There may be many reasons why a dog’s teeth may turn black, including:
Diet: A dog’s diet contains a large amount of pigments and dyes, and these substances will be deposited on the surface of the teeth, causing the teeth to turn black. .
Dental caries: If your dog does not have good oral hygiene habits, bacteria and food residue on the teeth will form dental plaque, further leading to dental caries. Caries can also cause teeth to turn black.
Oral diseases: Certain oral diseases, such as gingivitis and periodontitis, can cause teeth to turn black. These diseases cause the gums to become inflamed and bleed, which can damage the teeth.
Drugs: Some drugs, such as chloramphenicol and tetracycline, may cause dogs' teeth to turn black. These medications can deposit inside the teeth, causing them to darken.
Age: As the dog ages, his teeth will naturally turn black. If your dog's teeth turn black, it is recommended to take him to the veterinarian for examination to determine the cause and take appropriate treatment measures.
At the same time, good oral hygiene habits are also one of the important measures to prevent tooth blackening. Regular brushing and providing appropriate food and water can also help maintain your dog's oral health.
