First, it’s important to maintain good oral hygiene practices. Brush your teeth with fluoride toothpaste at least twice a day. Be sure to use gentle motions. Floss daily. Be careful not to pull on the floss too hard, as this could cause the crown to become loose.  You should also visit your dentist at least twice a year for routine check-ups and cleanings. In addition, avoid chewing on hard foods or objects and using your teeth as tools, as this can damage the crown. Protect your teeth and crown by wearing a mouthguard if you play sports. Nightguards are recommended for people who grind their teeth at night.
