Most people should visit the dentist every six months (twice a year) for routine checkups and professional cleanings. This helps maintain oral health, prevent cavities and gum disease, and catch any problems early. However, the exact frequency can vary depending on one's oral health, lifestyle, and risk factors. More frequent visits, such as every 3 to 4 months, are recommended for those with gum disease, a history of dental problems, or other risk factors like diabetes or smoking. People with excellent oral hygiene and no issues might only need to visit once a year, but this should be confirmed with a dentist who can personalize the advice based on individual needs. The timing can range from as short as 3 months to as long as 1-2 years depending on oral health status.
