When most people hear the word “Botox,” they think of a specific injectable treatment used to relax muscles. However, Botox is actually a brand name, and there are several different botulinum toxin formulations available today.
Botox was originally produced exclusively by Allergan and became so widely recognized that its name is now often used as a general term for botulinum toxin treatments. It is similar to how people sometimes use the word “Kleenex” when referring to facial tissues, regardless of the actual brand.
Technically, Botox with a capital “B” refers specifically to the Allergan product. The term “botox” is also commonly used more broadly when discussing similar botulinum toxin products made by other manufacturers.
For patients dealing with temporomandibular disorders (TMD), jaw pain, muscle tension, or teeth grinding, understanding the different types of botulinum toxin can help provide a clearer picture of the treatment options available.
What Is Botulinum Toxin?
Botulinum toxin is a purified protein that temporarily reduces muscle activity by interfering with the signals that cause muscles to contract.
While botulinum toxin is widely known for its cosmetic applications, healthcare professionals also use it for a variety of medical and dental purposes. In dentistry, it may be used to help manage conditions associated with excessive or overactive muscle activity, including certain cases of TMD, jaw tension, and bruxism.
By relaxing targeted muscles, botulinum toxin treatment may help reduce excessive contractions and relieve some of the discomfort associated with these conditions.
What Are the Different Types of Botox?
Several botulinum toxin formulations are currently used by healthcare professionals. Although they work in similar ways, there are differences in their formulations, diffusion characteristics, dosing, and how individual patients may respond.
Botox (OnabotulinumtoxinA)
Botox is the original and most widely recognized botulinum toxin formulation.
Its active ingredient is onabotulinumtoxinA. When injected into specific muscles, Botox temporarily reduces the nerve signals responsible for muscle contractions.
For patients experiencing symptoms related to overactive jaw muscles, reducing these contractions may help decrease tension and discomfort.
Dysport (AbobotulinumtoxinA)
Dysport contains abobotulinumtoxinA and works similarly to Botox by temporarily reducing muscle activity.
One difference is its diffusion characteristics. Dysport may spread somewhat more from the injection site than Botox, which can make it useful when treating certain larger muscle areas.
Because Dysport and Botox use different dosing systems, their units are not interchangeable. An experienced healthcare professional determines the appropriate product and dosage based on the treatment area and the patient’s individual needs.
Xeomin (IncobotulinumtoxinA)
Xeomin contains incobotulinumtoxinA.
Unlike some other botulinum toxin formulations, Xeomin does not contain certain accessory proteins. Because of this, it is sometimes referred to as a “naked” or highly purified form of botulinum toxin.
This formulation may be considered when determining which product is most appropriate for an individual’s treatment plan, particularly when repeated treatments are anticipated.
Jeuveau (PrabotulinumtoxinA-xvfs)
Jeuveau contains prabotulinumtoxinA-xvfs and is one of the newer botulinum toxin products available in the United States.
Sometimes marketed as “Newtox,” Jeuveau works by temporarily blocking signals between nerves and muscles, reducing muscle contractions in the treated area.
Like other botulinum toxin products, its formulation and dosing are specific to the product and should be selected and administered by a properly trained healthcare professional.
Are All Types of Botox the Same?
Although Botox, Dysport, Xeomin, and Jeuveau are all botulinum toxin type A products, they are not identical.
Differences can include:
- Formulation
- Potency and dosing
- Diffusion or spread after injection
- Accessory proteins
- Onset and duration of effects
- Individual patient response
This is why the number of units used with one product cannot simply be substituted for the same number of units of another.
The right formulation depends on the area being treated, the desired effect, previous treatment experiences, and other individual considerations.
How Is Botulinum Toxin Used for TMD and Jaw Pain?
Some TMD symptoms are associated with overactivity or tension in the muscles responsible for moving the jaw. Patients who clench or grind their teeth may repeatedly contract these muscles, potentially contributing to soreness, fatigue, headaches, or other discomfort.
Botulinum toxin can be strategically injected into selected muscles to temporarily reduce excessive muscle activity.
By decreasing the strength of involuntary or excessive contractions, treatment may help relieve muscle tension and associated discomfort in appropriately selected patients.
Botulinum toxin does not address every possible cause of TMD, however. Temporomandibular disorders can involve the muscles, jaw joints, bite, or a combination of factors. A thorough evaluation is important before determining whether botulinum toxin should be part of a patient’s treatment plan.
Which Type of Botox Is Best for TMD?
There is not one botulinum toxin formulation that is automatically best for every patient.
The appropriate choice depends on factors such as the muscles being treated, treatment goals, previous response to botulinum toxin, dosage requirements, and the characteristics of the individual formulation.
More important than choosing a product based solely on its brand name is determining whether botulinum toxin is appropriate for the patient’s condition and developing a treatment plan based on the underlying source of their symptoms.
Botulinum Toxin Treatment in Sacramento, CA
Dr. Andrea Joy Smith uses her knowledge of facial anatomy, jaw function, and orofacial pain to evaluate patients experiencing TMD symptoms, jaw pain, muscle tension, and related concerns.
When botulinum toxin treatment is appropriate, the specific formulation and treatment approach can be selected according to the patient’s individual needs rather than relying on a one-size-fits-all solution.
If you are experiencing persistent jaw tension, discomfort, or other symptoms associated with TMD, an evaluation can help identify contributing factors and determine whether botulinum toxin treatment may be an appropriate part of your care.
