A tooth with small cracks can be split open by a mere guava: dentists

A tooth with small cracks can be split open by a mere guava: dentists

2023-02-08

The internet was recently regaled by a cautionary tale of dentistry. A young woman was shocked to find a part of her tooth fall out while she was eating a guava. Most people would think the sweet fruit is not such a hazard. But dentists say that if your tooth already has small cracks in it, lots of foods could cause it to crack even more.

This X-ray shows a row of teeth. One of them has cracked to the root. It’s missing a big chunk. Astonishingly, it broke while the patient was eating a guava.

It’s absurd! There must be some other reason?

My dad’s tooth fell out while he was eating. The guava must have been too hard.

A dentist posted the story on Facebook. A young woman came to his clinic saying that she had just been nibbling on a guava. The dentist laughed – she was the third patient with a guava-induced cracked tooth that day. They would need ceramic crowns. The patient said she had no forewarning. But the dentist says in fact she had been warned there was a small crack in the tooth before, and should have dealt with it.

If there are already some small ruptures in the tooth, you just need to put force on that angle of the crack, and there is a real chance that it will break. You could break your tooth on a guava or even on bread.

A tooth can break on any harder object, if it already has decay or small cracks. The speed and angle of chewing are big factors too. Guavas have very hard seeds, say dentists. With a swift bite, even a healthy tooth could crack. Lots of foods need to be eaten with caution.

Apples have a slightly glossy surface, and when you bite into them with lateral friction, it could happen. Meat jerky and beef shanks and those kinds of tougher foods – because you don’t just bite them, you also have to grind them.

Dentists recommend that you eat slowly and mindfully if you have tooth decay or any cracks in your teeth. Don’t chomp down too forcefully on food, and give your jaw a break.

咬一口就牙裂! 牙醫認證「這水果」是牙齒終結者

你有吃過太硬的食物造成牙齒斷裂的經驗嗎?一名牙醫分享看診時遇到一名患者,說只是輕輕咬一下芭樂,牙齒就痛到受不了,一檢查發現原來是牙齒斷了。牙醫解釋,本身有蛀牙或牙齒缺陷的人都有可能遇到這樣的狀況,只要細嚼慢嚥就能避免。

X光攝影拍下,整齊排列的牙齒中,其中一顆從根部斷裂,缺了一角,沒想到這是吃芭樂造成的。

“很誇張,應該是有其他原因吧?”

“我爸的牙齒是吃到掉下來,就是芭樂太硬了。”

有牙醫在臉書上分享一名年輕女子來看牙,她說只是輕輕咬了一下芭樂,牙醫笑說,她是當天第三個因為吃芭樂牙裂,來作陶瓷嵌體的患者。女子感嘆牙裂沒有預兆,但牙醫表示,之前幫女子看診時,已經有建議牙齒上有裂痕,要認真處理。

“如果牙齒已經有了一些小小的缺損,只要剛好那個力量剛好誘發它斷裂角度的時候,事實上真的有機會,吃個芭樂甚至麵包,都有可能讓牙齒斷掉。”

牙齒本身就有蛀牙或裂痕,只要遇到稍微硬一點的食物就可能斷裂,另外咀嚼的速度和角度也都有關係。牙醫師分析,芭樂有很硬的籽,加上瞬間的咬合力量,就連健康牙齒也可能會裂掉,但其實有不少食物都得小心吃。

“蘋果本身它表面它是有點光滑的,咬的時候會有一個摩擦側向的力量的時候,其實也會發生。肉乾、牛腱這種韌性比較強的,因為它不但是要咬,它可能還要磨。”

醫師建議,有蛀牙或是牙齒有缺陷的人,吃東西一定要細嚼慢嚥,不要用力咬太硬的食物,就能避免牙齒突然斷裂。
