Are Teeth Aligners Safe?

Clear aligners are made from high quality materials making them more durable.

In today’s world, where selfies are a daily norm and social media serves as a canvas for self-expression, the quest for a dazzling smile is more prevalent than ever. 

A straight set of teeth is no longer just a testament to oral health but has become a symbol of confidence and aesthetic appeal.

If you’re seeking a straighter smile without the inconvenience of metal braces, you’re not alone. 

A study by Felice Festa, published in 2022, reviews the most used materials in manufacturing clear aligners and concludes that clear aligner materials showed only a low level of cytotoxicity, and the clinical use could be considered safe.

But are clear aligners truly safe, and are there any hidden risks involved? 

While many people view aligners as a harmless alternative to braces, the reality is that any orthodontic treatment can potentially lead to side effects.

The popularity of teeth aligners has skyrocketed, with individuals choosing this discreet and comfortable method to achieve a perfectly aligned smile. 

However, amidst this surge, a pertinent question remains: Are teeth aligners genuinely safe, or do they harbor hidden risks?

Understanding Aligners

Aligners are generally considered safer than braces.

Clear aligners, popularized by brands like ClearPath, operate on the principle of gradual teeth movement. 

These nearly invisible trays are custom-made for each individual, providing a snug fit that gently pressures the teeth into proper alignment over time.

Clear Aligners vs. Traditional Braces

When compared to traditional braces, aligners offer unique advantages. 

Notably, they provide comfort, with no metal brackets or wires that can irritate cheeks and gums. 

They also offer discretion, working their magic without drawing undue attention. Furthermore, they have minimal lifestyle impact, as they can be removed for eating and oral care, a luxury not afforded by traditional braces.

However, it’s crucial to acknowledge that no orthodontic treatment is entirely risk-free when considering the safety aspect.

A study in 2018 was designed to overview the available evidence-based information regarding the clinical effectiveness of clear aligners, in comparison with fixed orthodontic appliances. The study concluded that clear aligners represent an aesthetic and more comfortable alternative to fixed orthodontic appliances.

The Functionality of Clear Aligners: How Do They Work?

Clear aligners are custom-made plastic trays that fit over your teeth and gradually shift them into the desired position. 

They are removable, transparent, and comfortable, making them a popular choice for adults and teens who want to improve their smile without drawing attention to their treatment.

Unlike traditional braces, which use metal wires and brackets to move your teeth, aligners use gentle pressure and controlled force to guide your teeth into place. 

You wear each set of aligners for about two weeks, then switch to the next set in the series until your treatment is complete. 

Depending on your case, you may need anywhere from 10 to 50 sets of aligners to achieve your desired results.

Aligners vs. Braces: Pros and Cons

Aligners have many advantages over braces, and vice versa. View the table below and find out what’s best suitable for you:

Contrary to popular belief, orthodontic treatments, including aligners, fall on a spectrum of safety rather than residing in an absolute risk-free zone. 

It’s essential to comprehend the potential side effects, categorized by their severity and frequency.

Things to Look Out For Description 
Common Side EffectsAligner users may experience temporary discomfort, lisping, and minor gum irritation. These are generally expected and transient, resolving as the treatment progresses.
Less Common ChallengesMore infrequently, root resorption and bone loss may occur. Excessive tooth movement and allergic reactions to aligner materials are also possibilities.
Rare ComplicationsAlthough rare, nerve damage and temporomandibular joint (TMJ) issues have been reported. It’s vital to recognize these as outliers but not dismiss them entirely.
Individual FactorsPreexisting dental conditions, adherence to treatment instructions, and the oversight of a dental professional contribute significantly to the overall safety of the treatment.
The Safety Spectrum of AlignersWhile aligners are generally safe and effective when used correctly, they are not without risks. 
Like any orthodontic treatment, aligners can cause some complications or adverse reactions that may affect your oral health and quality of life. 

Potential Side Effects of Aligner Use: Categorized by Severity and Frequency

Here are some of the potential side effects of aligner use:

Common Side Effects

These are the most frequent and minor side effects that most aligner users experience at some point during their treatment. 

They usually resolve on their own or with simple remedies and do not pose any serious threat to your health.

Clear Aligner Side Effects Description 
DiscomfortAligners can cause some soreness or pressure on your teeth and gums when you first start wearing them or switch to a new set. This is expected, as it means that your teeth are moving in the right direction. 

You can ease the discomfort by taking over-the-counter painkillers, applying ice packs or warm compresses to your jaw, or chewing on sugar-free gum or aligner chewies.
LispingAligners can affect your speech temporarily, especially at the beginning of your treatment or when you change to a new set. 

You may notice some lisping or slurring of words as your tongue adjusts to the presence of the trays in your mouth. This is usually not a big deal and will go away as you get used to wearing them. 

You can practice speaking aloud or reading aloud to speed up the process.
Gum irritationAligners can sometimes rub against your gums or cheeks and cause some redness or inflammation. This is usually due to improper fitting or trimming of the trays. 

You can prevent this by making sure that your aligners fit snugly and smoothly over your teeth and gums. 

You can also use dental wax or silicone strips to cover any rough edges or corners that may bother you.
Like most orthodontic treatments, clear aligners certainly pose a limited number of drawbacks.

Tips for Successful Aligner Treatment Description

Root Resorption and Aligners

Root resorption may sound daunting, but understanding it is key to alleviating concerns. Let’s delve into how aligners and your roots interact.

Understanding Root Resorption

A Natural Process: Minor root resorption, where the body’s cells break down the root structure of a tooth, is a natural process during teeth movement and usually poses no long-term concerns. It’s a part of the biological response that allows your teeth to shift positions.

Monitoring Risk Factors: Dentists and orthodontists monitor potential root resorptions throughout treatment using regular X-rays and adjust treatment plans as needed. If significant root resorption is detected, they may reduce the force applied to the teeth or extend the time between aligner changes.

Prevention and Monitoring

Supervision is Key: Dentists closely monitor potential resorptions throughout treatment. X-rays and clinical examinations aid in adjustments to reduce pressure or change the direction of movement.

Early Detection: If you notice symptoms like tooth sensitivity, pain, mobility, or discoloration, contact your dentist promptly for assessment and appropriate treatment.

Tooth Movement Complications

While aligners aim for gentle tooth movement, complications can arise. 

Understanding the causes and preventive measures is crucial. Certain guidelines need to be followed to keep tooth movement complications under control. 

Avoiding Complications

Aligner Adherence: Improper aligner use, such as not wearing them enough or wearing them too much, can lead to unwanted tooth movement. Follow your dentist’s instructions diligently.

Regular Checkups: Maintain regular checkups with your dentist throughout treatment. Monitoring progress allows for timely adjustments or corrections to prevent complications.
