Is it normal for a 9 year olds molars to be wobbly?

Yes, it is normal for a 9-year-old's molars to be wobbly as this age often coincides with the shedding of primary teeth. The permanent molars typically begin to erupt around this time, which can cause the roots of the primary molars to dissolve, leading to looseness. However, if there are concerns about pain or unusual mobility, it's best to consult a dentist.
