Follow this recommended advice:
- Eat a balanced diet.
- Brush with a fluoridated toothpaste twice daily and floss daily.
- Keep your regular preventive visits with your dentist.
- Avoid brushing immediately after getting sick due to morning sickness (use a baking soda rinse to neutralize the acids and then brush after 30 minutes).
- Combat gagging during brushing by using a toothbrush with a smaller head or changing toothpaste flavor.
