Oral hygienists usually recommend soft brushes to clean teeth more safely. When brushing irregularly, a hard toothbrush can injury the gums, expose dental cervical lines and then they become sensitive, react to sour or sweet foods, develop decay. If whitening paste with high abrasive particles is used, the negative effect may be stronger.
Moderately hard and hard brushes are usually recommended for patients with prosthetic teeth. In this case, it is worthwhile to have several: soft toothbrush to massage the gums, to clean the tongue and harder toothbrush to care for prosthetic teeth.
The size of the head should also be taken into account. Because some people feel nausea when brushing teeth, especially when it comes to molar teeth. In this case a toothbrush with a small head is more appropriate. This option is also recommended for pregnant women suffering from nausea. In addition, the smaller head makes it easier to reach hard-to-reach places, especially when the brush neck is flexible.
Some heads are covered with a special coating to clean the tongue. There are also whitening brushes: the rubbery between the bristles helps to remove dental plaque. They are highly recommended for smokers, but also suitable for everyone. The arrangement or length of the bristles does not have a significant effect on the quality of teeth cleaning.
But it is important that the brushes do not wear out. It is advisable to change them every 3 months. However, this needs to be assessed individually. Unfolded bristles show the need for a new dental cleanser. In addition, many brushes have a color indicator – other color bristles at the top of the head. When they whiten, become lighter, the brush needs to be changed. Also, replace the toothbrush after infections of the upper respiratory tract (influenza, colds, throat or oral cavity infections).
