Bacteria and food particles accumulate on teeth, which can create a sticky substance called plaque. Plaque can usually be removed with regular brushing. However, if it isn’t removed properly and relatively quickly (within 2-3 days), plaque can turn into tartar. Tartar is much harder to clean than plaque and needs to be removed safely through professional cleaning. Although tartar is normally more yellow in color, it can appear colorless and can be hard to detect. Tartar can lead to cavities, gum disease, tooth decay, or other oral health concerns if it is not removed.
