Bruxism (derived from Greek βρυγμός, masculine noun - grinding *) is grinding of the teeth. The infinitive is "to brux".
This is an oral para-functional habit observed in a large number of people occasionally and, in a smaller number, habitually. The mechanism of causation is tension and spasm of the muscles used for mastication. The term also refers to clenching of the teeth, which causes similar problems.
Often, it occurs during sleep; even a short nap may induce it. In a typical case, the canines and incisors are commonly moved against each other laterally, i.e. with a side to side action. This abrades tooth enamel, removing the sharp biting surfaces and flattening the edges of the teeth. Sometimes, there is a tendency to grind the molars together, which can be loud enough to wake a sleeping partner.
