Why do dogs' teeth turn black? - in detail

Dogs' teeth can turn black due to several reasons, each of which is influenced by various factors. The primary causes are tartar buildup and the presence of bacteria.

Tartar, also known as dental calculus, is a hardened deposit that forms on teeth when plaque is not removed. Plaque itself is a colorless film of bacteria that coats the teeth. If left untreated, plaque can mineralize and transform into tartar, which appears yellow or brown initially but can darken over time. Tartar buildup is more likely to occur in dogs due to their dietary habits and lack of regular dental care compared to humans.

Bacteria play a significant role in the discoloration process. Certain types of bacteria produce pigments that contribute to the blackening of teeth. For example, Porphyromonas gingivalis, a bacterium associated with periodontal disease, can produce a dark pigment called porphyrin. This pigment can stain the teeth and gums, giving them a black or dark appearance.

Other factors that contribute to tooth discoloration in dogs include genetics, age, and overall health. Some breeds may be more predisposed to dental issues due to their genetic makeup, while older dogs are more likely to have tartar buildup as a result of years without proper dental care. Additionally, underlying health conditions such as kidney disease can affect the appearance of teeth by altering the mineral composition and causing discoloration.

Regular dental care is essential for maintaining the health and appearance of dogs' teeth. This includes brushing their teeth with dog-specific toothpaste, providing dental chews or toys designed to help remove plaque, and scheduling professional cleanings with a veterinarian when necessary. By addressing the underlying causes of tartar buildup and bacterial growth, pet owners can prevent or reverse the blackening of their dogs' teeth.
