Absolutely, if there's a good pediatric dentist in the area. There are certain standards I hold any dentist to: I can go in the exam room with my kids, no hassle. I can ask questions about proposed treatments and get intelligent answers. No mercury in my kids' fillings. Appropriate pain relief is provided, and no restraints are used.
Assuming those standards are met (and they really should be anyway), I would go with a pediatric dentist over one who generally only sees adults. In fact, we've been turned away by a regular dentist for my daughter because the dentist felt so strongly that my daughter would have a better experience -- and get better quality treatment -- with a dentist who specialized in working with kids.
Ours has a very colorful, welcoming, and engaging office, from the waiting room to the treatment room. The treatment rooms have butterflies and other shiny things on the ceiling for kids to focus on while they're in the chair. The chairs are kid-sized, but big enough for me to sit in if my children feel more comfortable on my lap. The sunglasses and other equipment is all child-sized, as well. There's a box of toys for siblings under every chair in the treatment room because they just assume that a parent won't always be able to find a sitter for siblings. They don't even ask that we do. Siblings are welcome. And the office is well stocked with prizes and positive reinforcement for after appointments, regardless of how the appointment goes.
In contrast, every adult dentist office I've been to has been pleasant, neutral, aseptic, tastefully decorated . . . nice, but really not kid-oriented at all. It's just not their focus, and a lot of things that an experienced kid dentist would do as a matter of course, an adult-focused dentist might not even think of.
