What are the common signs of dental disease in dogs?

The common signs of dental disease in dogs include bad breath, swollen gums, tartar buildup, and difficulty eating. Bad breath, often described as halitosis, is a frequent indicator of underlying dental issues caused by bacteria and plaque on the teeth. Swollen gums can signify gingivitis or periodontal disease, which are common problems in dogs, especially as they age. Tartar buildup, which is hardened plaque, can lead to more serious dental diseases if not managed. Difficulty eating may arise from pain or discomfort caused by these dental issues, making it challenging for dogs to chew their food effectively.

In contrast, the other options present conditions that reflect good dental health rather than common signs of disease. Clear breath, strong teeth, and normal eating habits correlate with a healthy mouth, as do bright gums and a lack of tartar. Healthy appetite and clean teeth suggest that a dog's dental health is well maintained, showing no signs of disease. Understanding these differences is crucial for recognizing indicators of dental problems in dogs.
