Our philosophy is simple: catching a small cavity at a routine exam is always better — and far less expensive — than treating an infected tooth months later. Prevention is the foundation of everything we do.
Signature Smiles Dental Group cares for patients of all ages across Milpitas and the South Bay, from a child’s first tooth through retirement. Our practice is led by Dr. Gaganjot Khera, DDS — named America’s Best Dentist in 2024 and 2025 — alongside a skilled team of hygienists who deliver thorough, gentle care and personalized hygiene coaching at every visit.

Preventive Services We Provide
Every routine and preventive need under one roof at our Milpitas office — from your child’s first visit to a senior parent’s quarterly maintenance appointment.

Fluoride Treatments & Dental Sealants
These are the two most effective cavity-prevention tools we offer Milpitas families — especially for children, but also for adults at higher risk. Both are quick, painless, and heavily covered for children by most PPO plans.
Fluoride Treatments
Strengthens enamel, repairs early decay.
- Professional-strength varnish painted on teeth
- Hardens enamel against acid attacks
- Repairs microscopic damage before it becomes a cavity
- Done in five minutes at the end of a cleaning
- Children: every 6 months, typically 100% covered
- High-risk adults: every 3–6 months
Dental Sealants
A physical barrier in deep molar grooves.
- Liquid resin painted into molar grooves
- Cured with light — painless, no drilling
- Stops food & bacteria getting trapped
- Best for ages 6–14 on new molars
- Also helps cavity-prone adults
- Lasts 5–10+ years; checked at every visit
Sealant vs. Filling
A small step today saves thousands later.
- Sealant: $30–$60 per tooth, painless, no drilling
- Filling: $150–$450 per tooth, anesthesia required
- Root canal + crown: $2,000–$3,500
- Every $1 on prevention saves $8–$50 later
- Children under 14: sealants typically 80–100% covered
Oral Cancer Screening at Every Exam
A quick, painless part of every preventive exam at our Milpitas office. More than 54,000 Americans are diagnosed with oral cancer each year, and early detection changes everything — it is one of the most valuable minutes of your dental visit.

- Red or white patches anywhere in the mouth

Home Care — The Other Half of Prevention
Professional visits at our Milpitas practice work best when paired with excellent daily home care. Our team provides personalized oral hygiene instruction at every visit — here is the foundation.
Proper Brushing
Twice daily, two minutes each time.
- Soft-bristled brush at a 45° angle to the gumline
- Gentle circular motions — never scrub
- All surfaces: outer, inner, chewing, and tongue
- Replace your brush every 3 months
- Electric brushes remove more plaque
Daily Flossing
Where most cavities & gum disease begin.
- Brushing cleans only about 60% of tooth surfaces
- Flossing reaches between teeth where decay starts
- Curve floss into a “C” shape around each tooth
- Slide gently below the gumline
- Water flossers are great for braces & bridges
What You Eat Matters
Small daily choices protect your enamel.
- Limit sugar — it feeds cavity-causing bacteria
- Limit acidic drinks — soda, sports drinks & citrus erode enamel
- Drink water to rinse away bacteria and acids
- Dairy & crunchy vegetables strengthen and clean
- Tobacco multiplies gum disease risk 6–7×
