Modern restorations are made of all-ceramic materials, so they shouldn’t discolor. Whitening products won’t have any effect on their color because crowns aren’t porous. Your dentist will advise against whitening treatments because their ingredients can weaken the bonding material holding your crown in place over time. It can also lead to inconsistencies because your enamel will get lighter, but your crown will be unchanged, causing it to stand out. Your cosmetic dentist can create a personalized plan to reverse discoloration while ensuring seamless results.
