Common Questions & Answers
Find detailed answers to frequently asked questions about Invisalign clear aligner treatments and services
Invisalign Treatment
How long does Invisalign treatment take?
Treatment duration varies depending on your specific case. Invisalign Express takes 3-4 months, Invisalign Lite takes 6-7 months, and Invisalign Comprehensive typically takes 12-18 months for complex cases.
Am I a candidate for Invisalign?
Most adults and teens with mild to moderate orthodontic issues are candidates for Invisalign. We evaluate your teeth alignment, bite, and dental health during your free consultation to determine the best treatment option.
How do Invisalign clear aligners work?
Invisalign uses a series of custom-made, clear aligners that gradually shift your teeth into the desired position. You wear each set of aligners for 1-2 weeks before moving to the next set in the series.
Pricing & Finance
How much does Invisalign cost?
Invisalign Express starts from £2,895, Invisalign Lite from £3,250, and Invisalign Comprehensive from £3,895. We are 60% more affordable than average UK clinics and offer 0% finance options.
Do you accept insurance for Invisalign?
We work with most major insurance providers. Our team will help verify your coverage and maximize your benefits for orthodontic treatment.
What financing options are available?
We offer 0% interest financing plans for up to 12 months and flexible payment options up to 60 months to make Invisalign treatment affordable for everyone.
Treatment Process
What happens during the consultation?
Your free consultation includes a comprehensive examination, 3D digital scan of your teeth, personalized treatment planning, and detailed cost breakdown. We'll show you a preview of your expected results.
How often do I need appointments?
Typically, you'll visit us every 6-8 weeks for progress checks and to receive your next sets of aligners. These appointments are quick, usually taking 15-20 minutes.
Will Invisalign affect my speech?
Most patients experience minimal impact on speech. Any slight lisp typically disappears within a few days as you adjust to wearing the aligners.
Daily Wear & Care
How many hours per day do I wear aligners?
You should wear your Invisalign aligners for 20-22 hours per day, removing them only for eating, drinking (except water), and brushing your teeth.
How do I clean my Invisalign aligners?
Clean your aligners daily using a soft toothbrush and clear, antibacterial soap or the Invisalign cleaning system. Avoid hot water as it can warp the plastic. Rinse thoroughly before wearing.
What foods can I eat with Invisalign?
You can eat anything you want! Simply remove your aligners before eating or drinking anything except water. This is one of the major advantages over traditional braces.
