BB牙斷咗,留喺口腔一日都嫌多? By Dr. Jonathan
作為牙科獸醫,最難說服客人做的就是把一隻幾個月大的動物麻醉,拔去用了一、兩個月的BB犬齒。今天的例子,或者能更容易令主人明白,為什麼乳齒斷裂是急症,需要立刻拔掉。
今天我們為一隻4個多月大的哥基拔除斷了的右上顎犬齒。牙齒斷了約一個月,牙髓死去變色,在我們3天前的例行檢查中發現。 今日再打開口腔檢查,牙肉已長出牙瘡。X光見到犬齒牙根有含膿,細菌感染範圍再大一點,便會影響到底層在長出的成犬犬齒。而斷裂的牙齒表面在X光有被吸收的情況,表面變得不平滑。如果沒有拔去牙齒,沖走含膿,成犬犬齒會受到破壞,有機會不能順利長出。
牙根含膿在人類是非常痛苦的。對寵物來說,並不容易表達給主人知道,到影響咀嚼、食慾時,已經十分嚴重。
所以,斷牙,是急症,沒什麼好觀察,不要等到問題發生才處理。為一隻只有幾個月壽命的乳齒,而放棄用十幾年的成犬犬齒,是很不智的。
Leaving a broken baby tooth in the mouth is a disaster waiting to happen Dr. Jonathan
As a veterinarian dealing with lots of dental cases, the most difficult thing to persuade owners is to let us anaesthetise a pet that is several months old so we can remove a broken canine tooth. This advice may seem very aggressive to the pets as these teeth only erupted 1 or 2 months ago. Today’s example will make it easier for owners to understand why a broken baby tooth is an emergency and need to be removed immediately.
Today we removed the broken upper right baby canine of a 4-month-old Corgi. The tooth has been broken for about a month and the pulp has become discoloured. We discovered it during a visual examination 3 days ago. I examined the mouth again today and found a swelling on the gums. Dental X-ray showed an abscess in the root of the baby canine. The abscess can potentially destroyed the erupting adult canine. There is also resorption on the fractured tooth surface, which makes it look rough. If the broken baby tooth is left behind, the adult canine teeth will be damaged and may not erupt.
Tooth root abscess is very painful for humans. For pets, it is not easy for owners to see clear clinical signs. However, by the time it affects chewing and appetite, it is already very serious.
Therefore, a broken tooth is an emergency and therefore nothing is worth observing. Don‘t wait until the problem occurs. It is unwise to give up the adult canine tooth that will last decades for a deciduous tooth that will only be used for a few months.
