A confident, straight smile can transform the way you feel and interact with the world. Many adults and teenagers want to straighten their teeth discreetly without the inconvenience or appearance of traditional braces. Invisalign provides a modern, flexible solution with clear, removable aligners that blend seamlessly into everyday life. Whether you are correcting a few alignment issues or seeking a complete smile transformation, Invisalign offers a versatile option suitable for all types of dental concerns.

If you are considering teeth straightening, you may ask: How long does Invisalign take? At Freshdental, we design personalised Invisalign treatment plans to ensure you achieve a straight, confident smile efficiently and comfortably.

What is Invisalign?

Invisalign is a clear aligner system designed to move teeth gradually into their ideal position. Unlike traditional braces, it uses smooth, transparent aligners instead of metal brackets and wires. Each set of aligners applies gentle pressure to guide your teeth step by step.

The aligners are removable, allowing you to eat, drink, brush, and floss without limitations. Invisalign can treat a wide range of dental issues, from simple misalignment to complex bite problems, making it suitable for almost anyone seeking a straighter smile.

How Long Does Invisalign Take?

The duration of Invisalign in London varies depending on several factors, including the complexity of your case and your compliance with wearing the aligners. On average, most patients complete treatment within 12 to 24 months. Some may see noticeable changes in as little as six months, while more complex alignments may take up to 30 months.

Factors That Influence Treatment Duration

Severity of Misalignment

Whether you are addressing minor spacing, crowding, or severe bite issues, the complexity of your teeth affects how long Invisalign treatment takes.

Number of Aligners

Your treatment plan may require multiple sets of aligners. More aligners typically mean a longer treatment duration.

Patient Compliance

Aligners should be worn for 20 to 22 hours per day. Consistent wear ensures teeth move efficiently and prevents prolonging treatment.

Age and Oral Health

Healthy teeth and gums support faster, more predictable tooth movement. Younger adults may experience slightly faster progress, though Invisalign is effective for patients of all ages.

Attachments and Optimisers

Small attachments can be bonded to teeth to help aligners move them more effectively. In some cases, we may also use optimisers to reduce treatment time. You can learn more during our Invisalign open evening, where we discuss the process and answer patient questions.

The Invisalign Treatment Process

Initial Consultation

Your Invisalign journey begins with a consultation at Freshdental. During this visit, your dentist will evaluate your teeth, bite, and oral health. Digital scans or impressions are taken to plan your treatment accurately.

Custom Treatment Plan

Using your scans, a 3D model of your teeth is created. You will be shown a visual simulation of how your teeth will move over time. This allows you to see the expected results before treatment begins.

Wearing Aligners

Aligners are typically worn for one to two weeks per set. You will gradually progress through the series, with each set moving your teeth slightly closer to the desired position.

Regular Check-Ups

Check-ups at Freshdental every six to eight weeks ensure your treatment is progressing as planned. Minor adjustments can be made if necessary to stay on track.

Completion and Retainers

Once your teeth are fully aligned, a retainer is provided to maintain your new smile. Retainers prevent teeth from shifting back and help preserve the results of your Invisalign journey.

Benefits of Invisalign at Freshdental

Choosing Invisalign provides several advantages:

  • Discreet Appearance: Clear aligners are nearly invisible, perfect for adults and teenagers.
  • Comfortable and Smooth: Aligners reduce irritation compared to traditional braces.
  • Removable: Eat, drink, brush, and floss without restrictions.
  • Tailored Treatment: Digital scans and personalised plans ensure precise results.
  • Predictable Outcome: You can see a digital simulation of your final smile before starting treatment.

Invisalign at Freshdental can handle everything from minor adjustments to full smile transformations and bite corrections. Patients also explore alternative treatments for straightening teeth depending on their goals and dental needs.

Maintaining Your Invisalign Treatment

Proper care is crucial to ensure your Invisalign treatment is effective and on schedule.

Wear Aligners Consistently

Keep aligners in for 20 to 22 hours daily, removing them only for eating, drinking, or cleaning your teeth.

Clean Aligners Properly

Rinse aligners with water and gently brush with a soft toothbrush. Avoid toothpaste, which can scratch the plastic and make aligners cloudy. Regular visits for dental hygiene help keep your aligners and smile in excellent condition.

Maintain Oral Hygiene

Brush and floss before putting aligners back in to prevent plaque and staining. Healthy teeth and gums support faster and more predictable alignment.

Attend Regular Check-Ups

Regular appointments at Freshdental allow your dentist to monitor progress and make adjustments if necessary.
