As you know, your own teeth require conscientious at home oral care and regular dental visits. Dental implants are like your own teeth and will require the same care. In order to keep your implant clean and plaque-free, brushing and flossing still apply!
Cleaning around the teeth attached to the implants should not be any more difficult than cleaning natural teeth. However, there may be difficult to reach areas and you will be shown how to clean these properly. You may need to visit the hygienist more often, but your dentist will be able to talk to you about this.
