What is an essential step in proper tooth brushing technique?

Using a 45-degree angle when brushing is crucial because this technique effectively targets the plaque accumulation at the gum line, which is often overlooked. By angling the brush in this manner, bristles can penetrate the sulcus—the small space between the tooth and gum—allowing for better cleaning than if the toothbrush were held straight against the tooth surface. This method not only helps in removing plaque but also aids in preventing periodontal disease and cavities by ensuring that the gums are adequately cleaned.

While the duration of brushing is important, simply brushing for at least one minute does not guarantee that all areas of the mouth are being cleaned effectively. Additionally, using hard bristles can be too abrasive and may damage both the tooth enamel and gum tissue, while focusing only on the outer surfaces neglects the inner surfaces and chewing surfaces of teeth, which are also prone to plaque buildup and decay. Hence, the 45-degree brushing technique is integral to a comprehensive oral hygiene regime.
