Paradoxical bulging (jaw muscle)

Part of the muscle bulging outwards when the teeth are clenched after botulinum toxin has been injected into the jaw muscle. It is uncommon; it has been attributed to the medicine not spreading evenly through the whole muscle. If you notice it, show it to your physician; an additional treatment may be needed.
