Most people with mild to moderate crowding, gaps, or teeth that shifted after braces are good candidates for clear aligners. You also need healthy gums, no untreated cavities, and the habit of wearing your aligners about 20 to 22 hours a day. Severe bite problems, active gum disease, or a jaw that is out of line may need a different plan first, and a dental exam with a digital scan is the only way to know for sure.

This guide walks through the signs that point to “yes,” the signs that point to “not yet,” and what to expect when you get checked. If you live in Springville, Spanish Fork, or Mapleton, it can also help you decide what to ask at your first visit.
What Makes Someone a Good Candidate for Clear Aligners
A good candidate has a tooth problem aligners can fix, a healthy mouth, and the time to wear the trays as directed. All three matter. A perfect smile goal will not work if the gums are inflamed, and healthy gums will not help if the trays sit in a drawer.
Clear aligners are thin plastic trays that move teeth a little at a time. Each new set pushes your teeth closer to the final plan. Because the trays only work while they are in your mouth, your daily habits count as much as your teeth do.
Tooth Problems Clear Aligners Often Fix
Clear aligners handle most common cosmetic and mild bite problems in teens and adults. These are the cases dentists see most often:
- Crowding. Teeth that overlap or twist because there is not enough room.
- Gaps. Spaces between teeth, including a gap between the front two.
- Shifting after braces. Teeth that moved back because a retainer was not worn.
- Mild overbite or underbite. Upper and lower teeth that do not meet quite right.
- Crossbite. Some upper teeth that sit inside the lower teeth when you bite.
- Open bite. Front teeth that do not touch when your back teeth close.
Mild and moderate versions of these problems are the sweet spot. Some more complex cases can still be treated with aligners, often with small tooth-colored bumps called attachments that help the trays grip and turn teeth.
Signs You May Need Another Step First
Some people are not ready for aligners yet, but that does not mean never. Often it means “fix this first, then start.” Here are the most common reasons a dentist may pause:
- Gum disease. Teeth move through bone and gum tissue. If your gums bleed, are puffy, or have pulled back, they need care before teeth can safely move. Our page on gum disease treatment explains what that looks like.
- Cavities or broken teeth. These are usually repaired before the scan so the trays fit well.
- A jaw that is out of line. When the upper and lower jaws do not line up, the cause is the bone, not just the teeth. Aligners alone may not fix it, and a referral to an orthodontist may be the right call.
- Many missing teeth or large bridges. Missing teeth change how the others can move, so the plan may need to include them.
- Dental implants in the way. An implant is fixed in the bone and will not move with aligners. The teeth around it can often still move, so it depends on where it sits.
None of these is a reason to give up on a straighter smile. They are reasons to get a real exam instead of guessing.
Your Habits Matter as Much as Your Teeth
Clear aligners only work when you wear them about 20 to 22 hours a day. That is the single biggest thing you control. You take them out to eat and drink anything other than water, then brush and put them right back in.
Ask yourself a few honest questions before you start:
- Can I keep the trays in through most of the day, even at work or school?
- Will I brush after meals before I put them back in?
- Can I keep track of the case and not wrap trays in a napkin at lunch?
- Will I come in for progress checks?
- Will I wear a retainer at night when treatment ends?
If most answers are “yes,” you have the habits aligners need. If you know you will struggle to keep trays in, tell your dentist. That is useful to know when picking a plan.
Age and Clear Aligners
There is no upper age limit for clear aligners, as long as your teeth and gums are healthy. Adults in their 40s, 50s, and beyond straighten their teeth with aligners. Teeth move in adults just as they do in younger people, though it can take a bit longer.
Teens can be good candidates too, usually once most adult teeth have come in. The main question for a teen is whether they will wear the trays as told. A parent and the dentist can talk through that together at the visit.
CandidPro or Invisalign: Which Fits Your Case
Both CandidPro and Invisalign are clear aligner systems your dentist supervises in person, and many cases can be treated with either one. The right choice depends on how complex your case is, your goals, and your budget.
At our office, we offer both. That means the conversation starts with your teeth, not with a brand. In general, milder cases often have more than one good option, and more complex bite work may point toward one system over the other. If you want the details, our guide to CandidPro vs. Invisalign lays out the trade-offs side by side.
You can also read an overview of both systems on our clear aligners page.
How a Dentist Decides If You Are a Candidate
The only way to know for sure is an exam and a digital scan. Photos and online quizzes can give you a hint, but they cannot see your gums, bone, or bite.
Here is what usually happens at a clear aligner visit:
- You share your goals. Tell the dentist what bothers you about your smile and what you hope to change.
- The dentist checks your mouth. This includes your gums, any cavities, old fillings, and how your teeth meet.
- X-rays if needed. These show the roots and bone that support each tooth.
- A digital scan. A small wand takes a 3D picture of your teeth. There is no messy putty.
- A plan and a preview. The dentist explains whether aligners fit your case, which system makes sense, and what treatment would involve.
If aligners are not the best fit, a good dentist will tell you why and what the next step could be. That might be treating your gums first, fixing a tooth, or seeing an orthodontist for a more complex bite.
Questions to Ask at Your First Visit
Going in with a short list of questions helps you get clear answers. Consider asking:
- Is my case mild, moderate, or complex?
- Do I need any other dental work before I start?
- Which aligner system fits my case, and why?
- How often will I come in for checks?
- What happens if my teeth do not move as planned?
- What will my retainer plan look like after treatment?
- What does my insurance cover, and what are my payment choices?
Clear answers to these questions tell you a lot about the plan and the team behind it.
Frequently Asked Questions
Can I get clear aligners if I have crooked teeth and gum disease?
Usually, yes, but the gums come first. Teeth move through gum and bone, so active gum disease needs to be treated and under control before aligners start. Once your gums are healthy, many people can begin treatment.
Can clear aligners fix a bad bite?
Clear aligners can fix many mild to moderate bite problems, such as overbite, underbite, crossbite, and open bite. Bite problems caused by the jaw bones themselves may need an orthodontist or other treatment. An exam and scan show which kind you have.
Am I too old for clear aligners?
No. There is no upper age limit for clear aligners. What matters is the health of your teeth, gums, and bone. Many adults straighten their teeth with aligners later in life.
Can I get clear aligners if I have a crown or a dental implant?
Crowns are usually fine, since aligners can grip them, sometimes with help from attachments. An implant will not move, but nearby teeth often can. Your dentist will plan around any crowns, bridges, or implants you have.
Do I need to see an orthodontist to get clear aligners?
Not always. Many general dentists provide clear aligners and supervise treatment in the office. If your case is complex, such as a jaw that is out of line, your dentist may refer you to an orthodontist.
