Mamas! Don't forget to take care of your teeth during and after pregnancy! I found out the hard way! I had a cleaning when I was about 12 weeks pregnant and everything was perfect and I just went, my little guy is three months old now, and I have three cavities! A change in hormones mixed with rushed brushing and late-night snacking during feedings all contributed and I haven't had a single cavity in years! My dentist said that dental problems following pregnancy are very common.
