Can I Go on to my Next Invisalign Tray After Less Than 2 Weeks, if my Teeth Fit in It?

Great question!  As a cosmetic dentist, I have had a lot of patients that have asked this same question.  I always say the same thing.  It is more important to move your teeth at a consistently slow and gentle pace.  Your teeth are anchored into your maxilla (upper jaw bone) and your mandible (lower jaw) by your tooth roots.  Moving your teeth too fast can cause tooth root resorption (or shrinkage).  Over time, these shortened tooth roots make your teeth less stable.  This decreased stability can make your teeth become mobile (you would be able to wiggle them with your finger or tongue).  This increase tooth mobility makes them much more likely to become detached and fall out.  So, it's important to not rush your Invisalign trays for this reason.Good luck to you and I hope that this answers your questions.

Invisalign has been around for quite some time. For many years, Invisalign recommended changing trays every two weeks. However, Invisalign CHANGED their recommendation to allow for weekly Invisalign trays in recent years. The length of time - one week or two weeks - will be recommended by the dentist.
Orthodontics is planned in stages. During certain stages, two weeks may be recommended while weekly changes may be recommended during other stages. So, I would not be surprised if your Invisalign specialist changes from two weeks to one week (or vice versa) during treatment, based on the desired tooth movements at that particular stage.

Hi there,
That's great that your teeth move so fast!  But what's going on under the gumline that you don't see:  The bone is slowly reforming around moved teeth.  That means that certain areas of bone around teeth are softer than others.  Keeping the teeth in that position helps grow the bone faster in those areas and you will have a better final result.  Keep course, stick to it and you will be happy in the long run.  Good luck!

New Invisalign protocols state that you CAN change the aligners weekly.  If your previous aligner stills has a tight fit after a week, I recommend wearing it for an additional week before advancing to the next aligner.

Invisalign recently changed their protocol from a minimum of 2-weeks per aligner to now being able to wear each aligner only 1 week. That being said, you always want to follow your dentist's advice on how long you should wear each aligner. Trying to rush the movement may actually have negative consequences. The bone around teeth needs time to heal throughout the movement, and if movement happens too rapidly, it can cause root resorption (meaning the tooth starts to dissolve/shorten on the root side). Always consult with your dentist before you make any changes to the agreed treatment plan.

Technically, the aligners have the ability to complete task in 1 week. This is only obtainable if true 22 hour a day wear time exists. However, every Invisalign specialist may have different preferences regarding this interval. Please always discuss this with your doctor prior to changing interval.

Hi Invisgal,
thank you for the great question.
In 2016 Invisalign changed the clinical policy on the length of wear of each aligner/tray - in used to be two weeks and they switched it to one week now. The explanation was that the clinical research is supporting the data showing that teeth can be moved in the planned position in 1 week which shortens the treatment time with 50%.  In these cases we assume that the patient has been wearing the aligners/trays between 20-22 hours a day.
However, there are some cases that still require a 2 week wearing of each aligner/tray - severely rotated teeth, major crowded teeth and sometimes patients who are older than 55 with specific bone anatomy.
With this being said I really recommend to stick to what your dentist's recommendation is since she/he will determine what will work best for you.
Good luck with your Invisalign treatment,
Dr. Mina Levi 

Great question and thank you for asking it. Recently Invisalign changed its protocols and in a lot of cases patient CAN change aligner in just 1 week. It depends though on difficulty of movement of EACH tooth and only your treating dentist can tell how long you should wear each aligner and when to switch to a new one. Bottom line, straitening teeth now can be done in a lot less time. A lot of them 50% faster.

You should follow the prescription and
instructions that your orthodontist recommends. Even though the aligners often
fit better in less than 2 weeks, switching to the next tray too soon could
cause the aligners to stop fitting properly over time.

So many times we get patients that want to rush their
invisalign treatment…and they ask can I go ahead and move to the next set of
invisalign trays before two weeks. The
recommended time is definitely two weeks. Not just because of how it feels but because its important to give the
biology of our mouth and our body the time to make the changes that are
necessary. Therefore my recommendation
is definitely to stick with…every two weeks. If the trays are being worn consistently and they fit loosely then move
onto the next tray. If you have not worn
them consistently and they’re still relatively tight please wear those extra
time do not move onto the next trays until they feel loose. Two weeks minimum.
