Your Most Common Questions, Answered
Thinking about Invisalign? Here are the answers to the most frequently asked questions about clear aligner treatment—so you can make an informed, confident decision.
1. How does Invisalign work?
Invisalign uses a series of clear, custom-made aligners to gradually shift your teeth into better alignment. Each set is worn for 1–2 weeks before moving to the next.
2. Is Invisalign suitable for everyone?
Invisalign can treat most mild to complex alignment issues, but a consultation with an Invisalign provider is the best way to determine your suitability.
3. How long does treatment take?
On average, treatment lasts between 6 to 18 months, depending on the complexity of your case and how consistently you wear the aligners.
4. How often should I wear the aligners?
You should wear your aligners for 20–22 hours a day, removing them only for eating, drinking (except water), brushing, and flossing.
5. Are Invisalign aligners painful?
Most patients feel mild pressure or discomfort for a few days after switching to a new aligner. It’s a sign your teeth are moving as planned.
6. Will people be able to see the aligners?
Invisalign aligners are made from clear, medical-grade plastic, making them virtually invisible when worn.
7. What happens after treatment?
To maintain your new smile, you’ll be given Vivera™ retainers—clear and comfortable retainers designed to keep your teeth in their new position.
8. How much does Invisalign cost?
Prices vary based on case complexity, location, and provider, but treatment typically ranges from £1,500 to £5,000. Flexible payment plans are often available.
9. Can I eat and drink with the aligners in?
Aligners should be removed when eating or drinking anything other than water. This helps avoid staining and damage.
10. How do I clean my aligners?
Rinse your aligners with lukewarm water and brush them gently with a soft toothbrush. You can also use Invisalign cleaning crystals for a deeper clean.
