Usually, the root of the teeth is well anchored in the gum and is therefore well protected from the elements. However, it sometimes happens that it becomes exposed, due to aging or a disease of the gum for example.
Because the dentin covering the root of a tooth is not as strong as the enamel of the crown (the part of the tooth that is normally exposed), some precautions should be taken to avoid damaging it during brushing.
- Use a toothbrush with soft or extra soft bristles.
- With a manual toothbrush, brush with rotating movements and make sure to pass on all the surfaces of the teeth, but don’t brush too vigorously, to avoid damaging the dentin.
- With an electric toothbrush, run the brush on all surfaces without pressing. The toothbrush does all the work, there is no point in "pushing" on it!
- Floss at least once a day. In addition to helping to clean areas between teeth, its regular use contributes to the health of the gums.
You should change your toothbrush (or the head of your electric brush) regularly, as soon as the bristles curl (usually every three months). Allow the bristles to air dry between brushing and never share your toothbrush.
A tooth with an exposed root is usually more sensitive to hot or very cold foods. In addition, acidic foods, including soft drinks, can weaken the dentin of the exposed root. It is better to avoid them or at least reduce their consumption.
Do not hesitate to consult a dentist if you think you have an exposed root. He or she will assess the situation and recommend an appropriate treatment.
