At-home oral hygiene. The most important prevention technique is brushing and flossing at least twice a day (or after every meal) to remove dental plaque, a film-like coating that forms on your teeth. If not removed, plaque can build up and produce dental tartar, a hardened, sticky substance with acid-producing bacteria that cause tooth decay and lead to gum disease.

Fluoride use. Fluoride strengthens teeth and prevents tooth decay. Fluoride treatments are provided in dental offices, and dentists recommend using fluoride toothpastes and mouth rinses at home. Public water fluoridation – ranked as one of the 20th century’s 10 great public health achievements – provides a major source of fluoride.

Diet. A balanced diet is a dental health essential. Foods with sugars and carbohydrates feed the bacteria that produce dental plaque, while calcium-poor diets increase your chances of developing gum (periodontal) disease and jaw deterioration.

Regular dental visits. Since most dental conditions are painless at first, if you don’t regularly visit your dentist, you may not be aware of dental problems until they cause significant damage. For best results, schedule regular dental check-ups every six months; more often if you’re at higher risk for oral diseases. Your dentist should also perform oral cancer screenings to check for signs of abnormal tissues. Especially for children, checking oral growth and development (including an assessment for caries development) should be part of dental evaluations.
