About Dr. Dai Tonthat, DDS
Dental care doesn’t have to feel like a chore—especially when you’re near Harder Road, where Hayward’s mix of residential quiet and commercial convenience makes running errands a little easier. On that stretch, you’ll find a dentist’s office handling everything from routine cleanings to more involved procedures. Preventive care, fillings, crowns, and even basic orthodontic evaluations get covered here, so it’s one of those places where you can knock out a checkup or address a nagging issue without driving halfway across the East Bay. The area itself is straightforward: mostly low-key businesses, a few strip malls, and none of the downtown hustle. If you’re already in the neighborhood for groceries or a quick bite, adding a dental visit to the list isn’t a detour—it’s just another stop.
For anyone mapping out their next appointment, the office sits at 434 W Harder Rd, Hayward, CA 94544, a few blocks from the intersection with Mission Boulevard. Questions about insurance, scheduling, or specific treatments? A quick call to (510) 293-0900 clears up the basics without the back-and-forth of emails. And if you’re new to the area or just bad with directions, the map pins it right between a taqueria and a pharmacy—because nothing says “adulting” like a dental visit followed by tacos and a prescription pickup.
