Dental Disease: Resorptive LesionsI write this as a Veterinary Surgeon who qualified almost twenty five years ago as well as a pet owner. It is only in the past five years that I have developed a keen interest in dental disease in domestic pets. Training in dental problems decades ago was admittedly very basic and, in truth, lacking. This is now changing significantly at the training schools. In a similar way, I believe as owners that our attitude to oral disease in our pets has also fundamentally changed. As owners, we are becoming aware that our pets can and do suffer from painful mouth related illnesses, and that these should be diagnosed and treated as quickly and as effectively as possible.
The first step in reaching a diagnosis should be a thorough Vet check. This may be prompted by something we as owners have noticed, such as a sudden increase in bad breath, or a lack of wanting to play with toys. However, I know all too well how our pets often hide signs of mouth pain and appear fine. Often we as Vets pick up that a dental problem exists at a routine consultation such as a vaccination, or perhaps an unrelated problem such as a lump appearing on one of our animals.
I invariably find that if a dental problem is detected and treated as early as possible in the disease process, then a quicker, more favourable outcome can be achieved. Once treatment has been undertaken, owners will tell me how much happier their pets are, even if there appeared to be no obvious problem before the treatment was carried out. Over the past few years this has become increasingly aided by changes in equipment, in particular with the use of Digital Dental Radiography. We at MK Vet Group are extremely fortunate to have this facility at two of our sites, where it is used on a daily basis.
I often find myself quoting statistics to clients, such as two-thirds of animals over three years of age will have some form of dental disease. Yet on reflection I don’t find this particularly helpful. For example, if you have three pets, this does not mean that two of them will have dental disease. What I do find relevant with these statistics is simply to say that that dental disease is extremely common; it is not limited to elderly pets and often is present despite our animals seeming to be fine.
A typical case presented to me recently. An appointment was made for a relatively young cat as the owners had noted a swelling. This swelling was found to not require any treatment; however during the routine examination significant redness of the gums was noted throughout the mouth. It was discussed and agreed to examine this cat’s mouth fully under a general anaesthesia. Only then was it found that this cat suffered from a condition known as Type I/II tooth resorptive lesions affecting several teeth. This is a progressive and typically painful disease. The only effective treatment is extraction, which was carried out without complication.
The radiograph on the right shows three teeth in the lower jaw. The tooth to the left shows a normal healthy tooth. The tooth on the right shows the loss of the majority of the crown of the tooth, with the roots being actively converted to bone tissue similar to the normal jaw bone. The central tooth shows this condition in the early phases with a large, painful lesion seen – the black “hole” visible on the right side of the crown of the tooth. This condition would not have been diagnosed without the use of radiographs.
It is expected that this cat will make an excellent recovery and, rather than having difficulty eating with missing teeth, will now genuinely eat better than before for the simple reason that a painful disease process was recognised and treated promptly.
Steve Bonthorne BVSc (Sydney) MRCVS - Steve has been with MKVG since 2007 having qualified in Australia in 1992. Over the past few years, he has developed a strong interest in dental disease and its treatment. All too often he finds this disease can go undetected and can often be painful and debilitating, but also responds very well to treatment, giving our pets a much better quality of life.
