This poem expresses regret over neglecting one's oral hygiene and dental care when younger. The speaker wishes they had taken better care of their teeth by avoiding sticky and sugary foods that can cause cavities and damage. As a result of neglecting brushing and dental checkups, the speaker now requires multiple fillings and other dental work like root canals that cause much discomfort. The poem serves as a lesson about the importance of proper oral hygiene from a young age to avoid painful dental procedures later in life.
