It is best to follow the doctor's advice.

Because your teeth are too crowded.

If the tooth is not extracted, there is no room for correction.

It can't achieve the effect.

19 years old is not old (I also started orthodontics at 19 years old)

Orthodontics is to put on braces and move orthodontics slowly.

So the teeth will loosen.

After the braces are removed later,

You should wear a retainer for one year to prevent teeth from rebounding.
