Risks And Complications of Invisalign: What You Should Know Before Getting Started

Invisalign is one of the popular orthodontic treatments that uses clear, removable aligners to correct dental problems, such as teeth misalignment, crooked teeth, crowded teeth, gaps between teeth, and bite problems. It is an alternative to traditional metal braces to achieve a straighter smile.

While it is generally considered to be safe, there are some risks and complications that you should be aware of before getting started.

What Possible Complications Can Happen with Invisalign?

Like other orthodontic treatments, there are a few potential risks with Invisalign, such as:

• Allergic reactions

Though it rarely happens, a few people may be allergic to the materials used in Invisalign aligners, such as acrylate. It happens when the plastic irritates the gum tissue. Symptoms of an allergic reaction include redness, itching, swelling, and blistering of the skin. 

• Tooth Discomfort

It is common to experience tooth discomfort during the first stages of orthodontic treatments, including Invisalign. This is because your teeth are slowly being moved into the correct position and your aligners put pressure on your teeth. The discomfort should disappear after a few days as your teeth get used to the aligners. However, if the pain persists, your dentist or orthodontist may need to adjust your treatment plan

• Cavities

Cavities are holes in the teeth caused by tooth decay. It is caused by bacteria in plaque which accumulate on the teeth and produce acids that damage the enamel. If you don’t practice good oral hygiene, bacteria-filled plaque can get stuck in the aligners, leading to cavities.

• Tooth decay

Tooth decay is a common complication of Invisalign. It happens when you don’t brush and floss your teeth regularly. As a result, plaque and tartar build-up on your teeth, leading to tooth decay. Symptoms include toothache, bad breath, and sensitivity to hot and cold drinks.

• Gum disease

Gum disease occurs when plaque and tartar accumulate on the teeth and irritate the gum tissue. This usually results from poor oral hygiene or not cleaning your aligners. This can lead to inflammation, redness, and bleeding of the gums. If not managed immediately, it can damage the bone and connective tissues supporting the teeth.

• Mouth sores

This happens when the aligners rub against the gums and cheeks, which usually happens when the aligners don’t fit properly. Mouth sores can lead to irritation and inflammation. Symptoms include redness, swelling, and pain.

Can Invisalign Damage Your Teeth? 

While it’s common to feel discomfort in your teeth when you first wear your aligners, Invisalign will not damage your teeth if you follow your dentist’s instructions. 

How Can You Avoid Complications with Invisalign?

There are many ways to avoid complications associated with Invisalign. These include the following:

• Wear your aligners as instructed by your dentist

You must wear your aligners at least 22 hours per day to achieve favourable results. Wearing them less frequently may delay the treatment.

• Clean your aligners regularly

You must clean your aligners every day to prevent plaque and tartar build-up. Use a soft-bristled toothbrush and clear soap to brush your aligners. Avoid using toothpaste because it can be abrasive to plastic aligners. 

You can also use a denture cleaner to soak your aligners for 10 to 15 minutes. Avoid using hot water to rinse your aligners, as this can damage the plastic.

• Remove your aligners before eating

You must remove your aligners when you eat or drink to prevent damaging your aligners. Doing this will also prevent food particles from getting stuck in the aligners, which can lead to tooth decay and delay your treatment.

• Practice good oral hygiene

A good dental care routine is essential to avoid complications associated with Invisalign. You must brush and floss your teeth at least twice a day and floss once daily, just like you would without aligners.

• Visit your dentist regularly

You should follow your scheduled appointments so your dentist can monitor your progress and check if your treatment is going as planned. This also allows them to catch potential problems early on and prevent them from becoming serious.  

In addition, even in Invisalign treatment, you still need to see your dentist for professional cleanings and checkups every six months.

• Quit smoking or reduce tobacco use

Smoking or using tobacco can cause a number of problems, such as gum disease, staining of the teeth, and bad breath. It can also interfere with healing and increase the risk of infection after dental procedures. These can all lead to delays in your treatment. If you smoke, consider quitting or reducing tobacco use.

• Don’t drink hot water while wearing your aligners

This may not cause complications, but hot water or any hot beverages can alter the shape of your plastic aligners.

Who Should Avoid Invisalign Treatment?

If you have the following condition, you may want to avoid this dental treatment and ask your dentist for other treatment options instead:

• Severe teeth misalignment, bite problems, and gaps between teeth

Invisalign may not be suitable if you have severe teeth misalignment, bite problems, or tooth gaps. This dental procedure is designed to correct these orthodontic issues but not severe conditions as it doesn’t have the strong force needed to address them.

• Missing teeth

You must have all your natural teeth to be eligible for Invisalign treatment, as the clear aligners will attach to your existing teeth. Traditional braces may be suitable for you if you have missing teeth.

• Bleeding disorders

If you have an unmanaged bleeding disorder, Invisalign treatment may not be recommended, as the trays may irritate your gums and cause bleeding. This will only delay your treatment and lengthen the time you need to wear the clear aligners.

• Allergies to polyurethane resins

Invisalign plastic aligners are made of polyurethane resins. If you are allergic to this material, Invisalign may not be a good option for you, and you should ask your dentist about an alternative treatment.

• Pregnant women

Pregnant women can get Invisalign if all scans and X-rays are completed before they conceive. However, if you are already pregnant and plan to get Invisalign, you may want to wait until after you give birth. Note that radiation exposure may not be ideal for developing babies.
