Hii.. My daughter hasnt yet lost teeth or at the age of it.. But her last cleaning they told me alot of her teeth where fused together, and that them being fused will make it harder to fall out, and if the adult teeth are fused when they grow in it will take longer and be more painfull... Idk if the fused teeth are apart of the syndrome or not.. But they mentioned because she has such a small mouth and chin that might be it, that waz before we gotten the diagnosis. Hope that helps
Fused teeth might be something to ask about.
