By the age of 3, a majority of dogs already show signs of periodontal disease — a figure that highlights just how much dental hygiene remains underestimated by many owners.
Why dental health really matters
Beyond bad breath, an untreated dental infection can develop into painful abscesses, tooth loss, or even bacterial spread affecting the heart, kidneys, or liver. For an active or working dog, chronic dental pain can also quietly affect appetite and performance.
Signs to watch for
- Persistent bad breath
- Visible tartar, red or swollen gums
- Difficulty chewing, sudden preference for soft food
- Excessive drooling or repeated muzzle licking
Preventive measures
Regular brushing, with a toothpaste suited for dogs (never human toothpaste, which is toxic to animals), remains the most effective measure — ideally several times a week.
Suitable chew toys help limit tartar buildup through the mechanical action of chewing.
Regular veterinary checkups allow for professional scaling when needed, before the situation worsens.
A particular concern for the working and sport dog
A dog that carries equipment in its mouth (sport bite work, search objects) or must sustain prolonged effort benefits directly from good oral health — dental pain, often subtle, can limit performance without the cause being immediately identified.
