What do you think is better? A removable lower retainer or a permanent wire bonded to the back of your teeth?

I am going to get my braces off next month and my orthadontist gave me the option of either having a small permanent wire attached to my lower teeth in order to keep them straight or having a retainer for my lower teeth that I could remove. What do you think is better? Which did you have?

Micheal, Micheal, Micheal,
Have you ever heard of super-floss or a floss threader? Your opinion on a fixed lingual retainer is just way off. You don't have to build tarter, get periodontal disease, or accumulate plaque if you take care of your teeth properly in the first place. A person CAN floss correctly with a bonded lingual retainer, however many people CHOOSE not too. This is not the fault of the retainer, it is the fault of the person. A threader or super floss can be threaded right through the teeth and the retainer. No problem. Do you think that a three unit bridge causes perio disease? What does a person use on a three unit bridge to get up under the pontic? A floss theader, super-floss, or a proxy brush. All three can be used depending on the bridge.
As to the question: a fixed is the better choice in my opinion. You have to wear it, no taking it out. You can't lose it. Unless of course it comes un-bonded. However you have to floss every day. Micheal is wrong, the fixed retainer DOES NOT cause any of the problems he described, not properly taking care of your teeth does. That means brushing after every meal, flossing at least once a day, and not eating a ton of carbs and sugar. Ultimately it is up to you and what you think will work best for your lifestyle.
