Before any orthodontic treatment plan is put together, whether that’s Fastbraces or clear aligners, there’s a step that often gets less attention than it deserves: the exam that happens first. It’s easy to assume the process starts with scans and trays, but a lot gets checked before your teeth ever start moving. Understanding what that involves can make the whole process feel less like a black box before your first appointment.

What Gets Assessed Before Treatment Begins

A pre-orthodontic assessment looks well beyond simply confirming that your teeth are crooked or crowded. Your dentist is building a picture of your whole mouth, since moving teeth affects more than the teeth themselves.

• The health of your gums, since orthodontic movement puts extra demand on gum tissue that’s already compromised
• Any existing decay or old dental work that could complicate treatment if left unaddressed
• Your bite, including how your upper and lower teeth meet, not just how straight individual teeth are
• Your jaw joint and general oral health, to rule out anything that treatment planning needs to account for

None of this is about finding reasons to delay treatment. It’s about making sure the plan that gets built is based on an accurate picture of your mouth, not just the position of your teeth.

Why Gum Health Comes First

Gum disease, even in a mild form, changes how safely teeth can be moved. Teeth with weakened gum support respond differently to the pressure aligners or Fastbraces apply, so this is usually one of the first things checked rather than an afterthought. If gum health needs attention, that’s often addressed as part of ongoing preventative dentistry before orthodontic movement starts, rather than running both at once.

Why Your Bite Gets Its Own Attention

Straightening the position of individual teeth is only part of the picture. Your dentist also looks at how your upper and lower teeth meet when you bite down, since orthodontic movement can shift that relationship in ways that aren’t always visible just from looking at tooth alignment on its own. A bite that isn’t accounted for early can lead to unexpected adjustments later in treatment, which is part of why it’s assessed properly at the outset rather than left to work itself out.

Why Decay and Old Fillings Matter Before You Start

Untreated decay or ageing dental work can complicate an orthodontic plan in ways that aren’t always obvious upfront.

• A cavity that isn’t addressed first can worsen once a tray or bracket makes that area harder to clean
• An old filling nearing the end of its life may need replacing before treatment, rather than partway through
• Structural issues with a tooth can affect how reliably it responds to movement
• Any signs of infection or a compromised tooth need to be resolved before movement begins, since orthodontic pressure can make an existing issue worse

Addressing these first isn’t about ticking boxes. It genuinely affects how predictable and comfortable the rest of treatment is likely to be, which is part of why a full exam happens before any aligner or Fastbraces plan is finalised.

Please note that suitability for any orthodontic treatment, and what needs to be addressed beforehand, depends on individual circumstances and requires an in-person assessment. This information is general and isn’t a substitute for advice from your dentist.

How This Differs Slightly Between Fastbraces and Clear Aligners

The core assessment covers the same ground either way, but there are a few things that tend to get extra attention depending on which option is being considered.

Before Fastbraces

Since Fastbraces can involve earlier movement of both the crown and root of a tooth, your dentist pays close attention to root position and bone support during the exam, to confirm the approach is appropriate for your specific teeth.

Before Clear Aligners

For clear aligners, the exam includes the digital scan used to plan the full aligner sequence, so accuracy at this stage matters for how the whole treatment plan is mapped out from the start.

What the Exam Doesn’t Cover

It’s worth being clear about the limits of a pre-orthodontic assessment too. This exam establishes whether your mouth is in a suitable starting position for treatment, not a guarantee of how your teeth will ultimately respond or how long treatment will take. According to the Dental Council of New Zealand, aligner treatment should involve ongoing contact with a registered oral health practitioner throughout, not just at the initial assessment.

• Exact treatment timelines are estimated, not fixed, and can shift depending on how your teeth respond
• Results vary between individuals, even for people with similar starting positions
• Final outcomes depend on consistent wear and follow-through, not just the initial plan

This is also why check-ins continue throughout treatment rather than stopping after the initial assessment. Your dentist uses these visits to confirm things are progressing as expected and to make adjustments if they’re not, rather than relying solely on what was mapped out at the start.

What to Bring or Mention at Your Appointment

A few things are worth raising at this stage, even if they seem unrelated to straightening your teeth.

• Any history of teeth grinding, jaw pain, or clicking in your jaw joint
• Previous orthodontic treatment, including braces or aligners you may have had as a teenager
• Any medications or health conditions that could affect gum healing or bone density
• Whether you’ve noticed any recent shifting in your teeth, even minor, that prompted you to look into treatment now

Mentioning these upfront, rather than partway through treatment, gives your dentist the full picture needed to plan realistically from the start. It also means fewer surprises later, since factors like grinding or a health condition affecting healing can influence how your treatment plan is structured from day one. General information on accessing dental care in New Zealand is available through Health New Zealand if you’re weighing up when to book.

Frequently Asked Questions

Do I Need a Full Exam Even If I Just Want a Quick Opinion on Aligners?

A proper assessment is generally recommended before any treatment recommendation is made, since suitability depends on more than a quick visual check. Your dentist can advise on the appropriate first step for your situation.

Will the Exam Delay How Soon I Can Start Treatment?

It may add a short amount of time upfront if anything needs addressing first, but this generally leads to a smoother treatment overall. Timelines vary between individuals depending on what the exam finds.

What Happens If the Exam Finds an Issue Unrelated to Straightening My Teeth?

Your dentist will discuss it with you and, if needed, address it before orthodontic treatment begins. This is common and doesn’t necessarily mean a major delay, though it depends on the specific issue.

Is the Assessment Different If I’ve Had Braces Before as a Teenager?

Your dentist will still complete a full current assessment, since your mouth may have changed since then. Previous orthodontic history is useful information, but it doesn’t replace an up-to-date exam.

Can I Choose Between Fastbraces and Clear Aligners Before the Exam, or After?

It’s usually clearer to discuss both after the exam, once your dentist has a full picture of your teeth, gums and bite. What’s suitable for your situation can only be confirmed following an in-person assessment.
