What is Invisalign?

Elements of clear-aligner treatment
ElementPurpose
Clear alignersClear aligners are removable appliances used to move teeth.[2][3]
Treatment planThe plan guides the sequence of tooth movements and reviews.[1][3]

[2][3][1]

Who may consider Invisalign?

Invisalign is a discreet option for people who want orthodontic tooth movement without traditional metal braces. Crooked or crowded teeth can make cleaning harder and contribute to decay or gum disease.

[1][3]

Does it hurt?

Mild discomfort is common for the first few days, and the mouth usually has an adjustment period of about a week. The temporary discomfort can be eased by rinsing with warm salt water.

[1][3]

Is it safe?

The trays are removable for eating, drinking, brushing and flossing, which makes daily cleaning straightforward. They must be worn for the prescribed time so that the gentle pressure can move teeth as planned.

[2][3]

How long does it last?

Each aligner is typically worn for one week and at least 22 hours a day. The total number of trays and treatment time depend on the orthodontic movements required.

[1][3]

How does Invisalign treatment work?

A series of custom-made trays is worn in sequence. Each tray moves teeth a fraction of a millimetre before the next aligner takes over.

[1][3]

What is the adjustment period like?

The trays are not usually made on site, so delivery from the manufacturer can take 4 to 6 weeks. Initial scans, attachments and learning the wear routine are part of getting started.

First alignersAsk how aligners should be worn, removed and cleaned.[1][3]
New alignerAsk which pressure is expected and when the team wants an update.[1][3]

[1][3]

What are the alternatives?

Traditional metal braces are the main fixed alternative. Clear aligners provide a more discreet route for people who prefer a removable appliance.

[1][3]

What should you plan for?

Remove the trays before eating or drinking, then remove them again to brush and floss. Wearing them for at least 22 hours a day leaves only a short daily window without the aligners.

[1][3]

What about insurance and financing in the UAE?

Orthodontic plans that include cover usually cover traditional braces and clear aligners equally, although coverage differs between providers. Treatment cost also reflects the number of aligners and the movements required.

Frequently asked questions

Do I take Invisalign aligners out to eat?
