Dental Month – Fractured teeth
Fractured teeth are a common injury in cats and dogs, with the majority involving fractured canines of the upper jaw. Damage is commonly caused by falls, running into objects, clashing teeth and road traffic accidents. In dogs, other objects that can damage teeth include raw hide, bones, sticks/branches, rocks, ice and other hard objects.
The radiograph to the right shows a case of pulpitis in a cat. The pulp cavity is the hollow area inside a tooth filled with sensitive pulp tissue (blood vessels, nerves and connective tissue). This commonly occurs when the tip of the tooth is fractured, allowing bacteria to enter the pulp cavity. Swelling of the pulp tissue prevents blood entering the root canal and the result is ‘death’ of the tooth. On the radiograph we can see widening of the pulp cavity compared to the normal tooth on the right, with evidence of an abscess at the apex of the root. On this occasion the affected tooth was extracted. It is important to note that this problem was found during a routine dental, and the patient did not show any obvious mouth pain at the time, but the owner reported marked improvement in his demeanour and appetite following surgery. Due to high pain threshold and other instinctive behaviours, our patients rarely shows signs of pain and will often hide pain very well.
It is therefore important to never ignore a broken tooth in your pet.
