Considering Invisalign but not sure what to expect? You’re not alone. Clear aligners have become one of the most popular ways to straighten teeth, but many people still have questions before starting their treatment.

What Exactly Is Invisalign?

Invisalign is an orthodontic treatment that uses a series of custom-made, removable clear aligners to gradually straighten your teeth. Each set of aligners applies gentle pressure to move your teeth closer to the desired position, without the need for metal brackets or wires.

How Long Does Invisalign Treatment Take?

Treatment time varies depending on how complex your case is. Some people see results in as little as six months, while more advanced cases may take 12–18 months.
Aligners are typically changed every 1–2 weeks, with progress monitored during routine dental check-ins.

Is Invisalign Painful?

You may feel mild pressure or tenderness for a few days when you switch to a new set of aligners. This is completely normal, it’s a sign that your teeth are moving. Most patients describe Invisalign discomfort as more manageable compared with traditional braces.

Can I Remove My Aligners to Eat and Drink?

Yes. One of the biggest advantages of Invisalign is that the aligners are removable. You must take them out to eat or drink anything other than water. This means you can continue enjoying all your favourite foods without restrictions, just remember to clean your teeth before putting your aligners back in.

How Many Hours a Day Do I Need to Wear the Aligners?

For the best results, Invisalign should be worn for 20–22 hours per day. Taking them out too often can slow down your progress and lengthen your treatment time.

Will Invisalign Affect How I Speak?

Some people notice a slight lisp during the first few days as they get used to wearing their aligners. This usually goes away quickly as your mouth adjusts.

Are the Aligners Really Invisible?

Invisalign aligners are very discreet. Most people won’t notice you’re wearing them unless they’re standing very close. They’re made from a smooth, transparent material that fits snugly against the teeth.

Can I Drink Coffee or Tea With Invisalign?

It’s best to remove your aligners before drinking hot or coloured beverages. Heat can warp the plastic, and darker drinks may stain the aligners. Water is the only safe drink while wearing them.

Is Invisalign Suitable for Everyone?

Invisalign can treat a wide range of concerns, including:

• Crowding
• Gaps between teeth
• Overbites
• Underbites
• Crossbites
• Mild to moderate crookedness

However, very complex cases may still require traditional orthodontics. A consultation is the best way to find out if Invisalign is right for you.

What Happens During Invisalign Treatment?

A typical Invisalign journey includes the following stages:

Consultation: Your dentist assesses your teeth and discusses your goals.

3D Scan: A digital scan captures an accurate model of your teeth.

Treatment Plan: You’ll see a predicted visual of your smile transformation.

Aligner Fitting: You receive your first set of custom aligners.

Regular Check-Ins: Progress is reviewed, and new aligners are provided.

Retention: After treatment, retainers help maintain your results.

How Much Does Invisalign Cost?

Costs vary depending on the complexity of your treatment, the number of aligners required, and the practice. Your dentist will provide a tailored quote during your consultation, along with any finance options that may be available.

How Do I Keep My Aligners Clean?

Keeping aligners clear and fresh is essential. Here’s how:

• Rinse them with cool water
• Use a soft toothbrush (no toothpaste, to avoid scratching)
• Soak in aligner-cleaning crystals if recommended
• Avoid hot water, as it can distort the aligners

Good oral hygiene helps prevent staining and keeps your mouth healthy throughout treatment.

Can I Switch to Invisalign If I’ve Previously Had Braces?

Yes. Many adults use Invisalign to refine their smile after orthodontics earlier in life, especially if they stopped wearing retainers and experienced relapse.
