Soft toothbrushes are advised because they are gentle on the teeth and gums. Using a toothbrush with hard bristles can actually cause damage to the enamel on your teeth and lead to gum recession.

Soft toothbrushes have bristles that are more flexible and gentle, which means they are less likely to cause damage to the teeth and gums. They can effectively clean the teeth and remove plaque without causing irritation or discomfort.

In addition, soft toothbrushes are recommended for people with sensitive teeth or gums. They can also be beneficial for people who have recently undergone dental procedures, such as tooth extraction or gum surgery.

Overall, using a soft toothbrush is a simple yet effective way to maintain good oral hygiene without causing damage to the teeth and gums.
