Are Clear Aligners Right for Me? — Suitability and What We Look At

Clear aligners can be a good fit for many adults and older teenagers who want to address mild to moderate crowding, spacing, or alignment concerns. They are not, however, the right choice for every situation. Whether aligners suit you depends on the kind of movement your teeth need, the state of your gums, your bite, and how consistently you can wear them.

At Sandgate Family Dental we will assess your suitability honestly and explain what aligners can and cannot achieve for your case. To start the conversation, book a consultation online.

What clear aligners are designed to do

Clear aligners are a series of removable, transparent trays that gradually move teeth into a planned position. Each tray is worn for a short period (typically one to two weeks) before changing to the next in the series. Treatment plans are designed in advance using digital scans and modelling.

More information on the general treatment is on our clear aligners page, and our aligners vs braces page compares the two main options.

On this page

Situations where aligners often suit well

  • Mild to moderate crowding of the front teeth
  • Small to moderate spaces between teeth
  • Front teeth that have drifted with age
  • Mild relapse after previous braces
  • Mild rotations and tipping
  • Patients who would prefer a discreet appliance
  • Patients who can commit to wearing aligners 20 to 22 hours a day

Situations where aligners may not be the best option

There are cases where braces, specialist treatment, or surgery is more appropriate. Examples include:

  • More complex tooth movements such as significant rotations of round teeth (canines and premolars)
  • Large vertical movements (intruding or extruding teeth substantially)
  • Significant skeletal bite discrepancies — for example, severe underbites or overbites driven by jaw position
  • Cases needing extractions and large amounts of space closure
  • Patients who cannot reliably wear aligners 20 to 22 hours a day
  • Children whose adult teeth and jaws are still developing

If your situation falls into one of these categories, we will say so honestly and discuss alternatives — including referral to an orthodontist where that is the better fit.

What we look at when assessing you

1. Tooth and gum health

Aligners work best on a healthy mouth. Active decay, gum disease, or significant existing dental problems are addressed first. We may suggest a check-up and clean before treatment starts.

2. The pattern of misalignment

Crowding, spacing, rotations, and tipping all behave differently. We assess which of these movements your case needs and whether aligners can deliver them.

3. The bite

How your upper and lower teeth meet is just as important as how the front teeth look. Some bite changes are within reach of aligners; others sit outside what aligners can predictably do.

4. Existing restorations

Crowns, veneers, large fillings, and bridges can affect how aligner attachments are placed and how the teeth respond. We work around them and explain what is realistic.

5. Compliance

This is the single biggest factor in aligner success. Aligners only work when they are worn. If you cannot commit to 20 to 22 hours per day, results will be slower, less predictable, or may not happen at all. We will be straight with you about this at the consultation.

6. Age and growth

Aligners are commonly used in adults and older teenagers whose growth is largely complete. For younger children we usually prefer an early orthodontic assessment rather than aligners.

Complexity limits

Clear aligners have improved significantly over the past decade, but they are not unlimited. As a general guide:

  • Mild cases — small amounts of crowding or spacing, minor relapse — are often well within aligner range.
  • Moderate cases — typical crowding, mild bite issues, mild rotations — are often achievable, sometimes with longer treatment time and more attachments.
  • Complex cases — significant skeletal bite issues, large rotations, severe crowding requiring extractions — are usually better managed with braces or specialist orthodontic care.

We do not push aligners into cases that are beyond what they can predictably do. If braces or specialist treatment is more appropriate, that is what we will recommend.

Compliance — what wearing aligners actually involves

It is worth being honest about the day-to-day reality of aligner treatment.

  • Aligners need to be worn 20 to 22 hours per day, every day.
  • They are removed for eating and for drinking anything other than water.
  • They are removed for brushing, flossing, and aligner cleaning.
  • You will need to change trays on schedule (usually weekly or fortnightly).
  • Small tooth-coloured attachments are usually bonded to some teeth for the duration of treatment.
  • Snacking and grazing become harder, because every time you eat, the aligners need to come out and your teeth need a quick clean before they go back in.
  • After treatment, retainers are needed long term to maintain the result.

For many patients this is entirely manageable. For others, the demands of full-time aligner wear genuinely do not fit their life — and that is useful to know up front.

Common bite considerations

Some bite features influence whether aligners are a sensible choice:

  • Deep bite (front teeth overlap heavily) — often within aligner range with careful planning
  • Open bite (front teeth do not meet) — sometimes manageable, sometimes specialist
  • Crossbite — depends on whether it is dental or skeletal
  • Overjet (upper teeth protrude over lower teeth) — depends on the cause
  • Class III bite (lower jaw protrudes) — often specialist territory

We will explain what your bite looks like and what aligners can predictably do for it.

Appointment

What to expect at a suitability consultation

A typical consultation includes:

  • A discussion of what you want to change
  • A gentle examination of teeth, gums, and bite
  • Photographs and, in many cases, a digital scan
  • An honest opinion on whether aligners can deliver what you want — and, if not, what could
  • A written, itemised plan and quote you can take home

There is no pressure to commit on the day. Many patients take a week or two to think it over.

Alternatives to consider

  • Conventional braces for cases that need more complex movement
  • Dental bonding for small cosmetic concerns that do not really need tooth movement
  • Veneers in certain situations, although the trade-offs are different — see our veneer suitability page
  • Specialist orthodontic referral for complex bite or skeletal issues
Payment

Health funds and payment

We are a HICAPS provider, so for any item covered by your extras we can process the claim on the day and you only pay the gap.

Orthodontic cover is held separately from general dental on most policies, and it has its own annual and lifetime limits. We will provide an itemised plan with item numbers so you can confirm what your fund covers. Our information on orthodontic cover covers this in more detail, and payment plan options are available for many cases.

FAQs

Clear aligner suitability FAQs

Am I too old for clear aligners?

Adult teeth can still be moved at any age, provided gum and bone support are healthy. Many of our aligner patients are well into adulthood.

Will I need attachments?

Most aligner cases use small tooth-coloured attachments bonded to certain teeth. They help the aligners deliver specific movements and are removed at the end of treatment.

How long does treatment usually take?

Treatment time varies based on the complexity of the case. Simple cases may be measured in months; more involved cases run longer. We will give you a realistic estimate at the planning stage.

Do aligners hurt?

Most patients describe a feeling of pressure for a day or two after changing to a new aligner, which then settles. Severe pain is unusual and should be reviewed.

Will I need to wear retainers afterwards?

Yes — retainers are needed long term after any orthodontic treatment. Teeth tend to drift over time, so retainers protect the result of your treatment.

What happens if I lose an aligner?

Please contact us. Depending on where you are in the series, we may ask you to wear the previous or next aligner while a replacement is organised.

How do I find out if aligners are right for me?

Book a consultation. We will examine your teeth, take a scan or impressions if appropriate, and give you a clear answer.
