As parents become more aware of the disease, dental diseases of their pets are increasingly being taken seriously by parents. So it is essential for parents to understand basic dental knowledge and communicate with their pet’s attending physician in real time.

1. The usual number of teeth

The usual number of teeth in an adult canine, upper jaw (each volume has 3 incisors, 1 canine, 4 premolars, and 2 postmolars)

Usual adult dog teeth, lower jaw (3 incisors, 1 canine, 4 premolars, 3 molars) Therefore, an adult dog should generally have 20 teeth in the upper jaw, 22 teeth in the lower jaw, and a total of 42 teeth.

Cat Adult cats usually have upper jaw (incisors on each side) 3, 1 canine, 3 premolars, 1 posterior molar)

The normal lower jaw of an adult cat (3 incisors, 1 canine, 2 premolars, 1 rear molar)

So cats have 16 teeth in the upper jaw, 14 teeth in the lower jaw, and 30 teeth in the male. The teeth of a kitten are 3 incisors on the upper jaw, 1 canine, 3 premolars, 0 rear molars, and 3 incisors on the lower jaw. , 1 canine, 2 premolars, a total of 26 teeth: 3 incisors, 1 canine, 3 premolars, 0 rear molars on the upper jaw, 3 incisors, 1 canine, and premolars on the lower jaw. 3, 0 rear molars, 28 in total) The number of teeth in young animals is different from that in adult animals.

Two. The age of each tooth

Canine teeth last forever, and teeth begin to change at three months. Cat teeth last forever, and teeth start to change at three months. The animal can be determined based on the time of tooth replacement.

3. Teeth anatomy

Dog, basic bite form, dog. The canines of the lower jaw are behind the canines of the upper palate.

Cat basics Original bite pattern: front side (improved Triadan system, divides the oral cavity into 1-4 quadrants, looks at the animal in a clockwise direction, starting from the upper collar bone on the right side and ending at the lower collar bone on the right side. Using this system, the right The incisors of the lateral collar bones are numbered 101, 102 and 103. The canine teeth end in 4 (104, 204, 304 and 404), and the first molars end in 9 (109, 209, 309, 409). The same method numbers, each quadrant is headed by 5, 6, 7, 8)

Canine dental record form, examples, are there any unique forms? The dental record form is filled out during the dental examination and carefully records the health of each tooth.

6. Dental examination

Periodontal probe is used to explore periodontal pockets. The tip of the probe is inserted into the heel groove and slowly wraps around the tooth to measure the depth of the heel groove. Most oral examination records can record the results of periodontal depth measurements at 4-6 locations on each tooth. Recorded are the vertical target, the center of the labial/buccal side and the center target of the lingual/tiffany side. When measuring the depth of the heel groove, it is normal to have less than 3mm for dogs and less than 1mm for cats. Once the depth exceeds the normal value, it is periodontal disease. False heel bags are caused by tooth heel hyperplasia (commonly seen in Boxer dogs). Heel atrophy can also be measured with a periodontal probe. The handle of the probe can be used to check the looseness of the teeth. Gently apply pressure to determine the looseness of the teeth.

The heelitis index is scored from 0 to 3, with 0 being a strong heel; 1 being slightly Inflammation, characterized by swelling of the gums and red edges; 2. Moderate inflammation, characterized by bleeding when using a probe to probe the heel of the tooth; 3. Severe heelitis, with spontaneous bleeding after slight vibration

The score of calculus index, mild calculitis is when there is a little calculus on the edge of the heel, moderate calculitis is when there is a small amount of calculus on the edge of the heel. There are stones on the teeth and teeth. Severe gum disease is a common condition in which the surface of the teeth is covered with stones. Although the stone itself does not necessarily cause periodontitis, its rough surface can aggravate periodontal disease.

If the animal suffers from severe periodontal disease and the doctor suspects that there is extensive bone resorption after probing the periodontal periodontitis, he should take X-rays of the severely affected areas to determine Whether the underlying bones are intact and whether pathological fractures have occurred. In addition, X-rays should be taken before periodontal scraping and polishing.
