F.A.Q'S

Got Questions? We’ve Got Answers.

Clear aligners are a series of custom-made, transparent trays designed to gently shift your teeth into their ideal position over time. After a detailed assessment (scan or impression), a treatment plan is created showing how your teeth will gradually move and what your smile will look like at the end.

Treatment length depends entirely on the complexity of your case and how consistently you follow the plan. Many patients complete treatment in 4–12 months, while simpler cases might finish in 2–3 months, and more complex cases take longer.

For optimal results, aligners should be worn 20–22 hours per day, only removing them for eating, drinking (anything other than water), brushing and flossing. Failure to wear them as prescribed can delay your progress.

Cost varies according to complexity of treatment, number of aligners required, and whether other dental/orthodontic services are needed. Many clinics offer payment plans, financing or phased approaches. Make sure your quote includes the full treatment (scans/impressions, aligners, attachments if needed, check-ups, retainers).

Yes — patients with untreated gum disease, poor oral hygiene, significant tooth decay, or severe skeletal discrepancies may not be suitable without preliminary dental/orthodontic work. A full assessment is essential to determine suitability.
