a) It is recommended to visit your dentist for regular check-ups. This will help detect dental problems such as caries or periodontitis early and take preventive measures for treatment before they worsen. Regular visits to the dentist are also important for plaque and tartar removal, which accumulate over time and can lead to problems with both teeth and gums. b) More frequent visits to the dentist may be recommended for individuals at higher risk of dental problems, such as those with periodontitis, diabetes, or immune disorders, as well as for smokers or those with poor oral hygiene.
