A General Dentist Explains How Teeth Straightening with Invisalign® Works

For those with crooked smiles, teeth straightening using the Invisalign® system is an excellent option for improving the appearance. Invisalign® uses a system of aligners custom-fit to each patient. These trays are comfortable to wear, with no wires or brackets, and are low-profile because they are clear. Being removable, aligners also allow patients better access to tooth surfaces, thereby allowing better cleaning of teeth.

The Invisalign® process

The Invisalign® process begins with a consultation. Not everyone is a candidate for aligners. For those who are, the dentist can provide an overview of the Invisalign® teeth straightening process and what to expect.

1. Scanning teeth to create aligners

Dentists first take photos and X-rays of the patient’s teeth, as well as a digital 3D scan. Using this as a model, each step in the repositioning process is carefully plotted. For each stage, a new aligner is made to bring teeth to the updated position.

2. Fitting and wearing aligners

Once the trays are made, patients return for a fitting. Dentists may place small attachments, much like buttons, to the teeth to help keep the trays in place. These temporary buttons are clear and are not painful to fit. Patients are typically given all the aligners made for their treatment to take home and begin wearing.

3. Making periodic progress checks

After the first few weeks, dentists check the aligners for comfort, fit and effectiveness. Patients are generally advised to place a new tray every few weeks on their own and need to return periodically for the dentist to check on the overall progress.

The length of time wearing aligners depends on the condition of each patient’s teeth. Those with slight misalignments may take as few as six months to complete treatment. For others, it can take several additional months to reach the final stage.

How to care for Invisalign® trays

Aligners are designed to be worn between 20 and 22 hours each day. Patients generally should not remove them while sleeping. Failure to wear them for this length of time can make them less effective and also lengthen the overall treatment time.

What to do

Aligners should be taken out of the mouth for eating and drinking, as hot and cold temperatures can affect the trays. Food may also get caught in aligners if worn while chewing. Patients should brush their teeth after each meal before replacing aligners. The trays should be cleaned nightly with a toothbrush and Invisalign® solution or using lukewarm water and a soft, clear soap that is also unscented.

What not to do

Wearers should not use toothpaste to clean their aligners as it may scratch them. Denture cleaners and mouthwash are additional products that should never be used with aligners. Use a soft-bristle toothbrush and gently brush the trays, being careful not to apply much pressure.

Conclusion

Correcting teeth alignment is easier now thanks to developing technology. The Invisalign® teeth straightening system can help make for a long-lasting and beautiful smile.
