What is dental plaque?

Dental plaque, or dental biofilm as more recently named is a soft and sticky mass of bacteria that builds up on the teeth. The longer the plaque biofilm sits on the teeth, the more ‘nasty’ it becomes. Sugars in your diet become consumed by the bacteria in your plaque, which then makes the plaque become acidic. This acidic plaque will then start to demineralise the tooths enamel which can lead to tooth decay. Bacteria in plaque can also sit underneath the gums and cause gingivitis and gum disease.
 
Dental plaque starts to harden after 24 hours, turning into calculus. Calculus is difficult to remove at home with your toothbrush or floss because it is a harder substance than plaque. 
 
How to prevent plaque biofilm build-up:
 

• Brush your teeth twice per day for two minutes at a time with a soft bristled tooth brush or electric tooth brush. Pay particular attention to where your gums meet the teeth as this is where a lot of plaque can accumulate. Your dentist or hygienist will help you by showing you the correct technique for toothbrushing.
• Use a toothpaste that contains fluoride.
• Clean in between your teeth every day with interdental brushes or floss. Your dentist or hygienist can also help you by showing you the correct technique for this if you are unsure; and can help you find the right sized interdental brush for your needs.
• See your dentist or hygienist regularly for your 6 monthly professional cleaning.
• Eat a balanced diet and limit your intake of sugary foods and drinks.
