Oral hygiene
Regular oral hygiene prevents dental disease and bad breath.
Oral hygiene is the practice of keeping the oral cavity clean and free of disease and other problems, such as bad breath, through regular brushing of the teeth and adopting good hygiene habits. It is important that oral hygiene be carried out on a regular basis to enable prevention of dental disease and bad breath, which include tooth decay (cavities, dental caries) and gum diseases like gingivitis and periodontitis.

- Prevention of tooth decay and gum disease through regular brushing, interdental cleaning, and professional care
- Common practices
- Brushing at least twice a day with fluoridated toothpaste; interdental cleaning with floss, tape, or brushes
- Major diseases prevented
- Tooth decay, gingivitis, periodontitis
Lore & Background
General guidelines for adults suggest brushing at least twice a day with a fluoridated toothpaste: before going to sleep at night and after breakfast in the morning. Cleaning between the teeth, called interdental cleaning, is as important as tooth brushing because a toothbrush cannot reach between the teeth and removes only about 50% of plaque from tooth surfaces. Tools for interdental cleaning include floss, tape, and interdental brushes, with choice left to the individual.
Reader's Guide
Oral hygiene is significant because tooth decay is the most common global disease, and severe gum disease causes at least one-third of adult tooth loss. The role of the oral microbiome in dental health has been increasingly recognized; modern oral microbiota are significantly less diverse than historic populations, and caries have become a major endemic disease affecting 60–90% of schoolchildren in industrialized countries. Professional cleaning includes tooth scaling, tooth polishing, and debridement, often followed by fluoride treatment, though evidence for benefits of supragingival scaling and polishing is limited. Dental sealants applied by dentists cover fissures in back teeth to prevent decay. Powered toothbrushes reduce dental plaque and gingivitis more than manual brushing in both short and long term, though further evidence is needed to determine clinical importance. The Australian Healthcare and Hospital Association's evidence brief suggests dental check-ups every three years for adults and every two years for children, contradicting more frequent advice often given by dental professionals.
Did You Know?
- Over 80% of cavities occur inside fissures in teeth where brushing cannot reach trapped food.
- Dental calculus is composed of calcium phosphate minerals with live microorganisms and must be removed by a dental professional.
- The average brushing time for individuals is between 30 seconds and just over 60 seconds, though two minutes is recommended.
- Archaeological evidence shows marked shifts in the oral microbiome towards a disease-associated microbiome during the Industrial Revolution.
Frequently Asked Questions
Who is Oral hygiene?
Oral hygiene is the ongoing practice of keeping the mouth clean and healthy through consistent daily care. It sits within the fields of dental health and preventive medicine, focused on protecting the oral cavity from disease and issues like bad breath.
What are Oral hygiene's powers/role?
Its core function is stopping tooth decay, gingivitis, and periodontitis before they establish themselves in the mouth. It achieves this through regular brushing, interdental cleaning, and periodic professional dental visits.
Why is Oral hygiene important?
Neglecting it allows plaque to accumulate, which triggers cavities, inflamed gums, and eventually advanced conditions like periodontitis. It also prevents chronic bad breath, making it essential for both dental and general well-being.
What are Oral hygiene's signature tools?
Its most recognized instruments are fluoridated toothpaste applied at least twice a day, paired with floss, interdental tape, or small brushes for the spaces between teeth. Professional cleanings and check-ups complete the toolkit.
