Tartar, also known as calculus, forms in your dog's mouth when plaque—a soft, sticky substance—builds up on the teeth. If plaque is not removed, it hardens over time due to minerals in the dog ...
In dentistry, calculus or tartar is a form of hardened dental plaque. It is caused by precipitation of minerals from saliva and gingival crevicular fluid (GCF) in plaque on the teeth . This process of precipitation kills the bacterial cells within dental plaque, but the rough and hardened surface that is formed provides an ideal surface for ...
One of the main aims of dental food for dogs is to minimize plaque accumulation and gingival inflammation. [2] The oral cavity of dogs can be exposed to a variety of bacteria, parasites and viruses from their environment and it is not surprising that these induce an inflammatory reaction in the periodontium.

Before the cavity forms, the process is reversible, but once a cavity forms, the lost tooth structure cannot be regenerated. A lesion that appears dark brown and shiny suggests dental caries were once present, but the demineralization process has stopped, leaving a stain. Active decay is lighter in color and dull in appearance. [14]
A human with red-green color blindness will mistake one color for another. For example, black may be perceived as shades of red, while bright green could be identified as yellow, Healthline reports .
Dog treats are often given to pets as a reward or just to let them chew on a bone, which works their jaw muscles and helps keep their teeth clean. [67] Although dog treats carry high benefits for dogs' teeth, they can also be a source of problems like obesity when given excessively, especially human table scraps.
In humans, the upper canine teeth (popularly called eye teeth, from their position under the eyes [1]) are larger and longer than the lower, and usually present a distinct basal ridge. Eruption typically occurs between the ages of eleven and twelve years for upper canines and between nine and ten years for lower canines.
One version produces yellow dogs and a mutation produces black dogs. All dog coat colors are modifications of black or yellow. [21] For example, the white in white miniature schnauzers is a cream color, not albinism (a genotype of E/E' at MC1R). Modern dog breeds exhibit a diverse array of fur coats, including dogs without fur, such as the ...
