    I hadn't been to Dr Marcus for about 3 years since my dental insurance had changed so I had to go elsewhere.

There were repeated recommendations for things that weren't necessary. Most concerning, there was a serious issue with my daughter's tooth/cavity that required us to see a specialist in Napa, who confirmed that the treatment should not have been done that way.

    Do not trust this practice with your care. I required a root…read morecanal on a tooth, and it was not my first. During my X-rays, once I found out I'd need the root canal, I explained to the dentist that I know from experience I need prescription pain medicine after root canals, as I have other health conditions that increase inflammation and pain. When I've gone without in the past, I've been in the most pain I've ever experienced for days on end. It was torture. I made it clear that I would not have a root canal without it due to how traumatizing it was and how much work I had to miss. She agreed and scheduled the procedure. After the root canal was complete, I reminded her of our conversation. She cited a study that said for most patients, Advil and Tylenol was fine, so she would not write a prescription. My face was too numb to even have a conversation about it. I feel deceived and lied to. I don't feel like my specific needs as a patient were cared about at all, and this is just a money grab. I'm so scared for how this recovery will go knowing what I've experienced. I couldn't have explained this any clearer to the entire staff. I want to trust dentists with my care so badly, and this damaged it. I will never be going back to this practice after this and I recommend others avoid it as well.

    I don't like leaving negative reviews, but this was by far the worst dental experience I've ever…read morehad, and I'm 65. My dentist of 35 years in SF retired so I found a new one locally. The dental assistant, who was very nice, asked about my last cleaning/exam. I told her it was one year ago. The very first thing she did was polish my teeth, then flossed, then took some X-rays. Dentist came in. Asked if I had any pain. Took a very (very) quick look (no tools used) and said everything looks fine, then used the ultrasonic scaler briefly and said there was a bit of tartar here and there. Said everything was fine and left. Never mentioned the X-rays. He was there maybe 5 minutes tops. This was a first appointment, mind you. No history taken. No real examination. No, "hi my name is Dr ___." No acknowledgment that he's never seen or met me. In contrast, my prior routine always went like this. Dental hygienist 1st. * Periodontal Probe: A tiny measuring tool or "ruler" used to check gum health and measure the depth of the pockets around each tooth. * Explorer: A hooked metal tool used to check tooth surfaces for decay, cavities, and tartar buildup (calculus). * Ultrasonic Scaler: Rapid ultrasonic vibrations w/high-pressured water spray to gently/efficiently blast away stubborn plaque and tartar from above and below thegum line. * Hand Scaler / Curette: Manual scraping tools with varying curves and sharp, pointy ends designed to scrape away plaque and tartar in areas the ultrasonic tool can't easilyreach. * Polisher: A rotary tool with a soft rubber cup that spins a mild abrasive paste over the teeth to buff away surface stains and make the enamel smooth, leaving teeth bright and shiny. * Floss Then the dentist comes in * Medical and Dental History Review: asks about changes to current medications, overall health conditions, and any new symptoms like sensitivity or pain. * Radiographic Examination (X-rays): Digital images are taken (or prior images reviewed) to spot hidden issues like cavities between teeth, bone loss, impacted teeth, or root problems. * Physical Tooth Examination: Each checked for decay, cracks, wear, and the structural integrity of existing fillings or crowns. * Oral Cancer Screening: Inspects face, neck, lips, tongue, throat, and tissues for any suspicious lumps, red or white patches, or abnormalities. * Bite and TMJ Check: Evaluates how teeth come together (occlusion) to detect teeth grinding, jaw popping, or TMJ (temporomandibular joint) disorders.
