Underbite is a lesser-known form of malocclusion. Find out about the causes of underbites and explore how to fix an underbite with Impress treatment.
Underbites are a form of malocclusion that is often genetic, as genes influence the shape and size of your jaw. Sometimes it is the result of an underdeveloped upper jaw or the result of an oversized lower jaw. It could also be in response to trauma or injury, or thumb sucking and the use of dummies in infancy.
Transparent aligners are an effective and comfortable way to correct an underbite. Perfectly tailored to your teeth, start with a free 3D scan and personalised treatment plan.




Comfortable: they do not have metal wires that can chafe and cause irritation.
Discreet: They are virtually invisible, so they won't alter your appearance during treatment.
Removable: You can remove them for eating, drinking and brushing your teeth, making oral hygiene easier.
Customised: They are made to measure for your teeth, ensuring a perfect fit.
App-tracking: With systems like the Impress app, you can track your progress from home.
Fewer visits to the dentist: Requiring fewer adjustments than traditional braces, they save you time.
Effective in mild and moderate cases: In many cases, they can correct the underbite without the need for more invasive treatments.
Clear treatment plan: with an initial 3D scan to plan the alignment with maximum precision.
During your first appointment, our dentists will fully assess your teeth using a 3D scan, oral examination and X-ray if necessary. You'll immediately hear whether you're suitable for treatment with transparent aligners, how long treatment would last and your options regarding payment.

Based on your scan results, our dentists will create a treatment plan tailored specifically to your teeth and situation. This includes a clear 3D prediction of the final result, so you know exactly what to expect.

Your aligners will be delivered to your home in a convenient Impress kit. Our dentists will monitor your progress through the Impress app and regular checkups, so you can work towards a healthy, straight smile step by step.
