1. Go to the dentist before getting pregnant. (Or in your first trimester)
By going before getting pregnant, it is a good idea to get a checkup. Pregnancy causes swollen gums, which can cause a host of dental issues. Any invasive or elective procedures can be taken care of before pregnancy. But, it is also important to visit the dentist during pregnancy. Many routine procedures such as routine cleanings are safe during pregnancy. X-rays are somewhat controversial so make sure to discuss with your dentist, doctor and to do your research before making an informed decision.
2. Eat enough calcium.
Your baby is a little leach sucking all of your calcium from mama's teeth and bones. But you can stop the calcium stealing by eating a healthy diet and incorporating enough calcium in your diet. Don't worry, babies will only take calcium from mama's reserves if there is insufficient amounts in her diet. Some good non-dairy alternatives include beans, dark leafy greens, salmon and figs.
3. Rinse your mouth often.
After eating snacks or meals, after vomiting, take the time to rinse your mouth. A swig of water will do.
4. Brush at least twice a day.
A good fluoride toothpaste should do the trick.
In the postpartum period this is especially important. You deserve it. Even on those days when it seems like you can't remember the last time you have showered - brush. My routine is that every time I put the baby down to sleep, I take the time to rinse my mouth or brush my teeth.
5. Schedule one last dentist visit just before your due date.
Poor dental health during pregnancy can lead to some pregnancy complications such as preterm birth and low birth weight babies. This is your last chance for awhile to lay down and have someone clean your teeth. I personally love the feeling of fresh clean teeth.
*Some mamas find it uncomfortable to lay down for long periods of time in the final days, so scheduling in the seventh month can solve this problem.
