Why Was I Prescribed a Night Guard?

Here you are, heading home from your most recent dental visit contemplating why your dentist prescribed an occlusal guard, also referred to as a night guard. After all, you sleep well and certainly don’t notice that you grind your teeth. The fact is, unless your bedmate tells you, you may be completely unaware of your destructive night time habit. It is estimated that 1 in 10 adults grind or clench their teeth regularly in their sleep and most of them don’t realize it until their dentist notices signs of worn down or cracked teeth. Symptoms such as jaw pain, headaches, a clicking sound in your jaw and sensitive teeth have all been attributed to night time grinding. The technical term for tooth grinding is bruxism.

Bruxism can not only impair your sleep quality and damage teeth, but in severe cases it can lead to TMJ (tempromandibular joint) disorders, and can cause gum recession and worsen periodontal disease. Grinding can not only cause damage to your teeth, but can also damage expensive dental work that you have invested in like crowns, bridges and implants.

Luckily there are ways to protect yourself from the harmful effects of night time grinding. Because bruxism can have many causes there is no single treatment to completely eliminate the condition. Stress is a likely factor, so practicing relaxation techniques can help. Smoking and drinking alcohol can also contribute, so it helps to cut back or abstain, at least late into the evening. The main treatment for bruxism is to wear a night guard during sleep. Your dentist takes impressions of your teeth and has an acrylic guard custom made for your mouth. A guard won’t prevent all grinding, but it can redistribute the forces exerted while grinding and protect your teeth and dental work. It may help you get used to keeping your jaw unclenched thus helping during the day while it isn’t being worn. Custom night guards can be costly and often times aren’t covered by insurance, but the protection they offer is invaluable. Inexpensive over the counter night guards are available at drug stores, but being bulkier and not custom fit they are likely to cause additional problems like an altered bite or mouth sores. Discuss such devices with your dentist before using one.
