Frequently Asked Questions about Invisalign

Q. Is Invisalign available on the NHS?

Invisalign is not considered to be an essential treatment and therefore it is not made available on the NHS. If cost is an issue, it could still be worth consulting your dentist. Many dentists now offer different payment plans, which make expensive orthodontic work more affordable.

Q. 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.
