上の1番奥と奥から2番目の歯が虫歯なので抜かれましたって英語でなんて言うの？

奥歯は、「molar」もしくは「Back teeth」と言います。 「molar」"My second and third molars had cavities, so the dentist pulled them out." 詳細な説明は以下です。 The 3 large teeth at the back of the mouth are called "molar's" in English. The medium sized teeth in front of those are known as "premolar's". The sharp teeth are called "canine's" and the front teeth are known as "incisor's". I hope this will help you. お役に立てば嬉しいです
