Review on Electric toothbrush Oral-B Smart 4 4900, black/pink by Kirana ᠌

A pink and a black brush, a charger, and two nozzles that have never been used are included in this set. Additionally, there is a container that can hold the individual nozzles for up to four members of the family. Two minutes are provided for scrubbing the mouth, after which multiple intermittent signals are issued, but the brush does not turn off and instead continues to function, and two minutes is believed to be the bare minimum amount of time necessary for brushing your teeth. The head of the toothbrush beeps every thirty seconds to indicate that it is time to move on to cleaning a different section of the tooth surface in the mouth. There are three different modes for brushing: Daily brushing, whitening, and a mode that is gentle on sensitive areas of the oral cavity are all recommended under the heading "For sensitive teeth." During the cleaning process, the mode for delicate cleaning is activated when you press the start button for the first time. The mode for whitening is activated when you press the start button for the second time. When strong pressure is applied to the brushes while they are on the teeth, the built-in pressure sensor turns off the pulsation, ensuring that the product can be used safely. As time passes, the blue hairs on the brushes begin to fade, which is a warning that the brush heads need to be replaced. Because the bristles on the brushes are angled in such a way, they are able to remove plaque and debris from areas of the mouth and gums that are otherwise difficult to access. Because of the round form of the brush heads, each tooth will be cleaned on all sides. Once you've used this brush, your teeth will become smooth, there will be no sign of plaque remaining, and the freshness of your breath will last for a longer period of time. The teeth get much whiter.
