There are many people who grind their teeth while they sleep, and it’s usually not a cause for concern. However, if you find that your teeth are loose or you’re having trouble chewing, it’s a good idea to see your dentist. They can help you determine if you need to take steps to protect your teeth from further damage. In some cases, nighttime grinding can be a sign of an underlying medical condition, such as sleep apnoea, so it’s important to rule that out. If you’re concerned about your teeth grinding, talk to your dentist. They can help you figure out what’s causing the problem and develop a treatment plan.
