Brush your teeth before you go to bed! Otherwise, you will get a cavity.
Go brush your teeth before going to bed, or you will have a cavity!
If you don't want to have a cavity, you need to brush your teeth!
夜寝る前には必ず歯磨きしましょうね。虫歯になっちゃうぞー、は以下のように英訳できます。
１）Brush your teeth before you go to bed! Otherwise, you will get a cavity.
＝ベットに行く前に歯を磨きなさい。そうじゃないと虫歯になるよ！
Otherwise は、「そうでなければ」という前に述べた事の結果を表すもの。（２）の ORと同じ働きをしてます。
２）Go brush your teeth before going to bed, or you will have a cavity!
＝寝る前に歯を磨いていらっしゃい。そうじゃないと虫歯になるよ！
Goを追加することで、「歯をみがく」だけでなく「歯を磨きに行きなさい」の２つの行動を指しています。
（１）と（２）について：
動詞から始まるのは命令形だから、少しきつい言い方ではと思われがちですが、そんな事ありません。全て言い方次第です。子供に「～しなさいよ」は動詞でスタートしたものがほとんどですので、気にせず使ってください。
３）If you don't want to have a cavity, you need to brush your teeth!
＝もし虫歯になりたくないのなら歯を磨きなさい！
IF（もし）を使った表現もできます。
I hope it helps :)

英訳1：「歯を磨く」は、brush one's teeth です。
end up は、「（今すぐでなくても）ゆくゆくは、何か起こる」というニュアンスになります。with ~ を続けることで「〜が起こる」ことを表します。
or は「さもなければ」という接続詞です。
英訳2：例文1では、or you'll end up with cavities「さもなければ虫歯になっちゃうぞ」でしたが、同じ内容で、so「そうすれば」を使って、so you don't get cavities「そうすれば虫歯にならないよ」と言い換えることができます。
