What Patients Are Saying About Rockville Dentist Dr. Leon-Guerrero

Big thanks to this group for fitting me in on a Friday afternoon to help with my toothache. I was feeling 100% better the next day. Dr. Guerrero did a great job and was really nice.
★★★★★
No one loves a root canal, but my experience with Dr. Leon-Guerrero was about as good as it can get. He used the numbing gel and that made the injection a little easier (my least favorite part). I fell asleep once we got started and when I woke up, the procedure was done. Haha cant get much better...
★★★★★
Dr. Leon Guerrero is an excellent endodontist. I went in for a difficult root canal and he handled it with ease. No problems nice he fixed it. Will definitely be a repeat customer if I ever need another root canal.
