Is Invisalign® for Me?

Invisalign® can be used to treat the vast majority of common problems for adults and teens.
Whether your smile needs minor improvements or more extensive adjustments, Invisalign® can certainly help. It's successful in treating overly crowded or widely spaced teeth. It can also relieve more complex issues, including overbites, underbites and even crossbites. In fact, as an Invisalign® Certified Dentist, Arjun can use Invisalign® clear aligners in all or part of just about any treatment plan to help you improve your smile.

Does Invisalign® really work?

Yes! Invisalign® uses 3-D computer imaging technology to depict the complete treatment plan from the initial position to the final desired position from which a series of custom-made, clear "aligners" are produced. This makes the treatment predictable. It really works. Each "aligner" moves teeth incrementally and is worn for about two weeks, then replaced by the next in the series until the final position is achieved.

How long does treatment take?

Treatment takes between 12 and 15 months on average - depending on your specific case (how crooked your teeth are).

What are aligners made of?

Aligners are made of clear, strong medical grade plastic that is virtually invisible when worn.

What do aligners look like?

Aligners are clear and look similar to tooth-whitening trays, but are custom-made for a better fit to move teeth. Some orthodontists and dentists have referred to them as "contact lenses for teeth."

How do I wear the aligners?

You'll wear each set of clear aligners day and night for about 2 weeks, removing them only to eat, drink, brush, and floss.

How often must I come for a review?

You will need to see Dr Kachhala at regular intervals every 6 - 8 weeks in order for him to check your progress and monitor your treatment and to provide you with the next set of aligners. You will be given 3 or 4 aligners to wear until the interval before your next scheduled visit

How does Invisalign® effectively move teeth?

Like brackets and arch wires are to braces, Invisalign® aligners move teeth through the appropriate placement of controlled force on the teeth. The principal difference is that Invisalign® not only controls forces, but also controls the timing of the force application. At each stage, only certain teeth are allowed to move, and these movements are determined by the orthodontic treatment plan for that particular stage. This results in an efficient force delivery system.

What are the primary benefits of Invisalign® compared to other options?

  • Invisalign® is clear. You can straighten your teeth without anyone knowing.
  • Invisalign® is removable. Unlike metal braces, you can eat and drink what you want during treatment. You can also brush and floss normally to maintain good oral hygiene.
  • Invisalign® is comfortable. There are no metal brackets or wires as with braces to cause mouth irritation, and no metal or wires means you spend less time in the dentist chair getting adjustments.
  • Invisalign® allows you to view your own virtual treatment plan before you start? So you can see how your straight teeth will look when your treatment is complete.
  • Teeth whitening on your upper and lower teeth. Invisalign® can be carried out with simultaneous teeth whitening in the latter stages, so you can get your teeth straightened and whitened simultaneously. Teeth whitening with Invisalign® is free at Kenilworth Dental Practice (normally worth £500).

Arjun has been trained using modern Cosmetic techniques to straighten and whiten your teeth. He can assess your specific case and describe the options open to you.

Is this a new way to straighten teeth?

For years, orthodontists and dentists have used removable appliances for limited treatment. Today, with the application of computer technology and custom manufacturing, Invisalign® treats a broader range of cases with greater precision.

How old is the company?

Align Technology, Inc., the company that manufactures Invisalign®, was founded in 1997. Since then, Align has manufactured over 10,000,000 aligners and over 1 million patients have been in treatment.

How old is this technology?

In 1945, Dr. H.D. Kesling envisioned that one day modern technology would enable the use of a series of tooth positioners to produce the kinds of movements required for comprehensive orthodontic treatment. Technology has made this vision a reality. Using advanced computer technology, Align generates Invisalign®, a series of customized clear appliances, called "aligners." Each aligner is worn sequentially by the patient to produce extensive tooth movements in both upper and lower jaws.

How many patients are being treated with Invisalign®?

Worldwide, over 1,000,000 patients have been treated with Invisalign®. The number grows daily.

How does Invisalign® compare to fixed metal wires and braces?

Although there are many choices out there, no other treatment works as comfortably as Invisalign®.

Invisalign® is the best way to transform your smile without interfering with your day-to-day life. The advantages to wearing Invisalign® instead of traditional braces that use fixed brackets and wires are:

  • Invisalign® is also known as invisible braces – nobody can see you are wearing the custom made aligners. Fixed wires are obvious to see.
  • Tooth movements can be visualised through advanced simulation software before you begin. This is unique with Invisalign.
  • Predictable treatment - as Invisalign® is planned in advance Arjun can accurately predict how long your treatment will take, providing the aligners are worn correctly. Treatment time to achieve the desired result is usually quicker compared to wearing orthodontic braces. With Invisalign®, teeth alignment starts right from the beginning.
  • There are no metal wires or brackets to irritate the gums or the inside of the mouth. The comfortable, removable Invisalign® aligners also allow for normal brushing and flossing tasks that are generally impaired by conventional braces.
  • Removable not fixed, allowing you to eat and drink, brush and floss normally. Invisalign® fits in with your lifestyle.

How does Invisalign® compare to Veneers?

Here at Kenilworth Dental Practice, when improving your smile our aim is to correct the position of the upper and lower teeth and improve their appearance in the most conservative way. The most conservative option is orthodontic treatment as unlike veneers, it involves much less drilling to achieve the desired result.
Veneers are custom made laminate porcelains shells that are placed onto the outside surfaces of teeth to give the ‘illusion’ of straighter teeth. Until Invisalign® became available, veneers were a more common treatment option to improve a crooked smile. Now more commonly veneers are used to perfect and finish a smile after Invisalign® treatment has improved the majority of a smile.
Veneers as a standalone option to address a cosmetic issue can have distinct disadvantages that should be considered very carefully before agreeing to treatment.

  • Invisalign® treatment followed by veneers:

Occasionally, veneers can complement and can be used in conjunction with Invisalign® to improve the shape or colour of your teeth after orthodontic treatment. Should you have a chipped, darkened or irregular tooth, veneers can be used to finalise your treatment and perfect your smile after your teeth have been straightened with Invisalign®. If used in combination with Invisalign®, the amount of enamel that needs to be removed may be minimised.

  • Veneers alone without Invisalign®:

Veneers are not a permanent solution. They can chip or break, requiring you to replace them on an individual basis, which can be very expensive. They also have a life expectancy of about 5 to 10 years, depending on the quality of the veneers purchased. Since your tooth enamel has been removed, most patients have no choice but to replace their veneers, incurring the same high costs every time they have to get a new set.

Most importantly, as veneers are a purely cosmetic procedure, they don't correct the position of your teeth or correct bite problems. Instead of straightening teeth as Invisalign® does, a veneer simply covers up the imperfections. Invisalign® offers you naturally beautiful, healthy teeth. It's a solution worth smiling about!
Often, the position of the most crooked teeth, in relation to the rest of the teeth is such that alternative routine cosmetic dental techniques alone (veneers) would not provide a satisfactory result to improve a smile. In order to create space for any new veneer, the entire front surface layer of enamel needs to be removed by up to 1mm. This removal of tooth is not reversible, once removed it cannot be put back as natural tooth enamel is removed to accommodate the thickness of the veneer. When using veneers only as a dental straightening solution, more tooth enamel than necessary may need to be removed.

By having mainly orthodontic treatment to correct the smile, your teeth would require much less aggressive preparation techniques to achieve a better smile. This is far better for the long term health and vitality of your teeth.

I’m only worried about crooked teeth in one jaw-can I straighten this only?

As with most orthodontic treatment, in treating only the jaw where the crooked teeth exist (e.g. lower or upper jaw only), we will be restricted with the degree to which we can perfect the final position of the teeth in this jaw at the end of treatment due to a restriction in space available. So, to accommodate a better final position and appearance for these teeth, we usually treat both jaws. Orthodontic Invisalign® treatment of both your upper and lower jaws is very common and strongly recommended as this will result in a much more stable, more balanced, more aesthetic and predictable final result. 
Our aim is to get everything looking as good as possible to achieve the best final result.

How can I afford the treatment?

Treatment costs vary depending on how crowded your teeth are and how long the treatment might take.

Kenilworth Dental Practice offers a wide range of finance options including 12 months Interest free Credit. Please ask if you would like further details.

We offer complimentary initial chat (normally over £150), and free first retainers after treatment (normally £100-200).

What are retainers?

After completion of the orthodontic treatment you will need to wear a retainer, please note that this is for life if you wish to maintain the final results.
Retention is important as it holds the teeth in their final positions. Orthodontically treated teeth have a tendency to drift back towards their previous positions many years after they have been moved and a retainer will prevent this. 
There are two types of retainer (I) A removable retainer is a clear plastic appliance similar to the aligners. This is worn full time for 6-8 months after treatment, and once the risk of relapse has been stabilised, it is then worn at night only for life.
(II) A fixed retainer is an extremely thin continuous piece of wire bonded unobtrusively to the back surface of the front upper or lower 6 teeth. It is therefore not visible from the front and is hardly noticeable to the tongue. This is also worn for life.
There is usually a choice between the two at the end of treatment.
Sometimes rarely, depending on the complexity in the movements of some teeth, to hold them in their final position more predictably, current research now recommends both types can sometimes be required.
When both are required, the fixed retainer is placed which and on top of this a removable retainer is worn at night only.

We will discuss which type of retainer (or combination) is most suitable for you towards the end of treatment. Please be aware that your teeth may revert back partially to their old positions if you do not wear retainers as instructed.

Do dentists need special training in order to use Invisalign®?

While Invisalign® can be used with virtually any treatment philosophy, specific training is needed. All orthodontists and dentists interested in treating patients with Invisalign® must attend training before cases will be accepted from their office. Over 30,000 orthodontists and dentists worldwide are certified to use Invisalign®, including Dr. Arjun Kachhala here at Kenilworth Dental Practice - ‘Where Smiles Come to Life.’
