How to maintain zirconium crowns?

To care for zirconium dental crowns, brush your teeth twice a day with a soft-bristled toothbrush and non-abrasive toothpaste, and floss regularly. Avoid chewing hard foods, especially ice or nuts. See a dentist at least twice a year. Those who grind their teeth can protect their crowns by wearing a night guard. With proper care, zirconium crowns can last between 10 and 15 years, and in some cases, even longer.
