BOTOX or Botulinum toxin (BoNT-A), has been used for quite some time as a cosmetic tool in physicians and dentists offices. It can be utilized to make us look and feel younger. Did you know that botox has many other medical uses? It turns out that botox can be used to aid in therapy for many dental, facial pain disorders. It has been reported that approximately 16% of dentists in North America now use BoNT-A in their offices for cosmetic and therapeutic applications.
Botox acts by inhibiting the release of acetylcholine. Acetylcholine depolarizes the motor end plate of the muscle and will cause a muscle contraction. By inhibiting the release of acetylcholine, Botox effectively will either reduce the intensity of the contraction of the muscle or will eliminate the contraction altogether, depending on the amount of Botox used. Essentially, BoNT-A neurotoxin causes a temporary muscle paralysis. Each botox treatment can usually last between 3-6 months as the muscle initiates new acetylcholine receptors and the growth of branches from the neurons to form new synaptic contacts. Gradually the muscle returns to its full function and with no side effects at all.
Botox And Dental Medicine
Botox can be used for the following disorders:
-Temperomandibular Joint Disorder (TMD) and Facial Pain Management – TMD is a very difficult disorder to treat since its symptoms are varied and complex. The goal of treatment in TMD has been to provide non -invasive, reversible treatment options. Surgery is an option, although rarely used, due to limited success. Botox gives the dentist the ability to relieve TMD and facial pain symptoms for a short period of time (from weeks – months for each treatment). In TMD and facial pain disorder, there are muscular trigger points that radiate outward through the nerve bundles. The injection of Botox into these trigger point areas, “freezes ” the ability of the muscle by paralyzing it for a while, can help relieve the intensity of the TMJ muscle contractions. The relief can last up to three months. For trigger point injections, it makes much more sense to use Botox because the effects will last for three months and you are actually helping relieve the intensity of the contraction of the muscle, which is usually in spasm.This temporary muscle paralysis makes Botox a great tool in the treatment and management of TMD and facial pain disorders. The use of Botox products in TMD and facial pain management therapy can give us a totally new insight as to helping these patients who have had trouble getting relief previously.
-Teeth Clenching (Bruxism) – This treatment becomes somewhat tricky as the dose is very important here. Excessive botox into the area of the mastication muscles can paralyze these muscles and disrupt a person’s ability to chew and speak. Too small a dose and it has little to no effect. The proper dose will reduce the intensity of the muscles contraction, allowing the patient to still be able to chew and speak properly. When done correctly, the patient will see relief from facial pain and limit the damage done by the teeth clenching, as the force is no longer there to do damage to oral tissues. Using the right amount of Botox will decrease the intensity of contractions of the muscles of mastication as well as give you full ability for chewing, eating properly, and speaking. The relief afforded to patients by Botox can help eliminate facial pain, greatly reduce their TMD symptoms and can significantly help the other associated treatments of periodontal disease by removing bruxism from the equation of dental treatment.
-Orthodontics – Our muscles play a huge role in where our teeth line up. Following orthodontic therapy some patients teeth will relapse and this may be due to placement of that individual’s musculature. For many patients an over active mentalis muscle is often the cause of relapse of the teeth and may cause spasm of the muscles. Botox gives your cosmetic dentist the ability to reduce these spasms and contractions allowing for limited relapse following orthodontic treatment.
-Treatment of Migraine, and other Headaches – Generally, migraines have been a source of unknown pain and discomfort for many patients. Migraines routinely have multiple symptoms beyond just a simple headache. These symptoms can include nausea, dizziness, and even sensitivity to light. The use of Botox can give relief to these symptoms. The placement of a few well placed injections around the temples, forehead, and neck/shoulder area can ease these symptoms by preventing the pain signals to reach the nerve bundles in the head and neck. This can also relieve severe headaches in the forehead region, if you suffer from them frequently. This can be quite expensive but for those suffering it can be well worth the cost to feel relief from extensive pain.
-Controlling Excess Saliva Production (also called sialorrhea) – The more common term for this is drooling. While there are other treatments for this, botox gives the ability to stop the excessive salivary production by injecting into the parotid and submaxillary glands. Again, this treatment is very dose specific. Too high a dose can disrupt a person’s chewing ability and also lead to dry mouth (xerostomia).
-Facial Asymmetry – For many patients, the muscles of the face may be asymmetrical leading to an imbalanced look to the face. Botox has the ability to restore that symmetry by re balancing the facial muscles. Eyebrow lift, or depression of the brow can be enhanced with properly placed botox injections.
-Gummy Smile – This is shown as a smile that shows too much gum tissue. This usually is the result of the lip rising too high upon smiling. Botox injections into the upper lip weakens the retractor muscles of the upper lip so that it will not raise as high and your smile will appear better-balanced.
-Trigeminal Neuralgia- This extremely painful condition can be brought about by something as simple as air blowing on your face. Freezing a few select muscles on the affected side of the face can bring relief from extreme pain, as well as piece of mind. Not having to worry about accidentally setting off the facial pain can give you you control of you life again.
Botox and Dentistry Conclusion
As with any botox las vegas application, training is critical. The dentist placing the injections should be well trained with extensive classroom and patient hours. This will give you confidence that your dentist is well versed in not only a person’s anatomy but also in correct dosing regimen of the botox for the problem at hand. Too little and there will be no relief from symptoms while too much botox can lead to disabling effects. Botox gives patients and exceptional dentists new possible treatments that can lead to better lives for all of us.
