Thanks all. Her 2 yr old molars are starting to bulge a bit but not cutting just yet. She doesn't seem sick otherwise - no cough, runny nose, skin a good colour, plenty of energy and pretty chipper - but have noticed that occasionally she also smells a bit sick IYKWIM. That kind of stale, musty smell through hair and on skin. Will try baby-safe toothpaste first and then if it's persisting might also check out flossing and consider digestive issues. Thanks again for the tips.

ETA - oh yeah, and no it's not a fruity smelly. Just kind of stale and off
