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.

Having priced up the same implants on the South Coast I found Dental by Design a lot cheaper . I had my whole top jaw teeth replaced by Dr. Mechoui having been worried by the process I found him and the surgery excellent at making me feel relaxed and informed at all stages. The finished result has exceeded my expectations and I would thoroughly recommend Dental by design to anybody who is thinking about the process. Ps they don’t look anything like’Turkey’ teeth, very natural looking and feeling.

I visited plenty of dental practice before I came to see DBD. They all gave me the sweet talk and complications in having it done. I felt like, with all the complications, it’s not worth going through it. For every complications, there’s a corresponding charge. With DBD, everything was straight forward. On my free assessment, Dr Rob gave me lots of encouragement and reassurance. On the day of my procedure, nurse Elisa and Dr Rob made me feel at home and the feeling of outmost care. The receptionist were all very nice and they new my name as I entered the door. Isabella was so caring even with the aftercare calls. Overall, my experience with them has been well worth it in terms of affordability, skills, quality of care and the friendly and clean atmosphere. I will definitely spread the news about DBD.
