If you are considering Invisalign or other clear aligners, understanding how treatment works can help you compare your options and know what to expect before an orthodontic assessment.
Invisalign clear aligners are removable orthodontic appliances that may be used to gradually move teeth towards planned positions. They can be considered for selected alignment and bite concerns, depending on factors such as tooth position, oral health, treatment complexity and individual clinical findings.
This guide explains how Invisalign clear aligners work, who may be suitable, what treatment can involve, how aligners compare with fixed braces and why retention is important after active orthodontic treatment.

What Is Invisalign and How Does It Work?
Invisalign uses a series of removable clear aligners that are made to guide teeth through a planned sequence of movements.
Each set of aligners is worn according to the treatment plan before progressing to the next stage. The exact schedule and recommended daily wear time depend on the individual treatment instructions provided by your dentist.
Because the aligners are removable, they can be taken out for eating, brushing and cleaning between the teeth. However, consistent wear is important for treatment to progress as planned.
Invisalign is not suitable for every orthodontic concern. An assessment is needed to determine whether clear aligners, fixed braces or another orthodontic approach may be more appropriate.
What Orthodontic Concerns Can Clear Aligners Help Address?
Depending on the individual assessment, clear aligners may be considered for concerns such as:
- Crowded or overlapping teeth
- Crooked or rotated teeth
- Unwanted spaces between teeth
- Certain overbites
- Certain underbites
- Some crossbites
- Other selected tooth alignment concerns
The type and complexity of tooth movement required are important when deciding whether Invisalign may be suitable. Some orthodontic concerns may be more appropriately managed with fixed braces or another treatment approach.
What Happens During an Invisalign Assessment?
An orthodontic assessment helps determine whether clear aligners are clinically appropriate before treatment begins.
Depending on the individual case, the assessment may include:
- Examination of the teeth and bite
- Assessment of gum and dental health
- Discussion of your orthodontic concerns and treatment goals
- Digital scanning
- Clinical photographs where appropriate
- X-rays when clinically indicated
- Discussion of alternative orthodontic options
At Dr Raymond Platon & Associates, treatment recommendations are based on individual findings rather than assuming that clear aligners are suitable for every patient.
What Does Invisalign Treatment Involve?
The exact treatment process varies between patients, but Invisalign treatment may involve the following stages:
- Assessment: Your teeth, bite and oral health are examined.
- Digital records: Digital scans, photographs or X-rays may be used when clinically appropriate.
- Treatment planning: The proposed tooth movements, expected treatment time, possible risks, alternatives and retention requirements are discussed.
- Aligner wear: A sequence of clear aligners is worn according to the individual treatment plan.
- Review appointments: Progress is monitored and additional scans or changes to the plan may be recommended where clinically appropriate.
- Retention: Retainers are generally recommended after active treatment to help maintain tooth position.
Treatment time varies according to the type and complexity of tooth movement required, the bite, oral health, individual response to treatment and how consistently the aligners are worn.
What Are the Potential Advantages of Clear Aligners?
Clear aligners have several practical features that some patients may prefer. These can include:
- A clear appearance while being worn
- The ability to remove the aligners for eating
- The ability to remove them for brushing and interdental cleaning
- No fixed brackets or orthodontic wires
- Digital treatment planning
These features do not mean Invisalign is automatically the best option for every patient. Treatment suitability depends on the orthodontic concern, clinical findings and the type of movement required.
Who May Be Suitable for Invisalign?
Clear aligners may be considered for teenagers and adults with suitable orthodontic concerns who are able to follow the recommended wear schedule.
Factors considered during assessment may include:
- Tooth position and alignment
- The type of bite concern
- The complexity of movement required
- Dental and gum health
- Ability to wear the aligners as instructed
- Individual treatment goals and preferences
An orthodontic assessment is needed to determine whether Invisalign, fixed braces or another approach may be suitable.
Invisalign or Braces: Which Is Better?
There is no single orthodontic treatment that is best for everyone.
Both clear aligners and fixed braces can be effective in suitable cases, but they work differently and have different practical considerations.
Clear aligners are removable and depend on consistent wear. Fixed braces remain attached to the teeth throughout active treatment and can be used for a broad range of orthodontic movements.
The most appropriate option depends on factors such as tooth position, bite, treatment complexity, oral health, age, lifestyle and the patient’s ability to follow treatment instructions.

How Do You Care for Invisalign Aligners?
Good oral hygiene and appropriate aligner care are important throughout treatment.
General care may include:
- Removing aligners before eating unless advised otherwise
- Cleaning the aligners regularly according to the instructions provided
- Avoiding very hot water that may affect the aligner material
- Brushing and cleaning between the teeth before replacing the aligners
- Keeping aligners in their case when they are not being worn
- Attending scheduled orthodontic review appointments
Your dental team can provide individual advice about aligner cleaning and oral hygiene based on your treatment and oral health.
Why Are Retainers Important After Invisalign?
Teeth can move after active orthodontic treatment has finished. Retainers are therefore generally recommended after clear aligner treatment to help maintain tooth position.
The type of retainer and recommended wear schedule depend on the individual treatment plan. Retention requirements may also change over time.

Frequently Asked Questions About Invisalign
Is Invisalign completely invisible?
Invisalign aligners are made from clear material and are designed to be less noticeable than fixed metal braces. However, they are not completely invisible and their appearance can vary depending on the individual treatment setup.
How long does Invisalign treatment take?
Treatment time varies according to the type and complexity of tooth movement required, the bite, treatment goals, individual response and how consistently the aligners are worn. Your expected treatment time will be discussed after assessment and may change as treatment progresses.
Can I eat while wearing Invisalign aligners?
Aligners are generally removed for eating and for drinks other than water. You should follow the instructions provided for your individual treatment.
Does Invisalign treatment hurt?
Some people experience pressure, tenderness or temporary discomfort when beginning treatment or changing to a new set of aligners. The intensity and duration vary between patients.
How many hours a day do I need to wear Invisalign?
Clear aligners generally need to be worn consistently each day for treatment to progress as planned. Your dentist will provide specific instructions about recommended wear time for your treatment.
Can adults have Invisalign treatment?
Yes. Adults may be suitable for Invisalign depending on their oral health, tooth position, bite and the type of orthodontic movement required. Age alone does not determine whether clear aligner treatment is appropriate.
