A VISIT TO THE DENTAL CLINIC

Please help me correct them, thanks.

(a) John was a lazy boy. He disliked brushing his teeth after meals. Last night, John went back from the wedding dinner. He could not sleep well. He tossed about in bed because felt a sharp pain in his gum / teeth. He cried out for help. His mother gave him some painkiller to stop his pain.

(b) The next morning, his mother took him to the dentist / dental clinic. John was very scared and looked pale in his face (when he saw a dentist ). A / The dentist checked his gum / teeth and found a cavity in his teeth.

(c) The dentist checked and treated his decayed tooth. After a short while, he was relieved and felt no more pain / painful. The dentist adviced him to eat more fruit and vegetables to keep his healthy teeth. He promised the dentist and went home happily.
