Retained Deciduous Teeth in Dogs and Cats: The 2026 Extraction Guide
Just like humans, puppies and kittens are born with a temporary set of teeth. These deciduous (baby) teeth are supposed to serve a short-term purpose, eventually shedding as the root is absorbed to make way for the permanent adult teeth. But what happens when the baby tooth refuses to vacate the premises?
This condition, known as a retained deciduous tooth, is remarkably common—especially in small and toy dog breeds, though it can occur in large breeds and felines as well. Ignoring a "double tooth" can lead to severe orthodontic shifting, chronic pain, and early-onset periodontal disease. Here is how to navigate this common pediatric dental issue.
The Orthodontic Impact Matrix
A retained baby tooth is not merely an aesthetic quirk; it actively undermines the structural integrity of your pet's mouth. Here is the breakdown of exactly how these stubborn teeth cause damage.
| The Complication | Biological Mechanism | Long-Term Result if Untreated |
|---|---|---|
| Severe Dental Crowding | Two teeth occupy the space intended for one, forcing the permanent tooth to erupt at an abnormal angle. | Malocclusion (bite misalignment), preventing the mouth from closing fully or comfortably. |
| Periodontal Disease | The tight, unnatural crevice between the baby and adult tooth traps hair, food, and plaque that cannot be brushed away. | Rapid tartar buildup leading to gum recession, bone loss, and premature loss of the adult tooth. |
| Palatal Trauma | Misaligned lower canine teeth are pushed inward, directly striking the roof of the mouth. | Chronic pain, ulceration of the hard palate, and potential development of an oronasal fistula. |
4 Actionable Steps for Managing Retained Teeth
By six months of age, virtually all of your pet's deciduous teeth should have fallen out, and their adult teeth should be firmly in place. Around the 5-to-6-month mark, you should be doing weekly visual inspections of their mouth. Pay special attention to the upper and lower canines (the "fangs"), as these are the most notoriously stubborn deciduous teeth in both cats and dogs.
A deciduous tooth that looks "wobbly" might tempt you to yank it out with your fingers or a vigorous game of tug-of-war. Resist this urge. The root of a puppy or kitten's canine tooth is often longer than the visible crown. Pulling it manually can easily snap the crown off, leaving the root embedded in the jawbone. This leads to intense pain, hidden abscesses, and a complex surgical extraction later.
If your pet reaches six months old and still has retained baby teeth, extraction is medically necessary. To save on costs and spare your pet from undergoing anesthesia twice, it is standard veterinary protocol to remove stubborn deciduous teeth during their routine spay or neuter procedure. Always ask your vet to do a thorough dental check while your pet is under.
Following a surgical extraction, the empty socket needs time to heal. Your vet will likely prescribe pain medication. You must transition your pet to canned wet food or thoroughly soak their dry kibble in warm water for at least 7 to 10 days. Withhold all hard chew toys, tennis balls, and tug ropes during this period to prevent tearing the delicate sutures.
The Verdict: Proactive Dental Defense
A retained deciduous tooth is a ticking clock for your pet's oral health. By knowing what to look for and collaborating with your veterinarian around the six-month mark, you can prevent a minor orthodontic hiccup from turning into a lifetime of dental disease and discomfort.
