Which Invisalign product do you actually need? A practical guide to choosing the right one.
Invisalign Lite uses up to 14 aligners and is designed for mild cases. Invisalign Comprehensive provides unlimited aligners for complex cases. The choice depends entirely on what your teeth need - not on preference.
Getting this right matters because Lite costs significantly less (£2,500-£3,500 vs £3,500-£5,500 for Comprehensive), but choosing Lite for a case that needs Comprehensive will leave you with an incomplete result and additional costs to upgrade.

The price gap between Lite and Comprehensive is typically £1,000-£2,000. This is significant, but choosing the wrong product to save money often backfires:
The best approach is getting an honest assessment from your provider. If they say Lite is enough, trust that. If they recommend Comprehensive, it is usually worth the extra cost for a complete result.

Your provider will assess your case during a consultation. As a rough guide: if your teeth need minor adjustments (slight crowding, small gap, minor relapse after previous treatment), Lite is likely sufficient. If you have significant crowding, bite issues, or need teeth moved across both arches, you will need Comprehensive.
If treatment with Lite does not achieve the desired result within 14 aligners, your provider may recommend upgrading to Comprehensive. This usually means additional cost. It is better to get the right product from the start, which is why an accurate initial assessment matters.
For very minor corrections (a single rotated tooth, slight relapse, small gap), Express at £1,500-£2,500 offers excellent value. It uses only 7 aligners and finishes in 3-6 months. But it is only suitable for genuinely simple cases.
Refinements are additional aligners ordered after your initial set to fine-tune the result. With Comprehensive, refinements are included at no extra cost (unlimited aligners). With Lite, you get one round of refinements (up to 14 more aligners). With Express, refinements are not included.
