1. Brush your teeth at least twice a day.
When you brush, don't rush. Take enough time to do a thorough job.

2. Use proper equipment.
Use a fluoride toothpaste and a soft-bristled toothbrush that fits your mouth comfortably. Consider using an electric or battery-operated toothbrush, especially if you have arthritis or other problems that make it difficult to brush effectively.

3. Practice good technique.
Hold your toothbrush at a slight angle against your teeth and brush with short back-and-forth motions. Remember to brush the inside and chewing surfaces of your teeth, as well as your tongue. Avoid vigorous or harsh scrubbing, which can irritate your gums.

4. Keep your equipment clean.
Always rinse your toothbrush with water after brushing. Store your toothbrush in an upright position, if possible, and allow it to air dry until using it again. Don't routinely cover toothbrushes or store them in closed containers, which can encourage the growth of bacteria.

5. Know when to replace your toothbrush.
Invest in a new toothbrush or a replacement head for your electric or battery-operated toothbrush every three to four months — or sooner if the bristles become frayed.
