Noble Smile Family and Cosmetic Dentistry

Award-Winning Advanced Dentistry, Exceptional Dental Care

Noble Smile Family and Cosmetic Dentistry


When Noble Smile Family and Cosmetic Dentistry opened in Katy a decade ago, the community immediately embraced Dr. Allen Jahangiri’s unique brand of personalized, high-quality, comprehensive dental care. He quickly became one of Greater Katy’s most respected, best-loved dentists and has maintained this status ever since. One look at his 500+ perfect five-star Google reviews says it all, telling a story of exquisite dentistry and patient care at a level of excellence that’s difficult to find.

Noble Smile has continually been voted top in its field by patients and their peers. Noble Smile has received Living Magazine’s Best Of Katy/Fulshear Family/Cosmetic Dentist awards four years running. The Consumers’ Research Council of America named Dr. Jahangiri one of America’s Top Dentists for seven consecutive years. And again, this year, the practice won Best Dentist in “Houstonian Magazine.”

Dr. Jahangiri has steadily expanded his practice over the years. Today, it includes three dentists — Dr. Jahangiri and two talented associates, Dr. Moiz Hemani, who went to dental school with Dr. Jahangiri, and Dr. Preston Gray, who recently joined the team. Visiting dentist Dr. Roscoe Foust performs IV sedation and oral surgery as needed. And now, as the practice celebrates its 10th anniversary, the office space is expanding to continue to keep pace with a growing community.

“We’re growing the practice to accommodate new patients and continue to offer the highest standard of patient care,” says Dr. Jahangiri. “I’m especially proud of our team who help make it all possible. Most have been with me for years, and patients enjoy seeing the same friendly, familiar faces at each appointment. Everyone welcomes patients like family, helps them feel comfortable, and does everything possible to help them leave happy. We also educate our patients and provide options, so they feel confident in their dental decisions.”

Dentistry With a Difference

Everyone deserves a sparkling, bright, healthy smile. Dr. Jahangiri and his team want to help you achieve this and enjoy the advantages, including the hidden benefits to your overall health. They start by offering almost all the services you and your family could need, from routine preventive care to complex smile rehabilitation. The high-tech office boasts a range of advanced technologies, including a 3D cone beam CT and intraoral scanner combination with 3D printing, digital radiographs, and an OralID handheld cancer-screening device.

“It’s a fun time to be a dentist with all of the new technology and materials available, but it requires absolute dedication to continual learning and continuing education,” Dr. Jahangiri comments.

Dr. Jahangiri expertly combines science and artistry to create highly customized smile makeovers. Using a conservative approach and advanced technology, his goal is to retain as much of the natural tooth structure as possible. As a Gold Plus Invisalign provider with 13 years of experience, he combines services such as Invisalign and teeth whitening to create gorgeous, natural smiles. In cases where he uses porcelain veneers, he adheres to his conservative, minimal-preparation philosophy.

Your smile is the most beautiful thing you can wear every day,” Dr. Jahangiri shares. “Helping patients achieve a healthy, attractive smile is immensely gratifying.” 

With dental implants, Dr. Jahangiri’s attention to detail, use of 3D CBCT imaging for planning, and image-guided-surgery techniques help ensure natural-feeling, fully functioning teeth.

Finally, the Noble Smile dentists not only detect oral cancer but can spot oral health issues that may indicate disease elsewhere in the body, such as Type 2 diabetes or cardiovascular disease.

Get to Know the Noble Smile Dentists

After earning his DDS at the University of Texas Health Science Center in San Antonio, Dr. Jahangiri completed an extensive postgraduate residency to master numerous advanced techniques and procedures. Passionate about continuing education in advanced dentistry and investing in groundbreaking dental technology, he travels worldwide to learn from the foremost innovators in dental techniques, technologies, and materials.

When he’s not busy seeing patients, Dr. Jahangiri loves traveling, exercising, and spending time with his family. He and his wife, Nooshin, who is a pharmacist, are the proud parents of a seven-year-old son and three-year-old daughter.

Dr. Moiz Hemani enjoys establishing long-term relationships with his patients and working with a great team. He received a Bachelor of Science in microbiology and immunology at the University of Texas, Austin, and attended dental school with Dr. Jahangiri at the University of Texas Health Science Center at San Antonio Dental School. Having grown up in Sugar Land, Dr. Hemani returned home to practice in the Katy, Richmond, and Sugar Land area. In his free time, he loves traveling and spending time with his family.

Dr. Preston Gray, who has lived in Fulshear for 10 years, is passionate about providing individualized, state-of-the-art dentistry to the community in a family atmosphere. After earning his bachelor’s degree from the University of Houston, he completed his DDS at the University of Texas School of Dentistry at Houston.
