Maintaining porcelain dental crowns is actually quite simple. Much like your original teeth, they require routine brushing with non-abrasive fluoride toothpaste and regular flossing. A follow-up appointment will be scheduled to evaluate the crowns shortly after they’re placed, so the dentist can review the work and see how your mouth is reacting to the crowns. Even if you think the crowns are successful, this follow-up appointment is an important part of your future oral health.
