Award-winning Noble Smile Family and Cosmetic Dentistry is one of Greater Katy’s most-respected, best-loved dental practices. Owner and Founder Dr. Allen Jahangiri and his team go above and beyond to provide a level of dentistry and patient care that sets them apart.

Proudly serving the community with advanced, comprehensive dentistry for more than a decade, Dr. Jahangiri continues to evolve and expand the practice to best serve their patients. It’s no wonder the Noble Smile Family and Cosmetic Dentistry is frequently voted top in their field by peers and patients alike.

“We recently finalized our office expansion to offer the highest standard of care to more patients,” says Dr. Jahangiri. “I’m especially grateful for our high-caliber team, including Drs. Moiz Hemani and Preston Gray, who welcomes patients like family and strives to provide an unparalleled level of customer service seamlessly combined with advanced dentistry.”

Exceptional Dentistry, Patient Convenience

The Noble Smile team offers most patients all the services they need in one practice, from routine preventive care to complex smile rehabilitation. At the forefront of dentistry, the practice uses the latest technologies, including 3D cone beam CT, intraoral scanners, 3D printing, and digital radiographs. An OralID handheld cancer-screening device helps them detect oral cancer and spot oral health issues that may indicate the presence of disease elsewhere in the body.

Science and artistry are expertly blended to create highly customized smile makeovers. Taking a conservative approach, Dr. Jahangiri believes in minimal preparation when appropriate to retain as much of the natural tooth structure as possible.

As one of only a few Gold Plus Invisalign providers in the area and with 14 years of experience, Dr. Jahangiri handles multiple Invisalign cases each week. Services like Invisalign and teeth whitening are frequently combed to create beautiful, natural-looking smiles.

Regarding dental implants — the gold standard for replacing missing teeth — the dentists use 3D CBCT imaging for planning and image-guided-surgery techniques for accurate placement to help ensure your implants feel natural and function smoothly.
