Adult asks: must I wear a retainer for life?

I am in my late 30's and had braces removed 10 years ago.  I faithfully
wore the retainer for years, then gradually allowed more time between
inserting it.  I have not worn it at all for maybe two months now, and
my teeth have moved noticeably.

I read another post talking about adult bone growth and shifting
through the years, but I'm wanting to know if it is expected that a
retainer should be worn for life?  I was hoping that a decade would be
sufficient.

Thanks.

retainer must be worn for life or your teeth will shift to some other
position.
You should wear your retainer for about a week or two it will move your
teeth back some. then ask a dentist to make you a permanent bonded
retainer.

Thank you, Dr. Vasserman.

I wish I knew about this before getting braces!

May I ask the brief definition of a permanent bonded retainer?
Alexander Vasserman DDS - 22 Jan 2007 00:12 GMT
it is usually a very thin wire bonded on the back of your teeth
starting from one eye tooth going to the next.
usually it is enough to have it on the lower jaw.
Your situation is not hopeless and if it has only been 2 months you can
still correct it.

Not all ortho can be accomplished with stable results because many
times you are not fixing the original culprit that caused your teeth to
be crooked for example mouth breathing, tongue thrusting, airway
obstruction, etc...
Any orthodontist that says they can guarantee  lack of relapse is lying
through their teeth and you should run the other way. Orthodontics will
improve your facial appearance and is sometimes necessary for the
health of the other teeth. These days orthodontists are moving away
from extraction as much as possible but at the same time they are
expanding the arches with caution and only on patients that need this
to prevent TMD or occlusal dysfunction.

Thanks for the good info Steven; I'm glad to hear that some can
dispense with the retainer.  I'm sure every case is unique.

It makes me wonder that if I had braces as a child, then my teeth would
have been better set by now, with less proclivity to shift?

My retainer still fits; when I put it in it is very tight, but loose
enough by morning to be easily removed.  One concern is, does such
back-and-forth movement on the teeth actually weaken their setting in
the jaws?

I'd like to know more about this, if you know of any online resources.
I was under the impression that teeth shifted because of a genetic
predisposition.  The Dr. that applied my braces did say that I was
probably 'grinding' at night, and there are tiny vertical cracks on
some teeth.

The orginal purpose for braces was not so much appearance as to relieve
occasional 'popping' in my jaws.

Thanks.

    I'm treading lightly now, as I don't want to overstep my expertise.
    If you'd had orthodontic treatment before your growth was complete,
your othodontist would very likely have you in retention at least until
growth is completed.  My impression is that age at which orthodontic
treatment has little to do with ultimate stability of the result, but
that growth can change the result, so that the situation will have to be
monitored into adulthood.  Otherwise, I see no particular reason why
starting earlier in itself would have led to a more stable long-term result.

had a patient that after having ortho as a child and having perfect
straight teeth to age 26 after the next four years she developed an
open skeletal bite. She now needs orthognathic surgery otherwise she
can not put her teeth together. Point is just because "growth stopped"
does not mean the jaws will not change. This is not a guarantee. Teeth
continue to move throughout the alveolar process in response to muscle
pull. I have also ran into a dentist that was able to get orthopedic
movement in an adult without surgery. So nothing is in stone.

You would have to show me the money on that one.

    I have heard of this happening in trauma cases, and also in severe
rheumatoid arthritis cases.  But in any case, it seems there should be
an explanation for significant skeletal changes after growth has ended.
 Do you know any back story on this?

    There are orthodontists who actually aim for a stable result.
Sometimes this isn't achievable, but most of the time my ortho buddies
tell me it is.  After a couple of years wearing a retainer, it will
often be possible to dispense with it and see no significant drifting.
    Sometimes this is not possible, but I think most orthodontists will
know when a result is not going to be stable much of the time.  For
instance, if an arch length analysis is done and there is insufficient
space in the jaws, orthodontists will sometimes recommend extraction or
arch expansion.  If the patient or parent objects, the orthodontist will
have ways to work around this restriction.  But it is a compromise, and
often the compromise is stability.
    I do no orthodontic treatment myself and cannot say how often relapse
can be predicted--but I'd bet it's often predictable.  In any case, it
is clear to me that many orthodontic patients stop wearing their
retainers without having significant shifting.
