At Montague Hills Dentistry, Dr. Oscar Celis and Dr. Alejandro Celis pair advanced technology with a gentle, personal touch — creating healthy, confident smiles that last a lifetime. En español, también.
Montague Hills Dentistry is built around a simple idea — that great dentistry is personal. Since 2006, brothers Dr. Oscar Celis and Dr. Alejandro Celis have listened before they recommend and explained before they treat, bringing the latest technology to every appointment. From a routine cleaning to a full smile makeover, every visit in Milpitas, CA is shaped around you — and it happens in English or Spanish, whichever feels like home.
Every recommendation is one we’d make for our own family. If something can wait, we’ll tell you. If it can’t, we’ll explain why in plain language and show you exactly what we see on the screen.
From your first visit forward, Dr. Oscar and Dr. Alejandro look after your care personally. You’ll see familiar faces at every appointment, and your history stays with us — no starting over, no being passed around.
Ergonomic chairs, soft lighting, and a calm pace, with a movie, documentary, or music to pass the time. We schedule deliberately so no one ever feels rushed — your time in the chair should feel as considered as the work itself.
Regular checkups and cleanings are the foundation of a healthy smile. These preventive visits protect your teeth, gums, and jaw — catching small issues early, before they turn into bigger ones.
Care for every age, from a child's first visit to grandparents. (Yes — we're great with kids.) One practice and one trusted team for the whole family.
Brighten your smile with professional whitening, including Philips Zoom. It's a simple, quick treatment that lifts years of stains far beyond what over-the-counter kits can reach.
Straighten your teeth without wires or brackets. Dr. Alejandro Celis is a preferred Invisalign provider, using a series of clear, custom trays to gently guide your smile into place.
Our intraoral scanner captures your tooth digitally — no goopy impressions, no gagging. The result is a computer-designed crown, veneer, or implant crown that fits precisely and looks completely natural.
Replace missing teeth with permanent, natural-looking implants. With in-house CT imaging and bone grafting, we plan and place your implants with precision, from first scan to final tooth.
Four principles we built the practice around. Every visit flows from these.
From your first consultation to your final result, Dr. Oscar and Dr. Alejandro are your dentists. You'll get to know them, and they'll get to know your smile.
A calm suite, gentle technique, and a pace that never feels rushed. We make sure you understand what's happening, every step of the way.
Cleanings, cosmetic dentistry, Invisalign, implants, bone grafting, and oral surgery all happen in-house. You won't get bounced between offices for the care that matters most.
Great care shouldn't get lost in translation. We treat you — and explain everything — in the language you're most comfortable in.
If your question isn't answered here, contact us and we'll help.
