Who Is a Good Candidate for Clear Aligners?

You may be a good candidate for clear aligners if you have severe to complex teeth alignment concerns, healthy teeth and gums, and can follow your prescribed treatment plan consistently.

Teeth aligners offer a discreet and removable way to address several orthodontic concerns without traditional metal braces.

Clear aligners may be suitable for you if:

  • Crowded Teeth: You have overlapping, crooked or misaligned teeth that need better alignment.

  • Gaps Between Teeth: You want to close spaces between your teeth for a more aligned smile.

  • Bite Issues: You have certain bite concerns, such as an overbite, underbite or deep bite, that may be treatable with clear aligners.

  • Healthy Teeth and Gums: Your oral health is suitable for orthodontic treatment.

  • Consistent Aligner Wear: You can wear your teeth aligners for the recommended 20 to 22 hours a day, as prescribed.

  • A Discreet Teeth Straightening Option: You prefer clear aligners over traditional braces for a less noticeable and removable treatment option.

Which Dental Problems Can Clear Aligners Treat?

Banner Image

Clear aligners are designed to gradually move teeth into planned positions. Depending on the complexity of your case, they may help address the following concerns.

1. Crowded Teeth

When there is insufficient space for your teeth to align properly, they may overlap or appear twisted. Clear aligners may help reposition crowded teeth in suitable cases.

2. Gaps Between Teeth

If you have spaces between your teeth, clear aligners may help move them closer together and improve alignment, depending on the size and cause of the gaps.

3. Crooked or Misaligned Teeth

Teeth that are tilted, rotated or positioned unevenly may be candidates for clear aligner treatment. The type and extent of movement required will influence suitability.

4. Overbite

An overbite occurs when the upper front teeth overlap the lower front teeth more than expected. Certain overbites can be treated with clear aligners, depending on their severity and underlying cause.

5. Underbite

An underbite occurs when the lower front teeth sit in front of the upper front teeth. These dental underbites may be treated with aligners.

6. Deep Bite

A deep bite occurs when the upper front teeth excessively overlap the lower front teeth vertically. Clear aligners may help correct certain deep bites when the case is suitable for aligner therapy.

7. Crossbite or Other Bite Concerns

Some crossbites and other bite irregularities can be treated with clear aligners. The appropriate treatment depends on whether the problem involves tooth positioning, jaw development or a combination of factors.

Not sure which condition you have? Book your free consultation.

Are You Eligible for Clear Aligners Based on Your Age and Dental Health?

Yes. Age alone does not determine whether you can get clear aligners. Your dental development, oral health and individual orthodontic needs matter more.

Are Adults Eligible for Clear Aligners?

Yes, adults are good candidates for clear aligners. If you have crooked teeth, crowding, gaps or certain bite concerns, aligner treatment may be an option even if you did not undergo orthodontic treatment earlier in life.

Can Teenagers Get Clear Aligners?

Yes. Teenagers are eligible for clear aligners if their permanent teeth have developed and milk teeth have erupted.

Do You Need Healthy Teeth and Gums?

Yes. Good oral health is important before beginning orthodontic treatment. Untreated cavities, active gum disease and other dental problems may need to be addressed first. Once these concerns are managed, your orthodontist can reassess whether clear aligners are suitable.

Can You Get Clear Aligners if You Have Crowns, Fillings or Missing Teeth?

Yes. Having existing dental work does not automatically disqualify you from clear aligners. However, crowns, bridges, implants, extensive restorations and missing teeth can influence how your treatment is planned.

Who May Not Be an Ideal Candidate for Clear Aligners?

Clear aligners are not suitable for every orthodontic condition. In some cases, another treatment may provide more predictable results.

You may need additional dental care or an alternative treatment if you have:

  • Complex Tooth Movements: Teeth aligners may be less effective for complex movements, such as rotating teeth by more than 20 degrees, correcting severe tilting, or moving teeth significantly up or down. These cases may require additional orthodontic techniques or alternative treatment options.

  • Large Gaps or Multiple Missing Teeth: Large gaps between teeth or multiple missing teeth can make teeth aligner treatment more challenging. Dental implants cannot be moved like natural teeth, so their presence may also affect treatment planning.

  • Active Gum Disease: Conditions such as periodontitis can weaken the tissues and bone supporting the teeth. Starting orthodontic treatment while gum disease is active may increase the risk of further damage. A dentist or periodontist should treat and stabilise the condition before teeth aligner treatment begins.

  • Untreated Cavities or Tooth Decay: Cavities and other untreated dental problems should be addressed before starting teeth aligner treatment. A dentist can assess your oral health and recommend the necessary treatment to help protect your teeth during orthodontic care.

  • Short or Heavily Worn Teeth: Teeth aligners may be more challenging to use when teeth are very short, significantly worn down, or extensively restored with dental fillings or crowns. In such cases, the aligners may have difficulty achieving the grip needed to guide tooth movements effectively. An orthodontist can assess whether teeth aligners are suitable or if an alternative approach would be more appropriate.

  • Difficulty following wear instructions: Clear aligners are removable, so consistent wear and proper care are important for achieving the planned results.

(Please note: At Toothsi, our clear aligners are designed to address a range of orthodontic concerns, including severe to complex teeth alignment cases, depending on individual suitability and treatment requirements. We also provide jaw alignment treatment options to address certain jaw-related concerns.)

How Do You Find Out if You're Eligible for Toothsi Clear Aligners?

The best way to determine your eligibility is through a professional dental and orthodontic assessment. Here's how the process can help you understand your options.

Step 1: Get Your Teeth Assessed

Your dental concerns, bite, oral health and treatment goals are evaluated to understand the alignment issues that need attention.

Step 2: Get a 3D Scan of Your Teeth

A 3D scan can help capture the position of your teeth and support digital treatment planning. Your clinician may also recommend an examination, dental X-rays or other investigations when required.

Step 3: Receive a Personalised Treatment Plan

An orthodontist assesses your case to determine whether clear aligners are suitable and discusses the expected treatment approach, duration and other relevant considerations.

Step 4: Begin Treatment if You're Eligible

If clear aligners are appropriate for your case, your customised treatment plan will guide your treatment journey. You'll need to follow the prescribed wear schedule and attend recommended progress reviews.

A 3D scan is an important planning step, but it does not by itself confirm eligibility. The final recommendation depends on a clinical assessment.
