Definition, prevalence & Causes
Tooth resorption is a widespread condition where the body begins to break down and absorb the structures of the tooth. This process starts with the dentin, the main component of the tooth, and can eventually affect the entire tooth from root to crown.
It is common in both cats and dogs, with a higher prevalence in older cats, impacting up to two-thirds of cats over the age of six. While less frequently reported in dogs, they can also experience this condition. The exact cause of tooth resorption is unknown, and currently, there are no preventive measures. It is often progressive, leading to significant discomfort and dental health issues.
Clinical signs, diagnosis & treatment
Tooth resorption can be extremely painful, though pets often hide their discomfort. Signs in cats include a preference for soft foods, increased salivation, pawing at the mouth and visible changes in tooth colour or structure. Behavioural changes, like increased irritability or withdrawal, may also indicate pain.
Diagnosis involves visual inspection, tactile examination and dental radiographs, which determine the extent of the damage and the type of resorption. In cats, two types are identified: Type I, requiring full extraction, and Type II, where the tooth may be replaced by bone and involves a different extraction technique.
Radiographs & Follow-Up Care
Dental radiographs are essential for diagnosis and planning treatment for tooth resorption. They provide a detailed view of the affected teeth, helping to determine whether full extraction or crown amputation is necessary.
We recommend follow-up radiographs every 6-12 months to monitor new developments in pets with tooth resorption.
This painful condition requires prompt and effective treatment to prevent further complications. Early detection and intervention can significantly improve the quality of life for affected pets by reducing pain and limiting severity.
