Vitamin D also plays a major role in calcium absorption and bone health because it helps to maintain calcium homeostasis and bone metabolism. [7] Deficiencies negatively impact parts of the teeth including the gingivae, periodontal ligaments and the alveolar bone, leading to degeneration of the teeth and jaw. [2] [9]
While resorption of bone is a normal physiological response to stimuli throughout the body, root resorption in permanent dentition and sometimes in the primary dentition is pathological. The root is protected internally (endodontium) by pre-dentin and externally on the root surface by cementum and the periodontal ligament.
They are often the largest teeth in a mammal's mouth. Individuals of most species that develop them normally have four, two in the upper jaw and two in the lower, separated within each jaw by incisors; humans and dogs are examples. In most species, canines are the anterior-most teeth in the maxillary bone.
Occlusal trauma; Secondary occlusal trauma on X-ray film displays two lone-standing mandibular teeth, the lower left first premolar and canine. As the remnants of a once full complement of 16 lower teeth, these two teeth have been alone in opposing the forces associated with mastication for some time, as can be evidenced by the widened PDL surrounding the premolar.
Dog treats are often given to pets as a reward or just to let them chew on a bone, which works their jaw muscles and helps keep their teeth clean. [67] Although dog treats carry high benefits for dogs' teeth, they can also be a source of problems like obesity when given excessively, especially human table scraps.
In addition to tooth crown build-up, ankylosed teeth repositioning is another conservative method. In surgical luxation, after the bridge of ankylosis is broken mechanically, the tooth is positioned slightly away from its original site and allowed to erupt with a temporary insertion of a splint or an orthodontic appliance.

Teeth of a rottweiler. Dogs are less likely than humans to have tooth decay due to the high pH of dog saliva, which prevents an acidic environment from forming and the subsequent demineralization of enamel which would occur. [56] If tooth decay does occur (usually from trauma), dogs can receive dental fillings just as humans do.
Dental alveoli (singular alveolus) are sockets in the jaws in which the roots of teeth are held in the alveolar process with the periodontal ligament. The lay term for dental alveoli is tooth sockets. A joint that connects the roots of the teeth and the alveolus is called a gomphosis (plural gomphoses). Alveolar bone is the bone that surrounds ...
