If properly cared for, veneers can last five to ten years. Top tips to help care for your veneers are: Avoid chewing on hard foods on the veneers for 24 hours from the time they were cemented in. Rinse your mouth 3x per day with warm salt water. Keep area clean to maintain tissue compatibility. Clean teeth at least twice a day and use a fluoride mouth rinse. Any concerns discuss with your dentist.
