Gingival recession, also known as gum recession and receding gums, is the exposure in the roots of the teeth caused by a loss of gum tissue and/or retraction of the gingival margin from the crown of the teeth. [1] Gum recession is a common problem in adults over the age of 40, but it may also occur starting in adolescence, or around the age of 10.
Ultrasonic toothbrush (Megasonex) An ultrasonic toothbrush is an electric toothbrush designed for daily home use that operates by generating ultrasound in order to aid in removing plaque and rendering plaque bacteria harmless. It typically operates on a frequency of 1.6 MHz, which translates to 96,000,000 pulses or 192,000,000 movements per minute.
Electric toothbrushes can also be classified according to the speed of their movements as standard power toothbrushes, sonic toothbrushes or ultrasonic toothbrushes. If the motion of the toothbrush is sufficiently rapid to produce a hum in the audible frequency of human range (20 Hz to 20,000 Hz), it can be classified as a sonic toothbrush. Any ...

A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
Gingival retraction or gingival recession is when there is lateral movement of the gingival margin away from the tooth surface. [1] [2] It is usually termed gingival retraction as an intentional procedure, and in such cases it is performed by mechanical, chemical, or electrical means in order to perform certain dental surgery procedures.
In about 60–65% of teeth, the cementum overlaps the enamel at the CEJ, while in about 30% of teeth, the cementum and enamel abut each other with no overlap. In only 5–10% of teeth, there is a space between the enamel and the cementum at which the underlying dentin is exposed.
Brushing and flossing can remove plaque from which calculus forms; however, once formed, calculus is too hard (firmly attached) to be removed with a toothbrush. Calculus buildup can be removed with ultrasonic tools or dental hand instruments (such as a periodontal scaler ).
