Retained Deciduous Teeth (Milchzähne Fallen Nicht Aus) in Dogs
- Occurrence: common
- Location of illness: Head/Neck
Retained deciduous teeth in dogs are a dental problem where a dog’s baby teeth do not fall out and get replaced by the permanent teeth as they normally should.
The most important facts at a glance
Retained deciduous teeth in dogs are a condition in which the baby teeth do not fall out when the permanent teeth erupt. Normally, the deciduous teeth fall out between the fourth and seventh month of life, but genetic factors, hormonal imbalances, or developmental disorders can disrupt this process. Smaller dog breeds such as Yorkshire Terriers and Chihuahuas are particularly affected. Symptoms often include the presence of double rows of teeth and malocclusion of the permanent teeth. Diagnosis is made by a dental examination and, if necessary, X-rays to assess the structure of the tooth roots.
Treatment usually consists of extraction of the retained deciduous teeth by a veterinarian under general anesthesia to make room for the permanent teeth and avoid future complications. After extraction, careful oral hygiene is important to prevent infection. Orthodontic treatment may be necessary if malocclusion has already occurred. The prognosis is generally good if the teeth are removed early, which can avoid long-term problems.
Prevention includes regular veterinary check-ups and a balanced diet that supports teething. Research focuses on genetic and environmental factors that influence this condition. New imaging technologies and nutritional strategies could improve diagnosis and treatment in the future. Overall, research aims to promote the dental health of dogs and reduce the incidence of problems with retained deciduous teeth.
Causes
Dogs initially have a set of baby teeth, consisting of 28 teeth, which erupt in the first few weeks after birth. These baby teeth are usually smaller and sharper than the permanent teeth. Between the fourth and seventh month of life, they are usually replaced by the permanent teeth, which total 42 teeth. The natural loss of the baby teeth occurs through the pressure of the permanent teeth on the roots of the baby teeth, causing them to be resorbed.
The process of tooth resorption is complex and is controlled by hormonal and physical changes in the dog’s jaw. A disruption in this process can lead to one or more baby teeth not falling out. These retained deciduous teeth can then compete with the permanent teeth for space in the jaw, which can lead to malocclusion and other problems.
The causes of retained deciduous teeth are often genetic. Certain dog breeds, especially smaller breeds such as Yorkshire Terriers, Chihuahuas, and Poodles, are more commonly affected. It is believed that genetic factors can influence the resorption of the tooth roots and the timing of tooth eruption. Hormonal imbalances or developmental disorders in the tooth or jaw area can also play a role.
Another reason may be trauma or infection that disrupts the normal tooth eruption process. Poor nutrition or a lack of certain nutrients during the development phase can also contribute to the problem by affecting the growth and development of the teeth.
Symptoms
The most obvious symptom of retained deciduous teeth is the simultaneous presence of baby and permanent teeth standing side by side in the jaw. This is often the case with canine and incisor teeth.
Dogs with retained deciduous teeth may also show signs of discomfort or Pain, especially when chewing. This can manifest as a reduced appetite or avoidance of chew toys. In some cases, malocclusion of the permanent teeth can occur, leading to an irregular bite.
Other symptoms may include gingivitis, bad breath, or Swelling in the area of the affected teeth. These conditions can worsen if food debris gets trapped between the closely spaced teeth and causes bacterial infections.
Diagnosis
The diagnosis of retained deciduous teeth is usually made by a thorough dental examination of the dog by a veterinarian. This includes visual inspection of the dentition to confirm the presence of double rows of teeth. A veterinarian can also assess the condition of the gums and surrounding structures.
X-rays may be required for accurate diagnosis and to check the root depth of the retained teeth. These help to assess the structure of the deciduous tooth roots and the position of the permanent teeth in the jaw. X-rays are particularly important to determine whether the roots of the baby teeth have been resorbed or whether they are intact.
In some cases, a veterinarian may also perform a blood test to ensure that there are no underlying systemic problems or nutrient deficiencies that could be affecting tooth eruption.
Therapy
The most common treatment for retained deciduous teeth is the extraction of the affected baby teeth by a veterinarian. This procedure is usually performed under general anesthesia to spare the dog pain and stress. Extraction is necessary to make room for the permanent teeth and to avoid future dental problems.
After extraction, it is important to carefully monitor the dog’s oral hygiene to prevent infection. The veterinarian may recommend special dental care or an antibacterial mouthwash to aid healing. In some cases, a follow-up examination may be necessary to ensure that the dog’s dentition develops correctly.
If the retained deciduous teeth have led to malocclusion of the permanent teeth, orthodontic treatment may be necessary. This may involve wearing special braces or appliances to move the teeth into the correct position and restore a correct bite.
Prognosis and follow-up care
The prognosis for dogs with retained deciduous teeth is generally very good, especially if the affected teeth are detected and removed early. Most dogs recover quickly from tooth extraction and show no further signs of discomfort thereafter.
Early treatment usually prevents long-term complications such as gum disease or malocclusion of the teeth. However, if retained deciduous teeth are left untreated, they can lead to serious dental problems that can affect the dog’s quality of life.
Prevention
To prevent retained deciduous teeth, it is important to regularly monitor the dog’s dental and oral health, especially during tooth eruption. Regular check-ups with the veterinarian can help to detect and treat problems early.
A balanced diet that contains all the necessary nutrients for healthy tooth development is also important. Some veterinarians recommend the use of special chew toys or products that support dental health by cleaning the teeth while chewing and promoting gum health.
In addition, dog owners should make sure that their pets do not chew on hard objects that could damage the teeth or disrupt the tooth eruption process. Good dental care at home, including regular tooth brushing, can also help maintain your dog’s oral health and reduce the risk of retained deciduous teeth.
Outlook on current research
Retained deciduous teeth in dogs are a common dental problem that occurs mainly in smaller dog breeds. This anomaly can lead to malocclusion and other oral health problems. Current research focuses on understanding the genetic and environmental factors that contribute to this disorder. Genetic studies have shown that certain breeds, such as Chihuahuas and Yorkshire Terriers, have a higher predisposition to retained deciduous teeth. Researchers are currently investigating genetic markers associated with this condition to improve breeding selection and reduce the incidence of this problem.
Another area of research is investigating the best treatment approaches for retained deciduous teeth. While the traditional approach involves extraction of the affected teeth by a veterinarian, alternative methods such as the use of braces or other orthodontic devices are also being investigated. These methods could help reduce the need for surgery and minimize costs and stress for the animals.
Furthermore, there are studies examining the long-term effects of retained deciduous teeth on the dental health and general well-being of dogs. This research aims to assess the potential risks associated with non-removed baby teeth, such as the increased risk of gum disease, tooth decay, and jaw malformations. By better understanding these risks, scientists hope to develop preventive measures that improve the dental health of dogs overall.
New developments in imaging technology also offer promising opportunities for the diagnosis and treatment of retained deciduous teeth in dogs. High-resolution 3D imaging capabilities allow veterinarians to assess tooth structure and position more accurately, which can lead to better treatment decisions. These technologies are continuously being developed to improve diagnostic accuracy and optimize treatment planning.
Another exciting area of research is the investigation of the effects of nutrition and environmental factors on the development and loss of baby teeth in dogs. Scientists are exploring how certain nutrients and lifestyle factors can affect dental health and whether targeted nutritional strategies can reduce the risk of retained deciduous teeth. This research could lead to new recommendations for feeding puppies to support dental health from the start.
In summary, research on retained deciduous teeth in dogs aims to better understand the causes and develop more effective treatment and prevention strategies. Advances in genetics, imaging, and nutrition offer promising approaches to improving the dental health of dogs and reducing the incidence of problems associated with retained deciduous teeth.
