Your neighborhood dentist
Just a team that genuinely cares about the Bethesda Community
For over 100+ years, Dr. Mazziotta, Dr. Zebe, Dr. Chin and Dr. Samad have been treating families in Bethesda, Laurel, Bowie, College Park, and the surrounding communities. We know your name, we remember your history, and we're here when you need us.
How a neighborhood dental office in Bethesda became home for a combined 100+ years.

Four things that guide how we practice dentistry.
We explain everything before we do anything
You will never leave our office confused about what happened or what comes next. The Bethesda Dental Group team takes the time to show you your X-rays, explain your options, and answer every question — without making you feel rushed.
This community deserves accessible dental care
We accept all PPO insurance, offer Cherry financing, and have a new patient special for exactly this reason. Good dental care should not be something only some people can afford. That's not the kind of practice we want to run.
Being available is not optional
Dental emergencies don't happen at 2pm on a Tuesday. We answer calls at night, on weekends, and on holidays — because that's when people actually need us. It's that simple.
We treat patients like neighbors, not numbers
Our team knows your name. The Bethesda Dental Group team remembers your last visit. We have patients who've been coming here for over a decade — and their kids come here now too. That's the practice we've built, on purpose.
What over a century of experience looks like.
Every case below is a real patient, a real treatment, and a real outcome from our Bethesda office.

The reviews that mean the most to us.
We don't ask you to trust us. We let our patients do the talking.
I hadn’t been to the dentist in longer than I wanted to admit, so I was expecting a lecture. Instead, the whole visit felt easy. My cleaning was gentle, everything was explained clearly, and I left knowing exactly what to keep an eye on and when to come back.

I had a small chip on my front tooth that bothered me in every photo. I expected a much bigger treatment, but bonding was enough. The shade matches beautifully and the tooth still looks completely natural.

I drink coffee every day and felt like my teeth had gradually become much darker than they used to be. I wanted them brighter, but I definitely didn’t want that artificial super-white look. They helped me choose a shade that still looked like me, and the difference was exactly what I wanted. My smile looks fresher without looking “done.”

I avoided the dentist for years because of a terrible experience when I was younger. By the time I finally booked, I was embarrassed about both my teeth and how anxious I was. Nobody made me feel judged. They talked through the sedation options with me beforehand, explained exactly what to expect and made the appointment feel completely manageable. It was the first time I left a dental office thinking, “I can actually do this again.”

I used to think preventive dentistry just meant getting my teeth cleaned and coming back six months later. They actually took the time to explain why I kept getting cavities in the same areas and helped me change a few things at home. We also added extra protection to a couple of teeth that needed it. My visits feel much more proactive now instead of waiting for the next problem.

I had been dealing with jaw soreness and painful clicking for months and wasn’t even sure whether I should see a dentist about it. The appointment was very thorough. They asked when the pain happened, checked how my jaw was moving and explained the difference between the joint and the surrounding muscles. I appreciated that the plan felt conservative and specific to what I was actually experiencing.

I had already been diagnosed with sleep apnea but struggled with my CPAP enough that I wasn’t using it consistently. I talked with my sleep doctor about alternatives and then came to Bethesda Dental Group for an oral appliance. The fitting process was easy, the adjustments were explained clearly, and traveling is much simpler now. My wife is also very happy that the snoring has improved.

I had a badly broken molar and kept putting the appointment off because I was nervous about having it removed. They showed me why the tooth couldn’t really be saved, talked me through everything before starting, and the actual extraction was much more manageable than I had built it up to be. I also appreciated that we talked about what to do with the space afterward instead of just stopping there.

I went in with a toothache that had kept me up the night before and was honestly dreading hearing “root canal.” The team explained exactly what they were seeing and what would happen next. Once I was numb, the appointment was much easier than I expected, and the relief afterward made me wish I had come in sooner.

I chipped an old filling and was convinced it was going to turn into a much bigger procedure. Dr. Shawn showed me exactly what was happening, explained my options clearly, and repaired the tooth without making the visit stressful. My bite feels completely normal again, and the new filling blends in so well I can barely see it.

Cracked my tooth on a Friday night eating dinner.
Called at 9pm expecting a voicemail. Someone picked up immediately, gave me an appointment for Saturday morning, and Dr. Shawn fixed it in one visit. Unbelievable service.

“I hadn’t been to the dentist in four years because of anxiety. Dr. Shawn was so patient with me. He explained everything step by step and I didn’t feel a thing. I’ve already booked my next cleaning.”
