    Dr Mardock took my smile and confidence away!…read more Dr Mardock May be great for extracting teeth but DO NOT go to him if you want major work done. Especially if you can't afford to go to another dentist to have them redone. I went to Dr Mardock because I have teeth missing and a few cavity's that were not bad. Over a period of 2 yrs my cavity's were not his concern so I didn't think they were bad. He proceeded to make a bottom partial for my missing teeth and told me he was going to put crowns on my six front top teeth. He didn't even address the broken and decaying teeth. You would think a dentist would fix the base problems before working on replacements. I was confused when he put my crowns in when I realized they weren't individual crowns. There were two pieces with three teeth on each one. The teeth were HUGE. I had very small teeth and I actually cried when I got home and looked in the mirror. The teeth were so big when I smiled my front teeth overlapped my bottom lip and pulled my lip in when I stopped smiling. He gave me buck teeth! He ground them down to make them shorter but now my left side of my teeth touch but the right side has a gap between the upper and lower teeth. After a few months a piece of the crown came out at the gum line, my crowns have shifted causing a gap between my two front teeth and the crowns are loose. I have a small gap between my gum and the partial which left a sharp edge I complained about . He said he could fix it but never did. He didn't act as though he cared at all. One eye tooth was shaped like a ball so my teeth felt so awkward when I closed my teeth together. I now have an overbite. My crowns also slanted outward making my teeth look really strange. Dr Mardock then had the nerve to tell me I may need braces! Braces for crowns you just put in my mouth?!? My real teeth were smaller and perfectly straight when I walked in the first time. I've never needed braces in my life! Now I have huge teeth that look so bad I can't smile. My friends and family were shocked when I showed them. He then made a partial for my missing teeth on the bottom. The partial was very painful and cut my gums. I went to have adjustments done four times and gave up. He ground off part of my real teeth to make the right side fit but when I put them in my mouth and bit down my right side popped completely off. All he could say was it wasn't like that when you walked in. Exactly my point! He talked to me like I was a child. I cut my losses and went to another dentist who couldn't understand why he would put a partial in my mouth in the first place at that point because both the teeth my partial hooked on to needed root canals and he didn't remove a tooth that had broken at the gums. Now the teeth that supported the partial are breaking. He just put the partial over the broken off tooth. In the mean time the cavities he ignored in the beginning are so decayed now I need root canals on four teeth and possibly will lose them. Not to mention the pain I am in. I am now self conscious about my teeth and try not to smile so they show. Several months after all this happened I was visiting a friend in the hospital and I started talking to another visitor about my experience. She explained to me that her dentist did such a bad job replacing her teeth with crowns that she got into an argument with him about it. She said she had to go to another dentist who had to remove the crowns and replace them. That dentist wondered what dr Mardock used to glue in her crowns because they had to grind them off so they could start over. At the expense of thousands of dollars. She then asked "It wasn't Dr Mardock in Cedar Hill was it,? I was shocked and said omg yes it was. She said he was the one who messed up her teeth also! This dentist should not be allowed to continue to destroy people's teeth and self confidence! It doesn't end there! I talked to a man who said he had to go to another dentist (Dr Seidler) after he had a few fillings done because the filling fell out within a year! I'm sure there are many more people out there who were just as devastated by his work. Stay far away from this dentist if you want to keep your smile. Dr Mardock took my smile! I'm trying to figure out how to post pics on here so I can put before and after pics that show how huge my teeth are and how they slant outward compared to what my real teeth look like!

    Just left another dentist appointment I am a smoker and I swear I received the best cleaning today…read moreI had quite a few tobacco stains and they removed everything I love this office and all of their staff.

    Everyone knows going to the dentist is terrifying--no matter how old you are, especially at my big…read moreage lol. I just want to take a moment to thank Breezy for being so patient and kind with me. I originally went in thinking I would have to get my tooth removed due to financial concerns and honestly, fear of needing a root canal. Breezy took her time with me, reassured me, and encouraged me to save my tooth by getting the root canal and crown instead. Because of her, I spoke with the office manager and was able to get on a payment plan that worked for my budget while still getting started the same day. When I went to the back, Breezy literally held my hand while I was being numbed and never left my side. That meant more to me than she probably knows. Her kindness and patience truly made a difference. I also want to thank Dr. Michael Wistrom, who performed my procedure--you were incredibly gentle, patient, and efficient. The procedure was quick and, most importantly, painless. As the numbness is wearing off, I feel great--no discomfort at all. As a busy mom, I was so nervous about the aftermath, but I honestly feel amazing. This experience gave me the confidence to move forward with completing the rest of my dental work. Breezy, you are truly special. You can tell when someone genuinely loves what they do, and it shows in your care. I pray you continue to be successful--you really touched me today. Exceptional customer service like this is rare, especially in this field. I can't wait to come back for my permanent crown. Thank you all again!

    My experience with Modern Dentistry was extremely disappointing and concerning. The dentist…read morerepeatedly pushed a $425 quarterly deep-cleaning procedure (this cost was for each side of my mouth--on top of what my insurance already covered--and claimed they could not perform a standard cleaning unless I agreed. I was told I had gum disease, which later proved to be false. I sought a second opinion at Precision Dental & Orthodontics, where I learned I did not have gum disease. Instead, I had one tooth needing targeted care. Additionally, the crown Modern Dentistry placed on my back tooth failed twice, and Precision Dental was able to correct their work for half the cost, with no out-of-pocket expense from me. The office manager at Modern Dentistry attempted to pressure me into unnecessary laser and chemical deep-cleaning services, insisting they were mandatory. After reporting the issue to Humana, I was informed that the office had even placed Humana on a block list when contacted for verification. Based on my experience, Modern Dentistry operates in a predatory manner, especially toward seniors. I strongly recommend that anyone considering this office research other providers and compare pricing and treatment plans before moving forward. These people lie and appear to work in a criminal manner!!!

    Was referred to Dr. Sheppard from my dentist. Needed a tooth extracted from a previous root canal…read more I was very nervous and had lots of questions during my consultation. After getting the reassurance from the Staff and doctor I felt at ease. We proceeded with doing the extraction the same day. My goodness, from the time it took for the anesthesia to kick in, which was quick, Dr. Sheppard came back in the room and did the extraction. It happened so fast, I was shocked! I hands down recommend Dr. Sheppard for any tooth extractions.

    Got all 4 of my wisdom teeth pulled and was told before I was took back to the operation room that…read moreI would be getting hydrocodone after my extractions for pain then once I'm in the operation room they change it to regular Tylenol my husband was trying to understand up front on why they changed there mind while I was under and was told this doctor does not prescribe them for pain I was already super nervous iv never had anything like this done before besides a c section fast forward after we pick up the prescription I take one as told for pain ( my upper jaw hurting to badly ) this is about 2 hours after we left I wait a little over a hour to be sure that what I was gave would come into effect sadly it did not I have been crying in pain since the minute I took it and called them to tell them I am in so much pain and have been crying since and mind you this hurt way more then a C-SECTION I told them I have never been in this much pain before and that what they gave me was not working and asked for the hydrocodone they brought up in the first place ( mind you I have had friends and family tell me that is what they got after and they where just fine) I walked in there nervous but glad my pain would be handled in after care and it's was OBVIOUS THAT IT WAS NOT back to the phone call they proceeded to tell me that I just need to take I ibuprofen for the pain I took 5 ibuprofens at once and I'm still in pain crying this office does not care about your pain management post op what so ever I would not recommend to ANYONE NEVER GET WORK DONE HERE
