Step 04
Get a clearer answer
The accessible findings can support no cavity work, a localised solution, extraction or a later replacement discussion.
A request is not a confirmed appointment.
Submitting the form creates an enquiry for Thermorite to review. The team will contact you to confirm eligibility, discuss access and agree any visit details.
Please do not include financial details, medical information or other sensitive personal data in the free-text field.
