How Long Will I Need this Retainer?

by

I had braces in my teens. My teeth have done fine in past years but then started to shift again. I went to see a new orthodontist as an adult. He said I had a couple of options. I could re-do braces or wear my retainer again for a while and see if that helps. I opted for the retainer. It does move my teeth back into position. He suggested six months of wearing it full-time, then switching to nighttime wear for an equal amount of time. I followed through on that, but when I “graduated” from the retainer, I noticed that by the next day two of the teeth had shifted again. I’ll put the retainer back in and the cycle repeats. Is there anything I can do about this?

Dear Morgan,

While this isn’t considered “normal” it does happen. For some reason, your teeth aren’t ready to stay in place on their own yet. I have a couple of suggestions for you.

When Teeth Won’t Stay in Place After Braces

You will need to wear a retainer full time for an indefinite period of time. One thing you can do in this case is have a lingual retainer made. This is a retainer which will be bonded to the back of your teeth. This is invisible to everyone else. The downside to this procedure is it is very difficult to get the teeth clean. You will need a floss threader to get in there.

Another option is to use teeth bleaching trays as retainers. These are completely clear so no one will know you are wearing them. They do have the additional benefit of allowing you to whiten your teeth at the same time. Giving you both a straight and white smile simultaneously.

While many cosmetic procedures do require some expertise and post-doctoral training, teeth whitening does not. Any family dentist can do this for you.

My advice is to speak with your orthodontist and discuss these options in depth and decide which you think is best for your situation. It would also be good for him to investigate what is going on with the shifting.

If My Teeth Shift, Do I Re-do Invisalign Treatment?

by

I had an Invisalign treatment when I was in my late teens. I’m in my mid-20s now and my teeth seemed to have shifted. Do I need to re-do the Invisalign treatment?

Missy L. – Pennsylvania

Missy,

First, I’d like to assure you it is normal for people’s teeth to shift. If they didn’t, orthodontics would never work. However, genetics plays a large factor in how much shifting people experience.

It’s likely your dentist provided you with a retainer to wear temporarily after you completed your Invisalign treatment for a specific period of time. If your teeth are shifting you may want to wear that retainer again.

The only reason I would re-do the Invisalign treatment is if your teeth shifted into a position you don’t like. Otherwise, a retainer should do the trick.  Some people have teeth which constantly shift. For those patients, I often recommend a permanent retainer. This is permanently fixed to the back of your teeth. You’ll be able to keep your teeth in proper alignment without worrying about people seeing your retainer.

Talk to your dentist or orthodontist. When they look at your bite, they’ll be able to tell you which treatment is preferable in your case. It’s likely, because your Invisalign treatment was completed in your teens, you’re going to a new dentist. Your old dentist should be able to easily provide any records or information your new dentist need about your Invisalign treatment.

Why Do I Need a Retainer?

by

I just spent four years wearing braces. Do I really need a retainer?

Beth – Kansas City, MO

Beth,

There’s an important reason for retainers after braces. They’re designed to keep your teeth in their new position. If you don’t wear it, your teeth will shift quickly. Retainers are even more important if you’re still growing into adulthood because your growth causes your teeth to shift even more.

Another reason a retainer is necessary is because your new bite needs to stabilize and it may take some time for all of the tissues and the bone to reorganize. Shifting of the teeth occurs naturally so retainers are needed to help keep them in place. Relapse of the teeth is very high the first month after the removal of braces and it usually takes about one year for teeth to stabilize completely after orthodontic treatment. If you had spaces in between your teeth before braces then it takes longer to keep the dentition stable. The rule of thumb is you wear your retainers as long as you wore your braces. So if you wore braces for four years then you wear your retainer for four years.

The good news is not all orthodontic patients need to wear their retainers 24/7. Your orthodontist will recommend what retention plan is best for you. Patients with removable retainers are recommended to wear their retainers on a constant basis for at least the first six months and then usually just at night while they sleep for a few years. Yet some orthodontic patients need only wear their retainers for the first week on a constant basis then after that just at night. A lot of orthodontists apply fixed retainers that are cemented in place to stabilize the teeth which are usually worn for at least five years. This is commonly used for adolescents because it’s common for teenagers not to wear their appliance, plus there’s the possibility of wisdom teeth causing shifting of the teeth while trying to erupt.
