Or visit the orthodontist. I have late teethers, and our orthodontist doesn’t even like to have baby teeth pulled, but X-rays can show if damage is being done under the gums. If there is crowding, 14 is too late for palate expanders.My dd was 14 before her last (non molar) tooth came down. Sometimes you just need to be patient and let nature do it's work. 9/10 is way to early to worry about perm teeth, imho.
