I am not from Houston, but I have been living here for seven months taking care of my daughter who is very sick. Since I was not able to go home for my regular dental cleaning (I go every six months religiously), I looked for a place to have my teeth cleaned that would accept my insurance. I found Castle Dental at 13486 Northwest Freeway, Houston, TX, which is close to my daughter’s neighborhood, on the provider list for my dental insurance. I was able to make an appointment very quickly, which I found rather strange. I should have followed my first instinct and stayed away. I thought that I was going to have x-rays, an exam, and a cleaning on the same day like I normally do. I am usually in and out of my dentist’s office within an hour each time. My experience with Castle Dental was a nightmare. I spent over two hours having x-rays, photos, and an exam. Then, instead of cleaning my teeth, they sent me back to the waiting room where I was directed into an office to discuss my x-rays with the male receptionist. He told me that I had periodontal disease, which I have never had before. I floss every day and brush at least two times/day with an electric toothbrush. The receptionist told me that I would need to have a periodontal cleaning, rather than a regular cleaning, which would not be covered by my dental insurance. They would need to schedule this cleaning on another day. I was suspicious and called my regular dentist of over 20 years to discuss this diagnosis with him; he checked my records and said that I have never had periodontal disease. My dentist advised me to get a second opinion from another dentist. After I ran a Google search on Castle Dental, I found out that Castle Dental ""diagnoses"" everyone that walks through the door with periodontal disease whether they have it or not. Of course, I was very sorry that I didn’t run a Google Search on Castle Dental before I wasted my time going there. I cancelled my cleaning appointment and paid $25 to have my x-rays loaded onto a thumb drive for my records. The next week I got another opinion about my dental health from a small private Houston dental office. They completed a regular cleaning and exam on me and did not agree that I had periodontal disease. I will never return to Castle Dental and would not recommend them to a dog!! Beware that this company also goes by Monarch Dental and Bright Now Dental, in addition to Castle Dental. DO NOT GO HERE!
