There are a few things you can do to stimulate your gums. First, try to eat a healthy diet that is high in fruits and vegetables. This will help to promote healthy bacteria in your mouth and help to regenerate teeth and gums. Additionally, use a mouthwash that contains baking soda or baking powder to clean your teeth and gums. Finally, brush your teeth regularly with a soft toothbrush and water. This will help to remove plaque and promote healthy dental hygiene.
