From the Research

After initial use of a mouth guard for bruxism, expect some discomfort and adjustment period lasting 1-2 weeks, as reported in various studies 1, 2, 3, 4. Your mouth may feel strange, speech might be temporarily affected, and you might experience increased salivation. Some patients report mild jaw soreness as muscles adjust to the new positioning. These symptoms typically resolve as you adapt to wearing the device. You should notice a gradual reduction in morning jaw pain, headaches, and tooth sensitivity over several weeks of consistent use. The mouth guard won't necessarily stop the grinding behavior itself but protects teeth from damage. Clean your guard daily with a soft toothbrush and mild soap (avoid toothpaste which can be abrasive), and store it in a ventilated container when not in use. If discomfort persists beyond two weeks or if you experience increased pain, jaw clicking, or difficulty closing your mouth normally, consult your dentist for adjustments. Most patients require periodic replacement of their mouth guards (typically every 1-3 years) as they can wear down from continued grinding.

Key points to consider:

  • The most recent study 1 from 2024 highlights the importance of sleep hygiene and the potential use of oral devices for adults with severe sleep bruxism.
  • Another study 2 from 2017 discusses the role of mouthguards in preventing and reducing sports-related trauma, which can be applied to the context of bruxism.
  • The study 3 from 2008 investigates the relationship between tooth grinding patterns during sleep bruxism and dental status, emphasizing the need for proper mouthguard use.
  • The review 4 from 2016 provides an overview of bruxism cosmetic rehabilitation, which can be useful for patients with severe tooth wear due to sleep bruxism.

Overall, the use of a mouth guard for bruxism can be an effective way to protect teeth from damage and reduce symptoms, but it's essential to follow proper care and maintenance instructions and consult a dentist if any issues arise.
