Your New Dentist in Walnut Creek
If you live in Walnut Creek, you probably had that moment when a tooth starts hurting right in the middle of your day — maybe after lunch at Broadway Plaza, or when you’re dropping kids off at Northgate High, or while you’re walking around Heather Farm Park. It’s stressful, and most folks don’t know who to call first. This is why many families around Castle Hill, Ygnacio Valley, and Shadelands come to our office. Our team tries to make dental care simple, calm, and real.
When people ask, “Who’s a good Dentist in Walnut Creek, CA?” our name pops up a lot because we talk to people in plain words, we fix small problems early, and we help with tough ones too. We’ve lived and worked around Walnut Creek a long time, so we know the small things that matter — the dry summer air that bothers gums, the cracked teeth from sports at Arbolado Park, and the night-grinding from long commutes on 680.
Below you’ll see all the care we offer. The language is simple, so anyone can read it. But the skills behind it are backed by years of doing this work, every day, with neighbors just like you.

Our Services
Emergency Dental Services in Walnut Creek, CA
Toothaches don’t wait for a good time. If you chip a tooth while eating lunch in downtown Walnut Creek, or your child gets hit during sports at Heather Farm Park, or you wake up with a swollen gum — you need help now.
We offer same-day emergency appointments for pain, infection, broken teeth, lost crowns, injuries, or anything that feels scary.
Call us early in the day for fastest help.
Orthodontist in Walnut Creek, CA
Walnut Creek families come to us when they want straighter teeth or a better bite. Kids, teens, and many adults choose braces or clear aligners because they want a smile that feels right and looks natural.
We start with a simple talk about what bugs you — maybe crowded front teeth, a bite that doesn’t feel right, or a smile that looks uneven. Then we check the jaw, spacing, and alignment. We help plan braces or aligners that fit your day-to-day life, even if you have a busy schedule running between school events, gym stops, and errands.
Fast Braces
Fast Braces use advanced technology to move teeth more efficiently, often completing treatment in just months instead of years. It’s an ideal option for patients seeking faster results with less discomfort.
Invisalign®
For a nearly invisible and flexible alternative, Invisalign® is a favorite among adults and teens in Walnut Creek. We take precise digital scans—no messy molds—to create a treatment plan tailored to your lifestyle. Many of our Downtown Walnut Creek patients love that they can remove their aligners for meetings, meals, or special occasions without worry.
Pediatric Dentist in Walnut Creek, CA
Kids need simple, gentle care. We see children from local schools and daycares around Walnut Creek — Bancroft Elementary, Walnut Acres, and families living near Heather Farm.
We help kids feel safe. We use simple words, show them tools before using them, and keep visits short. Our goal is to help kids grow up without fear of the dentist, so they stay healthy as adults.
Children’s Dentistry
Parents in Rossmoor and Ygnacio Valley appreciate our gentle approach, child-sized instruments, and plenty of encouragement at every visit.
We offer:
Routine cleanings and fluoride treatments
Sealants to protect baby and adult teeth
Fun education on brushing and flossing
Cavity repair and early orthodontic checks
Every child leaves with a big smile—and a special prize from our treasure chest!
Cosmetic Dentist in Walnut Creek, CA
Many patients want a smile that feels bright and natural. Our cosmetic care helps with chips, stains, uneven shapes, or old fillings that look dark. We offer whitening, bonding, veneers, and small fixes that make a big visual difference.
We talk about what YOU want first. Some people want tiny changes. Others want a full makeover. There’s no pressure — we just give choices that fit your goals.
Cosmetic Dentistry
Popular options include:
Teeth whitening for stains or discoloration
Veneers to correct chips, gaps, or uneven shapes
Dental bonding for quick, affordable touch-ups
Smile design consultations with Dr. Khandaqji
Many patients visit us before major life moments—like weddings, interviews, or reunions. Our goal is to help you feel confident and radiant with a natural-looking, healthy smile that shines in every setting.
Endodontist in Walnut Creek, CA
Tooth pain can hit fast. Lots of people wake up with a sharp ache running into the jaw or feel a sting when drinking cold water. That deep ache often means the inside of the tooth — the nerve — is hurt or infected. Our endodontic care helps stop that pain.
We clean the inside of the tooth, remove bacteria, and seal it so the tooth can stay in your mouth. Many root canal cases come from folks near Walnut Heights and the Iron Horse Trail area. They walk in worried, but they walk out relieved because the pain finally stops.
If you feel that pressure pain that won’t go away, call us.
Early care helps save the tooth.
Periodontist in Walnut Creek, CA
Gums stay quiet—until they don’t. Bleeding when brushing, swelling around back teeth, or that “sore when I chew” feeling can mean gum disease is starting. Our periodontal care helps treat gum issues early and stop them from spreading.
We clean deep below the gumline and remove the bacteria that like to hide there. And we talk about daily habits that help the gums heal. Walnut Creek weather swings, from hot summer dryness to cooler winter days, can make gum care harder for some people, so we help adjust your routine too.
Gum (Periodontal) Care
Our periodontal treatments are designed to reverse early gum issues and manage advanced cases with precision and comfort. We provide:
Deep cleanings (scaling and root planing)
Ongoing gum maintenance therapy
Laser-assisted gum treatment
Education on at-home care and brushing techniques
Prosthodontist in Walnut Creek
When teeth break, wear down, or go missing, simple chewing becomes hard. We help restore full smiles using crowns, bridges, dentures, and implant-supported replacements.
People from all over Walnut Creek — Saranap, El Dorado Hills, Walnut Heights — come to us when a tooth breaks on a popcorn kernel or a molar cracks during a weekend at home. We match the new tooth to your natural look and make sure the bite feels good.
You’ll be able to smile and eat without thinking about the missing spot.
Oral Surgeon in Walnut Creek, CA
Sometimes a tooth grows sideways or gets stuck, like wisdom teeth do. Or maybe you chipped a tooth during sports or had an accident on the bike trails near Shell Ridge. Oral surgery handles those more complex cases.
We remove impacted teeth, fix jaw pain, take out broken teeth, and do other surgical treatments that need special skill. We work gently and explain things step by step, especially for patients who feel nervous.
You’ll always know whats going on and why.

- Teeth Exam and Cleaning
We do simple cleanings and check-ups to remove plaque, check gum health, and catch small problems early. Most people come twice a year.
- 3D Imaging
We use 3D scans to see your teeth, roots, and bone clearly. This helps with implants, root canals, extractions, and other advanced treatments.
- Oral Cancer Screening
We check the tongue, cheeks, gums, and throat for early signs of cancer. It only takes a few minutes and helps spot problems early.
- Tooth Extractions
We check the tongue, cheeks, gums, and throat for early signs of cancer. It only takes a few minutes and helps spot problems early.
- Fluoride Treatment
Helpful for kids and adults with weak enamel. Fluoride strengthens the surface of the tooth so cavities form slower.
- Dental Sealants
Thin, protective layers placed on back teeth. They help kids avoid cavities in the “chewing grooves” where food gets trapped.
- Night Guard for Teeth Grinding
If you wake up with jaw soreness or headaches, you might be grinding at night. A custom guard helps protect the teeth.
- Periodic Oral Examination
We check the mouth regularly for changes in teeth, gums, bite, and soft tissues. Helps catch small issues early.
- Guided Biofilm Therapy
A gentle cleaning method that removes plaque and bacteria using modern tools. Feels softer than older cleaning methods.
- Sedation Dentistry
For people who feel nervous, we offer sedation options that help calm the body and mind so treatment feels easier.

- Knocked-out tooth: Put it in milk and come here fast.

Dr. Mohammad Khandaqji is an excellent doctor. He made me feel extremely comfortable while having my wisdom teeth removed. He would make sure I wasn’t feeling any pain and if I did he would stop and add more local sedatives immediately. He and the nurse helped me not feel anxious about the procedure and made me feel like I was in trusted hands at all times. I would definitely recommend him to anyone needing any dental procedure.
