Is it normal if you can push your bottom retainer out with tongue?

It is not normal if you can push your bottom retainer out with your tongue. If this is happening, it means your retainer is not fitted correctly and may not be providing the proper support and alignment for your teeth. Retainers are custom-made devices that should fit snugly in your mouth and be difficult to move with your tongue or fingers. If you can easily push your retainer out, it is important to see your dentist or orthodontist for an adjustment or a new retainer. A poorly fitted retainer can lead to discomfort and may interfere with the long-term success of your orthodontic treatment.
