Teeth stay with us throughout our lives. We get our first set when we're tiny, and they should remain with us until we're old. Anyone — at any age — might feel like their teeth should be a little straighter or arched. But there are age limits for braces.

In general, orthodontists recommend that people see the orthodontist at age 7 for their first appointment. This is generally a screening appointment to look for jaw problems or tooth eruption problems. Many times these issues are easier to address before all the permanent teeth come in. However for most people, braces will begin when all the permanent teeth have come in which is about 13 years old.

While there's no official upper limit for braces, your oral health can decline with age. If you're facing some common challenges, such as poor gum health, you might not be healthy enough for braces.

Let's dive into the details about how your teeth change throughout your life, and we'll end with more specifics about the age limits for braces.

Your Teeth in Childhood

We're not born with teeth filling up our mouths. Babies get their nourishment through suckling, and teeth would interfere with that process. But as we age, we develop two sets of teeth.

Our two sets of teeth include:

  • Baby teeth. Young children have 20 teeth, 10 up top and 10 below. The roots dissolve, and they become loose within the mouth and eventually fall away.
  • Adult teeth. By age 13, most people have 28 teeth. These are the teeth that should stay with us throughout the rest of life.

Between ages 17 and 21, some of us develop yet another set of teeth. This last set of four molars sit far back in the mouth. These so-called wisdom teeth aren't present for everyone, and they're not typically considered part of our set of permanent or adult teeth.

Each tooth type does something a little different.

  • Incisors sit at the front of your mouth, and they chop your food into tiny chunks.
  • Canines sit next to your incisors, and they help to break apart meats and other chewy foods.
  • Premolars sit beside your canines, and they grind and crush food.
  • Molars are located at the back of your mouth, and they grind up food even more so it's safe to swallow.

You need all of your teeth to eat food safely without choking or gagging. And they all work together, in perfect unison. They should all be aligned too, so nothing gets caught between them with each bite.

Your Teeth as You Age

You're only given one set of permanent teeth (hence the name). In a perfect world, they'd stay in your mouth for the rest of your life. But health issues are common as we add more candles to our birthday cakes.

As you age, you might deal with:

  • Nerve changes. We rely on sensory information to tell us if we're putting our teeth at risk. But those fibers get smaller as we grow older, and that means we could miss out on cues that we're harming our teeth. Chips and cracks could form as a result.
  • Receding gums. Bacteria, dry mouth, and medications can all interconnect and attack the tissues around your teeth. When that happens, your smile might feel wobbly and unstable. You may even lose a tooth or two.
  • Underlying conditions. Your risk of problems like oral cancer increases with age.

Some people sail into their senior years with a mouth filled with perfectly healthy teeth. But it's clear that you will face mounting challenges to your oral health as the years pass.

In most cases, you must have all of your permanent teeth to get braces, and you must have good oral health to get through treatment.

How Old Is Too Old?

There is no set upper limit for braces. Anyone with permanent teeth in place can sign up for smile-straightening procedures.

But health issues can keep orthodontists from working on your smile. You might face rejection if you are:

  • Missing many teeth. An underlying condition that causes tooth loss should be addressed before you start therapy with braces. Sometimes, it's easier for older adults to move on to dentures or bridges instead.
  • Living with advanced gum disease. Infections and other transient gum problems can be addressed. But if your gums peel away from your teeth, the damage can be permanent. Your doctor may not have enough healthy tissue to move you through treatment with braces.
  • Treating an underlying condition. Some health problems like diabetes don't impact your teeth directly. But they can increase your risk of complications, including problems caused by open sores and bleeding. If your health isn't ideal, your doctor may suggest that you get better before you try braces.

Plenty of older people get braces. Many of them are repeaters. They had braces as younger people, and they need a touchup to pull their teeth back into the right position.

But if your health is not ideal, or you're facing another underlying condition, braces might not be right for you.

How Do Aligners Fit In?

If braces aren't right for you, aligners might be a better choice. But you'll face many of the same age limitation issues.

Aligner companies, just like those that deal with braces, will want all of your permanent teeth in place before they start work. And if you're an older adult, aligner companies will want to ensure that you're in good health before treatment starts.

Byte works hard to remove barriers to treatment. But we do want people to be at least 14 years old before treatment starts, and we'll ask you questions about your health to ensure treatment is right for you.

We can do our assessments via telemedicine, so you don't have to leave your house. We'd love to work with you. Get started today.
