Medications and TMJ Grinding and Clenching

Teeth grinding and clenching

There are commonly prescribed psychotropic medications/drugs that can contribute to teeth grinding and clenching when using antidepressant medications, SSRI (selective serotonin reuptake inhibitors), anti panic agents as well as anti obsessive agents. They are listed in this diagram.

Teeth grinding and clenching (a condition in which you grind, gnash or clench your teeth) has been reported by people with osteoporosis, depression, stress and anxiety, osteopenia, attention deficit hyperactivity disorder. (latest reports from 2,537 Teeth grinding and clenching patients).

SSRI or selective serotonin reuptake inhibitor refer to any of a class of antidepressants (as fluoxetine or sertraline) that inhibit the inactivation of serotonin by blocking its reuptake by presynaptic nerve cell endings.

There have been several reported incidents of iatrogenic bruxism (involuntary clenching or grinding of the teeth). Diurnal bruxism (Micheli et al, 1993) has been associated with dopaminergic blockade, and nocturnal bruxism.

Nocturnal bruxism has been reported with venlafaxine, a serotonin/noradrenaline reuptake inhibitor, which responded to gabapentin (Brown & Hong, 1999), as well as three selective serotonin reuptake inhibitors (SSRIs), paroxetine (Romanelli et al, 1996), fluoxetine and setraline (Ellison & Stanziani, 1993).

On Feb, 26, 2016: 37,299 people reported to have side effects when taking Gabapentin (Neurontin).  Among them, 48 people (0.13%) have Teeth Grinding And Clenching.

Benzodiazepines are widely prescribed for a variety of conditions, particularly anxiety and insomnia.  Four of them, alprazolam (Xanax), clonazepam (Klonopin), diazepam (Valium) and lorazepam (Ativan), are considered among the top 100 most commonly prescribed medications.  They are relatively safe and, with overdose, rarely result in death. However, used chronically, benzodiazepines can be addicting.  These agents are often taken in combination with other drugs of abuse by patients with addiction disorders.  Alternatives to benzodiazepines may be preferable and may include antidepressants, anticonvulsants, buspirone, antihypertensive agents and the newer neuroleptic medications.

Note: Caution must be used when prescribing benzodiazepines to patients with a current or remote history of substance abuse.  Addictions to these kind of medications can result in chronic dependence. Those who have been prescribed benzodiazapines for long-term and have been taking these medications directed by their physician have been shown to become dependent.

Benzodiazepines are also widely prescribed for other reasons, such as muscle spasticity, convulsive disorders, presurgical sedation, involuntary movement disorders, detoxification from alcohol and other substances, and anxiety associated with cardiovascular or gastrointestinal conditions

Toxicity and Side Effects:

Benzodiazepines carry an extremely low risk of acute toxicity. However, benzodiazepines often are used with other types of medications, including other drugs with abuse potential, and these drugs can enhance the toxic effects of benzodiazepines.

Characteristics of these type of medications are:
