About Gentle Family Dentistry Center for Implants & Facial Aesthetics
An 8-month Invisalign timeline, compared to a quoted two-year estimate elsewhere, is the kind of result reviewers credit to Dr. Riyaz K. Gangji and Dr. Lucas Mantilla.
This general dental practice also offers Invisalign, traditional braces, and clear aligners, with Invisalign drawing notably more attention here than typical dental offices. Reviews mention accelerated treatment timelines, teeth shifted after skipped retainers being corrected, and Dr. Gangji personally following up on Invisalign pricing and progress. Cosmetic and restorative work, including dentures, veneers, and implants, is also called out for strong outcomes, and the office is described as modern with AI-assisted diagnostics.

Gentle Family Dentistry is the absolute best, if you need work or are worried please don’t hesitate to visit this office, i hadn’t gone to a dentist in years and being new to the area i didn’t know where to go and i found them, and they take care of any concerns you have work with you with pricing, follow up and go step by step and do great work, i am happy to smile again and continue getting work done on my teeth with reliable professionals at an affordable price! Thank you Dr. Nik Patel and his dental assistant Maria, together they made my experience getting two route canals and fillings on my front teeth painless and fast!
Very friendly caring willing to explain in detail you work that needs to be. You know what your charge is, before your work is done. Love their process.
