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.

Fluoride & Sealants

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.

25–40% Cavity Reduction

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
Up to 80% Cavity Reduction

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
Prevention Always Wins

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

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.

At-Home Habits

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.

Most Important Step

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
Cleans the 40% Brushing Misses

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
Diet & Lifestyle

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×
Cost & Value

Why Prevention Is Always Worth It

The financial case for preventive care in Milpitas is clear: every dollar spent on prevention saves eight to fifty dollars in restorative treatment. Here is what catching a problem early versus late actually costs.

Caught Early at a Preventive Visit

  • Cavity caught early $150–$250 filling
  • Gingivitis caught early $100–$200 cleaning
  • Crack spotted early $1,100–$1,500 crown
  • 2 cleanings + 2 exams / yr $400–$800 total
  • Most PPO insurance covers 80–100%

Ignored Until It Hurts

  • Deep decay $2,000–$3,500 root canal + crown
  • Advanced gum disease $2,000–$8,000 surgery
  • Cracked tooth not caught $150–$600 extraction
  • Tooth loss $3,000–$6,000 implant
  • Multiple teeth lost $15,000–$40,000+ rehab

Questions & Answers

Preventive Dental Care — FAQs

Common questions about preventive visits, coverage, and home care at our Milpitas dental office.

What preventive dental services does Signature Smiles offer in Milpitas?
We provide comprehensive preventive care at 440 E Calaveras Blvd including professional cleanings, comprehensive exams, digital X-rays with Pearl AI, fluoride treatments, dental sealants, oral cancer screenings, periodontal assessments, and custom mouth guards. We care for all ages from infants through seniors. Call (408) 946-0777 to schedule.
How often should I visit the dentist for preventive care?
Most patients in Milpitas benefit from a visit every six months — two cleanings and two exams per year. Patients with active gum disease, high cavity risk, diabetes, or dry mouth typically need visits every three to four months. We customize your recall schedule based on your individual risk profile.
Does dental insurance cover preventive care?
Yes — preventive care is the best-covered category in most PPO plans. Two cleanings, two exams, routine X-rays, and fluoride for children are typically covered at 80–100%, often with no deductible. We accept Delta Dental, Guardian, Aetna, Humana, and most PPO plans. We verify your benefits and file all claims for you. Visit our insurance page.
What is the difference between a routine cleaning and a deep cleaning?
A routine prophylaxis cleaning is for patients with healthy gums — it removes tartar above and at the gumline, takes 45–60 minutes, and needs no anesthesia. A deep cleaning (scaling and root planing) is a therapeutic procedure for patients with gum disease — it cleans inside periodontal pockets under local anesthesia over two to four appointments. We recommend only what your gum health actually requires.
Are dental X-rays safe?
Yes. Our digital X-rays emit up to 90% less radiation than traditional film. A full set of bitewing X-rays exposes you to roughly the same radiation as a few hours of normal background sunlight — far less than a chest X-ray or a cross-country flight. We use lead aprons and thyroid collars as added precautions. Please tell us if you are or may be pregnant so we can take extra care.
What are dental sealants and who needs them?
Sealants are thin protective coatings applied painlessly (no drilling) into the deep grooves of back molars, reducing cavity risk by up to 80%. They are most beneficial when first molars erupt around age 6 and second molars around age 12. Cavity-prone adults with deep grooves and no existing fillings in those grooves can also benefit. For children under 14, sealants are typically 80–100% covered by PPO insurance.
Do I really need to floss if I brush well?
Yes — daily flossing is essential. Brushing cleans only about 60% of tooth surfaces; flossing cleans the other 40% between teeth, exactly where most cavities and early gum disease begin. Water flossers are an excellent alternative for patients with bridges, implants, or orthodontic appliances. See our flossing guide for proper technique.
Is preventive care different for children versus adults?
The core services are the same, but the focus shifts by age. Children benefit most from fluoride every six months (typically 100% covered), sealants on new molars, and X-rays to monitor development. Adults focus more on gum disease screening, oral cancer screening, monitoring existing restorations, and managing risk factors. Learn more on our pediatric dentistry page.
Do you accept new patients and offer Saturday appointments?
Yes — we are accepting new patients of all ages across Milpitas and offer Saturday appointments (9am–6pm) along with weekday hours, which makes it easy to schedule a cleaning or exam around work and school. We verify your insurance benefits before your first visit and file all PPO claims for you. Call (408) 946-0777 or book online to get started.
