Invisalign and other types of clear aligners are widely praised for their numerous benefits. If you are considering undergoing this treatment, you have plenty of reasons to be excited. However, it is worth your time to ask relevant questions, such as, “How do clear aligners work? and “What are the advantages and disadvantages of clear aligners?” Understanding the potential risks along with the benefits can help you make an informed decision about your next steps. In this blog post, you will learn about some of the most common issues associated with clear aligner treatment.

Discomfort

You may have heard that clear aligners are more comfortable than traditional braces, and that is true. However, they are not completely free from discomfort. As your teeth move into their desired positions, you may experience soreness or pressure, particularly when you first start using a new set of aligners. This discomfort is usually temporary and can be managed with over-the-counter pain medications.

Allergic Reactions

Clear aligners are made of a smooth plastic material, which most patients tolerate without any problems whatsoever. Occasionally, though, allergic reactions can occur. Symptoms may include itching, swelling, or a rash. If you suspect you have an allergy to your aligners, consult your dentist immediately. You may need to switch to a different type of orthodontic treatment.

Cavities and Gum Disease

Oral hygiene is always of utmost importance, but it is especially critical during orthodontic treatment. If you do not keep up with brushing and flossing your teeth, food particles and plaque can become trapped between the aligners and your teeth, leading to decay, gum problems, bad breath, and other issues. If you would like personalized advice on how to maintain a clean and fresh smile during clear aligner treatment, talk to your dental care team.

TMJ Disorder Flare-Ups

If you have temporomandibular joint disorder (TMD), clear aligners might exacerbate your condition. These episodes can result in jaw pain, headaches, or reduced jaw mobility. Discuss any pre-existing TMJ issues with your dentist before starting treatment. Most patients with TMD can keep symptoms under control with pain management measures and continued professional guidance. There is even a chance that clear aligners can correct the underlying cause of TMD and lead to long-term relief!

Speech Challenges

Adjusting to clear aligners might temporarily affect your speech. You might notice a slight lisp or that you need to speak more slowly than usual. Fortunately, most patients find that their speech returns to normal after a few days or few weeks. If you experience ongoing speech challenges, consult with your dentist.

The Benefits of Clear Aligners Outweigh the Risks

Just like any other treatment, clear aligners are not totally risk-free. However, for most patients, their benefits outweigh any downsides. To learn more about this treatment and to find out if it is right for you, talk to a qualified dental team.
