When a tooth looks loose, broken, worn down, or discoloured, it is easy to focus on what can be seen on the surface. In many cases, though, the visible change is only part of the problem. A damaged tooth may already be painful, infected, unstable, or affected below the gumline in ways that are not obvious from the outside.
That is why changes in the appearance of a tooth are worth taking seriously, even when your pet is still eating.
A loose tooth may indicate advanced periodontal disease, loss of supporting bone, trauma, or another process affecting the structures that hold the tooth in place.
A broken tooth may expose sensitive inner tissue, allow infection to travel into the pulp and root, or create sharp surfaces that irritate the mouth. Even when the fracture looks small, it may still be painful.
A discoloured tooth may suggest previous trauma, internal damage, pulp death, wear, or chronic disease affecting the tooth. Teeth that look grey, pink, brown, or otherwise abnormal should not be assumed to be harmless.
Pets can continue eating despite significant dental pain, particularly when the problem has developed gradually. Some will adapt by chewing on one side, preferring softer food, dropping food, or avoiding certain treats. Others may show very few signs apart from the visible change in the tooth itself.
Because of that, a tooth that “doesn’t seem to bother them” can still be a source of ongoing pain or infection.
Loose, broken, or discoloured teeth may be associated with periodontal disease, trauma, chewing on hard objects, fractured teeth, tooth root infection, retained roots, and other dental problems.
In cats, resorptive disease can also cause significant damage to teeth that may not be fully appreciated without dental x-rays. In both dogs and cats, what is visible above the gumline does not always reflect the full extent of disease.
Alongside changes in the tooth itself, some pets may also have bad breath, tartar, red gums, drooling, pawing at the mouth, food dropping, chewing on one side, or sensitivity when the mouth is touched.
Some pets develop facial swelling or become suddenly more uncomfortable if infection or tooth root disease is present.
Any loose, broken, or discoloured tooth is worth having assessed. This is especially important if your pet seems painful, has bad breath, is chewing differently, or if the tooth appears fractured to the point that the inside of the tooth may be exposed.
The goal is to determine whether the tooth is stable, whether infection or pain is likely, and whether the tooth may be treatable or needs to be removed.
An initial assessment involves examining the mouth as far as your pet will comfortably allow while awake. This helps identify visible tartar, gum disease, obvious fractures, looseness, and any other signs that a more significant problem may be present.
If dental disease or tooth pain is suspected, a professional dental procedure under anaesthetic may be recommended. This allows the tooth to be assessed properly, the surrounding tissues to be examined, and dental x-rays to be taken to evaluate the roots and supporting bone below the gumline.
With damaged teeth, much of the important information lies below the surface. A tooth may look only mildly affected from above but have root infection, internal damage, or supporting bone loss underneath.
Dental x-rays help us determine how serious the problem is and what treatment is most appropriate. They are often essential when deciding whether a tooth can be left alone, monitored, or needs to be extracted.
More urgent assessment is sensible if your pet has a freshly broken tooth, visible bleeding, facial swelling, sudden pain, refusal to eat, or a very loose tooth. These situations can involve significant pain or infection and should not be left too long.
If you have noticed a loose, broken, worn, or discoloured tooth in your dog or cat, we can help assess what it may mean and whether treatment is likely to be needed.
