|About Symptoms Diagnosis Treatment|
A dental abscess is a localised collection of pus, (a foul smelling thick white/yellow liquid that is primarily made up of dead white blood cells and bacteria) located within the tooth or surrounding tissues.
Dental abscesses can occur for a number of reasons. Bacteria from a dental cavity descending into the inner part of the tooth and gum, resulting in the body mounting an immune response and walling off the affected area. Trauma can occur as a result of an accident (hit by a car) or biting down on something hard.
FORL lesions – Also known as resorptive lesions, feline resorptive lesions, neck lesions, cavities, cervical line lesions and invasive resorptions, these painful lesions are one of the most common dental problems in cats. Lesions usually begin under the gingival margin and are caused by odontoclasts which are cells whose role is to absorb the bone and roots of deciduous (baby) teeth. In cats withFORL, the odontoclasts reabsorb the adult teeth. Lesions typically occur under the gum line, making early identification difficult. FORL affects the premolars most often, and the cat will display extreme sensitivity if the lesions are touched.
There are three types of dental abscess:
- Gingival abscess – An abscess of the gum tissue.
- Periodontal abscess – An abscess of the gum.
- Periapical abscess – An abscess of the dental pulp.
- Facial swelling
- Draining wound and/or bleeding from the nose or face (below the eye, around the cheeks etc)
- Loose tooth
- Pawing at the mouth
- Loss of appetite and possible weight loss
- Small, round bump in the mouth (on the gums), this is generally paler in colour due to the presence of pus.
Your veterinarian will perform a physical examination of your cat, carefully paying attention to the mouth and face.
In most cases, it will be possible to diagnose a dental abscess during examination. However, a dental xray will be necessary to evaluate the extent of the abscess and the condition of the underlying dental tissue.
The choice of treatment depends on the severity of the abscess.
Drain and clean:
If the underlying tissue is healthy, the veterinarian may drain and clean a small dental abscess. This involves lancing the abscess and draining the pus, then cleaning the pocket, packing with antibiotics and closing.
Root canal treatment:
If the underlying tissue is diseased, root canal may be recommended to save the tooth. The diseased tissue in the centre (canal) of the tooth is removed, the canal is irrigated and then filled with a polymer and sealed with cement.
Your cat will receive sedation, the veterinarian will lance the abscess, flush it with saline extracts the affected tooth.
Your veterinarian will send your cat home with a care sheet, antibiotics, and painkillers, administer as per instructions.
Proper dental hygiene is extremely important not only in preventing dental abscesses but many other dental problems such as gingivitis and periodontal disease. Regularly clean your cat’s teeth with a cat toothbrush and cat toothpaste. Do not use human toothpaste on your cat. Include in his diet raw chicken necks or legs chopped up cuts of cheap beef, these foods help to clean the teeth. Speak to your veterinarian about prescription “oral care” biscuits. Regularly check your cat’s mouth for signs of tartar or dental problems.
