Puppy Teeth

You have added a puppy to your family and want to do all the right things assuring you will have a healthy, happy and well-mannered pet. Your decisions on caring for your dog will dramatically affect the quality of your puppy’s physical health, mental well-being, and behavior. Traditionally over the next several months owners need to ensure their pet is properly immunized, is free of internal and external parasites, is getting the right food and supplements, and is growing properly, particularly their teeth.

One area that requires close monitoring is the growth and development of the puppy’s mouth and teeth. This is an area of the body where things can change very rapidly and if a problem goes unnoticed for some time, there may be permanent damage. Puppy teeth fall out allowing for their permanent teeth to develop correctly. Puppies are usually eight to twelve weeks old when they are taken to their new homes. Puppies should have a full set of primary or deciduous (baby, milk) teeth by the age of three months, these puppy teeth fall out over the next 4 months. Nevertheless if the deciduous tooth fails to develop by twelve weeks of age, it is likely the permanent tooth that should follow will not develop either.
Each quadrant of the mouth should have three incisors at the front, one long sharp canine tooth and then three pre-molar teeth behind the canines. As puppy teeth fall out owners should check their dog’s bit to ensure their puppies permanent teeth are coming in properly. Although puppy teeth fall out naturally a dog may benefit considerably from a tooth extraction to relieve malocclusion. Owners who monitor the proper schedule for their puppy’s teeth to fall out can avoid the conditions of crowded teeth; misaligned teeth; crossbite, overbite, underbite, open bite.

Puppy Teeth Time Line

28 primary(deciduous) teeth erupt, these teeth are all visible and It is important that all 28 teeth eventually fall out creating room for 42 permanent teeth . Dogs do not have molars during this period of tooth development, therefor the primary area of concern during the first 4 months is the front of the dog’s mouth. Puppies chew to relive the pain of teething. It’s important to keep a variety of things you want her to chew within reach of her mouth at all times. Chewing also releases endorphins in the puppy’s body, for this reason it is important dogs learn acceptable behaviors for what they can chew for pleasure later in life.
The incisors begin to fall out and the permanent incisors erupt this begins a stage when the dog has both deciduous and permanent teeth. A typical dog has six incisors on each of the lower and upper jaws. A dog’s body absorbs the roots of the puppy teeth as they fall out. Dog owners should be looking for signs of retained teeth at this stage, these signs include difficulty eating, swollen, red, bleeding gums around baby teeth, or abnormally-positioned permanent teeth.
The canines begin to fall out and the permanent canines erupt. The molars begin to erupt there are four premolars on each of the upper and lower jaws located directly behind the canines. Dog owners should now be looking visually for retained teeth. In puppies with a retained deciduous tooth, a permanent tooth is seen along-side the baby tooth it was meant to replace. The permanent canine teeth usually erupt in front of the deciduous canines.
All adult molars are now visible, Dog owners should now be visually assessing the correctness of their dog’s bit. Signs of an improper bit include teeth that contact the roof of the dog’s mouth.
Final stage in a dog’s tooth development. A dog now should have 42 permanent teeth and their bit should look and operate normally. If an owner expects something is not right it is important to have veterinarian dentistry correct the problems before they cause irreversible damage to a dog’s mouth. For example, the normal growth of the jaw bone may be hindered by an abnormal teeth alignment. Also, teeth that are mis-aligned can make it difficult for the puppy to eat. They can also accidentally cause the puppy to bite the inside of the mouth, causing pain and potential infections.

It is important to offer puppies various methods to relieve the pain from their teeth and gums during the teething period. A puppy should have access to different chew toys, this not only gives them something to chew it develops their ability to understand what is ok to chew and what they should not chew. Special chew toys that utilize ice offer the best relief from the swelling and inflammation puppies experience between 2 and 8 months of age.

Most of the permanent or adult teeth start as buds forming at the root tip of the deciduous teeth. Each deciduous tooth root will generally be absorbed by the adult tooth, though there are instances where this does not properly occur. At three months, the incisors begin to fall out to make room for the new adult teeth. At the age of four months, the adult molars and adult canines are beginning to come in. Between the ages of six and seven months, the adult molars will come in. Finally, by seven to eight months, the full set of adult teeth should have come in.

The summarized process permits owners a quick reference to monitor the process as puppy teeth fall out. Starting around three months of age, the developing permanent incisors should be erupting, and as they do, they should cause reabsorption of the roots of the deciduous incisors. Therefore, the puppy’s deciduous teeth become loose and fall out. This exfoliation of the deciduous teeth often goes unnoticed by the owners as the tiny crowns of the baby teeth are lost in toys or are swallowed. Next, the permanent canines start to erupt between four and five months of age, followed by the premolars and the molars. All the permanent teeth should have erupted by seven month of age in most dogs. Giant breeds sometimes develop more slowly. If everything went according to the plan, by seven or eight months of age, all deciduous teeth will be gone, all permanent teeth will have erupted into the correct position and there will be no swelling or inflammation of the gums. Unfortunately, things do not always go according to the plan.

Persistent Deciduous Teeth:
A common problem, particularly in small breeds, is persistence of deciduous teeth a failure of puppy teeth to fall out, especially the canines. The exact mechanisms for this are rather complex, but it is enough to know that it is usually an inherited problem in which the permanent tooth erupts beside the deciduous and so does not cause the deciduous root to resorb. Now we have two teeth occupying a space that was designed for just one tooth. This over-crowding can lead to serious and painful orthodontic problems such as lower canine teeth biting into the roof of the mouth.

When puppy teeth fall out it prevents another problem associated with the persistence of deciduous teeth. The permanent and deciduous teeth are often so close together that there is no gum tissue between them to keep out infection. Therefore, debris and bacteria have easy access to the tooth sockets and deep-seated periodontal disease rapidly develops. The rule to follow is that never should there be a deciduous tooth and its permanent replacement visible in the mouth at the same time. If the permanent has broken through the gum and the deciduous tooth is still in place, the deciduous tooth should be extracted immediately. This will then allow the permanent to erupt into its desired location without crowding and with a healthy collar of protective gum tissue. The use of natural antibacterial oral sprays and gels formulated for the chemistry in a dog’s mouth eliminate the harmful bacteria that cause plaque and tarter buildup. These products provide a long term oral care solution for dogs serving to avoid periodontal disease and expensive veterinarian dentistry.

Waiting until it is time for your puppy to be neutered is a bad idea. By then, the permanent tooth has erupted considerably and will likely be in the wrong place. Also, there may already be deep-seated periodontal disease by then. It is considered by many to be unacceptable to perform an extraction at the same time as a sterile surgical procedure. During extraction, bacteria in the mouth will have direct access to the blood stream. These bacteria can then travel to all parts of the body, including the other surgical site, where they may colonize the traumatized tissues and suture materials, leading to post-operative infection. It is safer for the animal and provides a better chance for normal development if retained deciduous teeth are extracted as soon as they are noticed.

Many puppies are given their final puppy vaccine at four months of age and then are not seen by their veterinarian again until neutering at six months of age. Therefore, it will be your job to check the mouth at least weekly to ensure that deciduous teeth are falling out properly, as the permanents erupt.

Fractured Deciduous Teeth:
Another common problem in puppies is fracture of deciduous teeth, especially the canines. As you will find out (if you haven’t already) puppies do a lot of chewing. Therefore, it is not surprising that these delicate teeth are prone to damage. When a deciduous tooth is broken, there is almost always exposure of the pulp of the tooth. Pulp is the soft tissue inside the tooth which contains many blood vessels and nerves. Once exposed to oral bacteria, the pulp becomes infected and inflamed, causing considerable pain to the pet. After a time (several days) the pulp starts to die and the pain subsides. Now the tooth is full of dead pulp and bacteria. The bacteria and their toxic waste products leak out through the root tip and cause infection and inflammation around the root tip. That in itself is bad enough, but remember that the permanent tooth is trying to develop right beside the tip of the root of that dead deciduous tooth. The result can be a permanently deformed permanent tooth.

Another factor to keep in mind is that a growing puppy is learning all the time. If there is an ongoing source of dental pain, the puppy may grow up being wary of anyone handling its mouth and head. This can lead to behavior problems later in life. As with retained deciduous teeth, the best thing to do is have a fractured deciduous tooth extracted as soon as it is noticed. Early treatment gives the best chance for the prevention of permanent dental and behavioral problems.

Interceptive Orthodontics:
Some puppies develop orthodontic problems early in life. The most obvious problems are when the lower jaw is either too long or too short. This can lead to deciduous teeth biting in to oral soft tissues, causing pain. Also, abnormal dental interlocks can prevent proper growth of the jaws so the short jaw is prevented from “catching up”. Early intervention through Interceptive Orthodontics is the treatment of choice. This usually involves extraction of some deciduous teeth to remove the source of oral trauma and to allow unhindered jaw development. Many severely affected puppies will also have problems when the permanent teeth erupt and will require further dental work in their first year of life.

Puppy Oral Care:

    • Reduce Bacteria Load in Dog’s Mouth (Reduce Inflammation of Gum Tissue)
    • Prevent Formation of Plaque & Tarter
    • Eliminate the Need for BRUSHING & VETERINARIAN DENTISTRY
