Let’s say it mal-uh-kloo-zhun. That’s malocclusion – it’s the word that dentists use to describe the misalignment of teeth. When your dentist notices this, they recommend you see an orthodontist, who will then determine if you need braces or another orthodontic treatment to correct your bite.

Our blog receives many questions about braces, retainers and other orthodontic matters for our “Ask an Orthodontist” column, featuring Dr. Ron Maddox, who is a practicing orthodontist at Crossroads Dental Group, a Smile Generation-approved office in Upland, California.

Reader Kristina sent us this question:

“I have a question. I am 28 and had my braces removed at 17. I wore my retainer (which is the clear plastic kind no wires) for about a year after. I’ve had my wisdom teeth removed and recently found my old retainers. I put them both on and at first they wouldn’t even stay on but after 20 minutes they would. It hurt a little and I want to wear them again at night. But my question is… is it wise? Since it has been 10 years, I’m wondering if I could loosen my teeth by making them move back in place so quickly. I read about the possibility of them ripping from the gums? What is best for me to do?”

Here is Dr. Maddox’s reply:

“Dear Kristina,

That is amazing that you found your old retainers still intact! Most patients have a hard time keeping track of them even right after they get their braces off!! The type of retainer you described is made from a very thin sheet of plastic that is carefully molded over a model of your teeth after your braces are removed.

There are 2 reasons that the retainers hurt when you put them on: The retainers may have become slightly distorted since they are very thin & there may have been some slight shifting of your teeth. I don’t believe the retainers will cause the teeth to “rip” from your gums, but they may make your teeth feel loose after you take them off since they are putting pressure on the teeth.

The wisdom you have gained over the past 10 years has served you well—the best decision is to schedule an appointment with your orthodontist so that they can assess the changes that have occurred & help you chose the best option to maintain your beautiful smile & limit any further shifting of the teeth. There have been many technological advances in the fabrication of aligners & retainers over the past decade.

If you have moved to a different city & need assistance finding an orthodontist, you can log on to & we can direct you to a qualified doctor that can help you keep your smile beautiful & healthy for many decades to come.

Keep on Smiling!

Dr. M”
