Owner & lead dentist
Dr. Gaganjot Khera, DDS — your lead dentist in Milpitas
Dr. Khera owns and leads Signature Smiles Dental Group, and she is the dentist most Milpitas patients see at every visit. She qualified twice — a Bachelor of Dental Surgery from Baba Farid University of Health Sciences in Punjab, then a Doctor of Dental Surgery from the University of Oklahoma — and brings 15+ years of clinical experience across family, cosmetic and restorative dentistry.
Patients describe her the same way in review after review: thorough, caring, and willing to explain what she is doing and why before she starts. She was named America’s Best Dentist in 2024, 2025 and 2026 — three years running.
Her day-to-day work spans preventive care, exams and cleanings through crowns, fillings and root canal therapy, and on to cosmetic work including Invisalign, veneers, take-home whitening and full smile makeovers. She also restores dental implants with the final crown.

Today · 440 E Calaveras Blvd, Milpitas
Owner and lead dentist, Signature Smiles Dental Group
Named America’s Best Dentist in 2024, 2025 and 2026 — and still the dentist you see at almost every appointment.
What that means in the chair
One dentist who has seen the whole range
Two dental degrees on two continents, two years spent assisting, and years of general practice across California before Milpitas. The practical result is a dentist who can take a child’s first cleaning and a full smile makeover in the same afternoon, and who has almost certainly already seen whatever you are about to describe to her.
She treats most cases herself — including root canal therapy and extractions — and refers out only when a specialist genuinely changes the outcome.

If the dentist makes you anxious
Nervous about dental visits? How your Milpitas dental team handles it
Plenty of our patients arrive having put a visit off for years. Nobody here is going to make you feel bad about that. Dr. Khera talks through what she sees, what she recommends, and what it will cost before anything begins — and she stops when you ask her to.
If you are in pain right now, call rather than book online. Same-day emergency dental appointments are held open for exactly this, and the front desk will fit you in.
Cost is the other reason people wait. We accept PPO dental plans from most major carriers, offer payment plans, and run an in-house dental membership plan for patients without insurance.

Where our patients come from
Dental care for Milpitas, Fremont, San Jose and Santa Clara
The office sits just off Calaveras Boulevard between I-880 and I-680, with a free lot outside — which is why a good share of the people Dr. Khera treats drive in from the neighbouring South Bay cities rather than from Milpitas itself.
- From Fremont I-880 or I-680 south · exit Calaveras Blvd Under 15 minutes outside of rush hour from Warm Springs, Irvington, Mission San Jose, Centerville, Niles and Ardenwood.
- From San Jose US-101, I-880 or CA-237 north · exit Calaveras Blvd Roughly 10 to 15 minutes outside of peak traffic from Berryessa, North San José, Alviso, Evergreen and Alum Rock.
- From Santa Clara US-101, CA-237 or I-880 · exit Calaveras Blvd Fifteen to twenty minutes outside of rush hour from Rivermark, the Old Quad and the Levi’s Stadium area — or the VTA Orange Line, if you would rather not drive.
