How long does clear aligner treatment take?
Simple spacing or mild crowding can finish in a few months. More involved cases commonly run around a year to eighteen months. Your estimate comes from the digital plan and is given in writing before you begin.
Are clear aligners really invisible?
They are transparent and far less visible than fixed braces, but they are not completely undetectable at conversational distance. Most people notice nothing in photographs, which is usually what patients are asking about.
How many hours a day must I wear them?
They need to be in for the great majority of the day and night, removed only for meals and for drinks other than water. Treatment that falls behind schedule nearly always does so because of wear time, not because of the plan.
Do aligners hurt?
There is usually mild pressure or tenderness for a day or two after changing to a new tray, which is the teeth moving. It settles quickly and is generally described as easier than the adjustment appointments that come with fixed braces.
Can I get aligners if I have had braces before?
Yes. Relapse after previous orthodontic treatment is one of the cases aligners handle particularly well, because the movements required are usually small.
Will I need a retainer afterwards?
Yes, and this is not optional. Teeth drift throughout life regardless of how they were straightened. A fixed or removable retainer is what protects the result you paid for.
