Do Dogs Teeth Fall Out: Normal Loss vs Dental Disease
Do dogs teeth fall out is a question with two very different answers depending on the dog’s age. Do dogs lose teeth as puppies? Yes — this is a completely normal part of development. Dogs teeth falling out in an adult dog, by contrast, is almost always a sign of dental disease and warrants veterinary evaluation. Understanding when do dogs lose their teeth as a normal process versus when dogs losing teeth signals an underlying problem helps you respond appropriately.
Normal Puppy Tooth Loss
When Do Dogs Lose Their Baby Teeth
Do dogs lose teeth as puppies between 3 and 7 months of age as their adult dentition comes in. Puppies have 28 deciduous (baby) teeth that are gradually replaced by 42 permanent adult teeth. Dogs teeth falling out during this period is expected and normal — you may find tiny teeth on the floor, in bedding, or in toys. Most puppies swallow their baby teeth without noticing, which is harmless.
The order of loss roughly follows the order of eruption: incisors first (around 3 to 4 months), then canines (4 to 6 months), then premolars and molars (4 to 7 months). By 7 months of age, all adult teeth should be present in most breeds.
Retained Baby Teeth
A problem arises when do dogs teeth fall out on schedule does not happen — when baby teeth remain alongside the adult teeth that have already erupted. Retained deciduous teeth are most common in small breeds like Yorkshire Terriers, Chihuahuas, Maltese, and Pomeranians. Dogs losing teeth in the proper sequence is important because retained teeth cause crowding, abnormal bite alignment, food trapping, and accelerated periodontal disease in the affected areas.
Retained baby teeth should be extracted by a veterinarian — they do not fall out on their own and cause ongoing dental problems if left in place.
Adult Tooth Loss: Dental Disease
Why Adult Dogs Lose Teeth
Do dogs teeth fall out in adults for different reasons than puppies. Dogs losing teeth as adults almost always reflects periodontal disease — the destruction of the ligament and bone that anchor the tooth in the socket. As the supporting structures deteriorate, the tooth becomes loose and eventually falls out or requires extraction.
Periodontal disease is the most common health condition in adult dogs, affecting the majority by age 3. Early stages show red, inflamed gums. Advanced stages show bone loss, deep pockets, exposed roots, and do dogs lose their teeth becomes a concrete rather than theoretical concern.
Other Causes of Adult Tooth Loss
Dogs teeth falling out in adults can also result from:
- Tooth fractures from chewing on very hard objects (whole elk antler, rocks, bones)
- Trauma to the face or jaw
- Oral tumors pushing teeth out of position
- Severe nutritional deficiencies (rare in dogs on complete commercial diets)
Any loose tooth in an adult dog is a signal for veterinary evaluation — even a tooth that falls out cleanly likely indicates underlying disease at neighboring teeth or throughout the mouth.
Prevention of Adult Tooth Loss
Preventing do dogs teeth fall out scenarios in adult dogs comes down to consistent dental care:
- Daily or near-daily tooth brushing to prevent plaque buildup
- Annual professional dental cleanings under anesthesia
- Avoiding excessively hard chews that cause tooth fractures
- Dental diets or dental chews approved by the Veterinary Oral Health Council (VOHC) as adjuncts to brushing
Bottom Line
Dogs losing teeth as puppies between 3 and 7 months is normal development. Adult dogs losing teeth is a sign of preventable dental disease — regular brushing, annual professional cleanings, and avoiding tooth-fracturing chews are the best tools for keeping adult teeth in place throughout the dog’s life.
