Halitosis is the fancy word for bad breath, and that odor is nearly always a sign of a bigger problem. Just this week, I noted a slightly foul odor coming from my own little girl, Dharma. On closer inspection, I noted that the very top of her canine tooth is beginning to turn brown. Overall, the tooth and gumline appear pretty much normal, but I am suspicious of a tooth root infection lurking below.
As in Dharma’s case, the cause of halitosis is most often attributed to dental disease, but there are many other sources of odor that should be considered and put on your mental checklist. These can include:
Diseases of the mouth, in addition infection of gums and teeth, your “basic” dental disease:
Halitosis is a diagnosis that is easily made: Just smelling your dog’s breath at home is the first step. If there is a disagreeable odor, halitosis is present, and there’s a problem. As the list above illustrates, a full spectrum of potential sources of “yuck mouth” exist, and interestingly, as varied as these potential causes can be, sometimes the first clinical sign observed in many of them is odor.
If the diagnosis is not obvious from a peek in the mouth (such as a bad tooth), further steps will be needed check for other disease. Once the reason of the bad breath is discovered, therapy can then be directed at correcting the cause.
The major take-away message is that halitosis is not a disease in of itself, but a sign of disease. While bad breath generally indicates an unhealthy mouth, there are many other potential causes to consider, and evaluation of this symptom by your veterinarian is recommended.
