Botox - Botulinum toxin
Most of you will have heard of `botox' (botulinum toxin). In recent years it's been used extensively for cosmetic purposes. When botox is injected into muscles, they become paralysed for about three or four months. Because of this botox can be used to treat muscle spasms. It's also often used to reduce and prevent wrinkles by injecting it into facial muscles.
What's this got to do with bruxism and teeth grinding?
Recently botox has been used to treat bruxism! The masseter muscles (the ones that control your jaw) are injected with a dose of botox. Greatly weakening it, and thereby reducing the force it can clench the teeth with. This means that wear on the teeth due to grinding is greatly reduced. Other bruxism symptoms such as damage to the TMJ (temporo-mandibular joint) and headaches should also be reduced or eliminated.
Another benefit to treatment with botox is that the masseter muscles should atrophy. Bruxers often have enlarged messeter muscles due to the extra excersize they get from strong grinding and clenching. This leads to even more rapid wearing of the teeth (as the muscles become stronger) and also altered facial appearance. This means that treatment of teeth grinding with botox should lead to a more normal (and presumable more attractive) facial appearance!
Downsides to botox
So far this all sounds wonderful but botox is no panacea!
First of all a single treatment of botox isn't cheap (upwards of £200). Second, botox is no cure, it's a control just like a nightguard; each treatment will only last around three to four months, then you need another treatment. This makes botox a rather expensive option when compared to nightguards, especially over-the-counter guards.
Treatment with botox also has the potential to go wrong. It's important that the dose is correct. If it's too low then the treatment will have little to no effect. If it's too high you may find yourself unable to eat solids! After all, the masseter muscles are there for a reason. Whilst treatment with botox aims to weaken the muscles, they need to remain strong enough to chew food. Botox, more accurately named `Botulinum Toxin', is a toxin! In fact it's the most toxic known protein. For this reason, doses given medically are kept very low and care must be taken to deliver it only to the correct area. Botox injections can also sometimes lead to bruising that lasts for around 6 weeks.
Summary
Bruxism and teeth grinding can be treated using injections of botox to the jaw muscles. Botox isn't a cure but rather a control and treatments are required every three to four months. The treatment may well be both more effective and more comfortable than nightguards for many people. However, it's an expensive option that will be out of reach for most. Treatment with botox has greater potential for complications when compared to nightguards, but has the added benefit of atrophying the jaw muscles leading to a more normal facial appearance.
