My Dog’s Baby Teeth Are Not Falling Out

My dog's teeth are not showing

See files for Dogs

You may not realize that dogs do milk teeth. As your puppy matures, his teeth will change in a similar way to humans. A dog’s baby teeth, also known as baby teeth, primary teeth, or milk teeth, are smaller and sharper than adult teeth. They should naturally fall out on their own as their adult teeth develop. However, there may be cases where puppies have young teeth left. We may notice it at first because the adult teeth growing under them cause discomfort and pain.

In AnimalWised we find out why my dog’s baby teeth are missing. We will tell you more about the process of developing adult teeth and what we can do to make the process easier if there is a problem.

The arrangement and condition of a set of teeth is called the dentition. There are two types of dentition in canines:

  • Deciduous or primary dentition: commonly known as baby teeth, which consist of 28 individual teeth.
  • Permanent or permanent dentition: Once all adult teeth have developed, 42 teeth should be present.

A dog’s baby teeth may look similar, but upon closer inspection they are quite different from adult teeth. Dentition differs in arrangement and quantity, but individual teeth also differ. Baby teeth in dogs are sharper and have a different shape than adult teeth.

There are a variety of reasons why a puppy’s teeth are so sharp. First, because the mother is weaning her puppies, when they develop sharp teeth, they start to hurt the mother nipples. This helps to signal to the mother that it is time for them to stop nursing and start eating solid food. They are also useful in helping puppies learn to bite each other.

The replacement of the primary dentition with the permanent dentition begins approximately in the third month of life. This process should end between 6 and 7 months of age. If you’re wondering why your puppy’s baby teeth haven’t fallen out and they’re younger than this age range, you’ll need to be patient. If after this time the milk teeth still remain in the puppy’s jaws, we should start thinking about the problem.

Poor dental development is not the only problem that can affect a dog’s mouth. Read more in our article on why dogs’ gums bleed.

When adult teeth do not develop into 7 months of age, we will probably see that the dog has adult and baby teeth at the same time. This has to do with how adult teeth develop. As the puppy matures, the adult teeth cut under the baby teeth and push them out of the bed. The adult teeth should then sit comfortably in the dog’s jaw.

If the baby teeth do not fall out, the adult teeth will still grow. This can be very painful for a young dog. While this can happen to any breed or type of dog, it is something that most often happens to small or toy dog ​​breeds. The teeth are most often affected canines (fangs), followed by incisors and premolars. If your dog does not lose milk fangs, this will be a problem.

The reason why a puppy’s milk teeth do not fall out is most often one of the following:

  • Adult teeth grow in the wrong direction: when an adult tooth does not grow properly, it does not exert enough pressure on the root of the baby tooth. This means that it is not reabsorbed and a double line of teeth can be seen.
  • Migration of the permanent tooth germ: a tooth germ is a collection of cells that form in the embryonic period to give rise to a future permanent tooth. When this germ migrates to an abnormal position, it will not press on the root of the baby tooth and it will not fall out.
  • Dental agenesis: congenital absence of one or more teeth due to insufficient formation of the tooth germ during the embryonic period. Since there is no permanent tooth, it will not put pressure on the baby tooth and cause it to reabsorb.

It is worth noting that it is necessary to distinguish the persistence of milk teeth polyodontics. A larger number of teeth in the oral cavity of dogs is also observed in polyodonty. In this case, it is not due to the persistence of milk teeth, but rather to the fact that there is a greater number of permanent teeth.

Once a dog’s adult teeth have grown in, they are still susceptible to damage. Read more in our article on why my dog’s teeth are rotten.

The persistence of milk teeth predisposes to the occurrence of various oral pathologies:

  • Periodontal disease: the coexistence of both types of teeth promotes the deposition of bacterial plaque and tartar. If left untreated, it can cause premature periodontal disease in dogs with gingivitis and periodontal disease.
  • Painful malocclusion: the persistence of milk teeth prevents the correct placement of permanent teeth. This in turn causes inadequate occlusion between the upper arch and the lower arch.
  • Gum, palate and teeth injuries: misalignment of teeth causes repeated trauma that can injure the oral mucosa and teeth.
  • Fractures of teeth: tooth misalignment causes abnormal wear that weakens them and predisposes them to fracture.

As soon as we see that our dog’s milk teeth have not fallen out when they should, we must take them to the vet. They will either be able to diagnose the problem themselves or send a referral to a specialist. Any remaining baby teeth will need to be removed as soon as possible, most often under general anesthesia.

Oral surgery to remove baby teeth in dogs is often complicated fractures teeth. This can lead to tooth debris remaining in the gums, as well as injury to the adult teeth underneath. For this reason, it is vital that a veterinarian specializing in canine dentistry carries out the process.

Extraction of baby teeth in dogs should be done as soon as possible. The chances of the permanent teeth shifting into the correct position decrease over time and orthodontic treatment will be necessary. In addition, delaying the extraction will gradually worsen the symptoms associated with persistent baby teeth.

Finally, it is important to consider the following recommendation. Until your dog’s primary dentition is completely replaced, it is important to monitor the development of the adult dentition. Watch out for any malocclusion or other problems we described above. If we see a problem, don’t hesitate to take them to the vet. Once the tooth replacement is complete, remember the importance of canine oral hygiene. Brush your dog’s teeth every 2-3 days and use products designed specifically for dogs.
