As a dentist myself, finding an endodontist I could trust completely was really important for me. I found that level of trust here. This clinic offers thelatest technologies, such as GentleWave and Fotona, which are really advanced and they can enhance the treatment process overall. Dr. Dianat has outstanding skills and thorough approach. He doesn’t just perform the procedures but critically evaluates all possible treatment options and explains them in a nice and clear way. His clear communication is very helpful! The team at this clinic is remarkable. Behgum, in particular, demonstrated great expertise in taking radiographs. Another thing about this place is same-day emergency appointments!

My experience at Irvine Endodontics was wonderful. Everyone working at this dental office is kind and caring and made me feel very comfortable and calm prior to my root canal appointment. Dr. Dianat was very understanding and comforting when I had shared my past trauma related to a root canal I had with a different doctor. I was very anxious and scared to get a root canal again because of the horrific pain I felt during my previous procedure, but Dr. Dianat and his staff assured me that I would not feel any pain as they created a medication plan specifically to help me relax and to reduce anxiety in preparation to my root canal. Thanks to this plan, I was calm and did not feel any pain. Thank you Irvine Endodontics for making my root canal experience an anxiety and pain free procedure. I highly recommend this location if you are in need of a root canal.

Dr Dianat is vey professional and has great skills, he successfully treated my teeth which has multiple calcified roots that are hard to access. The assistant, Hafsa has great spirit and listens to all my concerns, her presence helps keeping me calm. Overall I highly recommend this dentist office.

THE ROOT CANAL DREAM TEAM!! I was so nervous about getting my first root canal and had no idea what to expect but I am so thankful I listened to the other reviews and came here. I had a very complex case and Dr. Dianat was able to determine which tooth was causing me a lot of discomfort. I literally had ZERO PAIN!! Dr. Dianat was extremely gentle throughout the entire procedure and very informative. He took his time to explain things to me and was very thorough. His assistant, Behgum was so sweet, supportive and kind! She made me feel very comfortable and communicated with me the entire time. If I ever need another root canal, this is truly the only place I will go. Thanks again Dr. Dianat and Beghum, you guys are amazing!

My experience at Irvine Endodontics was the best dental experience I’ve had so far! Everything about this center is just perfect! Dr. Omid Dianat is a true genius in the field of endodontics. It takes multiple visits to different dentists to truly appreciate his skill and capability to his practice. My case was particularly challenging, yet he handled it with expertise and care. I experienced a totally pain-free root canal treatment. What also truly sets him apart is his ability to find and treat hidden root canals that other doctors had missed, which had previously led to secondary infection in my case. Staff and assistants at the clinic were kind and helpful. They explained everything to me patiently, ensuring I was comfortable and informed throughout the process. I will definitely drive again from LA if I need to do any root canal treatment in the future.

So happy I came across Irvine Endodontics when I learned I had a severely infected tooth from a previous root canal I had done elsewhere. They made sure I was comfortable throughout the entire process of cleaning out my infection, and I had zero pain during it. Highly recommend them if you’re in need of a root canal!

I was recommended to Irvine Endodontics by my dentist office for a consultation of a possible root canal. The entire staff were welcoming and very helpful. And after the consultation which was at 3pm in the afternoon, they were able to complete the root canal procedure in less than 45 minutes the same afternoon. I would recommend Irvine Endodontics to anyone who is in need of Endodontic procedures.

If you want top notch dental care, this is the place you want to visit. Dr. Fay Mansouri and the staff are extremely patient, empathetic, and accommodating. They explained everything to me in great detail and made me feel comfortable about the procedure. I would highly recommend coming here; don’t even think twice.

Dr. Mansouri and the NightLase anti-snoring treatment are an amazing team! Dr. Mansouri is talented, kind, and sweet. NightLase is the best way to treat snoring ever. Over a series of 5 treatments (spread over about 4 months), the excess tissue in my tongue and airway that was a big cause of snoring was reduced substantially. Voila! SnoreScore (from SnoreLab app) drops dramatically and more importantly, my wife sleeps soundly through the night. NightLase treatments didn’t hurt and had no after effects. I strongly recommend that snorers visit Dr. Mansouri and ask about NightLase.

Dr. Kimia M.

I love this dental office. My husband was referred to Irvine Endodontics because he needed three root canals. Dr. Mansouri and her employees went above and beyond to make us feel comfortable. My husband has always been apprehensive of the dentist however, this dentist is completely different. The office looks like a luxury boutique. The atmosphere is friendly and welcoming. When it came to financials the coordinator did not rush us by being pushy. She explained in detail that my husband’s dental insurance will be maxed out halfway through the treatment needed. She then presented us with multiple options including zero% financing to cover the cost of treatment. Dr. Mansouri patiently explained the pros and cons of waiting until January to do the rest of the treatment. We decided to move forward with the treatment and we are very happy with our decision. By the way they have a CT scan and a microscope at this office which helps the Dr. do a thorough evaluation & treatment for her patients. I want to give a special thanks to Dr. Mansouri and her super star team at Irvine Endodontics.

I was a patient of Irvine Endodontics last Wednesday 11/10. Dr Omid Dianat was so kind and made sure i was comfortable from the very start, he has light hands and did a great job on my root canal. The assistant Behgum was very kind and made sure I was comfortable. To both I am very grateful, thank you!
Everyone in the office were very accommodating and were friendly. i highly recommend this office especially to patients who get nervous and have the jitters when seeing a dentist.

Sorry for the overdue review, but I definitely want everyone to know about this treatment. I’ve been having snoring problems for a while where my family has complained about how loud I snore. Luckily I found Dr. Mansouri!! She is amazing, super nice, very great to patients, personable, listens to your concerns, I could keep going. I did the night lase treatment which consists of 3 easy treatments and yearly touch ups after. After the first treatment, my snoring immediately went away, how I can tell, my partner actually slept through the night without throwing a pillow in my face :-) I was at first skeptical about the treatment because in my mind I’m thinking, how could laser treat snoring?!? But it really does!! I stand by this fully so if anyone out there is a LOUD snorer or a SNORER in general, I highly recommend night lase, especially with Dr. Mansouri. She explains every step of the way and tells you what she’s doing during the procedure. It has been almost half a year and I haven’t been thrown in the face with a pillow so it’s saying something :-)

Tooth Pain Treatment in Irvine – Find the Cause, End the Pain

Tooth pain has a way of taking over everything — your sleep, your meals, your concentration. If you're searching for tooth pain treatment in Irvine, the most important step isn't just relieving the pain; it's finding out exactly what's causing it. At Irvine Endodontics, board-certified specialist Dr. Omid Dianat combines advanced diagnostics — pulp vitality testing, percussion testing, and 3D CBCT imaging — with same-day treatment, so most patients walk out of our office with their pain resolved and their tooth saved. With an average 2-hour emergency response time, relief is closer than you think.

In pain right now? Call 949-540-9891 — we're an endodontist open today in Irvine, CA with same-day emergency appointments.

Common Causes of Tooth Pain We Treat

•  Infected or inflamed pulp: Deep decay or trauma lets bacteria reach the nerve inside your tooth, causing lingering sensitivity or a severe toothache. Treatment: a gentle, often single-visit infected tooth root canal.

•  Tooth abscess: A pocket of infection at the root tip causing throbbing pain, swelling, and sometimes a pimple-like bump on the gums. Our tooth abscess treatment in Irvine, CA relieves pressure and eliminates the infection at its source.

•  Cracked or fractured tooth: Sharp pain when biting that disappears when you release is a classic crack symptom. Early cracked tooth treatment in Irvine can save a tooth that would otherwise be lost.

•  Failed previous root canal: Pain returning in a treated tooth — or a broken tooth after a root canal — usually means reinfection or a new fracture. Retreatment gives the tooth a second chance.

•  Referred pain: Sometimes the tooth that hurts isn't the tooth with the problem. Sinus pressure, jaw muscle issues, and neighboring teeth can all mimic a toothache — which is why accurate testing matters before any treatment.

Complete Root Canal Services for Orange County Patients

•  Root Canal Treatment: Single-visit, microscope-guided therapy for infected and inflamed teeth

•  Emergency Root Canal: Same-day care for severe tooth pain, swelling, and dental trauma — average 2-hour response

•  Abscess Tooth Treatment: Fast relief and infection control when a tooth abscess strikes, before it spreads

•  Root Canal Retreatment: Expert correction of failed or reinfected root canals performed elsewhere

•  Cracked Tooth Treatment: Early intervention that saves cracked teeth before the fracture spreads

•  Apicoectomy: Root-end microsurgery for cases a conventional root canal can't fully resolve

Why an Abscessed Tooth Can't Wait
Of all the causes of tooth pain, an abscess is the one that should never be ignored. A tooth abscess is an active infection, and without treatment it spreads — into the jawbone, the soft tissues of the face and neck, and in rare cases into the bloodstream. Warning signs include throbbing pain, swelling of the gum or face, a bad taste in your mouth, fever, and a bump on the gums that may drain. If you notice these symptoms, don't wait for them to pass: abscess tooth treatment in Irvine, CA is available at our office the same day you call.

How We Diagnose the True Source of Your PainEffective treatment starts with an accurate diagnosis — and this is where specialist care makes all the difference. Your visit includes:

•  Cold and heat pulp testing: A brief, controlled stimulus tells us whether the nerve inside the tooth is healthy, inflamed, or no longer vital — each response points to a different diagnosis.

•  Percussion and bite testing: Gentle tapping identifies inflammation around the root and helps distinguish a cracked tooth from an infected one.

•  3D CBCT imaging: A cone beam CT scan reveals what standard X-rays miss — hidden infections, bone changes, extra canals, and fractures — so we treat the right tooth for the right reason, every time.This thorough approach protects you from the two most frustrating outcomes in dentistry: an unnecessary root canal, and a treated tooth that still hurts because the real cause was never found.

Same-Day Relief from Severe Tooth Pain
When you call our office with severe tooth pain in Irvine, we treat it as the emergency it is. We reserve appointment slots daily for urgent cases, and our average response time from call to chair is just 2 hours. Unlike searching for a walk-in endodontist in Irvine, CA and hoping for an opening, one phone call secures your same-day appointment — evenings before weekends included, so a Friday toothache doesn't have to ruin your weekend. Whatever the diagnosis, our goal is the same: end the pain at its source and save your natural tooth.

What to Do for a Toothache Before Your Appointment

•  Take over-the-counter pain relief as directed (ibuprofen or acetaminophen) — but never place aspirin directly on the gums, which burns the tissue.

•  Rinse gently with warm salt water to soothe irritated tissue.

•  Apply a cold compress to the outside of your cheek for swelling.

•  Avoid very hot, cold, or sweet foods, and don't chew on the painful side.

•  Don't delay: home remedies manage symptoms, but they can't remove an infection. Call 949-540-9891 for real toothache relief in Irvine.

Frequently Asked Questions About Tooth Pain Treatment

Q1. When is tooth pain an emergency?
Seek same-day care if you have severe or throbbing pain, swelling of the gums or face, fever, a bump on the gums, pain that wakes you at night, or a tooth injured by trauma. These signs point to infection or damage that worsens without treatment.

Q2. Will my tooth pain go away on its own?
Occasionally mild sensitivity settles, but pain from an infected nerve or abscess does not resolve on its own. If pain stops suddenly after weeks of hurting, the nerve may have died — the infection is still there and still spreading, just silently.

Q3. Does tooth pain always mean I need a root canal?
No. Tooth pain can come from cracks, gum issues, sinus pressure, or a neighboring tooth. That's why we test before we treat — cold and heat testing plus CBCT imaging confirm the diagnosis first, so you never receive a root canal you don't need.

Q4. How quickly can I be seen for severe tooth pain in Irvine?
Our average emergency response time is 2 hours from your call to your appointment, with same-day slots held daily at our Irvine office.

Q5. What does a tooth abscess feel like?
Typically constant throbbing pain, pain when biting, swelling near the tooth, sensitivity to temperature, a bad taste from drainage, and sometimes fever or facial swelling. An abscess is an active infection and needs prompt treatment.

Q6. Can a cracked tooth be saved?
Very often, yes — if treated early. Cracks that reach the pulp can be treated with root canal therapy and a protective crown. The longer a crack is left, the deeper it travels; once it extends below the bone, the tooth usually can't be saved. Early evaluation is everything.

End Your Tooth Pain TodayYou don't have to push through another sleepless night. With accurate diagnosis, gentle same-day treatment, and a specialist team that treats your pain as a priority, relief is one call away.
