Do Orthodontists Keep Retainer Molds

Does the orthodontist maintain a sustainable model?

Even if your teeth have not moved, they need to be reshaped. The support is often destroyed during construction. In addition, they will not be able to maintain retention forms for everyone without knowing when and where they will be needed.

I think if one of your teeth has changed and the old form has become unusable, you should rebuild your servants.

Unfortunately, they need to reshape their face. My dentist does this anyway. What can I shout because he has saved me and he is fine

I got my retainer 4 months ago and I wear it 23 hours a day and it's gone. Did the orthodontist make an impression to make a retainer or should I make an appointment and do it? The problem is, I work and it's hard to find free time.

They don't change because I wear them all day, every day.
Even if your teeth have not been moved, they still need to be reshaped. The farm is often destroyed during the booth manufacturing process. In addition, they will not be able to maintain a retention form for everyone without knowing when and when they will be needed.
