Brushing teeth morning and night is a common habit, yet some skip evening brushing. Do you know the health risks of skipping nighttime brushing? Here are the dangers of not brushing at night:
1. Skipping brushing may increase heart disease risk? A UK study found that never or rarely brushing teeth raises heart disease risk by 70% compared to twice-daily brushing.
2. Skipping nighttime brushing poses significant health risks. Failing to brush before bed greatly increases susceptibility to colds and pneumonia, while also accelerating tooth decay, gum bleeding, periodontal disease, and even tooth loss.
3. Brushing is an effective measure for maintaining oral health, and developing the habit of brushing after meals benefits overall well-being. Regarding evening brushing—specifically after dinner—and whether brushing is necessary upon waking in the morning, I believe it's best to brush after meals. Rinsing your mouth with water after waking is sufficient to eliminate bad breath and enhance appetite.
Proper Brushing Technique
Effective brushing: Use a soft-bristled health toothbrush. Position the bristles at the gumline, angled at 45 degrees toward the roots, and gently vibrate in place. Then brush vertically along the gumline.Alternatively, use circular motions on tooth surfaces; brush all areas in a systematic order; brush twice daily; maintain a 3-minute brushing duration per session.
Some individuals brush horizontally, akin to sawing. This technique is detrimental, as prolonged use can "saw" deep grooves at the tooth roots—medically termed "fissure erosion."Individuals with this condition may experience mild tooth sensitivity to hot, cold, acidic, or sweet foods. In severe cases, it can lead to pulpitis, causing excruciating tooth pain that makes sitting or standing unbearable.
Adhering to proper brushing techniques removes plaque while massaging the gums. Healthy individuals typically brush once or twice daily, but those with gum or periodontal disease should emphasize morning and evening brushing, adding an extra session after lunch. Each session should last three minutes. The correct methods are the short horizontal brushing technique and the vertical rotating technique.
Short-Horizontal Technique (also known as the Horizontal Vibration Method): The common horizontal brushing motion resembles a long sawing action. When combined with a hard-bristled toothbrush, this method can damage the periodontium (causing bristle damage to the gum line, gum recession, and wedge-shaped defects at the root-cervical junction).The short-horizontal technique uses short, vibrating horizontal strokes to most effectively remove plaque, hence its alternative name: intra-sulcular brushing. Position the bristle tips at a 45° angle to the tooth-gum junction with light pressure, allowing part of the bristles to enter the gingival sulcus while part remains outside. Then perform 6–8 back-and-forth vibrations, with bristle movement limited to 1mm during each vibration.When cleaning the lingual surfaces of upper and lower anterior teeth, if the dental arch is narrow, hold the brush vertically and use short horizontal vibrating strokes. Simultaneously, pull the brush to clean the occlusal surfaces of posterior teeth, removing plaque from pits and fissures.
Vertical Rotation Technique: Effectively removes plaque and soft deposits while stimulating gingival keratinization to maintain normal gingival contours. Suitable for a wide range of brush surfaces; both firm and medium-firm bristles are acceptable. However, elderly individuals, children, or those recovering from periodontal surgery should use medium-firm or soft bristles.When brushing the labial/buccal surfaces and lingual/palatal surfaces of posterior teeth, position the bristles parallel to the tooth's long axis, pressing them against the tooth surface with the bristles directed toward the gingival margin. Apply pressure while rotating the brush to form a 45° angle between the bristles and the tooth's long axis. Rotate the brush: for upper teeth, brush downward along the interdental space; for lower teeth, brush upward.Perform movements slowly with slight vibration, repeating 5–6 times per area. For the lingual surfaces of anterior teeth, use the same rotational motion. Those with narrow dental arches may hold the brush vertically, pressing part of the bristles against the gums, and brush along the interdental space toward the crown. Simultaneously brush the occlusal surfaces of posterior teeth.
Toothpaste contains abrasives and cleaning agents that help prevent cavities, reduce inflammation, stop bleeding, neutralize acids, relieve pain, inhibit tartar buildup, and reduce bad breath. Using toothpaste while brushing enhances the cleaning effect.
That concludes our discussion on the dangers of skipping nighttime brushing. We hope you now have a clearer understanding. Finally, we sincerely wish you good health and happiness.
