When a crown or appliance is on the way, the dentist first needs an accurate copy of your teeth. Find out how an optical scan can provide that record in Milton, when it suits the work, and what the visit is likely to involve.
A crown, bridge, night guard or similar piece is made to fit one particular mouth. Before anyone can design it, the team needs a faithful record of the teeth involved, the teeth beside them and the way your jaws close. That record is called an impression. A digital impression collects it with a small optical scanner that builds a three-dimensional surface model on a screen.
So the scan is a measuring step. It does not treat decay, strengthen a tooth or settle whether a restoration is needed; those decisions come from the examination. For suitable cases it can stand in for a tray of soft material, but the area involved, the planned work and the level of detail required all shape which method is chosen.
Ask how the record would be taken for your own treatment and which arrangements are available. Mention a strong gag reflex, a jaw that tires or opens only partway, or a past impression that felt unpleasant. Our team can talk through suitability and the steps involved, without assuming one method is right for every person or every procedure.
An impression is taken because a specific piece of dental work depends on it. Before recording starts, it helps to know which teeth will be captured and what the finished file is meant to support.
A prepared tooth, its neighbours and your bite may all need recording before a crown or other restoration can be designed. Certain appliances rely on an accurate model too. A scan requested without a treatment purpose adds little, so start by asking what your case actually requires.
Some people find a tray of impression material difficult, whether from gagging, the taste or the sense of fullness. Describe what bothered you last time. Scanning may be worth discussing where it suits the work, although a device still has to reach the teeth and comfort cannot be promised.
A new filling, a shifted tooth or a revised treatment plan can make an older impression unreliable. Let the team know what is different. An existing file is reused only when it still holds the information the current work needs.
A digital impression shows the outer shape of teeth and gums. It is not an X-ray or CBCT image, and it cannot take the place of imaging needed to look at roots, bone or anything else below the surface.
Because the model appears while it is being captured, gaps or blurred areas can often be noticed before you leave the chair. Those sections may be scanned again, or recorded another way, before the file is accepted for the clinical and laboratory steps that follow. What matters in the end is a usable record of the required surfaces.
Skipping a full tray of material can make the visit feel easier for some people, though not for everyone, and the length of scanning differs from case to case. Talk beforehand about breaks, how wide you can open and how you would like to be positioned, so the appointment can be shaped around you.
Patient information: UCLH — digital impressions in dental care
Where the system allows it, the team can walk you through the model and show what is being captured. That can explain why nearby teeth or the opposite jaw are included. The model supports planning; it is not a diagnosis in itself.
A suitable digital record may be passed through the proper professional channels to help design or make your dental work. Ask what happens next and who handles it. Capturing the scan does not set the date your work will be ready.
The record has to include the details the planned restoration or appliance depends on. An area may need another pass, or a different recording method, if something is missing. That review is part of getting an impression worth using.
Each visit is shaped by the treatment it supports. Check ahead whether the appointment covers records alone or also includes tooth preparation, a temporary restoration or other care.
The dentist explains why an impression is required and whether scanning is suitable and available for your case. Ask about limits, alternatives and any separate fees. Raise gagging, limited opening or positioning needs before anything begins.
The scanner needs a clear, accessible view of the surfaces involved. That can mean drying the area or gently managing nearby gum tissue, depending on the procedure. When a tooth has been shaped for a crown, its edges must be recorded in careful detail.
A handheld wand is moved slowly around the relevant teeth while the model builds. The opposing teeth and the way your bite closes may be recorded as well. Follow the positioning cues, and use your agreed signal whenever you need a break.
The team reviews whether the information is good enough for its intended use. Extra scanning, or another impression method, may be needed. Before leaving, confirm your next visit, any temporary care instructions and when the finished work will be checked for fit.
Scanning on its own usually involves no recovery time. Freezing, tooth preparation, a temporary restoration or other care done at the same appointment may come with separate advice.
If a temporary crown or similar piece is placed, follow the dentist’s guidance on chewing and cleaning around it. Call the clinic if it comes loose, cracks or feels uncomfortable. A finished scan does not make a damaged temporary something to ignore.
Let the team know if a tooth chips, a filling is replaced somewhere else or your bite feels different after the scan. The record may need another look. New pain or swelling deserves an assessment rather than being accepted as part of the wait.
A new restoration or appliance still needs to be checked in person. Ask about fit, bite, comfort, cleaning and any adjustments. Digital design does not remove the need for that review, or for follow-up if something feels off later.
Bring questions about the planned work, the method that suits your case and what follows the scan. Good answers tie the technology to a clear clinical reason.
Reach out to our Bronte Street practice to talk through your planned restoration or appliance and any worries about impressions. We can outline which records may be needed and confirm what can be arranged for your care. Questions about comfort, timing and the next step are always welcome.
Suitability and availability depend on your treatment and should be confirmed. Scanner images on this page are illustrative and do not show the clinic’s own equipment.
