Tooth resorption

Tooth resorption is a common and painful condition affecting cats of all ages and it can occasionally affect dogs too.

The underlying cause is yet unknown, it is not related to build up of tartar and cannot be prevented by dental hygiene.

Resorption of the tooth begins in the root around the gum line. The root is eroded and gradually dissolves. This resorption continues inside the crown of the tooth, weakening the enamel and resulting in exposure of the sensitive nerves leading to pain.

Some cats will show signs of dental pain including reluctance to eat especially hard biscuits, salivation or sensitivity to the jaw being touched.  However, many cats will show no obvious signs of pain and seem to eat as normal – some will even gobble their food to avoid chewing so may be seen as eating more than usual!

Tooth resorption can often be recognised on routine examination as a small area of pink at the gum line. When the vet spots this tell-tale sign, they will recommend your cat has an examination under general anaesthetic so that x-rays can be taken to assess the full extent of the disease

These images of Mulberry House patients show how important dental xrays are – a very subtle lesion seen on the tooth can have a large erosion underneath.

The diseased teeth will need extracted and the xrays will show the vet whether the entire roots need to be extracted or only the painful crown removed.
