What Are Neuromodulator Injections?
Neuromodulators are prescription injectable treatments that work by temporarily reducing nerve signals to targeted muscles. By limiting muscle activity, these treatments can soften the appearance of dynamic facial lines caused by repeated expressions and may also be used for certain therapeutic concerns.
At Legacy Dental, neuromodulator treatments may be considered for:
– Forehead lines
– Frown lines between the eyebrows
– Crow’s feet around the eyes
– Jaw clenching and overactive jaw muscles
– Chronic migraines in appropriate patients
– Other concerns related to targeted muscle activity
Because neuromodulators are prescription treatments, a consultation is necessary to determine whether they’re appropriate for your individual needs and treatment goals.

How Do Neuromodulator Treatments Work?
Neuromodulators are injected in small amounts into carefully selected muscles, temporarily reducing the nerve signals that cause those muscles to contract. Treatment is minimally invasive, and the number and location of injections will depend on the area being treated and your individual goals.
For cosmetic treatments, reducing targeted muscle activity can soften dynamic lines while maintaining a natural appearance. Neuromodulator injections may also be considered for therapeutic purposes, including chronic migraines and jaw clenching, when appropriate.
Results are temporary, so repeat treatments may be recommended to maintain your desired outcome.
Neuromodulator Treatment Frequently Asked Questions
How long do neuromodulator injections last?
Results typically last about three to four months, although the duration can vary depending on the treatment area and individual patient. As the effects gradually wear off, muscle activity returns and repeat treatments may be recommended to maintain your results.
How long does it take for neuromodulator injections to work?
Neuromodulator injections do not take full effect immediately. Some patients may begin noticing changes within a few days of treatment, with results developing gradually. Your provider can explain what to expect based on the area being treated.
Are neuromodulator injections safe?
Neuromodulators are prescription medications used for both cosmetic and therapeutic purposes. As with any medical treatment, there are potential risks and side effects, so treatment should be provided by a qualified healthcare professional after determining whether it is appropriate for you.
What is the 4-hour rule after neuromodulator injections?
The “4-hour rule” commonly refers to aftercare instructions that recommend remaining upright and avoiding lying down for approximately four hours after treatment. Aftercare recommendations can vary, so always follow the specific instructions provided by your treating healthcare professional.
Can neuromodulator injections help with migraines?
Neuromodulator treatments may be used to help prevent headaches in adults with chronic migraine. Chronic migraine generally involves headaches occurring 15 or more days per month, with headaches lasting four hours a day or longer. An assessment is necessary to determine whether this type of treatment is appropriate for your symptoms.
Can neuromodulator injections help with jaw clenching?
Neuromodulator injections may be used to temporarily reduce activity in the muscles involved in jaw clenching. By relaxing targeted jaw muscles, treatment may help some patients experiencing symptoms associated with excessive muscle activity. An assessment is necessary to determine the cause of your symptoms and whether neuromodulator treatment is an appropriate option.
Are neuromodulator treatments covered by Alberta Health?
Coverage depends on why the treatment is being administered and whether the patient and treatment meet applicable eligibility requirements. Cosmetic neuromodulator treatments are not generally insured health services, while treatment for certain medical conditions may qualify for coverage. Our team can discuss treatment costs with you, but patients should confirm their individual coverage before treatment.
What is the difference between neuromodulators and dermal fillers?
Neuromodulators and dermal fillers are both injectable treatments, but they work differently. Neuromodulators temporarily reduce targeted muscle activity and are commonly used for expression lines caused by facial movement. Dermal fillers add volume beneath the skin and are generally used to restore or enhance volume, shape, and facial contours.
