A temporalis twitch, or muscle spasm, can be caused by several factors, including stress, fatigue, or excessive jaw clenching, often associated with conditions like bruxism. Dehydration and electrolyte imbalances can also contribute to muscle twitching. In some cases, underlying neurological issues or nutritional deficiencies may play a role. If the twitching persists, it's advisable to consult a healthcare professional for further evaluation.
