Điều rất quan trọng để có một hàm răng khỏe mạnh. Răng tốt giúp chúng ta nhai thức ăn. Chúng cũng giúp người khác có cách nhìn tốt đẹp về mình. 1 chiếc răng sâu như thế nào? Sự phân rã bắt đầu trong một vết nứt nhỏ có trong lớp men răng. Điều này xảy ra sau khi vi trùng và những thực phẩm nhỏ đã được thu thập ở đó. Sau đó sâu răng từ từ lan rộng bên trong răng. Cuối cùng, chất độc đi vào máu và chúng ta có thể cảm thấy khá ốm.

Làm thế nào chúng ta có thể giữ cho răng khỏe mạnh? Đầu tiên, chúng ta nên đến nha sĩ hai lần một năm. Nha sĩ có thể lấp đầy những lỗ nhỏ trên răng của chúng ta trước khi chúng phá hủy răng. Anh ta có thể kiểm tra răng của chúng ta để kiểm tra xem chúng có đang phát triển đúng cách. Thật không may, nhiều người chờ đợi cho đến khi họ bị đau răng trước thì họ mới đi gặp nha sĩ.

Thứ hai, chúng ta nên đánh răng bằng bàn chải đánh răng và kem đánh răng ít nhất hai lần một ngày - một lần sau khi ăn sáng và một lần trước khi đi ngủ. Chúng ta cũng có thể sử dụng tăm gỗ để làm sạch các khe răng sau bữa ăn.

Thứ ba, chúng ta nên ăn thực phẩm tốt cho răng và cho cơ thể: sữa, phô mai, cá, bánh mì nâu, khoai tây, gạo đỏ, rau sống và trái cây tươi. Sô cô la, kẹo, bánh quy và bánh ngọt không được tốt, đặc biệt là khi ta ăn chúng giữa các bữa ăn. Chúng có hại vì chúng dính vào răng của chúng ta và gây sâu răng.
