A gentle dentist puts your comfort first: making sure you are fully numb before treatment, moving at a calm pace, explaining what will happen, and pausing whenever you need. Gentle care is especially helpful for people with dental anxiety, sensitive teeth, children, and anyone who has had a hard visit before.
At Sigma Dental Clinic on W Foster Ave in Lincoln Square, Dr. Sepi Dashti, DMD, DDS, has more than 15 years of experience. Our team speaks English, Farsi, Spanish, Russian, Ukrainian and Romanian, so you can ask questions in the language you are most comfortable with. If dental visits make you anxious, read our guide for nervous patients.
How it works
01
Tell us what worries you. We listen, answer your questions and agree on a hand signal you can use to pause at any time.
02
We numb the area and check that you are fully numb before we begin. If you feel anything, tell us and we will add more.
03

04
Take a break whenever you need one. You leave with clear post-operative instructions and a number to call with any question.

I had a wonderful experience at Sigma Dental Clinic. Having not seen a dentist for many (many) years, I was nervous going in but everyone at Sigma is so kind and put me at ease. I needed four small fillings due to gum recession. Dr. Dashti is gentle and explains what she is going to do before she does it, and there's a TV on the ceiling to entertain you while you're having your procedure! Tyrone is personable and efficient, and the kind gentleman at the front desk is awesome. He obtained a prior authorization from my insurance so I knew what my out of pocket would be beforehand and everything was ready to go when I got there. My teeth look great! Thanks Sigma team! See you in six months. 😁Posted on Google![]()

Dr. Sepi Dashti provides an outstanding level of dental care. She is highly knowledgeable, professional, thorough, and attentive to her patients’ needs. She takes the time to explain each step of the treatment process clearly and ensures that patients feel comfortable and well informed throughout their visit. Her attention to detail, clinical expertise, and thoughtful approach to patient care are truly impressive. The entire office reflects the same high standard of professionalism and creates a welcoming and comfortable environment. I highly recommend Dr. Dashti to anyone seeking a skilled, trustworthy, and dedicated dentist who consistently provides excellent care.Posted on Google![]()

The dentist is very gentle and nice and I have been recommending her around the area. The office manager on the other hand was yelling / arguing with me when I tried to make an appointment for a specific issue. He made us not want to return or recommend. I believe he had mistaken me for another patient and would not even try to understand his mistake when I tried to correct him. Having dental work is already stressful and when the office manager doesn't have clear communication and is using contradictory phrases it makes the experience so much worse and degrades trust.Posted on Google![]()

I had my wisdom teeth removed at Sigma Dental recently, and the entire experience was far better than I expected given how nervous I was about the procedure. I was naturally a bit anxious heading in, but the team made me feel completely comfortable from start to finish. The dentist (Dr Septic Dashti) explained every step of the process beforehand, answered all my questions, and made sure I didn't feel a thing during the procedure. Post-op instructions were clear and easy to follow, making recovery smooth and manageable. Highly recommend Sigma Dental for anyone nervous about dental procedures!Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
