If you walk the halls of an elementary school, you’re likely to see a lot of “metal mouths.” Many parents are now opting for early orthodontic treatment, and the American Association of Orthodontists recommends that children see an orthodontist for an evaluation no later than age 7. But research shows there are often advantages to deferring treatment, though decisions are made on a case-by-case basis.
“There’s been a number of studies that have shown for some very common problems that you’re better off waiting until all the permanent teeth have come in first before treatment is started,” said Robert Williams, a board certified orthodontist who teaches at the University of Maryland.
Common problems that fall into the “better-to-defer” category include conditions such as overjets—that’s when teeth protrude or stick out—or crooked teeth that just need simple straightening.
“Many years ago, you wouldn’t do anything until the permanent teeth were all in,” said Antonino Secchi, a professor of orthodontics at the University of Pennsylvania. Now he says if parents opt to treat an overjet early—say at age 9 — the child may end up needing another phase of intervention a few years down the road.
“And at the end, instead of having two years of orthodontics, you end up having four years of orthodontics,” Secchi said.
And he says this can be much more expensive.
“Instead of paying one bill, you pay two bills,” he said.
Evaluating Treatment Options
Orthodontists have varying payment structures. Sometimes families are given a break or a discount on a second phase of treatment.
“You want to get the most bang for the least number of bucks,” Williams said.
So, when parents are trying to decide on the best treatment plan, he said, they should ask questions until they understand the pros and cons of each option.
“I definitely asked a lot of questions,” said Mary Bateman, whose 9-year-old daughter Rachel is being treated for a crossbite. That’s when upper teeth bite down on the inside of the lower teeth. If left untreated, it could lead to problems like damaging the gum tissue.
“This is the kind of problem that we pretty much always treat early,” Williams said.
Other conditions that warrant early intervention include overbites or severe crowding.
In Rachel’s case, the ideal time to intervene is between the ages of 6 and 9.
“When the baby teeth are still in, we have more treatment options because we have more flexibility in moving the teeth,” Williams said.
The Batemans ended up at the University of Maryland orthodontic clinic after an evaluation by another orthodontist recommended an expander to correct the overbite.
“I didn’t just jump into it,” Mary Bateman said.
Over the course of getting orthodontic treatment for her three older children, she learned that expanders aren’t the best option for every case, though many orthodontists recommend them in certain circumstances.
“In some cases, expansion of the upper arch [using an expander] is not a stable position,” Williams said.
He opted to treat Rachel Bateman’s overbite by extracting a few baby teeth and putting on braces to move a problem tooth. Williams says some people don’t realize that expansion may relapse and not hold, so some patients may need to wear retainers indefinitely to maintain the extra space in their mouths.
Form versus Function
Orthodontists have varying approaches, and there isn’t one right way or wrong way to treat a problem. Patients, likewise, have different expectations. Many parents put a strong emphasis on a beautiful smile over fixing functional dental problems. This is the case with Pamika Lee, the mother of 15-year-old Quinique Jones.
“I looked at her teeth today, and they are beautiful,” Lee said. “Perfect.”
Jones is about to get her braces off, and Lee says her daughter’s self-confidence is already improved.
As orthodontists blend aesthetic or cosmetic interventions with the business of fixing dental problems, people who have just marginal cases of crooked or crowded teeth are increasingly opting for treatment. Lee says she’s considering it herself—when she can afford it.
“I may get braces soon,” Lee said.
And she’ll be in good company—the American Association of Orthodontists now says 1 in 5 new patients is an adult.
“Some of my patients are in their 60s and 70s,” Williams said. “It’s never too late.”
