Invisalign

Are you tired of looking at misaligned teeth? You might have considered treatment to improve the look and health of your teeth but been turned off by the idea of conventional bracket-and-wire braces. 

Invisalign is a system that will give you beautiful, straight teeth without the discomfort and appearance of traditional braces.

Customised plastic trays, called aligners, are used to gently bring your teeth into the correct alignment. The aligners are worn at night and throughout the day and are only removed for eating. They are practically invisible, and most people will never know that you are wearing them.

Invisalign is available for both teens and adults. The average treatment plan lasts for about twelve months, but every plan is customised for the individual patient, so yours may be longer or shorter. We will work with you to create your own individual plan and keep you informed of the progress you are making.

Why Invisalign?

Invisalign has numerous advantages over traditional braces:

  • Traditional braces require frequent appointments to tighten the wires and check the condition of the braces. With Invisalign, the appointments are less frequent. Between visits, you simply switch to the next set of aligners, which are created according to the order of treatment planned in advance by your dentist.
  • Invisalign allows you to eat any foods you want without the restrictions on sticky or crunchy foods that are known for damaging the wires and brackets of traditional braces.
  • The wires of traditional braces can poke at your mouth and cause ulcers.

Who Is a Candidate for Invisalign?

Are you concerned about crooked teeth? Do you have a prominent overbite or underbite?

Invisalign can treat these common problems and many others including:

  • Protruding teeth
  • Wide gaps
  • Unusual spacing
  • Crowding
  • Crossbite

Caring for Invisalign

Practising good oral hygiene habits while you are being treated with Invisalign is easy. Remove the aligners and brush and floss your teeth as usual. Brush your aligner and rinse with room-temperature water or use the Invisalign cleaning kit to keep your aligners in good shape and free from bacteria.

Never use hot water to rinse or clean your aligners. The plastic could warp. If this happens, call our clinic immediately. You should also call our clinic if your aligner becomes cracked or is damaged in any other way. A cracked aligner can impede your progress.

It’s important to always brush your teeth following a meal before you replace your aligners. If you replace your aligners without brushing, not only could you cause bacteria to become trapped against your teeth, you could also generate staining and other damage to the aligners.

Please contact our surgery to find out more information. We are happy to arrange a consultation so you can find out whether Invisalign is a good option for you.

Frequently Asked Questions

What happens if I lose an aligner?

Losing an aligner is not the end of the world. What does cause problems is when patients do not replace them. By not wearing your aligner for the right amount of time, you risk disrupting your treatment and prolonging the need to wear aligners. If you do not wear your aligners enough, it could be that ultimately, your treatment does not create the results you want.

If you lose or damage an aligner, it is important that you contact your dentist for advice as soon as possible. They will be able to commission a replacement so that your treatment can continue to a successful conclusion.

Q. Will I have to wear retainers?

Retainers are an essential part of all orthodontic work and the Invisalign system is no different. However, the type of retainer you require will vary depending on the type of treatment you have. Some retainers are removable, others are fixed or bonded into place. But retainers will be a requirement of your treatment, as they will stop your teeth from rebounding into their original positions when you have stopped wearing your aligners.

It can be helpful to ask your dentist in advance what kind of retainers they recommend. Retainers are an overlooked part of the treatment for many patients and the type of retainer required in the future can affect their willingness to undergo treatment. There is also an additional cost for retainers which your dentist should make clear to you at the outset.

Q. Will I need further treatment in the future?

As we mentioned above, retention is an important element in the overall treatment. When using Invisalign, retention is usually required for up to two years, though it is gradually scaled back so that you have to wear your retainers less and less.

Most dentists will also recommend that you take regular check-ups to maintain your oral health and hygiene once your treatment has finished. This means that your investment in your smile is maintained in the future.

Q. What is cosmetic dentistry?

Cosmetic dentistry or ‘Aesthetic Dentistry’ involves dental procedure that improve the appearance of you smile. Treatments can lighten, straighten, repair and re-shape teeth, this is done by using tooth whitening, tooth coloured fillings, veneers, crowns, implants & dentures.

Not only is Invisalign versatile, helping to correct a broad range of dental and orthodontic issues, but it really works. And there are over a million smiles to back that up. But a confident smile isn't the only benefit of correcting your dental issues with custom-made Invisalign aligners—your health can be positively impacted as well. Learn more about several common issues below that an experienced Invisalign doctor can work with you to correct.

Overly crowded teeth: This occurs when there is simply a lack of room within your jaw for all of your teeth to fit normally. When left untreated, overly crowded teeth can cause dental decay, an increase in chances of gum disease, and can prevent the normal function of teeth.

Widely spaced teeth: This occurs with abnormal continued growth of the jaw bone. When teeth are missing, this issue can also be caused by the other teeth shifting due to extra space. Spacing issues in teeth can cause some periodontal diseases.

Crossbite: This occurs when the upper and lower jaws are both misaligned. It causes one or more upper teeth to bite on the inside of the lower teeth, and can happen on both the front and/or the sides of the mouth. This issue can cause wear of the teeth, gum disease, and bone loss.

Overbite: What people commonly refer to as an "overbite" is known to dental professionals as "overjet." It occurs when the upper teeth bite over the lower teeth. It's typically caused by either genetics, bad oral habits, or over development of the bone that supports the teeth. This issue can lead to gum problems or irritation, and/or wear on the lower teeth and can cause painful jaw and joint problems.

Underbite: This occurs when the lower teeth protrude past the front teeth. It's usually caused by undergrowth of the upper jaw, overgrowth of the lower jaw, or both. It can also be caused by missing upper teeth. This issue can prevent the normal function of front teeth or molars which can lead to tooth wear. It can also cause painful jaw and joint problems.

An Invisalign doctor will work with you to create a custom-designed program that will treat your specific dental or orthodontic issue(s). Your treatment program will consist of a full set of 
aligners, made for you, and only you.

And of course, there are other considerations when making the decision to straighten your teeth. Think about how Invisalign can present  a virtually-invisible option to getting the smile you want.

Many patients focus on the end result of their orthodontic treatment and overlook the fact that there is often a lot of work required before you get their teeth to their optimal positions.

For example, if you choose conventional braces, you get the benefit of a relatively low cost option that is proven at generating effective results. So many patients take the attitude that, if they can live with the metal look of the braces, it will be worth it for the reduced cost.

However, these patients often don’t realize that their conventional braces need constant adjustments to remain effective over the long-term. You will need to visit your dentist regularly, so that your dentist can adjust the wires and brackets, to ensure that there is enough tension in place to keep on moving the teeth. Missed appointments can therefore result in having to wear your braces for a longer period than originally intended.

With Invisalign, you will still need to visit your dentist but this is more for updates on your progress. Rather than having to adjust fixed brackets, your dentist simply recommends the right time to move up to the next aligner in the series. Therefore, there is no wasted time or periods at which the pressure on the teeth becomes reduced. As long as the patient wears their aligners for at least 22 hours a day, then treatment times can be as little as 6 months.

Of course, each case needs to be assessed and judged on its own merits by a qualified dentist or orthodontic specialist. The more serious the case, the more time needs to be allowed for the aligners to work. Average treatment time is around 12 months or 24 sets of aligners.

Invisalign has some major advantages over conventional braces simply through its unique patented design. Suddenly, everything that makes conventional braces so uncomfortable has disappeared. The wires, the elastics and the brackets are all replaced by a number of minimalist, plastic aligners. The streamlined design of Invisalign is both simpler to work with and more aesthetically pleasing.

The key to the Invisalign system is that it is designed entirely with the patient in mind. Through a combination of X-rays and photography, our dentist will build up a ‘photofit’ of your teeth and jaw structure. He then transfers these images to the Invisalign laboratory where a highly-trained technician, working closely with our dentist, will develop a computer-generated model of how you want your teeth and your smile to look. By using advanced computer packages, we can evaluate different scenarios and ensure that your teeth are being moved in the most efficient way, to the ideal position.

Therefore, you can see before the treatment begins where you teeth will move to and how your smile will look after the treatment. That gives all of our patients the reassurance they need before they commit to the cost of the full procedure.

Once you and our dentist are both happy that the computer-generated model is showing the right results for you, our dentist will commission the production of the transparent aligners. The aligners, therefore, are designed and built specifically for you and to the exact specification agreed with our dental team dentist.

As more and more adults seek high quality orthodontic work later in life, treatments are becoming more expensive. One of the reasons for this is that orthodontic treatments are designed to achieve more than they used to. Now, not only do they need to be effective, they also need to be aesthetic. Not only do they need to be durable, they also need to be comfortable.

In some ways, therefore, customer demand for more personalised, better quality treatments has led to much more variation in the cost of treatment.

Similarly, newer products that depend on advanced technology can require specialist product training for dentists or orthodontic specialists. Often, dentists will invest in this training themselves and this necessitates an increase in the cost of their services. For the very latest treatments, it may be that only a very small number of dentists have the facilities, equipment and expertise to deliver them – so their services can be in very high demand.

All of these factors mean that good quality orthodontic treatment can be expensive and Invisalign is no exception. Don’t forget, Invisalign is a bespoke treatment, with aligners that are created to fit exactly and precisely to the shape of your particular teeth. It is a far more sophisticated approach than conventional braces requires.

On average, you can expect Invisalign costs to start at around $6000 - $8000 for a straightforward tooth realignment. One of the benefits of Invisalign is that, because the treatment is planned out through computer-generated images at the outset, you always can obtain a full quote from our dentist before the treatment begins. Therefore, you know the costs and time scales before you commit to a full treatment plan.
