Why Teeth Become Discolored
Tooth color changes for several reasons. Some stains sit on the outer surface, while other color changes come from within a tooth. Identifying the cause helps determine whether cleaning, whitening, restorative care, or another approach makes sense.
Surface stain is different from internal discoloration
Coffee, tea, tobacco, and other exposures may contribute to surface staining. Natural aging and changes within the tooth can also affect color. One tooth that suddenly darkens, especially after an injury, should be evaluated rather than treated with a whitening product at home.
Whitening has limits
Whitening products change the color of natural teeth but generally do not lighten crowns, veneers, or fillings. A cleaning may remove some external stain without changing the underlying tooth shade. Cavities, gum problems, and sensitivity should be addressed before bleaching is considered. Ask your dentist what result is realistic and whether existing restorations could look mismatched afterward. Atlantic Dental Associates of Shallotte can examine discoloration and help you choose an approach based on the cause rather than the shade alone.
