About Mark J. Williamson DDS

Mark J. Williamson DDS operates on Cherry Ridge Drive in San Antonio, Texas. At the core of a general dental practice is preventive and restorative care: checkups, professional cleanings, fillings, and screening for decay and gum disease before either becomes a bigger problem. It is the kind of appointment most people need on a routine schedule rather than only when something hurts.

Day-to-day oral health still comes down to the basics between visits — brushing twice daily with fluoride toothpaste, cleaning between the teeth, and limiting how often sugary food and drink appear through the day matters more than the total amount eaten at once. Regular professional care is what catches whatever those habits do not.

Digital X-rays are a routine part of dental care because they show what a visual exam alone cannot — decay forming between teeth, bone loss below the gumline, and how developing adult teeth are positioned in children. They use a low radiation dose and are taken on a schedule matched to individual risk rather than at every single visit.

Left untreated, small dental problems tend not to stay small. A minor cavity that would have been a straightforward filling can progress to needing root canal treatment and a crown, and early gum inflammation that would have reversed with a good cleaning can progress toward bone loss around the teeth. Catching things early is generally the difference in both effort and cost.

Continuity matters in dental care — seeing the same practice over time means your history, X-rays, and any patterns in your oral health are already on file, rather than starting from scratch at each visit. That familiarity is part of what a regular dental home offers beyond any single appointment.

Dental anxiety is common, and most practices are used to working with nervous patients — through clear explanations of what is about to happen, a slower pace where needed, and sedation options for patients who want them. Avoiding the dentist out of anxiety tends to make eventual treatment more involved, not less. Contact details for Mark J. Williamson DDS are on this page, along with the full list of services offered — reach out to ask about scheduling.

Dr. Mark J. Williamson and his Staff have been wonderful because they show their patients they really care about their health. Good Dental care affects your whole being starting in your mouth and spreading throughout your whole body. My Sweet Hygenist, Addie, has been the best: taking care of my teeth and always sensitive, gentle and very caring.

Outstanding!! If you need a cleaning, exam, something more, make an appointment today! What a great dental experience! I made an appointment at the urging of my wife since she was already a patient. I can’t believe how much time the dental hygienist Christy spent with me! Between x-rays, cleaning and Q&A time, we spent probably 90 minutes together. Then Dr. Williamson came in and spent another 30 minutes with me. Between the two of them, they answered all my questions and concerns. They even brought up topics of conversation they had with my wife, even talking about where my youngest daughter is in life and her accomplishments! I was amazed!

My recent experience with Dr Williamson was outstanding and very personable (crown installed). He and his staff make you feel as one of the family and welcomed. I have been a patient here for about 7-8 years and I have always received personal and caring treatment. I would highly recommend Dr. Williamson for your dental needs. Roger
