About Harmon John DDS

Harmon John DDS focuses on saving teeth. Root canals top the list, especially molars where precision matters; retreatments come next when earlier work needs refreshing. Those stubborn cracks or chips? They handle vital pulp therapy before the damage widens. Trauma cases roll in too—knocked-out or pushed-in teeth get triaged fast. And if a tooth feels perpetually sensitive, they’ll trace the source in a single visit.

Just south from The Northshore Harbor Center along LA-1066, the practice sits at 800 C M Fagan Dr STE E, Hammond, LA 70403—Suite E marks the door, easy to spot if you know the plaza. Between AMG & Pelican State Credit Union, the one-story office shares parking with a fitness studio and a hair salon. Plenty of pull-through room keeps traffic moving on weekdays.

Need to lock in an appointment? Tuck the number away now: *(985) 345-2828*. Driving over? Bring the directions on your phone; the route pops right into your GPS without detours south of city hall.
