T.D.
Mid Valley Dental in Northridge is great. The staff is super nice and they are wonderful with kids. Their address is 8815 Reseda Blvd and their number is ###-###-####.
I've noticed several people recommended Dr. Zinnia Regala. We used to go to her but left because I didn't like how she kept telling my kids that they had to brush because they had "sugar bugs" in their mouths. What a great way to freak little kids out! I wanted a dentist who would be truthful and treat my kids like the intelligent human beings that they are.
Good luck!
