Two Different Types of Tooth Stains
There are two different types of tooth stains as related to teeth: Extrinsic Staining and Intrinsic Staining.
Extrinsic staining result from external factors such as coffee, red wines, tea, foods and drinks that are dark colored, tobacco and routine deterioration. Essentially, they are a natural part of life however nonetheless they are unsightly and can be removed. Superficial extrinsic staining can be removed with good hygiene techniques such as regular brushing and dental check-ups with dental cleanings. More stubborn stains are removable with more involved initiatives like teeth bleaching or whitening.
According to the FDA, the difference between bleaching and whitening is usually that the term “bleaching” is allowed to be used only when the teeth can be whitened beyond their natural color and when the used product contain bleach. Whitening is a process that identifies restoring a tooth’s surface color by getting rid of debris and dirt.
Intrinsic staining occurs much deeper in teeth than extrinsic stains, forming in the interior of teeth. They sometimes result from trauma, natural aging, contact with minerals (like tetracycline), during tooth formation and excessive ingestion of fluorides.
