FIVE STEPS TO DENTAL HEALTH
Dental health is an important part of total well-being. Nearly all dental diseases - tooth decay and periodontal (gum) disease - are preventable. All you have to do is to follow these five steps to dental health:
1. Brush and floss your teeth thoroughly at least once a day. Toothbrushing is well-known to remove plaque from the outer, inner and biting surface of the teeth. Tooth decay and periodontal disease often start in those areas where a toothbrush cannot reach. Only flossing removes plaque from between the teeth and under the gumline.
2. Brush your teeth after meals when you can. Remember to brush gently with short strokes and enough pressure, changing the tooth brush position frequently.
