"What do you look for during a dental exam?"
February is dental month at Bishop Ranch Veterinary Center & Urgent Care! Ever wonder what we look for when we ask your pet to say “ahhhh”? Below, I will go over some of the more common things that affect the teeth of cats and dogs. I recommend owners perform their own at-home evaluations of their pet’s teeth on a monthly basis – if you see any of these things, bring your pet in so we can discuss what the best next steps would be.
At-home oral exams are always a good idea
To do an oral exam, the best way to start is to look at the teeth from the side. The easiest way is to pull the corner of your pet’s lips back with your thumb while holding the upper lip up with your other hand. Check all the teeth and the gums (if they are darker pink or red along the tooth, it’s a sign of gingivitis). The worst disease is usually on the teeth all the way in the back of the mouth so make sure to take a look there. Once you’ve looked at both sides, open the mouth to look at the tongue, lips and back of the throat for any abnormal growths or masses.
Tartar and calculus
The rough, raised yellow and brown material sticking to your pet’s teeth are tartar and calculus. These are the primary indicators we look at to determine if your pet has periodontal disease. Follow this link to read more about the most common disease affecting both dog and cat mouths.
Discolored/abnormally colored teeth
The vast majority of discolored teeth are dead, which result from either trauma or infection. The discoloration you see is actually from bleeding inside of the tooth, which results in a color change from the normal white to pink, purple or brown.
Fractured (broken) teeth
The most commonly broken teeth are the canine teeth (in dogs and cats) and the upper fourth premolar (carnassial) teeth (in dogs). Broken teeth are most often the result of chewing on hard objects (such as bones or rocks) but can also be seen with trauma. When the tooth breaks, the root canal is exposed, which causes a significant amount of pain. It also allows bacteria to enter and infect the tooth. Down the road, this can cause a tooth root abscess or infection of the tooth root.
Retained baby teeth
These are most commonly seen in small and toy dog breeds as well as in brachycephalic breeds such as bulldogs and pugs. For some reason, in these breeds, the baby teeth do not fall out. They will instead stay where they are, which leads to two problems:
1) It may cause the adult tooth to erupt at an abnormal angle, causing a malocclusion (misalignment of the teeth).
2) The placement of the adult and baby tooth provide the perfect conditions for plaque/tartar accumulation, leading to severe periodontal disease and eventually the loss of both teeth.
One of the reasons we recommend waiting to spay or neuter until 6 months of age is because at that time we can determine if we also need to remove any retained baby teeth.
Seen as widespread severe oral inflammation of the gingiva (gums) and back of mouth, feline stomatitis is a frustrating disease to treat. It is extremely painful – cats may have difficulty eating, drool, groom less, or be less social. Unfortunately, the exact cause of stomatitis is unknown, however a common theory is that the cat’s immune system is having an over-reaction to the bacteria within plaque. Therefore, treatment is aimed at keeping plaque levels as low as possible, via regular, thorough dental cleanings (removal of plaque above and below the gumlines), as well as other medications to manage the immune response. In some cases however, full-mouth extractions are the only thing that bring these cats relief.
Feline Oral Resorptive Lesions (FORLs)
In a recent study, 72% of cats over 5 years of age had at least one of their teeth affected by this disease. Odontoclasts (cells that are responsible for resorbing/eating away the bone) are activated, causing erosion/loss of the tooth. They most commonly occur at or just below the gumline. They are extremely painful – when lightly touched, jaw spasms or teeth chattering can be seen. Dental x-rays are very important with these cases, as it determines how we treat them.
