Sometimes people when sleeping can grind their teeth. It is a symptom of bruxism - disease, which manifests itself in the fact that a person unconsciously grinds teeth when sleeping or in case of emotional tension. But dentists in Mexico can treat such unpleasant disease. Bruxism can occur in kids and adults. Treatment of bruxism is still a very difficult problem in dentistry because of the difficulty in identifying the causes of the disease. Bruxism in children at an early age often does not require treatment and resolves on its own in the preschool years. Bruxism in adults demands treatment. The sooner bruxism in adults is diagnosed, the more effective will be its treatment.
