Maintaining NNN Veneers is very simple. You need to treat them as you would your original teeth, with daily brushing and flossing.
You should also return to your certified NNN Veneers dentist for regular professional maintenance. This is because NNN Veneers should be polished with a specially formulated paste.
The certified NNN Veneers dentist will also need to inspect your dentistry for any sign of potential failure.
