Another good question from the Parent Coaching files: Toddlers who grind their teeth. Why do they do it, and are we -- as parents -- doing anything to cause it? And more importantly, how can we get it to STOP?!
For some, this is a nighttime tendency that seems to be hereditary. For others, it's a passing phase -- and more likely to be heard in the daytime.
Teeth-grinding is usually just a really annoying -- but common and normal -- thing for toddlers. Aside from any medical causes you must rule out first -- dehydration, nutritional deficiencies and pinwoms (yech, I know) being among the rare but true culprits -- it's probably not a reason to worry. It's likely related to all those new choppers growing in -- she's getting used to them. Grinding is a way to feel where they are, make weird new sounds with them, and "sand down" the sharp points that often accompany new teeth. It may also alleviate the pain of teething. PLUS, it's a way to irritate you, if you show it gets under your skin! So watch your reaction -- getting upset about it might be just the fuel she needs to start doing it all the time.
The majority of these cases aren't caused by -- or reflective of -- any parenting flaw. You can think of other ways to occupy her energy, time, and mouth -- like singing, word games, and crunchy snacks. But don't pay too much attention to the grinding itself. My strong recommendation is to IGNORE IT. I know it can be like nails on a chalkboard, but really -- there is no other way. The more you point it out, the more likely she is to increase the grinding. If your toddler still does it frequently after a few weeks, then it's time to have it checked by a good pediatric dentist. But I bet you'll be on to the next parenting dilemma by then.
