Teeth Bands Versus Invisalign for Gap Between Front Teeth?

Be very careful on this one as there have been some very sad results from unsupervised and even supervised use of teeth bands( which have included tooth loss).  A space can be closed, but the results generally are a trade off of space in another place or a bite problem or even a twist due to inadequate control of the tooth movements.   Invisalign gives good control of all movements and is removable for cleaning and eating and gives much better results in a far safer manner then teeth bands.  Have a Invisalign dentist do a consult on your case and he  can do a digital display facilitated by the company of the end results and the tooth movements.  It is very educational.

You need to tread very carefully when considering OTC methods to treat real dental issues.  There is very little, if any, independant research to verify the safety and efficacy of so many dental products I see sold online.  I have seen patients in my office that have suffered negative consequences from self-treatment using these types of products.  If you want to move forward with treatment, first you need to diagnose why you have the gap.  If you have a muscle attachment that passes through the gap, that must be removed if you plan to keep the gap closed after movement of the teeth.  Second, if you want to close the gap using "bands" you should consider a removeable appliance that acts as an anchor and keeps the elastics in the correct position so they work properly.  This appliance must be worn 23 hours a day (1hour out to eat) for approximately 3 months AFTER the space(s) are fully closed then may be slowly cut back to eventual night wear for retention purposes.  If compliance is an issue, you can consider conventional fixed braces or Invisalign type aligners to correct your issue although they will be more expensive.

I hope this helps to clarify your situation.

If you are referring to placing an elastic between the front two teeth without the supervision of an orthodontist, it is areally bad idea.  You have no control with these elastics, and the other teeth will certainly move.  Invisalign is a way to close spaces in a controlled, slow, safe manner.  You will also need to consider a retainer to keep the space closed once treatment is completed.
