It is essential to brush your teeth twice a day for good oral health.
However, applying too much pressure to your teeth will not whiten them or keep them healthy - in fact, aggressive brushing can damage your gums and even damage your enamel.
If you notice these signs, you are brushing your teeth incorrectly:
- A new toothbrush that has worn out in a few days or weeks;
- The gum line is receding, indented, as if it has been pushed too far away from the tooth;
- Increased sensitivity in the tooth;
- Bleeding when brushing;
- The tooth has changed color and looks dry.
