<s>[INST] I am getting a metal retainer later on this year and have been told it has a wire along the front and will affect my speech , I am not confortable wearing it to school and will not compromise on that point however I would be able to wear it from when I got home to when I leave in the morning . All together morning-evening it's around 16-17 hours a and i was just wondering if that was a long enough period of time to wear it without my teeth moving back ? [/INST] Hello,Thanks for consulting HCMRead your query as you have metal retainer yes speech is slightly altered in wearing retainer but I will suggest you to wear your reatainer 24 hours that will effect you more in your treatment and moving your teeth back . I will also suggest you to consult your dentist for follow up visits and maintain proper oral hygiene use chlorhexidine mouthwash regularly .Hope this will help you. </s>
