All you need to know about Invisalign

Invisalign is one of the newest advancements in dentistry. The orthodontic device effectively corrects teeth misalignments and bite problems but, just like most relatively new technologies, there are a lot of things that are not known or fully understood about them.

If you have been thinking about getting Invisalign for your orthodontic problem or you are yet to get good Invisalign deals in UK, there are things you should know about Invisalign first, and they are explained in this write-up.

What is Invisalign?

Invisalign is a teeth-straightening option and, unlike braces, Invisalign is virtually invisible. It is an aesthetic option for anyone that has concerns about how they look while straightening their teeth. Invisalign system uses transparent aligners to straighten and realign the teeth, unlike the traditional metal, and bracket system so is an upgrade to the traditional braces in terms of aesthetics.

How does Invisalign work?

Your dentist would take your teeth impressions digitally then send them to the Invisalign company in Juarez, Mexico, where your aligners would be made. The digital scan or your impressions would also be taken then examined by the orthodontic technicians before they create your digital model. The technicians will then use an algorithm to make a product called ClinCheck which would be sent to your orthodontist. The ClinCheck gives your orthodontist about how long your treatment would last and what the outcome of the treatment would look like. Your orthodontist would then make the necessary changes on the ClinCheck. The ClinCheck is a 3D model of your teeth that shows the movement to be done by each set of aligner within two weeks.

People who need to rotate their teeth or pull them down may need tooth–coloured composite attachments that will be bonded to the teeth for their Invisalign treatment to be effective. With these attachments, people would get to notice your aligners more, and you may experience more discomfort because the attachment may irritate when they rub your tongue and cheeks. However, these attachments make your Invisalign treatment faster, and your result more like what is generated by ClinCheck. Your orthodontist may decide to show you the ClinCheck and what your needs before making the changes, so you know what to expect. 

Why should you choose Invisalign?

If you are considering Invisalign, you should go for it because it offers the advantage of comfort, good oral hygiene, and aesthetics.

Benefits of Invisalign

Invisalign offers the following advantages.

  • Comfort

Invisalign does not use the traditional metal brackets and wire system that are sharp around the corners.

  • Aesthetics

Invisalign aligners are clear and almost invisible.

  • Reduced risk

Invisalign does not apply excessive force which may cause the root of the teeth to shrink as is common with traditional braces.

  • Speed

Invisalign treatment is usually faster than braces treatments as they tend to move the teeth at once.

  • Better breath

Invisalign is removable, so you get to remove your aligners when you want to brush and floss so there is a reduced risk of dental problems relating to hygiene such as gingivitis and hyperplasia. With braces, it is quite the opposite as getting around the brackets and wires to clean your teeth would be difficult, leaving you with bad breath.

  • Saves time

There is no need for dental appointments for adjusting any wire or brackets, so this saves you more time as you have fewer dental visits.

  • Result

Invisalign offers teeth movements that are not possible with braces.

  • The aligners are yours for life

You get to keep your aligners, and you can use them as whitening trays or as a mouth guard even after your treatment,

  • Alleviate TMD

Invisalign aligners help to relieve pain, and if they are worn for at least 20 hours every day, they can relieve symptoms of TMD and myofascial.

Disadvantages of Invisalign

Just like any other orthodontic treatment, Invisalign has a few disadvantages, but they are not as much as those for traditional braces.

  • Discomfort

Invisalign is more comfortable than braces, but it could irritate your tongue, lips, and gums.

  • Allergic reactions

Invisalign may cause allergic reaction although this happens rarely and if it does, you will get a refund.

  • Speech issues

You may experience lisping for a few days, but you can always take out your aligners if you have an important thing to do that requires your speech to be perfect.

  • Potential weight loss

Taking Invisalign out to eat may not always be comfortable so most people get to eat less during their treatment which may be an upside if you want to lose weight.

  • Cost

Invisalign cost as much as braces but some orthodontists may charge more for them because of the benefits they offer.

  • Aligners need to be taken out to eat.

You need to take out your aligners before eating or drinking anything other than water.

Traditional braces may also be better for certain cases, but your orthodontist can help you decide which of the treatment option is better for you after examining your teeth.

What is the cost of Invisalign?

The cost of Invisalign depends on several factors such as the experience of the orthodontist, and the cost of living in your area. Depending on the complexity of your case, treatment could cost between £1,140 – £6, 100.

If your insurance plan covers for orthodontic treatment, Invisalign would be covered too, although it may not offer full coverage. Most insurance plans cover up to one-third of Invisalign treatment so it could serve as a down payment while you sort out the rest of your payment with a payment plan you would agree on with your orthodontist.

There is a cheaper option known as Invisalign Express, which uses only ten aligner trays. This option may not be effective for everyone as it can only make small movements on the teeth. Most types of misalignment require between 18 – 50 aligner trays.

How to choose an Invisalign provider

General dentists and orthodontists provide Invisalign treatment. Orthodontists are specialists who have training in moving and adjusting the teeth, but, some general orthodontists have worked with Invisalign for a long time so have more experience in Invisalign treatment. 

When you are searching for Invisalign deals that suit you, ensure you check for Invisalign providers with more experience and Invisalign cases each year. Invisalign has several categories of providers to help you make your selection process easier.

Invisalign providers

  • Preferred providers- those who treat at least ten cases every year
  • Premier providers- those who have treated at least a total of fifty cases and twenty-five within the last six months
  • Elite providers- those who have treated a total of at least three hundred and fifty cases every six months

There is no special educational requirement for any of these categories they are strictly based on the number of cases treated.

Invisalign appointment

An Invisalign appointment is the first requirement for getting treatment. During your first appointment, the impressions of your teeth may be taken with a digital scanner or conventional impressions. Your provider may send you to a lab to get the digital scan. If your provider uses conventional impressions, you may find it a bit uncomfortable. Try to breathe slowly through your nose and distract yourself to help you deal with the discomfort.

The impressions or scan will then be used to make a 3D model of the before and after of your treatment to be made. Your dentist would either approve of the model or make some adjustments before your aligners would be made.

During your appointment, remember to ask for the following.

  • To see your ClinCheck
  • How long your treatment will take
  • How much a replacement will be
  • What to expect after you go home


How often do I need to wear my aligners?

The aligner is removable, but they need to be worn for at least 20 hours every day. Some research has shown that some patients who needed mild correction wore their aligners for eighteen hours daily, and their treatment went as planned.

Recently, Invisalign has said that you can wear each set of aligner for a week, but you have to wear them for at least twenty-two hours within the week.

Age also contributes to how long you need to wear your aligners for them to be effective. A teenager may not need as many hours as adults for their teeth to move as planned because as you get older, it becomes more difficult to realign the teeth and bone. During your teeth treatment, ensure that you visit your orthodontist to check the progress of your treatment and to make the necessary adjustments at regular intervals.

How does Invisalign feel?

Invisalign treatment is not as painful and uncomfortable as treatment with braces, but this does not mean that you would not experience a little pain or soreness. To reduce the discomfort, try not to constantly touch or disturb your aligners when they are in your mouth.

Invisalign does not also cause gum inflammation and root resorption, which are often seen with braces.  Give yourself time, and you would get used to your aligners being in your mouth.

How do I care for my aligners?

There are several Invisalign cleaning agents, but you can simply place your aligners in a bowl that contains water and baking soda whenever you are not wearing them. Try not to let your aligners dry out when they are not in your mouth because this may cause a build-up of plaque on them. Distilled water is preferable in keeping your aligners moist.

You can also scrub the aligners with a toothbrush at least once a week. Do not use toothpaste as this may make them white and more visible.

How often would I change my aligners?

Invisalign aligners are meant to be changed every two weeks. Within the first three days of wearing each set of the aligner, it moves the teeth by .25mm, but you have to keep the aligners on for up to two weeks for the bone also to move because this is more important than the tooth ligament movement.

As the treatment progresses, the chances of relapse increases because it is more difficult to hold the position of the teeth so ensure you wear your aligners for the recommended number of hours daily.

What should I expect after Invisalign?

After your treatment period, you may need a refinement period where a few additional adjustments would be made to your teeth. After this stage, you would have to wear a retainer at night to keep your teeth in their new position.

How long will I wear my retainer?

You may have to wear your retainer for the rest of your life because as we get older, our bite and teeth tend to shift. Wearing your retainer helps you avoid a relapse. Although some people may wear their retainers for some years and maintain retention.

How often will I need to replace my retainer?

Invisalign retainer is durable and last longer than the regular aligner. You can use your retainer for 5 – 10 years, especially when you handle it with care.

How much will it cost to replace a retainer?

Replacing your retainer may cost between £57 – £220, but you do not need to take impressions of your teeth to get the replacement retainer.

Can Invisalign correct my bite?

Invisalign can correct bite problems that even traditional braces may not be able to correct. Wearing Invisalign aligners help improve symptoms of TMJ/TMD, which is related to an improper bite.

Will Invisalign fix an underbite, open bite, crossbite, midline, overbite or diastema?

Yes, it would. Invisalign has now advanced to correct most orthodontic issues, but you need to have an orthodontist who is familiar with correcting these orthodontic issues with Invisalign. Invisalign may not be suitable for misalignment that results from skeletal issues.

What do I do if I forgot to change my aligners?

You can always change your aligners to a new set. The only downside of not changing your aligner to a new set is that your treatment would be slowed down.

Can I eat and kiss with Invisalign?

You have about four free hours daily to do whatever you want. Kissing with Invisalign is not a problem as long as your partner is ok with the aligners being in your mouth, but you can take the aligners out then put them back right in when you are done.

You need to remove your aligners before eating because you might stain your aligners and eating without aligners is even easier. Ensure you clean your teeth before you put your aligners into your mouth.

You may drink with your aligners on, but you would be at risk of staining them and making them more visible.

Do I have to brush differently?

The only difference in cleaning your teeth during your treatment is that you may have to brush and floss more often. This may even make brush and flossing easier for you.

Can I whiten my teeth with aligners?

Yes, you can. Whitening your teeth during your Invisalign treatment may even be the best because your aligners can also serve as whitening trays. The aligners are a better and safer option to use with the whitening gel.

Is there an age requirement for Invisalign?

No, there is none. Anyone can use Invisalign even, teenagers from the age of twelve can use Invisalign Teens to straighten their teeth.

Is Invisalign safe for pregnant women?

Yes, it is. During pregnancy, the hormones secreted help to loosen ligaments that surround the teeth, and this makes the teeth straightening process faster.

Could I be allergic to the trays?

In rare cases, allergic reaction to the trays occur, and Invisalign gives a hundred percent refund for this.

What if my teeth are missing?

If your teeth are missing or you will have a tooth extraction, you can still use Invisaligns to straighten your teeth. You can also decide to realign your teeth with Invisaligns before getting dental implants or crowns.

If you want other dental work done in the future, discuss them with your dentist during your first consultation so you can both plan for it.

Will Invisalign affect my speech?

When you start wearing Invisaligns aligners, you may experience lisping, but you would get used to the aligners in no time, and your speech would return to normal. If you are concerned about lisping at work, you may decide to start your new set of aligners on a Friday so that before you go to work on Monday, the lisping would have stopped.

If you have an important event, you may also decide to take out your aligners for a few minutes when you want to speak.

Can I realign just the top or bottom teeth?

No, you cannot. You have to realign both the top and bottom teeth.

Will Invisalign make my breath smell?

Your breath may smell a bit because your saliva would collect in the aligners and the aligners may make your mouth dry out often. Ensure you brush your teeth after every meal and drink a lot of water.

If you notice your breath smell, brush your aligners with a toothbrush and soak them in an Invisalign cleaning solution.

How often do I have to visit my Invisalign provider?

When you start wearing your aligners, you would need to see your Invisaligns provider every four to six weeks to check the progress of your treatment, then take your next set of aligners.
