Treatment plans are valid for three (3) months and are only an estimate of costs. If you are not sure of anything the dentist has said please raise it with the dentist and staff. We are here to help!
If you decide to put off treatment then the treatment plan may become invalid as conditions will change over time. A new assessment will therefore need to be done incurring further charges.
If there are problems with timing or costs of treatment then discuss it with the dentist. Sometimes (not always) a compromise treatment may be available to gain some time before the recommended treatment needs to be carried out.
