Common Patient Questions

Everything you need to know before your visit

Using the best available technology, in the hands of our qualified and experienced doctors, we ensure that the respective treatments are carried out with utmost care and precision — to ensure lower pain presence during and after recovery from the treatment.

This depends solely on the treatment type, where it can range from a matter of minutes to a couple of hours. Estimated durations for each service can be found on our services page.

Depending on the treatment, the level of discomfort can differ. A simple filling will not hurt at all, while a nerve (root canal) treatment may cause mild discomfort during recovery. A full arch implant — being a serious surgical procedure — may involve more significant pain that lasts for a longer period. Our team will guide you through what to expect and how to manage recovery for your specific treatment.

Utilising our in-house sterilization equipment, all dental instruments and tools are sterilized to the highest medical standards and stored according to proper medical equipment storage guidelines — ensuring zero contamination and fully protecting our patients from any risk of harm.

We continuously keep pace with the latest developments in dental technology in Sri Lanka and internationally. Our commitment is to always offer patients the most advanced care available — ensuring the best possible outcomes and the least discomfort during and after treatment.
