What Is Invisalign and How Does It Work? A Complete Guide

Straightening your teeth no longer requires uncomfortable metal braces. Invisalign, a modern orthodontic system using clear aligners, has revolutionised how people achieve beautifully aligned smiles—discreetly and comfortably. Whether you’re self-conscious about crooked teeth or simply want a more convenient way to straighten your smile, Invisalign could be the ideal choice.

In this guide, we’ll explore what Invisalign is, how it works, the benefits, and how to begin your treatment by choosing the right Invisalign provider in London.

What Is Invisalign?

A Modern Alternative to Braces

Invisalign uses a series of custom-made clear aligners to gradually move your teeth into their desired position. Each aligner is made from SmartTrack®, a patented thermoplastic material designed for comfort, durability, and subtle appearance.

These aligners are nearly invisible when worn and are easily removable, allowing you to maintain your lifestyle without dietary restrictions or oral hygiene disruptions.

Who Can Benefit from Invisalign?

Invisalign is suitable for:

• Adults and teenagers seeking a discreet orthodontic option
• Patients with mild to moderate misalignment issues, including:
  • Overbite or underbite
  • Crowded teeth
  • Gaps between teeth
  • Crossbite or open bite

Your suitability for Invisalign will be confirmed during your consultation with a qualified provider.

How Invisalign Works – Step by Step

Step 1: Initial Consultation

Your journey begins with a visit to a certified Invisalign provider in London. During this appointment:

• Your teeth will be examined
• 3D digital scans or impressions will be taken
• A personalised treatment plan will be created using Invisalign’s advanced ClinCheck® software

You’ll also be shown a digital preview of how your teeth will move throughout treatment.

Step 2: Custom Aligners Are Created

Once your treatment plan is approved, Invisalign will manufacture a series of aligners, each designed to make slight adjustments to the position of your teeth. Each tray is worn for around 1–2 weeks before moving on to the next.

Step 3: Wearing Your Aligners

You’ll need to wear your aligners for 20 to 22 hours per day, removing them only for:

• Eating or drinking anything other than water
• Brushing and flossing your teeth

You’ll visit your provider every 6–8 weeks for check-ups and to receive your next sets of aligners.

Step 4: Completion & Retention

After completing your treatment:

• You’ll be given a retainer to help maintain your new smile
• Retainers may be removable or fixed, depending on your provider’s recommendation

Without proper retention, teeth can gradually shift back—so this final step is vital.

Key Benefits of Invisalign

Nearly Invisible Appearance

Invisalign aligners are transparent, making them ideal for professionals, teens, and anyone who wants a more discreet option than braces.

Comfortable and Removable

Made from smooth, BPA-free plastic, the aligners are comfortable and don’t irritate your gums or cheeks. Their removability means:

• No food restrictions
• Easier brushing and flossing
• You can remove them for special occasions

Fewer Dental Visits

Invisalign requires fewer adjustment appointments than traditional braces. Digital treatment tracking can also reduce the need for in-person visits.

Invisalign vs Traditional Braces

Aesthetic Differences

• Invisalign: Clear, nearly invisible, discreet in social settings
• Braces: Metal brackets and wires, very noticeable

Lifestyle Considerations

• Invisalign can be removed for meals, meetings, and events
• Braces are fixed and require more effort to maintain hygiene

Treatment Time & Suitability

• Invisalign: typically 6 to 18 months, depending on complexity
• Braces: usually 12 to 24 months
• Invisalign is ideal for mild-to-moderate cases; very complex movements may still require fixed appliances

Tips for Getting the Best Results with Invisalign

Wear Aligners Consistently

Success depends on wearing your aligners as directed—at least 20–22 hours per day. Skipping aligner wear can delay progress or lead to poor results.

Follow Your Provider’s Advice

Regular check-ins help your provider monitor your progress and make any necessary refinements. Some may use attachments or elastics to help guide tooth movement.

Clean Aligners Properly

• Rinse after removal
• Brush with a soft toothbrush and mild soap or Invisalign cleaning crystals
• Avoid hot water, which can warp the plastic

• A detailed, personalised treatment plan
• Access to 3D digital scans and advanced monitoring
