Pathological tooth wear of a 23-year-old female case participant. In general, the female is healthy but she suffers from daily regurgitation and/or heartburn for about two years. She complained of teeth grinding during sleep every day. She rarely experiences exposure to acids from the environment or diet. She hardly rinses or brushes after regurgitation. Extensive tooth wear into dentin was identified, especially on the palatal superficies of upper incisors and canines (pointers).
