As a general recommendation, children are advised to start visiting the dentist when their first teeth emerge (typically between 6 months and 1 year of age). Starting at this early age helps children develop a habit of dental visits and become aware of dental health. For adults, the usual age to begin general dental check-ups is around 18 years old. However, since everyone's oral health status varies, some may need to start at an earlier age. Particularly individuals at high risk of tooth decay or those with specific health conditions should begin general dental check-ups earlier. Additionally, special circumstances like pregnancy can affect dental health, making it important to consult a dentist during such times.
