Frequently Asked Questions

Do I have to visit a dentist?

We recommend that you visit your local dentist for regular checkups and hygiene appointments every 6-12 months to ensure you maintain optimal dental health.

During your scan and the design process, our registered dentist will confirm when you are suitable for our invisible aligners.

We will monitor your movements weekly with our monitoring app to confirm whether you are ready to move on to the next stage.

Do I keep my used aligners?

Yes, please do not discard your aligners in case one of our dentists advises you to return to a previous stage at any point during your treatment plan.

I previously had braces, will invisible aligners work for me?

Yes. Our invisible aligners can reposition teeth which have moved since having braces.

Will invisible aligners work with crowns?

In some cases, yes, our treatment can work with crowns. However, please advise us before we design your treatment plan so that we are aware.

How do Diamond Whites Invisible Aligners work?

Our invisible aligners are designed to straighten your front 6-8 (excluding molars) teeth by slowly aligning them at different stages throughout your plan. Each aligner will slowly start to move your teeth into position to create your perfect smile.

What if it doesn't work for me?

If your appointed dentist deems you as unsuitable for our Invisible Aligners treatment, you will be refunded for your initial payment.

Does this work with Overbites/Underbites?

In some cases yes, invisible aligners can improve overbites however it is not always possible and this isn't what our aligners are designed to treat. Our main focus is alignment.

Do you offer retainers?

Your retainers will replace the last stage in your aligner treatment and although they look similar to your other aligners, they are made from a stronger material that lasts longer.

We recommend that before starting an invisible aligner treatment with Diamond Whites, you visit your regular dentist to complete any pending dental work and to have a routine check-up and hygiene appointment.

Do I need an X-ray?

X-rays are an important step in diagnosis and when planning your treatment. They are carried out by our registered doctors at Diamond Whites or our Impress partner clinics. If you do not want to have an X-ray, it is possible to proceed with your treatment, but you will have to sign a waiver to do so.
