The detail information of Overshot jaw
Basic Information

Disease Description: A condition where the upper jaw is too long for the lower jaw.

Inherit Mode: -

Disease Symptom: Common problems that can arise from malocclusion: Mouth injuries, Periodontal disease, Soft-tissue defects from tooth contact in the floor of the mouth and the roof of the mouth (palate), Wear on the teeth, Fractures. If problems with the palate persist, a fistula may result and become infected. In cases of misaligned teeth (or malocclusion), the dog may have difficulty chewing, picking up food, and may be inclined to eat only larger pieces. They are also prone to tartar and plaque build-up. There are several types of diagnosable malocclusion: Overbite (sometimes called overshot, Class 2, overjet, or mandibular brachygnathism), Underbite (also called undershot, reverse scissor bite, prognathism, and Class 3), Level bite (sometimes called even bite), Open bite (front teeth don’t meet each other when mouth is closed), Anterior crossbite (canine and premolars occlude normally but one or more lower incisors are in front of the upper incisors), Posterior crossbite (one or more premolar teeth overlap the upper teeth), Wry mouth or bite (one side of jaw grows longer than the other), Base narrow canines (lower teeth protrude inward and can harm the upper palate). The tips of the premolars (the teeth right behind the canines) should touch the spaces between the upper premolars, which is called the scissor bite. However, it is normal for flat-faced breeds (brachycephalic) such as Boxers, Shih Tzus, and Lhasa Apsos not to have scissor bites. With an overbite, the upper jaw is longer than the lower one. When the mouth is closed, a gap between the upper and lower incisors occurs. Puppies born with an overbite will sometimes have the problem correct itself if the gap is not too large. However, a dog's bite will usually set at ten months old. At this time improvement will not happen on its own. Your pet's overbite may worsen as the permanent teeth come in because they are larger and can damage the soft parts of the mouth. Teeth extractions are sometimes necessary.

Disease Cause: The way the upper teeth align with the lower teeth is called occlusion. It is normal for most breeds to have a slight overlap of the upper front teeth. When the jaw is closed, the lower canine (fang) should fit in front of the upper canine. Most cases of malocclusion have a hereditary link.

Disease Diagnose: -

Treat Method: Most bite malocclusions do not require treatment. In some cases, extractions may be necessary. It’s a good idea to brush the teeth regularly to prevent abnormal build-up of tartar and plaque. Your veterinarian will sometimes recommend a dental specialist if you want to correct the teeth misalignment. In recent years, “braces” have been made for puppies to realign the teeth.
