Baby teeth are important Acidic fruits will whiten your smile.

乳牙很重要 酸性水果能美白你的笑容。

Yeah fillings last forever Yeah, they're kind of like relationships.

是啊，補牙是永恆的 是啊，它們就像人與人之間的關係

I'm dr. John you I'm a pediatric dentist in New York City and New Jersey It was between this and kpop.

我是約翰醫生，是紐約市和新澤西州的兒科牙醫。

I'm an orthodontist and Australian teeth for a living and today We will be debunking myths about teeth Cavities are irreversible.

我是一名牙齒矯正醫生，在澳洲以牙齒矯正為生。今天，我們將揭穿關於牙齒的神話齲齒是不可逆轉的。

That doesn't mean though that we've been fooling you guys Your entire life some cavities are reversible.

但這並不意味著我們一直在愚弄你們 你的一生中，有些蛀牙是可逆的。

Some are irreversible Depends on the depth of the cavity if you look at the three layers of your teeth the outer layer Enamel has the capability to remineralize if the cavity is within the enamel Technically, it's reversible if the cavity penetrates to the second layer Denton which is made up of a bajillion microtubules.

有些是不可逆的 取決於蛀牙的深度 如果你看一下牙齒的三層結構 外層琺琅質有再礦化的能力 如果蛀牙在琺琅質內 技術上講，如果蛀牙穿透到第二層牙本質，它是可逆的 牙本質由數十億微管組成。

The bacteria can now shoot through the tubes Into the pulp which is the center of your tooth where your blood supply and your nerves are housed Yeah, if it goes into the second layer, I may recommend to the patient.

如果細菌進入第二層，我可能會向患者推薦牙髓。

Hey, this is most likely going to get bigger We don't know how fast But we don't want to wait too long when we have to drill into the tooth and do a filling most times It is irreversible.

嘿，這很可能會越來越大，我們不知道速度有多快，但我們不想等太久，因為大多數情況下，我們必須鑽孔補牙，這是不可逆轉的。

And if you have a small cavity limited to the enamel, what can you do at home?

如果您的小蛀牙僅限於琺琅質，您在家裡能做些什麼呢？

you want to limit your acid sugar intake your enamel is the hardest substance in your body over time just like the Brick wall of a building may wear away with weather and storm Patchwork is needed and what patches up the lost minerals in the enamel is the fluoride in your toothpaste Acidic fruits will whiten your smile.

隨著時間的推移，你的琺琅質是人體中最堅硬的物質，就像建築物的磚牆可能會隨著風雨而磨損一樣，需要進行修補，而牙膏中的氟化物就是修補琺琅質中流失的礦物質。

Oh, please don't do this Don't do with acid that you have in your refrigerator the acid will erode your teeth You may even develop cavities erosion is real put a picture of erosion up here in some ways It does get whiter what happens is like the chromogens which are like the pigmented molecules We talked about with the whitening the acidic fruits.

哦，請不要這樣做 不要用冰箱裡的酸來做，酸會腐蝕你的牙齒，你甚至可能長出蛀牙 酸蝕是真實存在的，在這裡放一張酸蝕的圖片，從某種程度上說，酸蝕確實會讓牙齒變白，發生的事情就像色素分子一樣，我們在美白酸性水果時說過。

They disperse that as well It makes the teeth a little bit whiter But the worst part is you're actually weakening the teeth more than you are actually whitening the teeth.

但最糟糕的是，你實際上是在削弱牙齒，而不是真正美白牙齒。

是以，從長遠來看，這並不是一件好事。

If you want to whiten your smile What do you recommend in office whitening?

如果您想美白您的笑容，您有什麼建議？

Maybe once or twice a year and then to maintain it like at home at home whitening kits The hydrogen peroxide the carboxyl whitening product is a controlled short duration treatment not fruit.

過氧化氫和羧基美白產品是一種可控的短效治療，而不是水果。

Stay away from your orange Braces are just for crooked teeth.

遠離你的橙子 牙套只是用來矯正歪牙的。

Most of my patients I would say it's for aesthetics But at the same time there's a lot more reasons than just crooked teeth that you get braces or aligners There's the functional aspects as well Obviously under bites over bites cross bites deep bites open bites also like grinders traumatic occlusion Any sort of spacing issues?

我的大多數病人都會說這是為了美觀，但與此同時，除了牙齒歪斜之外，還有很多原因會讓你戴上牙套或矯正器，還有功能方面的問題，比如明顯的咬合不足、咬合過度、交叉咬合、深咬合、開放咬合以及磨牙等創傷性咬合問題。

we usually do aligners in those patients because we have this extra protective layer over their teeth while Straightening and fixing their bites at the same time.

我們通常會為這些患者佩戴矯正器，因為在矯正牙齒的同時，我們還能為他們的牙齒提供額外的保護層，修復他們的咬合。

So many parents might say my kids nine years old.

很多家長可能會說，我的孩子才九歲。

I see need aesthetic teeth He doesn't even care.

我看到需要美觀的牙齒，他卻根本不在乎。

Yeah, the patient has severe crowding if nothing's done Impaction will occur.

是的，病人有嚴重的牙齒擁擠，如果不採取任何措施，就會發生牙嵌塞。

That's when the teeth get jammed up in the traffic jam and that makes the Orthodontics or movement harder when they're teenagers.

這時候，牙齒就會被堵在交通堵塞的地方，從而使青少年時期的牙齒矯正或移動變得更加困難。

They're in braces for a longer time So before the problem gets too big we try to fix functional components and then the aesthetics can always follow.

他們戴牙套的時間較長，所以在問題變得太大之前，我們會盡量修復功能性部件，然後再進行美學修復。

Yeah Knocked out tooth is gone for good No Time is of the essence here is important to know that a knocked out tooth is not a dead tooth This is considered an emergency because if the tooth can be Reimplanted by the dentist within half hour one hour max.

是的，牙齒磕掉了就永遠沒有了，時間就是生命，重要的是要知道，磕掉的牙齒並不是死牙，這被認為是一種緊急情況，因為如果牙醫能在半小時內重新植入牙齒，最多不超過一小時。

Yeah, it does have a increased odds of survival Reimplantation if it's possible is Step one.

是的，如果可能的話，再植手術是第一步。

It sounds crazy But put it back in the tooth because that's where it's home is now if that's not possible put it in a glass of milk Also, not a joke.

聽起來很瘋狂，但還是把它放回牙齒裡吧，因為那才是它現在的家，如果不行，就把它放進一杯牛奶裡吧 另外，不是開玩笑。

So what type of milk whole milk is the best choice?

那麼，哪種全脂牛奶是最佳選擇呢？

the milk has a similar pH to these cells on the root of the tooth and If you can keep the cells alive for longer, then tooth has a better chance of survival there is a common misconception that you could put the tooth in water Don't do that.

牛奶的酸鹼度與牙根細胞的酸鹼度相似，如果能讓細胞存活更長時間，那麼牙齒存活的機會就更大。

In fact, your saliva is better putting in a bag of saliva water will make the cells on the root pop Diet sodas won't give you cavities Myth myth guys myth.

事實上，你的唾液最好放一袋唾液水，會讓根部的細胞爆裂 飲食蘇打水不會讓你長蛀牙 神話的傢伙們的神話。

I do like the effort Why does it cause cavities not necessarily because they don't have any sugar at all?

我很喜歡這種努力 為什麼蛀牙不一定是因為沒有糖？

But it's because of the pH levels being low and it's acidic There are certain drinks that are more harmful You want to look at the pH of them the sugar content sports drinks soda?

但這是因為 pH 值低，是酸性的，有些飲料的危害更大。

Wine these healthy things like orange juice apple juice.

葡萄酒這些健康的東西，比如橙汁蘋果汁。

They may be good for vitamins Dental standpoint, they are attacking your teeth Sorry to rain on your parade.

從牙科的角度來看，它們可能對維生素有好處，但它們是在攻擊你的牙齒，對不起，是在給你的遊行造勢。

You look at the pH of milk It's a lot less acidic and it has more protective factors water is best water Enjoy moderation Fillings last forever.

看看牛奶的酸鹼度，它的酸性要低得多，而且有更多的保護因子，水是最好的水，適量飲用吧。

They're kind of like relationships your relationship with your wife.

它們有點像你和妻子之間的關係。

That's gonna be forever but in certain situations They may not you actually see that a lot of the times where you need to redo a filling It's from an existing filling.

但在某些情況下，他們可能不會這樣做。實際上，很多時候，你需要重新補牙時，都是在已有補牙的基礎上進行的。

It wasn't sealed all the way It could be that there was a little bit of cavities underneath it and then it got a little bit worse and then you got To do the filling again, even after you get a filling if you're still not flushing You're still not brushing.

可能是下面有一點蛀牙，然後情況變得更糟了，你就得重新補牙，即使補了牙，如果你還是不刷牙，你還是不刷牙。

You can easily just get another cavity where that existing filling was So the maintenance on the patient side is also very important.

是以，患者方面的維護也非常重要。

It is a preventive service along with the examination.

這是一項與檢查同時進行的預防性服務。

It's not the dental cleaning itself It's like getting an annual checkup for some patients Even a six-month cleaning is not enough.

這不是洗牙本身的問題，對有些患者來說，這就像每年做一次體檢一樣，即使是半年一次的洗牙也是不夠的。

Some patients come back every three months So it depends if you do have calculus or very hard plaque we use in the office Scalers, which are very sharp blades to scrape off things We use a cabotron which is an ultrasonic machine that sprays out water and bursts these things into pieces This is very satisfying Our job as dentists is to maintain your oral health and there are certain things that you can't do at home that we can do So the cleaning is just one way for us to regularly check up on you and to make sure everything's going okay Retainers aren't for life.

有些病人每三個月來一次，所以這取決於你是否有牙結石或很硬的牙菌斑、我們使用超音波機（cabotron），它可以噴出水來，將這些東西炸成碎片，這非常令人滿意。作為牙醫，我們的工作就是維護您的口腔健康，有些事情您在家裡做不了，但我們可以做。

Ah, this this one hits home I've worn a retainer for about 25 years now in my life If you want to keep your teeth exactly where they are It's hard to say that hey, you don't need a retainer So the purpose of a retainer after you get braces after you get aligners It's to hold your teeth in that position so that your smile stays the way that it is But then secondarily we see a lot more grinders in the office and with those grinders It actually adds as an extra layer of protection so that if they grind they're gonna grind away the plastic before they grind away their own Teeth over time the relapse potential is less and less but it's never zero You want to keep relapse incidents lowest then you should wear for as long as possible So you could be on your deathbed with your retainers You should floss before brushing.

如果你想讓你的牙齒保持原位，很難說你不需要保持器、所以在你戴上牙套和矯治器之後 戴保持器的目的就是把牙齒固定在原位 這樣你的笑容就會保持原樣隨著時間的推移，復發的可能性會越來越小，但永遠不會是零 你想把複發率降到最低，就應該戴得越久越好 所以你可能在臨死前還戴著保持器 你應該在刷牙前使用牙線

I floss first I do too Technically, it doesn't matter.

我也是先用牙線清潔，從技術上講，這並不重要。

I'm not gonna make you floss before But logically it makes sense to you're debriding between the teeth.

我不會讓你在用牙線之前用牙線，但從邏輯上講，你在牙齒之間除屑是有道理的。

You're brushing after then you're rinsing Makes sense.

That's why there's no general consensus What happens if you don't floss and you don't clean that up to 40% of surfaces very commonly I have to treat what's called interproximal decay That's decay in between teeth that are not visible to the eyes and that if the calculus builds up there over time you get that little bit of bone loss and If you don't clean it, then that's what leads to like the gum disease in general I don't think it matters if you floss before you brush.

這就是為什麼沒有達成普遍共識的原因，如果你不使用牙線，不清潔牙面，會發生什麼情況呢？我通常要治療40%的牙面齲齒，這就是所謂的近端間齲齒。

The most important thing is that you actually do floss Baby teeth are important Parents often ask Why do we need to treat this cavity?

最重要的是，你真的使用了牙線 寶寶的牙齒很重要 父母經常會問，為什麼要治療這個蛀牙？

He's gonna get a new one in a couple years, right?

Baby teeth are like the space holders if you lose them a little bit too early your teeth won't know where to go and then The teeth can get confused a little bit.

乳牙就像空間的保持者，如果你過早地失去乳牙，你的牙齒就會不知道該去哪裡，然後牙齒就會有點混亂。

Kids can also have psychological effects from it.

孩子們也會是以受到心理影響。

Losing two front teeth Very early three-year-old might not care but a four or five-year-old might.

掉了兩顆門牙 三歲多的孩子可能不會在意，但四五歲的孩子可能會在意。

In these instances It's important to prioritize a child's development, speech, psychological well-being, and of course the orthodontic preservation Everyone has wisdom teeth Myth Myth.

在這種情況下，重要的是要優先考慮孩子的發育、語言表達、心理健康，當然還有牙齒矯正。

The wisdom teeth are the most commonly Congenitally missing teeth.

智齒是最常見的先天性缺失牙齒。

That means that some people aren't born with them.

這就意味著，有些人並不是與生俱來的。

I had three so I'm less wise than Dr. Lin They're the third molars.

我生了三顆，所以我沒有林醫生那麼聰明，那是第三顆臼齒。

They're the ones all the way in the back.

Typically you see them if they erupt Between 17 and 21 and very commonly they are removed because they become impacted It's a good idea to remove them before they become a problem.

通常情況下，如果它們在 17 到 21 歲之間萌發，就會被移除。

Like maybe in your like late teens early 20s College kids.

比如，你可能是十幾歲二十出頭的大學生。

Because the bone isn't as dense as if you were in your 30s or so So no, not everybody has wisdom teeth and when it comes to whether or not you need to get your wisdom teeth out That's also a myth.

因為骨骼的密度不如你 30 多歲的時候那麼高，所以並不是每個人都有智齒，至於是否需要拔掉智齒，這也是一個神話。

Not everybody needs to get them out Hydrogen peroxide and baking soda are good toothpaste replacements Myth.

不是每個人都需要取出牙膏 雙氧水和小蘇打是很好的牙膏替代品。

Yeah, it's missing a key ingredient, which is Fluoride Let's say that you're lost in the woods.

是的，它缺少了一種關鍵成分，那就是氟化物 假設你在森林裡迷路了

I feel like it's better than nothing It's more important to brush it off.

The hydrogen peroxide and baking soda are parts of your toothpaste, but it's not the whole thing So you're missing the one The muscle part.

過氧化氫和小蘇打是牙膏的組成部分，但不是全部，所以你缺少了肌肉部分。

So do yourself a favor and grab some fluoride toothpaste You're too old to get braces.

所以，幫你自己一個忙，買點含氟牙膏吧 你已經過了戴牙套的年齡了。

It's not even just like a functional thing I think self-esteem plays a lot for adults and kids So there's no such thing as adult braces.

我認為自尊對成人和孩子都很重要，所以沒有成人牙套這種東西。

Braces that we use for teenagers and adults are the same But one thing I will say is we do do a lot of aligners for my adult patients So these are aligners so basically something like this you get little bumps on your teeth and then the tray Goes over the top of it and these this is basically the clear alternative to braces.

我們為青少年和成年人使用的牙套是一樣的，但有一點我要說的是，我們為成年患者做了很多矯正器，這些就是矯正器，基本上就是這樣的東西，你的牙齒上會有一些小凸起，然後托盤會覆蓋在上面，這些基本上就是牙套的透明替代品。

The issue is the compliance 90% of the time.

90% 的情況下，問題在於遵守規定。
