Tooth resorption occurs when the structure of the teeth under the gums erode or collapse, leading to serious oral damage, and it can happen to felines too! Here, our Los Angeles veterinarians discuss the symptoms of tooth resorption in cats, the different types, and how to get it treated.
Tooth Resorption in Cats
Tooth resorption is when the hard tissue underneath the gums of the teeth erodes. If left untreated, it can cause irreparable damage.
Cats develop tooth resorption when their bodies start breaking down and absorbing the structures that form their tooth. Generally, this condition starts in the enamel and makes its way to the tooth's center. Eventually, most of the tooth will be completely gone. The premolars in the lower jaw (generally the third premolars) are the teeth that are most often affected.
Tooth resorption is one of the most common dental conditions seen in cats and is a painful experience for your feline friend. That's why it is important to bring your feline friend to the vet for routine dental exams and cleanings so your vet can catch the condition as early as possible.
Different Types of Tooth Resorption in Cats
There are two types of tooth resorption that cats can develop. The type your cat has will be determined by the way the tooth appears on the radiograph (X-ray) your vet takes to diagnose this condition. When a veterinarian takes a radiograph of a normal tooth it should show the tooth root with a thin dark outline surrounding it, that separates the root from the bone. The dark outline represents the periodontal ligament, which is a normal anatomic element that connects the bone and the root.
The causes of both types of tooth resorption in cats are unknown. However, maintaining good oral hygiene practices and regular professional oral examinations and cleanings is your cat's best chance of preventing this condition, or detecting it right away.
Here are the two types of tooth resorption in cats:
Type 1 Tooth Resorption
When cats have type 1 tooth resorption, it means the tooth's crown is damaged, but on the radiograph, the root looks normal and the periodontal ligament can be easily recognized.
Type 2 Tooth Resorption
Also referred to as replacement resorption, this is where the root looks like it is disintegrating, making it hard to differentiate from the bone on the radiograph.
Symptoms of Tooth Resorption in Cats
While tooth resorption can be very painful for cats, it can be hard to recognize because our feline companions are very good at masking their pain. This makes it very important to be able to recognize the common signs and symptoms listed below:
- Increased Salivation
- Difficulty Eating
- Oral Bleeding
- Behavioral Changes
How Cats With Tooth Resorption Can Be Treated
If you think your cat may have tooth resorption you should call your vet as quickly as possible. If your veterinarian suspects your feline friend has this condition, they will conduct radiographs and a clinical screening while your cat is under anesthesia. Your vet may also perform a complete dental screening. Without these tests, your cat's tooth resorption will go undiagnosed and continue to get worse, causing your kitty a great deal of pain.
If your vet diagnoses your cat with type 1 tooth resorption, they will most likely need to extract the root and crown. If your cat has type 2 tooth resorption, your vet may need to conduct a crown amputation with intentional root retention.
