DD1 has a similar issue because of a palate expander. She just finished a season of basketball. We ended up not having her wear a mouthguard. She couldn't talk and keep it in and breathe with a mask on. So we rolled the dice on not taking an elbow to the mouth.
Mom to two amazing DDs ('07 & '09) and a fur baby.
Gluten free since Nov '11 after non-celiac gluten sensitive diagnosis. Have had great improvement or total elimination of: migraines, bloating/distention, heartburn, cystic acne, canker sores, bleeding gums, eczema on elbows, dry skin and scalp, muscle cramps, PMS, hair loss, heart palpitations, fatigue. I'm amazed.
