What is Invisalign?

Invisalign is a modern-day orthodontic treatment that straightens your teeth, transforming your smile. This align-technology removes the need for traditional braces. The clear Invisalign aligner is transparent and virtually invisible, something brackets and wires cannot offer. A series of custom-made thermoplastic removable aligners shift teeth into their intended position, correcting complex to minor misalignments. We capture an accurate 3D digital scan of your teeth using iTero Element Scanner. This 3D image is then printed using advanced 3D printing technology with medical-grade thermoplastic engineered to ensure a perfect fit. This material is custom-made by heating, pressure adapting, trimming, and polishing. Treatment times vary for each Invisalign option.

Different kinds of invisalign treatment

Invisalign Full
This comprehensive treatment corrects complex and more complicated teeth misalignments that include severe overcrowding, significant gaps, overbites, underbites, cross-bites, and open bites. Invisalign Full usually takes 12 to 18 months. After checking the response and improvement every 4-8 weeks, your next set of aligners will be prescribed and custom-made for you.

Invisalign Lite
If your teeth misalignments are minor, Invisalign Lite can correct them in a shorter time. It can effectively treat mild to moderate malocclusion from slight overcrowding to few gaps in about 6-7 months. Additionally, Invisalign Lite is beneficial to anyone planning to get porcelain veneers in the future and patients suffering from tooth relapse after previously wearing a brace system. The treatment plan consists of up to 14 aligner stages of tooth movement across all teeth with no clinical limitations. It can be applied to either one arch or both arches.

Invisalign Express or Invisalign i7
It is used for cosmetic purposes to correct minimal misalignment, usually a 1mm gap or slight movement of one tooth. If you’ve recently had braces or require minor adjustments, Invisalign Express will perfect your teeth in 3-6 months.

Invisalign Teen
Designed for still developing younger teeth, Invisalign Teen removes the dread of braces and self-consciousness. Children do not have to sacrifice the food they love or activities. They will not feel the social awkwardness that comes with traditional braces. There is no need for them to hide their smiles in social gatherings or photographs. This Invisalign treatment can take up to 18 months, depending on the nature of alignment required. These have blue wear indicators to help gauge wear time and special features to compensate for the eruption of canines, second premolars, and second molars. Replacement aligners are included to counteract misplaced ones.

What are the dental problems Invisalign can solve?


A crossbite is a tooth misaligned bite where the upper teeth fit inside of lower teeth. It can involve a single tooth or groups of teeth at the front, back, or both areas. It isn’t just a misalignment and can cause bone loss, periodontal disease, and teeth degradation. If not corrected at a young age, it can cause lopsided jaw growth, resulting in an unbalanced facial appearance. It can also cause TMJ and sleep apnea.


Known clinically as a Class III malocclusion, an underbite is formed when your lower teeth overlap your upper teeth. A person with an underbite can find it difficult to chew properly and speak clearly. It can cause teeth to wear down quickly. Related issues include chronic jaw or joint (TMJ) pain, chronic mouth breathing, halitosis, and bacterial infections.


An overbite is a condition in which upper front teeth excessively overlap lower front teeth. Most of us have a slight overbite. 5% to 25% overbite is normal. Anything beyond that is known as a deep bite. It can cause teeth to wear down, pain in your jaw, gum disease, difficulty chewing, and even speech problems.

Open Bite

It is a malocclusion usually characterised by a vertical gap between the front upper teeth and lower teeth. When front teeth from the upper and lower jaws do not touch when the mouth is closed, it forms an open bite. It can make it hard to chew or difficult to bite into some common foods.

Gap Teeth

Gap teeth or diastema refers to the space between teeth. These spaces can form anywhere in the mouth, but the most noticeable one is between the two upper front teeth. While some gaps are small and barely noticeable, other gaps are large, causing a cosmetic concern for some people. Some gaps can increase in size over the years.

Crowded Teeth

It is a dental condition that occurs when all your teeth do not fit within your jaw. Teeth can bunch up, overlap, and twist, often getting pushed to the front or the back. It is harder to brush crowded teeth well, resulting in plaque, tartar, and harmful bacterial build-up. It can lead to tooth decay and gum disease.

How does Invisalign work?

Invisalign works to align teeth to an optimum position by applying a controlled force to different parts of the teeth during multiple stages of your treatment. A pushing force acts on each tooth in a prescribed amount and direction, straightening your teeth. It activates osteoclast and osteoblast necessary to move teeth. After the teeth have moved, the aligner becomes redundant, unable to put any more pressure on the teeth. You need a new aligner to move the teeth further. This process is repeated until all aligners in the series are used. To see optimum results, you must wear the aligners for 20 to 22 hours a day.
You can remove your clear aligners to brush your teeth, eat, or dink. You can clean the aligners too to ensure oral hygiene.

Invisalign Timeframe

Your first visit

At your first appointment, we do a smile assessment and help map out a custom treatment plan for you. We take your teeth impressions to create a 3D image. ClinCheck software is utilised to determine the customised treatment for you. The right amount of force and time necessary for every tooth movement is calculated.

Your customised braces are made

Then, Invisalign experts will modify your tooth impressions into a customised aligner. There might be 30 or less than 12 in a series. The numbers vary depending on the treatment you require.

Receiving your Invisalign

On your next visit, you will be provided with your first set of aligners. Some may receive additional sets for wearing before returning for the next visit.

Wearing clear aligners the correct way

You must wear each aligner for the recommended time for each stage, 20-22 hours a day, only removing them for brushing, flossing, eating, and drinking. On each of your visits, we examine how well your teeth are responding to the treatment.

Completing the treatment

The treatment comes to an end when you have worn each aligner in the series recommended for you. To secure your now corrected teeth and perfect smile, have fixed retainers placed.

Aftercare for your Invisalign method

While wearing a retainer is an integral part of aftercare, you need to ensure your beautiful smile is preserved by looking after your oral health.

Keeping teeth clean – Once the aligners come off, make it a habit to brush your teeth twice a day with fluoride toothpaste. A fluoride-based mouthwash gives extra protection to keep the cavities at bay. Straight teeth are easier to clean, so practice the best oral care to maintain your pearly whites.

Routine cleaning and checkups – Regular dental cleaning should be an active part of Invisalign aftercare. Professional cleaning can remove hardened plaque that normal brushing cannot remove. Routine checkups will ensure your teeth and gums are in excellent condition. Our dentists examine your teeth and take X-rays to spot problems early on to prevent expensive treatment for complex issues.

A balanced diet for oral health – A healthy diet contains the necessary vitamins and minerals your teeth need. Fruit, veggies, lean protein, low-fat dairy, complex carbohydrates, and good fats promote oral health. Too much sugar can cause cavities, and a balanced diet will help you stay away from cavity-causing food.

Wear a mouthguard when playing sport – Certain outdoor activities and contact sport carry the risk of dental trauma. A mouthguard will protect your teeth. Over-the-counter boil-and-bite variety will be sufficient for most activities.

Difference between traditional braces and Invisalign


  • Invisalign is clear and virtually undetectable
  • You can remove aligners to clean teeth and gums properly
  • You can remove them to eat and drink
  • Flexibility to decide when you can remove them as long as you wear them for 20-22 hours a day
  • The material is smooth thermoplastic and feels comfortable. There are no metal bits rubbing on your gums, lips, or the inside of your cheeks.

Traditional braces

  • Typical metal braces are noticeable
  • These can only be removed by dental professionals
  • You have to brush your teeth while wearing them
  • Eating and drinking have restrictions as you cannot remove them whenever you want to
  • Routine check-ups and proper maintenance are required in case wires or brackets break

Should I get an Invisalign treatment done?

Yes, it is safe, effective, non-invasive, and non-restrictive. If you have an orthodontic malocclusion and want a barely noticeable solution, you should consider Invisalign.

Will my speech get affected by Invisalign?

It is unlikely. Invisalign aligners are made from thin, flexible plastic and will have little to no effect on your speech.

If I lose an aligner, how can I replace it?

Call your orthodontist right away, and they will advice you on your next step. It is possible to get a replacement soon. If you were new to the aligner you lost, there's a chance you can revert to the one you wore right before the ones you lost. If you were almost at the end of the treatment phase, try wearing the next set of aligners given to you.

What are Invisalign attachments?

They are little, tooth-coloured, barely noticeable bumps made of composite filling material attached to your teeth before or during Invisalign treatment. They serve as an anchor, helping aligners grip the teeth to guide them to their new location. The aligners fit smoothly and tightly around them. Not everyone needs attachments.

Will it be necessary to wear retainers after the Invisalign treatment?

Retainers ensure that teeth do not gradually shift back toward their initial position. After completing orthodontic treatment, whether it is with braces or Invisalign, retainers ensure the alignment lasts. Ask your doctor about the different types of retainers you can use.

Where can I find more information about Invisalign?

Our free no-obligation consultation allows you to discuss the treatment in detail and help you decide which option is best for you.

How long will the Invisalign treatment take before I see results?

Some patients start seeing results in two weeks; others might have to wait three to six months to see visible results.

What should I avoid while undergoing treatment?

  • Eating while wearing your aligners is not recommended.
  • Do not wear aligners without cleaning teeth, especially after eating.
  • Soak your aligner at least once a day in denture cleaner or cleaning crystals made by Invisalign.
  • Clean the aligner with a toothbrush.
  • Make sure to not scratch teeth.
  • Try to minimise hard and chewy foods that may damage or hinder the alignment process.

Is Invisalign treatment worth your money?

Invisalign is costlier than braces. The cost can range from £2000 to as high as £5000, depending on how complex your needs are. However, they have a high barrier to entry. If you have a tight budget and are not worried about aesthetics, traditional braces might be the choice for you.

Can I get Invisalign treatment on NHS?

Orthodontic treatment is not available to adults at the NHS. You will not be offered Invisalign. NHS orthodontic care aims to improve the patient’s dental health and not the aesthetic. Dental work funding is usually only available for children below 18 who meet the treatment criteria.

What is the shortest Invisalign treatment option?

Invisalign Express, which only lasts 6 months, is the shortest. It is designed for minor cases and usually involves only 5 to 10 aligners.

Can the Invisalign treatment be done only for my top teeth?

Yes, single-arch Invisalign treatment is possible after a careful examination to determine that it will not disrupt your bite. In most cases, both arches need to be treated for all teeth to align properly for a stable bite.
