How many hours do I need to wear my orthodontic retainer?

Posted by Dr. Jorgensen on March 1st, 2011

TimeMy orthodontist told me to wear my retainer every night but my friend has to wear hers 24/7 for the first 6 months. Why the difference? Is there any research to support one approach over the other?

There is no happier day for an orthodontic patient than the day your braces come off. It is the culmination of months of difficult brushing, flossing, watching what you eat, and wearing those pesky rubber bands. The last thing in the world you want is for the teeth to move. So how much retainer wear is really needed?

As I’ve discussed in previous posts, there is no perfect retainer for all patients and no retainer exists that will keep the teeth exactly like they were when the braces came off. In summary, genetics, wear, tongue position, and regular use cause changes that cannot be completely prevented. The purpose of retainers is to minimize these changes.

In the spirit of keeping tooth movement to a minimum, what is the optimum number of hours for retainer wear? According to an article in the European Journal of Orthodontics by Drs. Thickett and Power, there was NO SIGNIFICANT DIFFERENCE between the amount of tooth movement when full-time and part-time (10 hours per day) retainer wear were compared. That was really good news since I have always prescribed that my patients wear their upper retainers nights only after an initial break-in period of 48 hours. Their research confirms what I’ve seen clinically over the years.

Is it possible to wear your retainer too much? In some patients who use the vacuum-formed clear retainers over the front teeth, full-time wear can lead to an anterior open bite (a space between the upper and lower front teeth). The open bite that develops is the same size as the plastic covering the teeth. Typically the teeth will settle back together after the retainer type is changed to one that either covers all of the chewing surfaces or none at all.

Remember that all patients are individuals and nothing works the same for everyone. Be sure and follow the specific instructions that your orthodontist gives YOU! He or she is the best one to evaluate your specific needs.

    Hi Dr,

    I just got my braces off 2 weeks ago and have an Essix retainer. I am supposed to wear it at night only at this point. I just went on vacation and forgot it. I’m considering cutting the vacay a few days short just to get the retainer. There’s no way to have it shipped or anything. So the question is…will it make much difference to not wear it for 4 nights vs 6 nights? Will wearing it more hours when i get back be helpful?

    Hi,

    I just had my braces removed and was told that I need to wear the retainers 24/7 for 6 months. Would it make a difference if I don’t wear them for a few hours each day?
