Causes and effects of teeth grinding

Understanding teeth grinding

Teeth grinding, or bruxism, is a condition characterized by the clenching or grinding of teeth, usually during sleep. It is estimated that about 10% of adults and up to 15% of children experience bruxism at some point in their lives. The exact cause of bruxism is not fully understood, but it is believed to be a combination of physical, psychological, and genetic factors.

Causes of teeth grinding

Several factors contribute to the development of bruxism, including stress and anxiety, misaligned teeth, sleep disorders (such as sleep apnea), certain medications, and lifestyle habits like excessive alcohol consumption or tobacco use. The exact cause may vary from person to person, making it important to identify and address the underlying factors contributing to teeth grinding.

Effects of teeth grinding

Bruxism can have detrimental effects on both oral health and overall well-being. The continuous grinding and clenching of teeth can lead to tooth enamel erosion, tooth sensitivity, chipped or cracked teeth, and even tooth loss. It can also cause jaw muscle pain, headaches, earaches, disrupted sleep, and TMJ (temporomandibular joint) disorders. Therefore, it is essential to seek treatment and preventive measures, such as using night guards, to mitigate these effects.

How do night guards work?

Night guards as a protective barrier

Night guards act as a protective barrier between the upper and lower teeth, preventing direct contact and the resulting damage caused by grinding or clenching. By absorbing the excessive force exerted during bruxism, night guards distribute the pressure evenly across the teeth, reducing the risk of tooth fractures, enamel wear, and gum tissue damage.

Cushioning effect of night guards

Night guards provide a cushioning effect by creating a physical barrier between the upper and lower teeth. This cushioning effect helps absorb the impact of grinding, minimizing the strain on the jaw muscles and the temporomandibular joint (TMJ). By creating a more even distribution of forces, night guards help alleviate muscle tension and reduce the risk of TMJ disorders associated with bruxism.

Reducing tension in the jaw

One of the primary causes of bruxism is muscular tension and stress in the jaw area. Night guards help alleviate this tension by providing a stable and padded surface for the teeth to bite against. The cushioning effect of the night guard can help relax the jaw muscles, reducing the propensity for grinding and clenching during sleep.

Preventing teeth damage

Night guards act as a physical barrier, preventing direct contact between the upper and lower teeth. By doing so, they help prevent enamel wear, tooth fractures, and other damage resulting from the excessive forces exerted during teeth grinding. By wearing a night guard, you significantly reduce the risk of long-term dental problems associated with bruxism.

Alleviating bruxism symptoms

Night guards also help alleviate the symptoms associated with bruxism. By reducing the impact of grinding and clenching, night guards can provide relief from jaw pain, headaches, and earaches caused by the strain on the jaw muscles and joints. Additionally, night guards promote better sleep quality by minimizing disruptive grinding noises and improving comfort.

Types of night guards

Standard night guards

Standard night guards are readily available over-the-counter and do not require a dentist’s involvement for fitting. They come in a one-size-fits-all design and are made of a soft, moldable material that can be trimmed to fit the individual’s mouth. While standard night guards offer convenience and affordability, they may not provide the same level of comfort and protection as custom-fit options.

Custom-fit night guards

Custom-fit night guards are specially designed and fitted to an individual’s teeth by a dentist or dental laboratory. They require impressions of the teeth to ensure a precise fit and are made from durable materials that offer superior protection and longevity. Custom-fit night guards provide optimal comfort and effectiveness, making them the preferred choice for individuals with moderate to severe bruxism.

Boil-and-bite night guards

Boil-and-bite night guards offer a combination of customization and convenience. They are made of a thermoplastic material that softens when boiled and can be molded to fit the individual’s teeth. Boil-and-bite night guards provide a better fit compared to standard night guards and are more affordable than custom-fit options. They are suitable for individuals with mild to moderate bruxism who desire a more personalized fit.

Benefits of wearing night guards

Preventing teeth damage

One of the primary benefits of wearing night guards is their ability to prevent teeth damage caused by bruxism. Night guards cushion the teeth and distribute the grinding forces evenly, reducing the risk of enamel wear, chipping, fractures, and other dental issues associated with bruxism.
