Is Your Smile Ready for Invisalign? Essential Pre-Treatment Steps

Invisalign works by applying gentle, controlled pressure to shift teeth into alignment over time. However, when underlying dental problems exist, they can create complications that interfere with how the aligners fit and function.

Addressing dental issues before starting Invisalign helps to:

• Ensure a Proper Fit: Aligners are designed to fit snugly over teeth. If decay, fractures, or missing teeth alter tooth structure, aligners may not fit correctly.
• Prevent Delays in Treatment: Addressing dental work beforehand avoids mid-treatment complications that could prolong the Invisalign process.
• Maintain Oral Health During Treatment: Since aligners cover the teeth for most of the day, untreated dental problems can worsen over time.
• Enhance Long-Term Results: A strong, healthy foundation leads to more predictable and stable alignment results.

What Dental Work May Be Needed Before Invisalign?

Fillings for Cavities

Cavities are one of the most common dental issues that must be addressed before Invisalign treatment. Even small cavities can weaken the tooth structure and compromise the fit of the aligners.

• Why It is Needed: If decay is left untreated, it can spread beneath the aligners, leading to further deterioration and discomfort. Since Invisalign covers the teeth for up to 22 hours a day, it limits the natural flow of saliva, which helps wash away bacteria.
• How It Helps: Getting fillings before Invisalign stabilizes and strengthens the tooth, ensuring the aligners fit properly and that decay does not progress. If a filling is placed after treatment has begun, new aligners may need to be made.

Tooth Extractions for Crowding or Wisdom Teeth

For patients with severe crowding, there may not be enough space for teeth to shift into their ideal positions. Tooth extractions—including premolars or wisdom teeth—may be recommended to allow for proper movement.

• Why It is Needed: Crowded teeth can block proper alignment and cause Invisalign treatment to be less effective. Additionally, wisdom teeth that push against molars may contribute to shifting and misalignment.
• How It Helps: Removing unnecessary teeth creates room for the remaining teeth to move into their correct positions, leading to more efficient and effective results.

Periodontal Treatment for Gum Health

Gum disease, including gingivitis and periodontitis, must be treated before Invisalign. Healthy gums provide the necessary support and stability for tooth movement.

• Why It is Needed: If gum disease is present, it can lead to inflammation, recession, or bone loss, making it difficult for teeth to shift properly. If left untreated, gum disease can also cause teeth to loosen, affecting the success of Invisalign.
• How It Helps: Addressing gum health before Invisalign strengthens the foundation of the teeth, preventing complications such as gum recession or instability. Scaling and root planing (deep cleaning) may be necessary before starting treatment.

Root Canal Treatment for Infected Teeth

A root canal may be needed if a tooth is infected or has deep decay reaching the inner pulp. This procedure removes bacteria while preserving the natural tooth.

• Why It is Needed: An untreated infection can worsen during Invisalign treatment, leading to pain, swelling, or even tooth loss. Since aligners increase warmth and limit airflow in the mouth, bacterial growth may accelerate.
• How It Helps: A root canal eliminates infection and strengthens the tooth, ensuring it can withstand the pressure of aligners without pain or further damage.

Dental Crowns or Bonding for Weakened Teeth

If a tooth has been significantly weakened due to fractures, decay, or previous fillings, it may require a crown or bonding before Invisalign treatment.

• Why It is Needed: Invisalign applies continuous pressure on teeth. Weakened teeth are at risk of further damage during treatment.
• How It Helps: Crowns or bonding reinforce the strength of the tooth, ensuring it can withstand the movement and pressure of Invisalign aligners.

Dental Implants or Bridges for Missing Teeth

For patients with missing teeth, a treatment plan must be carefully considered before Invisalign begins.

• Why It is Needed: Missing teeth create gaps in the bite that can affect how Invisalign moves the surrounding teeth. Additionally, teeth adjacent to gaps may shift improperly if space is not accounted for.
• How It Helps: Depending on the case, Invisalign may be planned before or after dental implants are placed. In some cases, temporary solutions such as space maintainers are used during treatment.

How a Healthy Foundation Ensures Invisalign Success



Proper Fit and Accuracy

Aligners are custom-made based on the shape of your teeth. Any changes to tooth structure due to decay, fractures, or missing teeth may require new scans and aligners, delaying treatment.

Reduces Mid-Treatment Disruptions

If untreated dental issues arise after Invisalign has begun, treatment may need to be paused or adjusted, prolonging the process.

Minimizes Discomfort

Strong, healthy teeth and gums help reduce pain, inflammation, and irritation throughout Invisalign treatment.

Long-Lasting and Predictable Results

A healthy oral foundation ensures that alignment progresses smoothly, leading to stable, long-term results after treatment.

When Should You Schedule a Pre-Treatment Dental Checkup?

It is very important to schedule a Pre-Treatment dental checkup as this allows us to assess your oral health, identify any underlying issues, and determine whether any necessary dental work—such as fillings, extractions, or gum treatments—should be completed beforehand.

Ideally, a pre-treatment checkup should take place several weeks before beginning Invisalign. This ensures that any required procedures are addressed without delaying your treatment timeline. During this visit, we will:

• Perform a full oral health assessment, including X-rays and a digital scan of your teeth.
• Check for cavities, gum disease, or other dental concerns that may interfere with Invisalign.
• Discuss whether fillings, extractions, or restorations are needed before starting treatment.
• Develop a customized Invisalign plan tailored to your specific dental needs.
• By scheduling this checkup early, you give yourself the best chance for a smooth and successful Invisalign experience.
