what’s the reason for yellow teeth?
1. Bad habits in life: for example, regular smoking and drinking will lead to yellowing of teeth, which should be paid attention to in life.
2. Hygiene habits: some people neglect oral hygiene and often don’t brush their teeth at night, resulting in a layer of food residue on the surface of their teeth, such as dental calculus, smoke stains, tea stains, etc. & ldquo; Bad marks & rdquo;, This leads to rhubarb teeth. In fact, this is not a problem of the teeth themselves. It is caused by not paying attention to oral hygiene.
3. Aged yellow teeth: with the increase of age, the teeth will age, and the color will gradually darken and turn pale yellow. Time will wrinkle the skin and make the teeth no longer white.
4. The toothbrush is too hard: for the cleaning effect, the hard toothbrush is much better than the soft toothbrush. Although the effect is good, it will damage the enamel on the tooth surface and cause pigmentation. People who often use a hard toothbrush, although the teeth are hard, the color of the teeth will not be too white, so it is recommended that you prepare a soft and a hard toothbrush, and use a hard toothbrush every three days to thoroughly clean the tartar, but do not use a hard bristle toothbrush during menstruation, because the metabolic level of the body is unstable and the enamel is very fragile!

function: it can clean the tooth surface and stimulate the blood circulation of gingival tissue. Improve periodontal tissue health.
2. Bass technology
action Essentials: when washing the lip and tongue surface, the bristles form a 45 degree angle with the tooth surface, and the bristle head points to the gum direction, so that the bristles enter the gingival sulcus and adjacent area, and part of the bristles are pressed on the gingival margin to vibrate back and forth for a short distance. The bristles are tightly pressed on the surface to make the ends of the bristles go deep into the fissure area and vibrate forward and backward for a short distance.
function: it can effectively remove the plaque in the neck and gingival sulcus, massage the gums, and avoid wedge-shaped defect of tooth neck and gingival atrophy.

When brushing the lingual and palatal surface of the front teeth, the tip of the toothbrush bristle bundle shall be directly placed on the lingual and palatal surface of the teeth, the upper teeth shall be pulled down and the lower teeth shall be lifted up. When brushing the occlusal surface of the rear teeth, the tooth bristles shall be placed on the occlusal surface and brushed back and forth.
