What this quiz is, and what it is not
Clear aligner treatment moves teeth step by step using thin, transparent aligners that are swapped out in sequence. Its success depends on two things: whether your tooth and jaw structure suits this method, and whether you can wear the aligners consistently. The questions below are designed to help you think through the second point and your overall readiness on your own.
This quiz is not a diagnostic tool. It does not produce a score, does not recommend a treatment and does not replace an exam by a clinician. Tooth roots, bone structure, gum health and how the jaws relate to each other can only be understood through an exam and X-rays. The final decision on whether clear aligners are right for you is made only at an orthodontic exam. If you would like to read, for general information, which situations are usually considered suitable for this method, see our article on who clear aligners are suitable for.
Self-assessment questions
Answer each question with yes or no. Writing your answers down will make it easier to talk things through with the orthodontist at your exam.
Wear habits
- Can you wear the aligners 20–22 hours a day, taking them out only to eat and drink (except water)?
- Can you set aside time after every meal to remove the aligners, brush your teeth and clean the aligners?
- Are you ready to cut back on frequent snacking or sipping sugary or acidic drinks throughout the day?
- Can you keep track of switching to a new aligner on set days according to your orthodontist's plan (usually every 1–2 weeks)?
- Can you attend check-up appointments regularly (often every 6–10 weeks)?
Oral health
- Have you had a dental check-up within the past year, and are you free of untreated cavities?
- Are you free of signs such as bleeding or receding gums or loose teeth?
- Can you open and close your mouth comfortably without jaw joint pain, locking or noticeable clicking?
Teeth and bite
- Is what bothers you mostly about how your teeth are lined up (such as crowding, gaps or forward tilting)?
- Are you free of a noticeably receding or protruding jaw in your facial profile?
- Are you free of missing teeth, implants or a large number of crowns? (If you have them, this alone is not an obstacle; it is planned separately at the exam.)
Age and development
- Have most of your permanent teeth come in? (For children, options designed for the growth period, such as Invisalign First, are evaluated separately.)
How should you interpret your answers?
The notes below are only a general framework to help you prepare for your exam. None of them amounts to a result or a diagnosis.
If you answered yes to most questions: Your habits around wearing aligners and your overall readiness appear compatible with clear aligner treatment. This does not mean clear aligners are definitely right for you; your tooth and jaw structure still needs to be assessed. At the exam, a digital scan is taken with iTero, and if you are found to be a suitable candidate, your tooth movements are planned in the ClinCheck software.
If you answered no to some of the wear questions (1–5): With clear aligners, treatment progress is largely in your hands; when the aligners are not worn, the teeth do not move as planned. It is important to talk about this openly at your exam. For some patients, a fixed method may be more practical in daily life. To compare the options, see our page on clear aligners vs. braces.
If you answered no to any of the oral health questions (6–8): Before orthodontic treatment, a cavity, gum or jaw joint problem may need to be assessed and, if necessary, treated. This does not mean orthodontics cannot be done; it means the steps need to be put in the right order.
If you answered no to any of the teeth and bite questions (9–11): Part of the problem may stem from the position of the jawbones. In some skeletal cases, clear aligners can improve how the teeth fit together, but they do not change the bone structure. You can find more detail on our page can clear aligners fix jaw structure.
What can this quiz not pick up?
A self-assessment cannot measure the many factors inside your mouth that cannot be seen with the naked eye. Some information that is decisive for a clear aligner decision only comes to light through an exam and records:
- The position and length of the tooth roots and their support within the bone
- X-ray findings such as impacted or unerupted teeth and cysts
- The skeletal relationship between the upper and lower jaws and their growth potential
- Whether difficult movements such as rotating teeth, vertical movement or root movement are needed
- The effect of habits such as clenching or grinding (bruxism) on the aligners
So even if you answer yes to every question, the outcome may be different at the exam; conversely, even if you answer no to some questions, a suitable plan may still be found. If you are curious about options by age, take a look at our page on what age clear aligners are for.
What to expect during clear aligner treatment
Knowing what treatment looks like in daily life helps you answer the quiz more realistically. In a typical course of treatment, you can expect the following:
- The first days: With each new aligner, you may feel pressure or tightness for a few days. You may have a slight lisp for a short time; for most people it fades within a few days.
- Mealtimes: The aligners come out before eating; after eating, you brush your teeth and put the aligners back in. When you eat out, you should have your aligner case and a toothbrush with you.
- Attachments: Small tooth-colored bumps may be bonded to some teeth; they help the aligners grip the teeth more effectively.
- Check-ups: Your progress is reviewed at the clinic at set intervals; if needed, a refinement phase with additional aligners is planned.
- After treatment: To keep the teeth in their new position, a retainer is worn for a long time, usually at night.
If this routine sounds workable for you, your answers to the wear questions will probably become clearer. For details on daily wear, see our page on how to wear clear aligners.
Who should not put off an exam, whatever the quiz result?
In the following situations, it is better to book an exam directly rather than rely on a self-assessment: ongoing pain or swelling in a tooth or the gums, a loose tooth, pain or locking in the jaw joint, or, in your child, early loss of baby teeth or a noticeable crossbite. These signs may call for other treatment in addition to an orthodontic assessment.
What does it mean if a different method is recommended instead of clear aligners?
At the exam, fixed braces, an orthodontic appliance or a combination of methods may be recommended instead of clear aligners. This does not mean your problem cannot be solved; it simply shows that the tooth movement needed can be achieved more predictably with another method. For example, a palatal expander may be the better fit for a growing child, while fixed brackets may be preferred for an adult who needs significant root movement. In some treatments, the first phase is done with a fixed method and the second phase switches to clear aligners. You have every right to ask why a method is recommended and to compare the options; for general information on orthodontic appliances, see our page on orthodontic appliances.
What should you do after the quiz?
Rather than taking the quiz once and leaving it there, it also helps to answer it again a few days later; answers given in the first burst of enthusiasm, especially to the wear questions, may change over time. Write your answers down and bring them with you to the exam; talking through the questions you answered no to will help the orthodontist choose the right method for you. If you would like a general idea first, you can use the online pre-assessment option and send in your smile photos; it is not a diagnosis either and does not replace an exam. To prepare in advance what you want to ask at the exam, our orthodontic consultation question list page can guide you.
The clinic uses the Invisalign system. If clear aligners are found suitable at the end of the exam, the treatment steps, the likely duration range and your responsibilities are explained to you in detail; if they are not found suitable, other orthodontic options are discussed.
