IOTN Score Checker
A quick check to estimate how complex your teeth straightening needs might be. For a proper decision, we’ll confirm with a clinician-reviewed photo assessment.
What is IOTN?
IOTN (the Index of Orthodontic Treatment Need) is a scoring system orthodontists use to describe how “medically necessary” treatment might be. It’s less about whether teeth look straight, and more about whether the bite or tooth position could cause problems — like teeth being at higher risk of damage, difficulty biting or chewing, uneven wear, gum issues caused by severe crowding, or certain bite problems.
In simple terms: a lower IOTN need usually means the issue is mostly cosmetic, while a higher IOTN need suggests the teeth and bite may affect health or function. That’s why IOTN is often referenced in NHS pathways and treatment priority. You don’t need to memorise the numbers — the key idea is that there’s a threshold where cases become more “health need” than “appearance”.
This checker uses the same ideas, translated into plain language. It gives helpful guidance, not a diagnosis. A clinician photo review is the fastest way to confirm the true picture and what options are realistic.
Answer the questions to see your likely IOTN score. This is guidance only — a clinician must confirm.
1. Age range
2. Crowding / spacing
3. Bite / jaw relationship
4. Function / comfort
