14 things you should know about Invisalign


1. Who should I see for my Invisalign treatment

It is important to do your research and make sure you feel comfortable with the dentist who will be treating you, the clinic and the team who will be looking after you. You will all be working closely together for several months so it is important that you have confidence in the team. Any dentist can treat patients using Invisalign, however, an orthodontist specializes in moving teeth with braces and has experience in working with a large range of orthodontic systems which can help, especially if your case is complex. Remember, all orthodontists are dentists; not all dentists are orthodontists.

2. The fees

The fees will vary depending on your individual case and needs however as a guide the investment can range between £3000 and £4500 which is generally based on 12-18 months of treatment. For very complex cases this can be more and there are also simpler treatments for very mild cases that can range from just £1500. 0% interest-free finance is available to help spread the investment over up to 18 months and make treatment more affordable.

3. Will Invisalign work for me?

As with any brace, for Invisalign to work you would need to adjust your lifestyle. The aligners must be worn for no less than 22 hours per day and you must remove them when you eat or drink anything other than cold water. If you are not strict with wearing the aligners, you may be faced with your treatment taking longer than planned or not achieving the best result possible. Most cases are suitable for Invisalign these days, however, there are some cases where only a fixed brace will provide the best result. The great thing about Invisalign is that you can see what the end result should look like before you actually commit to the treatment. This is known as a ClinCheck (3D simulation) which is charged at £350 and is usually deducted from the final balance of the Invisalign treatment fee.

4. How long should each aligner be worn for?

The aligners should be worn for 2 weeks before changing to the next set. Moving teeth should be done at a slow and gentle pace as moving teeth too quickly can cause shrinkage of the roots which can make teeth less stable and become mobile over time.

5. What do the aligners feel like in the mouth?

As movement is fairly gradual with Invisalign, the treatment is generally pain-free. You may notice slight tenderness when you change to the next set of aligners but this is a sign that the teeth are moving as they should be. It will take a few days to adjust to wearing the aligners and adapting to a new routine, as you would expect with anything. Many patients miss their aligners when they finish treatment.

6. Will people notice them?

Although the aligners are clear and virtually invisible, you may find that people notice something different about you but may not be able to pinpoint what it is. The aligners can make your teeth appear shinier and may discolor very slightly as you are getting close to your next aligner change. Many of our patients get through treatment and tell us no-one even knew.

7. Your love life and Invisalign

Life can carry on the same while wearing Invisalign and patients have no problem dating or kissing while wearing the aligners. It is important to keep your teeth and the aligners clean and you can even purchase cleaning tablets that dissolve in water to soak them regularly so they stay nice and fresh.

8. Will Invisalign cause me to speak differently?

There may be a temporary change to your speech initially while getting used to your new aligners, however, this subsides after a few days once your tongue gets used to them being there.

9. What are Invisalign attachments?

Invisalign attachments are a necessary part of Invisalign treatment. They allow the aligners to get more grip in certain areas where teeth may need more complex movement. We use tooth-colored composite that is removed after your treatment and as long as you are wearing your aligners as instructed, they are virtually invisible.

10. What is Interproximal Reduction?

In modern-day orthodontics, we try and avoid removing healthy teeth to create space for teeth to be realigned. Where possible, we use a technique called “Interproximal reduction” or “Interproximal stripping”. We use a special technique that carefully and accurately removes a fraction of a millimeter from your enamel. This procedure is safe in skilled and experienced hands such as Dr Hirani’s. It allows us to make sufficient room to tuck your teeth in line and make them straighter. It is not harmful to the teeth in any way and the procedure itself is not in any way painful.

11. How to keep your aligners clean?

The best way to clean your aligners is with a very soft toothbrush and a small amount of your daily toothpaste. You can also purchase cleaning tablets that dissolve in water to use occasionally if you feel that your aligners need freshening up.

12. Eating and drinking during Invisalign

The main benefit of Invisalign is that you can continue eating all the foods you enjoy and do not need to make any changes in your diet. You may need to change your lifestyle and the times of day you eat, drink and snack. You must never wear your aligners while eating or drinking anything other than cold water as they can become distorted easily with heat. Anything that contains sugar or acid can sit on your teeth beneath the aligners and will prevent your own natural saliva, that fights bacteria throughout the day, reaching your teeth which can cause plaque or even decay over time. You will also need to clean your teeth and your aligners after every snack, drink or meal.

13. How often will I need to visit the orthodontist?

You will need to attend around every 6-8 weeks to check your progress and be given more aligners. It is normal to be given 3-4 sets at a time. You may also require interproximal reduction at certain intervals throughout your treatment and you will be notified by the orthodontist.

14. Will I need to wear retainers

After any orthodontic treatment, retainers are essential to prevent all your hard work from coming undone and your teeth moving again. You will need to wear retainers for life, permanently. We recommend and fit 2 different types of retainers for our patients as standard. One is a bonded or fixed retainer which consists of a thin wire that is secured behind your front 6 or 8 teeth. The other is a removable “bedtime” retainer that is similar in appearance to your Invisalign aligners and is worn for 2 nights per week in conjunction with a bonded retainer.
