Clear aligners have become one of the most searched orthodontic treatments in Sri Lanka. Patients often have many questions about cost, treatment duration, safety, and suitability before starting their smile journey.
This FAQ page answers the most common questions asked by patients in Sri Lanka regarding clear aligner treatment at Cayo Dental Hospital.
Clear aligner treatment in Sri Lanka typically ranges between LKR 100,000 and LKR 500,000, depending on the complexity of the orthodontic case and the number of aligners required.
Minor corrections may cost less, while more complex bite corrections require longer treatment and therefore higher costs.
Some minor orthodontic corrections such as fixing a single crooked tooth may start around LKR 100,000.
However, treatment cost depends heavily on the number of aligners required and the complexity of the dental condition.
In some cases, yes. Traditional metal braces in Sri Lanka typically cost LKR 120,000–250,000, while clear aligner treatments may range from LKR 100,000–500,000 depending on the case.
However, aligners offer advantages such as invisibility, comfort, and easier oral hygiene.
Prices vary due to several factors including:
Clinics that use advanced digital orthodontic planning may have higher costs due to technology and laboratory expenses.

This is a normal part of orthodontic treatment.
