E-max laminate veneers are bonded to the front surface with minimal preparation. Lifespan depends on bite, grinding and regular checks. Biting hard objects is the most common reason a veneer chips.
Care is close to natural teeth: brushing, floss and professional cleaning at the intervals your dentist sets. If you grind, a night guard is part of the plan.
Coffee or tea rarely stain the ceramic itself; the real risk is neglecting the gum line at the bond.
