What are the methods for whitening teeth?
Disease description:
In daily life, I sometimes drink coffee when I'm bored, which has caused my teeth to become yellow. Brushing doesn't seem to help. What are some ways to whiten teeth?
Methods for whitening teeth include cold light whitening and dental cleaning. Cold light whitening can improve tooth yellowing caused by intrinsic staining, thereby achieving a teeth-whitening effect. Dental cleaning helps address tooth discoloration resulting from long-term smoking or consuming highly pigmented foods, which leads to pigment buildup on the teeth.
