Teeth Grinding or Clenching During Sleep?
What is Teeth Grinding Bruxism?
Teeth Grinding & Clenching is an involuntary condition that often occurs unconsciously during sleep. It is known as Bruxism. Bruxism is excessive clenching and grinding of teeth which is not part of normal chewing movements.
Many individuals remain unaware of their condition until they experience symptoms such as jaw soreness, morning headaches, or noticeable signs like worn-down, chipped, flattened, loose, or fractured teeth. While occasional grinding may seem harmless,excessive clenching and grinding of teeth are not healthy actions and can occur during the day or at night. Due to lack of conscious control in sleep, frequent or severe teeth grinding (Bruxism) can lead to enamel loss, tooth fractures, jaw pain, headaches, or can potentially damage the jaw joints (TMJ) and teeth.
