says Dr. Jahangiri. “We want them to feel at home in our office and leave with a smile.”
Advanced Care, State-of-the-Art Technology
Noble Smile offers a full range of oral and aesthetic healthcare services, from routine preventive care to complex smile makeovers, all delivered with cutting-edge technology. Whether it’s maintaining oral health or creating a brilliant smile, the team believes everyone deserves the confidence that comes with good oral care.
“Your smile is the most beautiful thing you’ll ever wear,” says Dr. Jahangiri. “That’s why we do what we do — to help our patients achieve their best smile.”
Combining science with artistry, the team at Noble Smile crafts highly customized smile makeovers using a conservative approach, preserving as much of the natural tooth structure as possible.
With over 14 years of Invisalign experience, Dr. Jahangiri is recognized as a Platinum Invisalign provider. “With our AI technology, patients can see a preview of their before-and-after smile in the same visit,” he says. “You’ll know your results before we even start treatment.”
For those opting for porcelain veneers, Dr. Jahangiri follows a minimal-preparation philosophy. In the case of dental implants, he uses 3D CBCT imaging and image-guided surgery techniques to ensure natural-looking, fully functional results.
Invisalign and teeth whitening can also be combined to create stunning, natural smiles.
A Comprehensive Approach to Dental Health
Noble Smile takes a whole-body approach to dentistry. Their dentists can detect oral cancer and spot potential health issues, such as Type 2 diabetes and cardiovascular disease, during routine exams. They also screen for sleep apnea, even conducting sleep studies in the office to help identify and treat this condition, which can lead to other systemic health problems.
“We educate our patients and provide options,” says Dr. Jahangiri. “That way, they feel empowered to make informed decisions about their dental care. Even anxious patients can relax knowing that we offer nitrous oxide, oral conscious sedation, and IV sedation if needed.”
The practice’s use of advanced technology includes digital radiography, which provides far greater accuracy than traditional X-rays. They also utilize the iTero intraoral scanner and infrared scans, which can sometimes detect cavities without the need for X-rays.
“We also use AI to review our X-rays alongside us,” adds Dr. Jahangiri. “AI not only serves as a powerful diagnostic tool, double-checking our work to ensure accurate diagnosis, but also acts as a visual aid for our patients, helping them better understand their diagnosis.”
