New baby teeth crossbite

[My2012baby]

Hi all, my almost 1yo DS has only 4 teeth (two upper and to below) but I have noticed that he already has a crossbite, with the lower teeth positioned in front of the upper ones when he closes his mouth. He never used a dummy. I know it's baby teeth and only 4 of them so things are not settled in his mouth yet but I can't help worrying anyways.
Any of you has similar experience or is a dentist? Is it something likely to resolve itself or not? If not at what age do you normally intervene?
TIA

Take him to the dentist to set your mind at rest but it's probably fine. If it's any consolation, their big teeth come in SO differently to their baby teeth it's unbelievable. My DD had beautiful little baby teeth....perfect....now she's almost 9 and has such a huge overbite she needs a brace asap.

I would never have guessed this from her baby teeth....don't worry about it though....see the dentist and he or she will check it out.

You say it's a crossbite but what you describe is more like an underbite I think.

Thanks for the reply! Quite possible I am calling it cross bite and it's not the right term! What I see is the lower 2 teeth coming in front of the upper 2. Will ask my dentist when I go for my appt in a few weeks and see what he thinks

The dental term is "reverse overjet". If you came to see me I would tell you not to worry. We need to wait until adult teeth start to erupt to see what will end up where, even if you see the dentist and its decided that things aren't where they should be, there's nothing that can be done at this age. It's obviously not a huge skeletal abnormality because that would have been noticed before now.

Mrsmorton thanks for you reply, I feel more reassured now. I had a feeling it was something that required permanent teeth to be treated, now my doubts are put to rest thank you. Will keep an eye on it and hope it sorts itself out!
