Pick a toothbrush in just 3 steps
Step 1: The handle should have a non-slip design
If the brush handle of the toothbrush has a non-slip design, it not only makes the hand grip convenient, but also feels comfortable, and it is easy to make the toothbrush head directly reach the plaque area of the tooth, which is convenient for cleaning the teeth.
Therefore, when purchasing a toothbrush, it is recommended to purchase the handle and the head at an angle of 17 degrees to 20 degrees.
Step 2: The brush head should be short and narrow
Many people buy a toothbrush that likes to be long and wide, and thinks that the toothbrush will be clean.
In fact, the short and narrow brush head is more flexible and easier to rotate in the mouth, which makes it easier to clean small parts of the mouth and not leave dead spots.
Therefore, when purchasing a toothbrush, it is recommended to purchase a toothbrush having a brush head length between 2.54 and 3.18 cm and a width between 0.79 and 0.95 cm.
The third step: look at the bristles
First, the bristles should be soft and moderate.
Is the bristles harder or softer? In fact, the soft and hard bristles are the best!
If the bristles of the toothbrush are too hard, although the cleaning power is strong, the damage to the teeth is large;
If the toothbrush bristles are too soft, although it is not easy to cause abrasion to the teeth, the cleaning is not strong enough.
Therefore, the two fold, choose the toothbrush with moderate hardness and softness, not only will not hurt the teeth, but also the cleaning ability is quite strong.
Second, the bristles should be arranged reasonably
The American Dental Association recommends that the more reasonable arrangement of the bristles should be: a brush head with 2-4 rows of bristles and 5-12 bundles of bristles per row.
In addition, the toothbrush should be between 10-12 mm long and 3-4 mm wide, and each bristles should be kept at a certain distance.
Finally, the tip of the brush should be smooth
If the factory does not smooth the tip of the bristles during processing, direct use of brushing may cause damage to human teeth and gums.
If the bristles after cutting are smoothed, this will prevent this from happening and protect the health of the teeth and gums.
