Clear Aligners

Removable, near-invisible trays that gradually shift teeth into alignment

Clear aligners are a type of orthodontic treatment that uses a series of custom-made, removable plastic trays to gradually move teeth into a more aligned position. They are designed to be worn for 20–22 hours per day and replaced with a new tray every one to two weeks as directed by a treating dentist or orthodontist. Clear aligners can address a range of alignment issues including crowding, spacing, and certain bite irregularities, though more complex cases may require traditional braces. Treatment duration varies widely — from a few months for minor corrections to two or more years for comprehensive cases. A retainer is required after treatment to maintain results.

What the Process Involves

  1. 1

    Initial assessment and records — your dentist or orthodontist takes photographs, X-rays, and digital scans or impressions to assess your bite and plan tooth movements.

  2. 2

    Treatment plan review — a digital simulation of projected tooth movements is prepared; this is a planning tool and not a guarantee of the final outcome.

  3. 3

    Aligner fabrication — your custom aligner series is manufactured and any required tooth-coloured attachments are bonded to your teeth to assist with complex movements.

  4. 4

    Active aligner wear — you wear each set of aligners as directed, attend regular check-up appointments (typically every 6–10 weeks), and progress through the series.

  5. 5

    Retention phase — at the end of active treatment, retainers are fitted to maintain your teeth in their new positions; wear as directed to prevent relapse.

Recovery

Clear aligners are generally associated with less discomfort than traditional braces, though mild pressure or soreness is common after fitting a new tray. Speech may be slightly affected during the initial adjustment period. Oral hygiene is important throughout treatment, as aligners must be removed before eating or drinking anything other than water.

Important Considerations

Treatment success is highly dependent on patient compliance — aligners must be worn consistently as directed. They are not suitable for all cases; your treating clinician will advise whether aligners or braces are more appropriate for your situation. Attachments bonded to teeth during treatment can be visible and may affect aesthetics during the aligner phase. Costs vary between providers and depend on case complexity. Refinements (additional aligner series) may be required if teeth do not move as planned.

Frequently Asked Questions

Can clear aligners fix all types of bite and alignment issues?
Clear aligners are effective for many mild to moderate alignment and spacing concerns, but they are not suitable for all cases. Severe crowding, significant bite discrepancies, or cases requiring tooth extraction may be better managed with traditional braces. A qualified orthodontist or dentist will advise which treatment is most appropriate for your situation.
What happens if I do not wear my aligners enough?
Clear aligners are designed to be worn 20–22 hours per day. Inconsistent wear is the most common reason for treatment falling behind schedule or teeth not moving as planned. If the treatment plan is not followed, refinements (additional aligner series) may be needed, extending overall treatment time.
Will I need retainers after clear aligner treatment?
Yes — retainers are required after any orthodontic treatment, including clear aligners, to prevent teeth from gradually shifting back toward their original positions. Your dentist or orthodontist will advise on the appropriate type and wear schedule for your retainers.
How do clear aligners compare to traditional braces?
Clear aligners offer aesthetic and comfort advantages for many patients, as they are near-invisible and removable. However, treatment success depends heavily on patient compliance, and they may not be suitable for complex cases. Traditional braces may achieve more predictable outcomes in certain situations. Discussing your specific needs with a qualified clinician is the best way to determine which approach is right for you.
