Why do permanent retainers break?
If
your permanent
retainer glue came off one tooth , don’t worry as this is
something that can happen. But keep in mind that you need to reach out to your
orthodontist without delay within days. Permanent retainers have an important
job of keeping the teeth aligned after braces or Invisalign. So, you sure don’t
want your beautiful smile and straight teeth to be affected by a broken
retainer. This article will help you know what causes permanent retainer
breaking, what you can do about it, and how is it repaired or replaced by your
orthodontist.
Why
do permanent retainers break?
A permanent retainer is
a piece of metal wire that is bonded with composite resin to the back side of
the teeth, in the bottom or top teeth. Permanent retainers can last up to 20
years with good care. However, they can also be prone to longtime wear and
tear, getting debonded, or breakage.
The
main risk factors that cause a broken permanent retainer include:
- Biting into hard
foods or chewing on ice or hard objects like pencils. It can cause the
wire to bend, the dental composite to come off, or even break the retainer
wire.
- Repeated abrasions
from chewing or brushing in which the composite becomes thin over time or
eventually gets de-bonded.
- The impacts of mouth
and jaw injuries can potentially damage the permanent retainer. This can
occur during a sports activity or a major accident.
- The wire can wear
down over time due to dental pressures, loss of strength, or wear and
tear.
- If you have a bite
issue, the breakage of retainer wire or glue coming off is very likely.
With bite problems, upper and lower teeth and jaws are not aligned and
teeth can come into contact with the retainer repeatedly.
Is
a broken permanent retainer normal?
Composite
resin is a strong dental adhesive that is used to bond the permanent retainer
wire on your teeth. It is the same material used as composite filling to
treat cavities.
Dental
composite is highly effective which keeps your permanent retainer firm in place
on the tooth enamel. But composite is not supposed to last forever and there
can be risks of debonding. Nor does the wire in your permanent retainer which
may break and not resist the heavy pressures in the long run.
