Clear aligners can work well for many patients, but suitability depends on your teeth, bite, goals, and how closely treatment can be followed.

Aligners work by applying sequential light forces — cases that require simple tipping and rotation movements are handled very effectively. ## Cases that need specialist assessment Clear aligners have recognised limitations. Severe crowding (over 8–10mm) may need extractions that aligners handle less predictably than fixed braces. Complex rotations of round teeth (upper canines, lower premolars) are difficult for aligners alone. Significant skeletal discrepancies (jaw position differences) usually need fixed braces or surgery. Active gum disease must be stabilised before any orthodontics. Missing teeth, implants, and bridgework need careful planning. Patients who cannot wear aligners 20–22 hours per day will get poor outcomes — compliance is essential. ## Age and clear aligner suitability Clear aligners are suitable for adults and older teenagers whose teeth and jaws have fully developed. For younger teenagers, specialist aligner systems (Invisalign Teen, Spark Teen) with compliance indicators and additional aligners are available. Children under 12 are rarely suitable for clear aligners. There is no upper age limit — adult aligner cases in their 40s–70s are common and often highly suitable, especially for relapse or mild issues. Gum and bone health is more important than age. ## The importance of oral health before starting Gum disease (periodontitis) must be treated and stable before orthodontic treatment of any kind. Moving teeth in an unhealthy periodontium accelerates bone loss. Your GDP should confirm your gums are healthy before a referral or aligner start. Untreated decay must also be addressed — aligners are not a barrier to decay progression and may worsen it if oral hygiene is poor. Get a dental health check before committing to any orthodontic treatment. ## What a clinical assessment involves A clinician assessing aligner suitability will examine: dental X-rays (to check roots, bone levels, and any buried teeth), bite relationship in three dimensions, amount of crowding and rotation, available space or need for IPR or extractions, gum health and bone levels, existing restorations, compliance potential, and the complexity of tooth movements needed. Photos alone cannot confirm suitability — they are a useful screen for obvious issues, but a full assessment requires clinical examination and X-rays. ## How to get an accurate suitability verdict Submitting photos to a qualified orthodontic clinician is a good first step for early screening. A photo assessment can flag obvious limitations or confirm that an in-person consultation is worthwhile. For complex cases, a consultation with a GDC-listed orthodontic specialist (not just a general dentist offering aligners) gives the most reliable suitability assessment. Specialist training equips them to handle the full range of case complexity and to recognise when aligners alone are not appropriate. ## Useful related pages [Clear Aligners](https://virtualconsultant.online/treatments/clear-aligners) [Best Clear Aligners UK](https://virtualconsultant.online/guides/best-clear-aligners-uk) [Clear Aligners for Crowded Teeth](https://virtualconsultant.online/guides/clear-aligners-for-crowded-teeth) [How to Choose Clear Aligners](https://virtualconsultant.online/guides/how-to-choose-clear-aligners) [Clear Aligners vs Invisalign](https://virtualconsultant.online/guides/clear-aligners-vs-invisalign) [Online Orthodontic Consultation](https://virtualconsultant.online/guides/online-orthodontic-consultation) Clear aligner suitability depends on clinical assessment, records, oral health, bite relationship, and expected tooth movement.

Yes, for mild to moderate crowding — typically up to 5–6mm. Aligners move teeth through sequential tipping and rotation, which handles mild crowding reliably. Severe crowding (over 8–10mm) may require extractions, and aligners are generally less predictable than fixed braces for managing extraction spaces. A clinical assessment with X-rays is needed to determine whether your level of crowding is within aligner range. Am I too old for clear aligners? No. There is no upper age limit for clear aligners. Adults in their 40s, 50s, 60s, and beyond are frequently treated successfully with aligners, particularly for relapse after previous treatment or mild cosmetic issues. The key criteria are healthy gums and bone, healthy teeth, and the ability to comply with wear time. Gum disease must be stable and controlled before starting any orthodontic treatment. Do I need to wear clear aligners all day? Aligners must be worn 20–22 hours per day for most systems (Invisalign, Spark, ClearCorrect, and similar). They are removed only for eating, drinking anything except water, and cleaning. Wearing aligners fewer than 20 hours per day significantly slows treatment, increases the risk of not finishing with the planned number of aligners, and may mean additional refinement aligners are needed. Compliance is the biggest predictor of clear aligner outcomes. Can I have aligners if I have crowns or implants? Crowns can be fitted with aligner attachments, though bonding is less reliable than on natural enamel. Dental implants cannot be moved — the implant is fixed in bone. If an implant is in the wrong position, aligners cannot move it; the treatment plan must work around it. Bridges require careful assessment as they attach multiple teeth together. Always declare all restorations at your consultation — this significantly affects what aligners can achieve. What is the difference between Invisalign and other clear aligners for suitability? Invisalign has the most published clinical evidence and handles the widest range of case complexity — Invisalign Comprehensive is equivalent to full fixed brace treatment for most cases. Short-course systems (Invisalign Lite, SureSmile, smaller brands) are designed for milder cases only. Suitability depends on your specific clinical needs, not the brand name. A qualified clinician should match your case complexity to the appropriate aligner system — not the other way round. Can I have clear aligners if I grind my teeth? Bruxism (teeth grinding) is not an absolute contraindication to clear aligner treatment, but it must be assessed carefully. Grinding increases the rate of aligner wear and can cause the trays to crack, particularly in the molar region where biting forces are highest. Some clinicians find that aligner trays act as a mild occlusal splint during the treatment period, which may reduce grinding forces on tooth surfaces. However, if grinding is severe, a proper occlusal splint should be considered alongside or instead of aligner treatment. Discuss your grinding history openly at consultation so your clinician can factor it into planning and advise on aligner material and thickness appropriate for your situation. Will clear aligners work if I had braces as a teenager and my teeth have moved back? Yes — relapse after previous orthodontic treatment is one of the most straightforward cases for clear aligners. The movements required are typically smaller than the original correction, the teeth are familiar with being repositioned, and the overall case complexity is usually within short-to-medium aligner range. A clinical assessment is still required to confirm the degree of relapse, check gum and bone health, and plan the appropriate course. Many patients who experienced relapse also benefit from a fixed bonded retainer after retreatment to prevent a repeat, which should be included in the discussion from the outset.
