We say no to about one in ten enquiries because clear aligners genuinely aren’t the right answer for their case. This isn’t a gimmick — it’s a clinical reality, and it’s better to know early. Here are the seven honest checks we run through at every consultation.
1. Are your teeth mostly in your mouth?
Clear aligners move existing teeth. If you have significant gaps from missing teeth that need restoration, you may need other dental work before aligners are considered. That doesn’t rule you out — it just sequences the work.
2. Are your gums healthy?
Active gum disease (periodontitis) needs treatment before any orthodontic work. Moving teeth through inflamed bone is a bad idea. Your free Smila consultation includes a quick gum check.
3. Is your concern alignment, not size or shape?
Aligners move teeth — they don’t change their size, colour or shape. If you’re mainly concerned about chipping, discolouration, or worn edges, you may want veneers or bonding instead of (or after) clear aligners. We’ll tell you that honestly.
4. Can you commit to 20–22 hours a day?
This is the make-or-break check. Clear aligners only work when they’re in your mouth. If you can’t commit to wearing them through the night, through work, and most of the day — clear aligners won’t deliver. Fixed braces would be a better fit.
5. Do you have a complex bite issue?
Severe overbites, underbites, crossbites, or significant skeletal discrepancies sometimes need traditional orthodontic appliances or surgical input. Our clinician will identify this at consultation and refer you appropriately if so.
6. Are you over 18?
Smila’s pathway is built for adult dentition. We don’t take patients under 18 — younger cases need a paediatric or specialist orthodontic clinic.
7. Are you in good general health?
Most patients with normal medical histories are fine. A few specific conditions (recent radiotherapy to the jaw, bisphosphonate medication for osteoporosis, certain autoimmune conditions) require additional review. Bring your medication list — we’ll ask.
The honest TL;DR
If you have mild-to-moderate crowding, spacing, or relapse from past braces, you’re an adult with healthy gums and you can commit to 20+ hours of wear — clear aligners are very likely a great fit for you. If any of the checks above raise a flag, book a consultation anyway and we’ll tell you straight whether it’s worth proceeding.
