(…)I have had extensive dental work since a very young child and I can honestly say that 360 Dental is the ONLY place I can go where I know the work will be done thoughtfully, thoroughly and with the best quality and craftsmanship as it pertains to cosmetics, pain management and true state of the art technology . The  prices are affordable and Dr. Mitra is very accommodating to work within your abilities to pay. I cannot say enough about this office. I have referred family and friends who have traveled from out of state and many miles away to take advantage of her unbelievable 6 month orthodontia services!! I have personally had surgical and cosmetic work done and Dr. Mitra is a true perfectionist who will not rest unless and until everything is done perfectly and all are satisfied!!

Thank you 360 Degrees, they truly do Do IT All there!!

Dr. Macmillan and her office staff are wonderful, my family has been going to her for years. The staff is well trained and always welcoming and efficient. Dr. Macmillan is the best dentist I have ever been to,  kind, caring, very professional and always on time. I have never had a problem getting an appointment at the last minute if needed. All of the procedures I have had done were needed  and the cost was the industry norm.  I would give her more stars if possible.

I’ve never had straight teeth. I’ve always wanted straight teeth (like on the ad’s) I’ve never had braces, I’ve only tried Invisalign and I didn’t get the results that I was looking for. I saw the offer for 6 months braces and thought to myself, I gave Invisalign a year and a half, why not try 6 months. I scheduled an appointment, that was easy. I had a consultation, that was easy. I came back a week later and had the braces put on, that was easy. This place is a well oiled machine! I never waited longer than 5 minutes to be seen, I was in and out of my appointments within or less than 20 minutes, the girls were always so nice and professional and I GOT RESULTS!!! I am so happy with the experience and my results I can’t believe it! All it took was 6 months, wish I would have done this years ago! CANT STOP SMILING!

Sahar F. from Yorba Linda, CA (Source: Yelp)


Dr. Macmillan has been my dentist for over 3 years. I’ve had cleaning done, cavities repaired, and I’ve done the “six month braces” through her.  Each visit has been lovely – she is very knowledgeable and very compassionate and her staff are all great too. I’ve always gone in with my very young daughter and they have toys and made accommodations for us so she is entertained. Dr. Macmillan is awesome and I most definitely recommend using her services.

Beautiful and spotless office, very friendly and professional staff and Dr Mitra is very kind.

Steve H. from Santa Ana, CA (Source: Yelp)


Dr. Macmillan and her staff are the best — friendly, courteous, and very professional(…).
I have now been a patient since 2010 and highly recommend 360 Dental to anyone.

Ivana B. from Carlsbad, CA (Source: Yelp)


I came here for a second opinion on a crown that needed to be replaced, and I’m so glad I did. Dr. Macmillan is great, the staff and office are really nice, and the prices are reasonable. I couldn’t ask for more. I’d recommend 360 Dental to anyone. Also, If you need braces, this is the place to go. Dr. Macmillian specializes in the new “6 month braces” technique(…).

Joe R. from Placentia, CA (Source: Yelp)


Love 360 dental, Dr. Mitra is amazing, quick, and gentle! I drive an hour just to see her! Best dentist I’ve had in a very long time!

D. P. from Corona, CA (Source: Yelp)


This office is a few years old and  has state of the art equipment. The staff are friendly and Dr. Mitra Macmillan is Great. I am glad to find a professional who understands appointment times and doesn’t make you wait. I have come twice a year here since it opened to get my teeth clean,etc. I recommend her to anyone afraid of needles as I hardly feel the numbing agent going in to fix a cavity or crown and my face and lips do not feel big and heavy, or  being numb for longer than it  needs to be.
I have been to some rough dentist before. In my book Dr. Mitra Macmillan is one of the best!

I had the earliest appointment, so there was no wait. The receptionist, hygienist, and the dentist were all super nice and welcoming. The dentist took her time explaining everything to me(…).

Christina (Source: Groupon)


No waiting time, actually went in to see the dentist at my appointment time. Dentist was kind and very honest.

Francis L. from Palos Verdes, CA (Source: Yelp)


I’ve been going to Dr. MacMillan’s office for a couple of years now.  First of all, the office is extremely nice and clean.  The staff is very caring and paying attention to all your needs.  Dr. MacMillan herself is extremely knowledgeable and very gentle.  There is no reason, really, to be afraid of going to the dentist when you’re going to be treated by Dr. MacMillan. She’ll present you with a number of options to get your perfect smile back and she’ll make sure the one you pick will give you 100% satisfaction.  I’ve never had to go back to fix or readjust any crowns or anything
else she set up for me in the first place.

Great service, great people and ALL staff very professional…

Darlene K. from Tustin, CA (Source: Yelp)


It’s been 2 months since my braces have been off and I’m still very happy with my results. First time I had braces cost me around the same price and I had to wear for 2 years.. Second time, paid about the same and a little more to wear my braces for LESS THAN 6 months because I didn’t have a lot of things going on so we just did what was enough.

Everyone who works there is really sweet and nice. You always get in when it’s your appointment time and they’re very efficient. I came to this place after I saw a friends’ teeth that was STRAIGHT and before, it almost seemed impossible that his teeth could ever be straight but these new braces that 360 has, they are magic. DO NOT SPEND (a few thousand dollars) to wear braces for 2+ years, DO SPEND IT HERE for 6 months. I wish I had known this place before going to the other one.

Not only did my braces get off early, doctor even helped fix a chipped tooth and made it similar to my other teeth so they looked even (without me even asking her to do so). That was really nice of her to do that for me!! 🙂

Super friendly! Office was really clean and inviting and they were fast! Easiest teeth cleaning I’ve ever had! I would definitely recommend them!

J. B. from Irvine, CA (Source: Yelp)


Have been here twice.  Once for a cleaning and once for a few fillings.  Both times the staff was kind and helpful.  Both times Dr. MacMillian made me feel comfortable and welcome.  She clearly uses state of the art tools which makes everything faster, safer, and less disruptive to your day.  

After the cleaning I had zero soreness.  After the fillings, again, zero soreness.  I cannot believe how seamlessly the procedures were done and how quickly they were finished.

Dimas F. from Whittier, CA (Source: Yelp)


Amazing dentist,very informative,very gentle. I’m very happy here and I would highly recommend this dental office to anybody  looking for a great dentist dr. Macmillan was outstanding. This will be my future home for dental work.
I find the prices are really good and they offer good savings.
The receptionist and the dental assistant are very nice and the office is immaculate, of all dental offices I’ve been to this is an upscale professional level dental office

Nataliya A. from Corona, CA (Source: Yelp)


I’ve been a patient of Dr. Macmillan now for over 14 years. Followed her from office to office. My family would not see anyone else, even my in-laws come here (…). I’m not a stranger to a dental business and  worked in many dental offices and dealt with many dentists…. She is hands down best I have ever met. Thank  you Mitra!!!!

Leigh-Anne K. from Denver, CO (Source: Yelp)


(…)For a reasonable price I got my teeth cleaned very thoroughly, x rays, great customer service and NO sales pitch. The doctor even told me I have no deep pockets to justify  a deep clean and apologized for all of the dentists who’ve tried to take me for a ride. How sweet! She was really gentle and nice and I had a lovely, pain free, thorough cleaning.

I will definitely be coming back! Thank you so much! You guys have no idea what a struggle it has been to get my teeth taken care of!!!

I thought the receptionist and the back office was very nice and friendly and the dentist was very through and knowledgeable and they also gave me a splash guard for my eyes and for the light and they also had some Vaseline for my lips because they were dry and NO other dental place every offered that to me, I would highly recommend this place and they also had a dental plan as well that they offered, They also printed me up a paper of all the work that I received.

I bought (a deal) for my son who lives in California. He was very pleased with everything about this office. We appreciate their honesty(…). Thank you 360 Dental.

Kim A. from Irvine, CA (Source: Yelp)


(…)My teeth cleaning was done painlessly, even though I had a lot of tartar built up.  I can honestly say that I haven’t seen my teeth that clean EVER.  I had been seeing an “old school” dentist who used a pick and the little rubber buffer with the cherry flavored scrub.  This time, the technician and the dentist had my teeth not only painlessly cleaned, but polished to a level I’d never experienced.

The dentist, Dr. Macmillan, was professional and kind.  We discussed cosmetic treatments at my request and she gave me lots of information not only for an inexpensive solution but also the “elite” solution which was much more costly.  I liked having the options presented so I could make an informed decision.

Can’t say enough about my experience with 360 Dental.  It was excellent in every way and I’ll definitely be a patient there long term.

Tim S. from Trabuco Canyon, CA (Source: Yelp)


360 Dental takes the pain out of visiting the dentist. Dr. Macmillan is absolutely fabulous, friendly and informative. The office utilizes the latest technology to help make each visit efficient and pain free, such as a chair mounted flat screen providing an instant view of your x-rays and a water lase to replace shots and noisy drills. Dr. Macmillan gave me the right information to help me make informed decisions about my dental care.

Carlos S. from Tustin, CA (Source: Yelp)


I had a great 1st experience at this office. Everyone is so nice and they have all the new technology and which is great. Overall I would recommend this office to friends and family.
