「molar」"My second and third molars had cavities, so the dentist pulled them out."
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.
