Post-orthodontic retainers, custom-fitted appliances, maintain tooth alignment achieved through prior treatment. A recurring sensation of pressure upon insertion each evening indicates a potential shift in tooth position occurring during the day. This perceived tightness suggests the retainers are actively working to redirect teeth back into their intended, corrected positions.
Consistent retainer use is vital for long-term stability following orthodontic intervention. If teeth shift, even slightly, the retainers prevent further movement and encourage gradual return to optimal alignment. The pressure sensation, while sometimes uncomfortable, signifies the retainers are performing their designated function and preventing orthodontic relapse. Ignoring this sensation and neglecting retainer wear can compromise the initial investment in orthodontic treatment and necessitate future corrective measures.
