Causes Of Staining
Extrinsic And Intrinsic Stains
Your teeth are made of layers: the enamel, the dentin, and the pulp.
- The enamel is the incredibly hard outermost part of the tooth that shows to the world. This is the part that is addressed during a whitening treatment. This area may be stained with food, drink, or tobacco stains, all of which can be removed with professional tooth whitening. All of the stains on this outermost part of the tooth are called extrinsic stains. Despite how it may appear, the enamel is slightly translucent instead of solid white.
- The dentin is the layer under the enamel, and this layer is slightly more yellow and softer than the enamel. Because the enamel is slightly translucent, the dentin of the teeth can be seen a little bit, although it typically just appears as white underneath the enamel. If this layer of dentin has any discolouration, however, it can show through the enamel and make the tooth appear stained. This is called an intrinsic stain, as it is a stain within the tooth.
- Finally, there is the pulp layer, which contains nerve endings. This layer of the tooth does not show and will not affect the appearance of the tooth.
Some Medication Induced Stains
Some forms of medication, including some types of antibiotics, can lead to discolouration in the structure of the teeth over time. While this staining is not an indicator of negative health impacts, the stains are not removable since they are happening in the dentin of the tooth instead of on the outermost layer. Sometimes the tooth discolouration will go away if the type of medication is switched or is otherwise no longer in use.
Damaged Teeth
Internal damage or decay is not something that can be removed with whitening. Because it is an internal issue, surface-level cleaning will not fix it. If your tooth is discoloured on the inside, it can be an indication of other oral or medical issues and you should schedule a dental exam to assess the damage. Sometimes damaged teeth and staining go together, as people who smoke often have tobacco stained teeth that are easily cleaned, however, smoking that causes tooth and gum disease may also cause intrinsic staining that cannot be cleaned.

FAQ
