Maintaining good oral hygiene involves brushing twice daily with fluoride toothpaste, flossing daily, using an antiseptic mouthwash, and eating a balanced diet. Regular dental visits are also important.

It's best to replace your toothbrush every 3 to 4 months or sooner if the bristles are frayed. A worn-out toothbrush will clean your teeth less effectively.

If you have a dental emergency, such as a knocked-out tooth or severe pain, you should contact your dentist immediately. Rinse your mouth with warm water, apply a cold compress if needed, and avoid taking medications without consulting your dentist.
