Services
Serving the Mission Viejo area, our dental office is committed to providing our patients with compassionate and professional dental care of the highest standards in a comfortable and relaxed environment. After working in a quality control lab Dr. Botros realized he wanted to work directly with people, caring for them and interacting with them on a personal level.
Our comprehensive range of treatments includes: General Dentistry, Cosmetic Dentistry, Teeth Whitening, Root Canals, Dental Implants, and more! Root canal therapy is often an effective way to relieve and even save a damaged tooth and avoid more costly and exten. At OMD, it is always our goal to treat patients in the most cost effective and least invasive way possible.
Stained teeth can make you self-conscious and reluctant to smile. Holding your hand in front of your mouth instead of showing off that grin can make you seem unfriendly or shy. If that's the case, it is probably time you did something to make you want to show off those pearly whites. One of the most dramatic (and easy) changes to make to your smile is to have your teeth whitened professionally.

Love This Dental Office! Both dentist are very caring and conservative in their treatment plans. Never pushy and always make sure you understand your treatment options. Every procedure I have had completed at this office not only painless but also aesthetically pleasing. My hygienist Diane is very through and sensitive to you needs. I worked in the dental field for 22 years and this office is amazing! Give it a try, you won't be sorry.

I have been going to Oso Marguerite dental for over 5 years now and I will never go anywhere else unless I move out of state, lol. Dr. Kamila, Dr. Botros and their entire team are incredible! So professional and yet they feel like family everytime I see them. I just came back from a cleaning with Ashley and I love her. Super gentle but thorough. I should have started this by saying I have had a previous experience years ago that was less than spectacular and ended up being so scared of the dentist that I didn't go for a few years. Gross, I know but I was terrified. Dr. Kamila was so thorough, gentle and understanding over the next few months while she fixed my teeth! I absolutely love her:. I send everyone I know here! If you're on the fence looking for a lifetime dental care team, look no further, these are your people!

We were referred to Oso Marguerite Dental by our neighbor when we moved into the area and have been exceedingly happy with our experiences. The entire office has proven simultaneously professional and friendly, not to mention accommodating. Dr. Kamila has caught me up to where I should have been and has routine care scheduled out going forward. We have a new dental home.

I could not be happier with Oso Marguerite Dental. In addition to receiving excellent care on my normal dental needs, I recently completed Invisalign treatment. While I was skeptical at first, the ease of treatment and final product are amazing. Dr. Kamila was right- I could not be happier with my new smile!

Dr. Kamila is amazing. I was afraid of dentists and dealing with childhood trauma, Dr. Kamila understood me completely, she made me feel very comfortable and with each visit made me feel at ease. I finished my treatment today, this is the only place I will go to from now on. I highly recommend Oso Margueritte Dentistry.

This is the most caring and talented dental office that I have ever been to. They treat you like family and are so worried about how you got thru your appointment. They explain everything and will answer all your questions in detail. I would highly recommend Dr Kamilla and Dr Boutros for your dental needs!

So happy to have found Oso Marguerite Dental! Everyone at the office is extremely professional and caring! Hygienists, doctors are so thorough and gentle - really shows they care! They by far provide the best bedside manners! The office is currently undergoing a renovation - looking AMAZING! They are extremely conscious of keeping the office clean and well organized. Dr. Kamila Szczepaniec and Dr. Markos Botros take the time to explain the process, procedures and oral care so thoughtfully and thoroughly! Highly recommend! They are also great with sending text reminders for appointments.
