what do you learn from the poem " Oh, I wish i'd looked after me teeth"?

The lesson that we learn from the poem, "Oh! I wish I'd looked after me teeth" is that we should take care of our teeth. If we fail to do so, we have to undergo a lot of pain. This is what happened with the narrator of the poem. She went on eating various soft and hard sweets. These were: lollies, toffees, sweet sticky food, gobstoppers, all sorts ofliquorice, sherbet dabs, 'hard peanut brittle.'.She also brushed her teeth up and down regularly, but casually at night. She hoped that she was taking due care of her teeth. But, she never gave up eating candies and all kinds of sweets. The result was out soon. She had paved the way for getting 'cavities, caps and decay'. And, she had had them. Then it was inevitable that she would go to the dentist. she underwent the pain of injections and drilling. She felt very sad after all that. She repeatedly said that it would have been better if she had stopped eating all kinds of sweets when her teeth had not been damaged.
