Um yes so i recently just got a new retainer because my old one was cracked and when i put this new one in it kinda gets stuck and my teeth hurt horribly almost like my teeth are moving should i be concerned?

It should prevent your teeth from moving not the opposite. This retainer is probably too tight but you should get used to it soon. It is almost you wear a new wig, you will feel very tight and uncomfortable at first.

Absolutely. Have your orthodontist adjust it for a passive fit.

Adjustment. Please see your practitioner for an appropriate adjustment. Retainers should be passive. Your's seems to be active, causing undesired tooth movement. kjiGet it adjusted.k
