Bruxism is a parafunctional jaw habit (an unconscious movement of the manducatory tract) either by clenching the teeth (centred bruxism) or lateral, grinding movements. This parafunction allows children to get rid of their milk teeth, and the habit generally disappears with the appearance of adult teeth, but it can manifest itself as a condition among adults during the day, and more frequently at night. It is mainly an unconscious habit.
Consequences of bruxism (teeth grinding)
– Grinding and rubbing of the teeth, most often at night and making noises audible to the patient’s partner.
– This leads to abnormal wear of the teeth (the first affected are the exposed edges of incisors and canines, and the occlusal (top) surface of molars), leading to damage to the alveolo-dental ligaments and the alveolar bone, resulting in movement and tooth loss.
– Hypertrophy of the lifting muscles of the mandible (masseter and temporal) and disequilibrium between the jaw’s downward and upward movement muscles.
This hypertrophy can:
1) Cause problems in temporal-mandibular articulation and pain when chewing (sometimes the only solution is to mash up or to purée food), limited ability to open the mouth, cracking joints when the mouth is opened and closed, and hearing problems.
2) Have an aesthetic impact due to hypertrophy of the temporal and masseter muscles 3) block the Stenon canal (the parotid gland canal) and be the origin of a parotid (inflammation of the parotid gland) or a salivary gland inflammation.
Botox treatment for bruxism (teeth grinding) at the Paris medical clinic
Botox injections in the masseter and/or temporal muscles are an effective and lasting treatment for bruxism and its consequences (including the unsightliness of hypertrophic muscles, and the injections allow for facial refinement/narrowing).
A single session suffices for two thirds of patients. No secondary effects have been observed if the injecting practitioner is experienced (the diffusion or spread of the toxin, due to a bad injection, to the surface muscles of the face is the origin of the ‘frozen’ smile and lasts for about 6-8 weeks).
Botulinum toxin is injected specifically into the muscle concerned and in a concentrated quantity in order to avoid it spreading to the muscles which are not targeted by the treatment.
