A Comprehensive Guide to Teeth Straightening With Invisalign Aligners

Invisalign aligners are modern orthodontic devices designed to discreetly enhance your oral aesthetics. If you've been thinking about straightening your teeth but aren't keen on the idea of metal braces, Invisalign might be what you're looking for.

There are a few simple practices to follow to ensure your clear aligners remain invisible while gradually shifting your teeth into proper alignment. Here's everything you need to know about Invisalign aligners.

What Are Invisalign Aligners?

Invisalign is an orthodontic treatment that straightens your teeth using a series of clear, removable plastic trays called aligners. Unlike traditional metal braces, these trays are virtually invisible when worn, making them a popular choice for both teenagers and adults.

Each set of aligners is custom-made for your mouth and worn in a specific sequence. Every few weeks, you move on to the next set in the series, and each new tray gradually nudges your teeth a little closer to their ideal position. The trays are made from a smooth, BPA-free plastic material called SmartTrack, which is designed for a comfortable, snug fit.

Who Is Invisalign For?

One of the benefits about Invisalign is that it works for a broad range of ages, including children, teenagers, and adults alike. There is generally no upper age limit, provided your gums and supporting bone structures are healthy. You may be a good candidate if you have: 

• Tooth gaps
• Minor to moderate bite issues
• Moderate crowding issues
• Relapse after your previous braces.

Invisalign is generally not recommended for people with active gum (periodontal) disease, as the health of your gums and bone needs to be stable before any orthodontic treatment begins. 

How Does the Invisalign Aligners Work?

Invisalign trays help you get a healthier, straighter smile while supporting your facial aesthetics during the treatment. At Dental Designs Singapore, here's what you can expect:

Initial Consultation

During this consultation, our dentists will examine your teeth, discuss smile goals, eligibility, and treatment procedure. This is also a good time to ask any questions you may have and find out whether Invisalign is suitable for your specific situation. 

Personalised Treatment Planning

Using 3D scans and intra-oral photographs of your dental arch, we design a treatment plan that suits your needs. Modern digital imaging helps enhance the effectiveness of the procedure.

Treatment Simulation

The ClinCheck procedure is done next. This is where the software maps out the entire movement of your teeth from start to finish, allowing you to see a virtual preview of your projected results before treatment even begins. 

Custom Aligners

Your aligners are then manufactured based on your treatment plan. Once ready, your dentist will check that the trays fit comfortably, and make any necessary adjustments. You'll be advised to wear your aligners for 20 to 22 hours a day, removing them only to eat, drink anything other than plain water, brush, and floss. 

Regular Review Appointments

You'll have periodic check-ins with your dentist, typically every 6 to 8 weeks, to monitor your progress and ensure your teeth are moving as planned.

Retainers after Treatment

Once you've completed your final set of aligners, your dentist will recommend wearing a retainer. This is an important step because without a retainer, teeth have a natural tendency to drift back towards their original position over time. Some patients may also need minor cosmetic refinements such as tooth reshaping to perfect the final result.  

How To Care For Your Invisalign Aligners

Taking good care of your aligners isn't just about keeping them looking nice, it directly affects the success of your treatment and your overall oral health.

• Plaque and bacteria can build up on poorly maintained aligners, increasing the risk of tooth decay and gum problems.

• Discoloured or cloudy trays can become quite noticeable, defeating the purpose of choosing a "clear" option in the first place.

• Warped or cracked aligners won't fit properly, which can disrupt the carefully planned movement of your teeth and potentially add to your treatment costs.

How To Clean And Maintain Your Invisalign Aligners

You may be cleaning your Invisalign aligners daily, but are you doing it right? Check the below points to learn about the proper cleaning methods.

Remove and Clean

Every time you remove your Invisalign aligners, it is advisable to clean them using lukewarm water. It helps to remove any dirt and minimise plaque buildup so that you feel fresh when reusing.

Use Soft Toothbrush and Soap

Brush gently with a soft-bristled toothbrush and mild, clear antibacterial soap. This removes food debris and bacteria without damaging the surface. Avoid coloured soaps, as they can stain the plastic. 

Invisalign Cleaning Crystals

Use Invisalign cleaning crystals (or other aligner-specific cleaning tablets) for a deeper clean. These are designed to tackle stains and odour safely and effectively. 

Store in Protected Case

Whenever you are not wearing your invisible braces, it is recommended to put them inside their ventilated case. This protects them from getting lost or being accidentally damaged. Also, it is necessary to keep the case clean.

Maintain Oral Hygiene

Brush and floss your teeth before reinserting your aligners. Trapping food particles or bacteria under your trays can lead to bad breath and increase the risk of cavities.

What You Should NOT Be Doing

When it comes to cleaning your Invisalign aligners, adopting wrong methods can affect the treatment progress. These are some guidelines you should follow.

Do Not Clean With Hot Water

Cleaning with hot water is not recommended as it can warp the Invisalign plastic trays. As a result, the fit can be affected along with the treatment progress. 

Avoid Toothpaste

Despite seeming like a logical choice, most toothpastes contain abrasive particles that can create micro-scratches on the surface of your aligners, making them look dull and more visible. 

No Harsh Chemicals

While your Invisalign requires deep cleaning, it is crucial to ensure you are not using any harsh chemicals such as bleach, or any other alcohol-based cleaners. This practice may permanently distort your braces and affect the treatment process.

What Are The Benefits of Invisalign Aligners?

Many people choose Invisalign treatment due to certain reasons, which include:

• The aligners are translucent which allows them to discreetly shift your teeth to the desired position. For people, who do not prefer traditional braces because they are visible, can opt for Invisalign to achieve their dream smile.

• As these are removable, it can be removed before eating. This not only allows you to maintain the Invisalign aligners properly, but also enjoy your meals without any inconvenience.

• Unlike traditional braces, there’s no metal brackets or wires in the Invisalign aligners. The plastic trays are comfortable and ideal for full-time wear. This reduces the frequent visits to the dentist’s office for adjustments.

Frequently Asked Questions About Invisalign Aligners

Q) How long does the treatment take?

The treatment time depends on your specific requirements and oral condition. Invisalign for adults may take longer compared to that for children or teens. At Dental Designs, our dentists will use 3D scans and digital x-rays to have a closer look at your teeth for appropriate treatment planning.

Q) What should I do if my aligner cracks?

Remove it straight away, as sharp edges can irritate or injure the soft tissue inside your mouth. Contact your dentist promptly and they may advise you to move to the next tray in your series or arrange for a replacement. 

Q) Can I remove the aligners while eating or drinking?

You should remove your aligners before eating any food and before drinking anything other than plain water. Food can get trapped underneath and stain the trays, and some drinks (especially hot ones) can damage them.

Q) How much do Invisalign aligners cost?

The cost broadly depends on the complexity of your case and the total aligner count. More complex cases requiring more aligners will naturally cost more. It is worth requesting a detailed breakdown during your consultation. 

Q) Will I need to wear retainers after Invisalign?

Yes. Retainers are a standard and necessary part of any orthodontic treatment, Invisalign included. Your dentist will advise you on how often to wear them.
