Does Invisalign Help with Teeth Grinding? 6 Key Facts

Invisalign is a cutting-edge dental treatment that employs clear plastic aligners to straighten teeth. Unlike traditional metal braces, Invisalign aligners are nearly invisible. They can be detached for eating and cleaning, making them a preferred choice for many seeking a discreet method to achieve a beautiful smile.

Bruxism or commonly known as teeth grinding, is a condition where one grinds or clenches their teeth, often unconsciously, whether during sleep or while awake. This habit can lead to several dental problems, such as worn-down teeth, jaw pain, and temporomandibular joint (TMJ) disorders. Managing bruxism is crucial as it can cause significant discomfort and lead to severe damage to the teeth and jaw over time.

Recently, there has been growing interest in using Invisalign to treat bruxism. Invisalign aligners can act as a barrier to avoid direct contact, thus mitigating the damage caused by grinding. Moreover, Invisalign treatment can help realign teeth and correct bite issues, which are often underlying causes of bruxism. By slowly moving teeth into their positions, Invisalign can help distribute biting surfaces more evenly, reducing the uneven pressure that exacerbates teeth grinding.

What is Invisalign?

Invisalign is a modern dental treatment that straightens teeth using clear plastic aligners. These aligners are custom-made, removable, and virtually invisible, making them a popular choice for those seeking a discreet way to improve their smile.

It corrects misaligned teeth and bite issues, leading to straighter teeth and better oral health. The clear aligners are removable, making it convenient to maintain good dental hygiene compared to traditional braces. Patients can eat, drink, brush, and floss without the restrictions posed by metal brackets and wires.

Unlike traditional braces, Invisalign aligners are made of smooth, clear plastic and are custom-fitted to the patient’s teeth. The aligners gradually shift teeth into their correct positions, giving a more comfortable and aesthetically pleasing alternative to metal braces.

What is Bruxism?

Bruxism or teeth grinding, is where individuals grind or clench their teeth, often unconsciously. This leads to various dental issues, including worn-down teeth, jaw pain, and TMJ disorders. Bruxism occurs during the day (awake bruxism) or at night (sleep bruxism). Both types of bruxism can cause significant discomfort and long-term damage to the teeth and jaw if left untreated.

Awake bruxism typically involves clenching the teeth and is often associated with stress or anxiety. People may grind their teeth during periods of concentration or tension, which can lead to jaw pain and headaches. Sleep bruxism, on one hand, occurs during sleep and is often harder to control. It can result in more severe wear on the teeth and is usually detected by a bed partner or through symptoms such as morning jaw pain or a sore jaw. Managing teeth grinding effectively often requires a comprehensive treatment plan, which may include using night guards, undergoing treatment like Invisalign, or addressing underlying stress factors.

Causes and Symptoms of Teeth Grinding

Bruxism can be caused by various factors. One of the most common causes is stress and anxiety. Many people grind their teeth as a physical response to emotional stress or tension. This is often seen in both awake bruxism, where individuals grind their teeth during periods of concentration or nervousness, and sleep bruxism, which occurs unconsciously during sleep.

Another significant cause of bruxism is misaligned teeth or a misaligned bite. When the teeth do not fit correctly together, it can create uneven pressure across the biting surfaces. This misalignment can lead to chronic bruxism as the jaw tries to find a more comfortable position. Crowding or crooked teeth, often contribute to this problem, making treatment with solutions like Invisalign suitable for addressing the root cause.

The symptoms of bruxism can vary in severity and impact. One of the most noticeable symptoms is the sound of teeth grinding or clenching, which is often loud enough to be heard by a sleeping partner. This grinding can cause significant wear on the teeth, which leads to tooth sensitivity and even fractures over time.

Jaw pain is another common symptom of bruxism. The excessive force used during teeth grinding can strain the joints and muscles of the jaw, particularly the temporomandibular joint (TMJ). This can result in jaw soreness, headaches, and discomfort in the neck and shoulders. Persistent bruxism can lead to TMJ disorders, which require comprehensive treatment.

Managing Teeth Grinding with Invisalign

Invisalign treatment can help manage bruxism, especially in cases where misaligned teeth or a misaligned bite are contributing factors. Invisalign aligners act as a barrier between the upper and lower teeth, minimising the risk of damage from grinding.

They also work to gradually shift the teeth into their ideal positions, which can alleviate the uneven pressure that exacerbates bruxism. For those with mild to moderate bruxism, Invisalign clear aligners offer the dual benefit of protecting the teeth while providing treatment for a straighter smile. However, for severe bruxism cases, additional interventions like night guards may be necessary to manage the condition entirely. Consulting with a dentist can help you choose the most suitable treatment plan for each individual.

How Invisalign Can Help with Bruxism

Invisalign treatment can be beneficial for individuals with bruxism, especially those with misaligned teeth or a misaligned bite, which can exacerbate the condition. Invisalign clear aligners act as a protective barrier, helping to distribute the biting surfaces more evenly and reducing the excessive force caused by teeth grinding. This can alleviate jaw pain and prevent severe damage to the teeth. Additionally, as the aligners gradually move the teeth into their ideal positions, they can help resolve bite issues, leading to straighter teeth and improved oral health.

Patients undergoing the Invisalign journey for bruxism management may find that the aligners not only help protect their teeth but also contribute to a beautiful smile by addressing misalignment. While Invisalign is right for mild to moderate cases of bruxism, severe bruxism cases might still require additional protective measures, such as night guards.

Can Invisalign Cause Discomfort for Bruxism Patients?

Clear aligners are designed to be comfortable and smooth, but some discomfort is normal, especially when starting a new set of aligners. For bruxism patients, Invisalign can actually help alleviate discomfort associated with teeth grinding by providing a barrier between the upper and lower teeth. However, it’s important to note that while the aligners may reduce some symptoms of bruxism, they might not eliminate all discomfort related to the condition, mainly if the underlying causes are not addressed.

Will Invisalign Affect Speech if I Have Bruxism?

Invisalign aligners can initially affect speech as your mouth adjusts to wearing them. You might experience a slight lisp or difficulty pronouncing certain words at first. This adjustment period is usually temporary, and most patients adapt within a few days to a couple of weeks. For bruxism patients, the benefits of protecting teeth and reducing grinding-related damage generally outweigh the temporary speech adjustments.

Can Invisalign Cause Bruxism?

Invisalign does not cause bruxism. Bruxism typically results from factors like stress, anxiety, misaligned teeth, or bite issues. In fact, Invisalign can help mitigate some of these factors by correcting misalignment and bite problems, potentially reducing the occurrence of teeth grinding. If a patient starts experiencing bruxism symptoms while using Invisalign, it is essential to consult with a dentist to explore other possible causes and appropriate treatments.

Benefits of Using Invisalign for Bruxism

Here are some benefits of using Invisalign to manage teeth grinding:

Aesthetic Appeal and Comfort

Invisalign aligners offer significant aesthetic appeal and comfort compared to traditional metal braces. Made from clear plastic, Invisalign are nearly invisible, allowing patients to straighten their teeth discreetly. This makes them an attractive option for young adults and professionals who may feel awkward about wearing metal brackets. Additionally, the smooth, custom-fit design of Invisalign aligners ensures a comfortable fit, reducing the likelihood of irritation to the gums and cheeks that is often experienced with traditional braces.

Oral Health Benefits

One critical oral health benefit of Invisalign is the ease of maintaining good dental hygiene. Unlike traditional braces, which can trap food debris and plaque around the metal brackets and wires, Invisalign aligners are removable. This lets patients to brush and floss their teeth regularly, reducing the risk of gum disease and cavities. Improved dental hygiene contributes to overall health, preventing dental issues that can exacerbate bruxism.

Improved Teeth Alignment

Invisalign treatment helps improve teeth alignment, which can significantly reduce teeth grinding. Misaligned teeth and bite issues often contribute to bruxism by causing uneven pressure across the biting surfaces. By slowly moving the teeth into their optimal positions, Invisalign can help alleviate these issues, reducing the tendency to grind teeth and thereby preventing jaw pain and damage to the TMJ.

Protective Layer

Invisalign clear aligners act as a protective layer between the upper teeth and lower teeth, avoiding the wear and tear because of grinding your teeth. This protective layer can prevent severe damage to the teeth, such as chipping, cracking, and excessive wear, which are common in chronic bruxism cases. By wearing Invisalign aligners, patients can protect their teeth from the excessive force exerted during grinding.

Increased Awareness

Wearing Invisalign aligners can also increase awareness of clenching and grinding behaviours. The presence of the aligners in the mouth can make patients more conscious of their jaw movements, helping them identify and reduce instances of clenching or teeth grinding. This increased awareness can be a valuable part of managing bruxism and reducing its impact on oral health.

Comprehensive Management of Bruxism

Invisalign provides a comprehensive approach to managing bruxism, addressing both the symptoms and underlying causes. By giving a combination of aesthetic appeal, comfort, improved oral health, and protective benefits, Invisalign aligners are a suitable option for many patients. Whether dealing with mild bruxism or looking for a dual solution to both straighten teeth and manage grinding, Invisalign presents a modern, effective treatment option.

Limitations of Invisalign for Bruxism

Below are some limitations as you wear Invisalign to manage tooth grinding:

Not a Guaranteed Cure for Bruxism

Invisalign treatment is not a guaranteed cure for bruxism. While Invisalign aligners can help mitigate some symptoms of teeth grinding by improving teeth alignment and providing a protective barrier, they do not address all the underlying causes of bruxism, such as stress or anxiety. As a result, patients may still experience bruxism despite undergoing Invisalign treatment. Patients need to incorporate additional strategies, such as stress management techniques or the use of night guards, to address the condition entirely.

May Not Be Suitable for Severe Bruxism Cases

Invisalign may not be suitable for severe bruxism. Patients with chronic or severe bruxism may require more robust solutions, such as custom-fitted night guards that offer a higher level of protection against the excessive force exerted during teeth grinding. In severe cases, continuous grinding and clenching can cause significant wear and tear on the aligners, reducing their effectiveness and lifespan. Additionally, severe bruxism can lead to complex dental issues that might require alternative dental appliances or treatments beyond what Invisalign can provide.

Additional Considerations

Effectiveness with Severe Misalignments

Invisalign is effective for many misalignment issues; it can treat complex cases such as overbite, underbite, open bite, crowded teeth, and the like. It is a much better option than other treatments as you can discreetly. Patients should ask their dentist to know the most appropriate treatment for their specific needs.

Compliance and Consistent Use

The effectiveness of Invisalign for both teeth alignment and bruxism management heavily depends on patient compliance. Patients need to wear their aligners consistently, for 20 to 22 hours a day, to achieve optimal results. Inconsistent use can prolong treatment times and reduce the effectiveness of the aligners in protecting the teeth from grinding.

Managing Jaw Pain and TMJ Disorders

Invisalign aligners can help with jaw pain related to misaligned teeth and bruxism, but they may not fully resolve temporomandibular joint (TMJ) disorders. TMJ disorders often require a multi-faceted approach to treatment, including physical therapy, pain management techniques, and, in some cases, surgical interventions. Invisalign can be part of the overall management strategy, but additional treatments may be necessary for comprehensive relief.

Can I Get Invisalign If I Grind My Teeth?

Here are some factors to consider for Invisalign and Bruxism suitability:

  1. Severity of Bruxism: The severity of bruxism is a critical factor in determining whether Invisalign is a suitable treatment option. For individuals with mild to moderate bruxism, Invisalign aligners can help manage the condition by providing a layer between the upper teeth and lower teeth, reducing wear and tear from grinding. However, in severe cases of bruxism, where the grinding is intense and persistent, Invisalign alone may not provide adequate protection.
  2. Cause of Bruxism: Understanding the underlying cause of bruxism is essential when considering Invisalign as a treatment option. Various factors, including stress, anxiety, sleep disorders, or misaligned teeth, can trigger bruxism. If the primary cause is related to dental alignment issues, Invisalign can help alleviate the uneven pressure on the teeth that often leads to grinding. However, if the cause of bruxism is primarily due to stress or anxiety, additional interventions, such as stress management techniques, therapy, or medication, may be required to address the root cause effectively.
  3. Dentist Recommendation: Consulting with a dentist is crucial in determining the suitability of Invisalign for managing bruxism. A dental professional can evaluate the specific details of your condition, including the severity and cause of bruxism, and recommend the right solution.They will conduct a dental examination, possibly including X-rays and digital scans, to assess the your teeth’s alignment and the condition of your jaw. Based on this evaluation, they can determine if you are a good candidate for Invisalign or if other treatments, such as night guards or alternative dental appliances, are more suitable.

Alternative Solutions for Teeth Grinding

In addition to Invisalign, several alternative treatment options are available for managing bruxism:

  1. Night Guard: A custom-fitted night guard is a dental appliance worn during sleep to help with teeth grinding. These mouth guards create a barrier between the upper and lower teeth, preventing damage and reducing symptoms of bruxism.
  2. Stress Management Techniques: Since these are the common triggers for bruxism, techniques can be beneficial in lowering grinding episodes. Relaxation such as yoga, deep breathing, meditation, and cognitive-behavioural therapy (CBT) can help alleviate stress and minimise bruxism symptoms.
  3. Medication: In some cases, drugs may be given to help manage bruxism symptoms, mainly if stress or anxiety is a contributing factor. A healthcare professional may prescribe muscle relaxants, anti-anxiety medications, and antidepressants to alleviate jaw tension and reduce grinding behaviour.
  4. Behavioural Therapy: Behavioral therapies, such as biofeedback or habit-reversal treatment, can help individuals become more aware of their grinding habits and learn techniques to modify or eliminate them. These therapies focus on breaking the habit of teeth grinding and promoting healthier oral behaviours.
  5. Lifestyle Changes: Making lifestyle adjustments such as avoiding caffeine and alcohol, practising good sleep hygiene, and implementing relaxation techniques before bedtime can help reduce bruxism symptoms. Having a balanced diet and staying hydrated contributes to overall dental health and minimise the likelihood of grinding.
  6. Dental Treatments: Dental treatments such as adjustments, dental restorations (e.g., crowns or bridges), or occlusal equilibration (reshaping the biting surfaces of teeth) may be recommended to alleviate grinding and protect the teeth from damage.

Costs and Insurance Coverage

The cost of Invisalign treatment can vary on the complexity of the case, the treatment duration, and the specific needs of the patient. However, as a general guideline, the typical costs associated with Invisalign treatment include:

  • Consultation: The initial consultation with a dentist to assess your suitability for Invisalign treatment may incur a fee. This consultation allows the dental professional to evaluate your oral health, discuss treatment goals, and create a customised treatment plan.
  • Aligners: The cost of Invisalign aligners typically comprises the bulk of the treatment expenses. The total cost varies depending on the number of aligners needed, the duration, and any additional services or enhancements included in the treatment plan.
  • Follow-up Appointments: Throughout Invisalign treatment, patients are required to attend periodic follow-up appointments with their dental provider. These allow the dentist to track progress, make any adjustments to the treatment plan, and provide guidance on proper aligner care and usage.
  • Insurance Coverage Options and Payment Plans: Insurance coverage for Invisalign treatment may vary depending on the specific terms of your insurance policy. While some may offer partial coverage for orthodontic treatment, including Invisalign, others may not cover the cost at all. It is advisable to review your insurance policy or talk with your insurance provider to know the extent of coverage available for Invisalign treatment.


Invisalign treatment is a modern and effective solution for patients wanting to straighten their teeth while addressing issues such as bruxism. If you are looking for a way to solve your problem and stop grinding your teeth, then you are the right candidate for Invisalign. It will definitely give you a new smile along with the comfort and convenience that it offers compared to traditional braces and other treatment options.
