Teeth grinding (a.k.a. bruxism) has become a significant problem, with dentists saying that teeth grinding has increased, especially with the distress caused by the COVID-19 pandemic. It can cause considerable damage to your teeth, which is why you should talk to your dentist about a mouth guard for teeth grinding.
While there are multiple methods for solving teeth grinding, a mouth guard is one of the most effective, particularly if your teeth grinding occurs while you’re asleep. In this article, we’ll cover what a mouth guard for teeth grinding is, and how it can help.
What is teeth grinding?
Teeth grinding is a condition in which a person clenches or grinds their teeth involuntarily. It can occur during the day or night, and may happen without the person even realising it. Teeth grinding can be mild or severe, and can cause a range of problems depending on the frequency and intensity of the grinding. Some of the most common symptoms of teeth grinding include headaches, jaw pain, worn teeth, and tooth sensitivity. It is important to seek treatment for teeth grinding, as it can cause significant damage to your teeth and overall oral health if left untreated.
How does teeth grinding damage teeth?
There are multiple different ways in which teeth grinding can damage your teeth over an extended period of time.
For example, the constant grinding and clenching motion can wear down the enamel on the teeth, leading to sensitivity and an increased risk of cavities. Additionally, it can cause teeth to become chipped or cracked, and even lead to fractures or breakage in severe cases.
Teeth grinding can also cause damage to dental restorations such as fillings, crowns, and bridges; as these restorations are not designed to withstand the forces generated by grinding and clenching, and may become loose or even dislodged as a result.
In some cases, teeth grinding can also lead to gum recession, which can expose the roots of the teeth and cause sensitivity and pain, increasing the risk of tooth decay and gum disease.
How does a mouth guard for teeth grinding help?
Mouth guards help with teeth grinding by acting as a cushion between the upper and lower teeth to prevent them from coming into contact with each other. Mouth guards are typically made of a soft, pliable material that is comfortable to wear and can be adjusted to fit the individual’s teeth. They can be custom-made by a dentist or purchased over-the-counter.
When wearing a mouth guard, the forces generated by teeth grinding are absorbed by the appliance rather than the teeth themselves. This helps to reduce the wear and tear on the teeth and prevent damage such as chipping, cracking, and sensitivity.
In addition to protecting the teeth, a mouth guard can also help to relieve other symptoms of teeth grinding, such as headaches, jaw pain, and muscle tension. It can also help to reduce the frequency and intensity of teeth grinding over time.
What are the different causes of teeth grinding?
There are many different factors that can contribute to teeth grinding, and the causes can vary from person to person. It’s important to note that teeth grinding can have multiple causes, and in many cases, it may be a combination of factors that contribute to the problem.
Some of the most common causes of teeth grinding include:
- Emotional stress, anxiety, and tension, as people may grind their teeth as a way to cope with stress or to release tension.
- Sleep disorders such as sleep apnea, which causes pauses in breathing during sleep.
- A misaligned bite, crooked teeth, or other dental problems – all of which can contribute to teeth grinding.
- Certain medications, such as antidepressants, as they can cause teeth grinding as a side effect.
- Alcohol, caffeine, and tobacco use, all of which have been linked to an increased risk of teeth grinding.
- Some medical conditions, such as Parkinson’s disease, Huntington’s disease, and acid reflux.
- Genetic components, as it tends to run in families.
What are the different types of mouth guards available?
There are several types of mouth guards available to help with teeth grinding. The type of mouth guard recommended will depend on your individual needs and the severity of your teeth grinding. Here are some of the most common types of mouth guards:
Custom-made mouth guards
These are made by a dentist and are designed to fit the individual’s teeth perfectly. They are typically the most effective and comfortable option, but they can also be the most expensive.
Boil-and-bite mouth guards
These are available over-the-counter and can be moulded to fit the individual’s teeth by boiling them in water and then biting down on them. They are a more affordable option, but may not fit as well as custom-made mouth guards.
Stock mouth guards
These are also available over-the-counter and come pre-formed in standard sizes. They are the least expensive option, but are often bulky and may not fit well.
Hybrid mouth guards
These are a combination of custom-made and boil-and-bite mouth guards. They are designed to fit the individual’s teeth, but also have a layer of material that can be moulded to provide extra comfort.
It’s important to note that while over-the-counter mouth guards can provide some protection against teeth grinding, they may not be as effective as custom-made mouth guards. It’s best to consult with a dentist to determine the best type of mouth guard for you.
What are the advantages of using a custom-made mouth guard over a store-bought one?
A custom-made mouth guard may be more expensive than an over-the-counter alternative. However a custom-made mouth guard tends to be a better investment in the long run; as it provides better protection, comfort, and durability against teeth grinding compared to store-bought options.
The advantages of a custom-made mouth guard over a store bought one include;
- Custom-made mouth guards are designed to fit the individual’s teeth perfectly, which can provide better protection against teeth grinding. A better fit also means that the mouth guard is more comfortable to wear and less likely to fall out during sleep.
- Custom-made mouth guards are less likely to wear down or break compared to over-the-counter options because they are made from high-quality materials that are durable and long-lasting.
- Custom-made mouth guards can be personalised to meet the individual’s needs. They can be designed to address specific dental issues such as a misaligned bite or crooked teeth.
- When a dentist creates a custom-made mouth guard, they can provide guidance on how to properly use and care for the appliance. They can also monitor the individual’s progress and make adjustments as needed.
What factors should I consider when choosing a mouth guard for teeth grinding?
There are many different factors to consider when choosing the right mouth guard for teeth grinding, including;
Material
Mouth guards are made from a variety of materials, including hard acrylic, soft silicone, and dual laminate. Each material has its own pros and cons, so it’s important to choose one that is comfortable to wear and provides adequate protection.
Fit
A mouth guard that doesn’t fit properly can be uncomfortable to wear and may not provide adequate protection against teeth grinding. Custom-made mouth guards are designed to fit the individual’s teeth perfectly, while over-the-counter options may require some adjustments to achieve a good fit.
Durability
Over time, mouth guards can wear down or break, which can compromise their effectiveness. It’s important to choose a mouth guard that is made from durable materials and can withstand the wear and tear of teeth grinding.
Comfort
A mouth guard that is uncomfortable to wear may discourage regular use, which can reduce its effectiveness. It’s important to choose a mouth guard that is comfortable to wear and doesn’t interfere with breathing or speaking.
Cost
Custom-made mouth guards can be more expensive than over-the-counter options, but they are also more effective and durable. It’s important to choose a mouth guard that fits your budget while still providing adequate protection.
Dental issues
Some individuals may have dental issues, such as a misaligned bite or crowding, that require a specialised mouth guard. It’s important to consult with a dentist to determine the best type of mouth guard for your individual needs.
How do I care for my mouth guard?
Once you have a mouth guard to help with your teeth grinding, it is important that you care for it properly.
This is done in multiple ways, including;
- Clean it daily with water to remove any debris or bacteria and use a soft-bristled toothbrush and mild soap to gently clean it at least once a week.
- When you’re not using your mouth guard, store it in a case that allows it to air-dry, as this will help prevent the growth of bacteria and prolong its lifespan.
- Do not expose your mouth guard to high temperatures, such as hot water or direct sunlight, as this can warp or damage the material.
- Do not chew on your mouth guard as this can cause it to tear or break.
- Keep it out of reach of pets that may try to chew on it or swallow it.
- Replace your mouth guard as recommended by your dentist or if you notice any signs of wear or tear.
