Nightguards are dental appliances that are worn over the teeth while sleeping. They are typically made of soft and flexible materials such as silicone or acrylic, which conform to the shape of the teeth for a secure fit. The main purpose of a nightguard is to protect the teeth from the negative consequences of bruxism, or teeth grinding and clenching. While they cannot cure bruxism, nightguards provide a cushioning effect that absorbs the force of grinding and clenching, preventing teeth from hitting against each other. They can also help treat sleep apnea by shifting and repositioning the jaw to open the airway during sleep. It is recommended to wear a nightguard every night and to place it in position at least 30 minutes before sleeping to allow the mouth to adjust.

What You'll Learn

Nightguards are for protecting teeth from grinding and clenching
Nightguards are a type of mouthguard that is designed to protect teeth from grinding and clenching, otherwise known as bruxism. Bruxism can cause significant damage to teeth, wearing them down over time and causing them to become shorter or flatter. It can also lead to jaw pain, headaches, and other dental problems. Nightguards act as a barrier between the upper and lower jaws, absorbing the forces produced by grinding and clenching and providing a cushioning effect that protects the teeth and jaw joint.
Nightguards are typically worn while sleeping, as most people tend to grind and clench their teeth during sleep. They can be worn at any time, day or night, but it is important to wear them consistently to protect the teeth from damage. Custom-made nightguards that are fitted by a dental professional are generally recommended, as they offer the most comfort and protection. These guards are made by taking an impression of the patient's teeth and molding the guard to fit their exact dental anatomy. While custom-made nightguards are more expensive, they are more effective at protecting against teeth grinding and sports-related injuries than store-bought options.
It is important to keep nightguards clean and store them properly when not in use. They should be rinsed in cool or cold water and scrubbed with a toothbrush daily. It is also important to air-dry the nightguard before placing it in a sturdy, vented plastic case to prevent the growth of bacteria and other microorganisms. Additionally, it is recommended to wear the nightguard for at least 30 minutes before bedtime to allow the mouth to adjust and fall asleep faster. Some people may experience an adjustment period with some mild discomfort and inconvenience when first using a nightguard.
Overall, nightguards are an effective way to protect teeth from the damaging effects of grinding and clenching. They can help prevent dental issues such as cracked teeth, jaw pain, and headaches caused by bruxism. By absorbing the forces produced by these habits, nightguards provide a cushioning effect that keeps teeth and jaws safe from harm.

They can be store-bought or custom-made
Nightguards are dental appliances worn over the teeth while sleeping. They are used to prevent teeth grinding, jaw clenching, and damage to the teeth. They can be store-bought or custom-made.
Store-bought nightguards are readily available and cheaper than custom-made nightguards. However, they may not be as effective or comfortable as custom-made nightguards. There are two main types of store-bought nightguards: stock nightguards, which can be used directly out of the box, and boil-and-bite nightguards, which can be slightly customised at home by boiling them to soften the material and then biting on them to change the shape to fit your mouth.
Custom-made nightguards, on the other hand, are created by a dentist to fit your exact dental anatomy. They tend to be more comfortable and effective in protecting against teeth grinding and sports-related injuries. A custom nightguard is created by taking an impression of your teeth, and then moulding the guard over the impression using a special material. While custom-made nightguards are more expensive, they offer superior comfort and protection.
It is important to note that nightguards should be properly cleaned and stored when not in use. They should be rinsed in cool or cold water and brushed with a toothbrush and soap or toothpaste. They should be allowed to air dry and stored in a sturdy, vented plastic case to prevent bacteria and microorganism growth. Additionally, nightguards should not be exposed to extreme heat, such as direct sunlight, hot water, the microwave, or the dishwasher, as this can cause warping.
Whether you choose a store-bought or custom-made nightguard, it is important to allow some time for your mouth to adjust to wearing it. It is recommended to place the nightguard in position at least 30 minutes before bedtime and to wear it consistently to help your mouth get used to it.

They can be cleaned with cold water and a toothbrush
Nightguards are dental appliances worn over the teeth while sleeping. They are designed to prevent teeth grinding, also known as bruxism, and to protect the teeth from damage caused by clenching or grinding. They are typically made from soft and flexible materials, such as silicone or acrylic, which conform to the shape of the teeth for a secure fit.
To ensure the comfort and longevity of your nightguard, it is important to keep it clean. Cleaning your nightguard properly will also help prevent the buildup of bacteria and other microorganisms. Here are some detailed instructions for cleaning your nightguard with cold water and a toothbrush:
- Rinse the nightguard with cold or cool water after each use. Avoid using hot water, as this can cause the nightguard to warp and change shape.
- Use a toothbrush to gently scrub the nightguard. You can use your regular toothbrush, but it is recommended to dedicate a separate toothbrush specifically for cleaning your nightguard.
- You may use a small amount of mild soap or toothpaste, but it is not necessary. Avoid using mouthwash or alcohol, as these can degrade the material over time.
- Be sure to scrub all surfaces of the nightguard, including any grooves or indentations, to remove any built-up plaque or bacteria.
- After scrubbing, rinse the nightguard again with cold water to remove any remaining debris or soap residue.
- Allow the nightguard to air dry completely before storing it in its case. Storing the nightguard while it is still damp can promote the growth of bacteria.
By following these steps, you can effectively clean your nightguard with cold water and a toothbrush, ensuring that it remains hygienic and comfortable for nightly use. Remember to also follow any specific care instructions provided by your dentist or the manufacturer of your nightguard.

They should be placed 30 minutes before sleeping
Nightguards are used to protect teeth from the damage caused by teeth grinding or clenching, also known as bruxism. They are typically worn while sleeping, and dental professionals recommend custom-fitted guards for the most comfort and protection.
To get used to sleeping with a nightguard, it is advisable to place it in your mouth at least 30 minutes before going to bed. This allows your mouth to adjust to the guard, helping you fall asleep faster. During this adjustment period, you may experience some mild discomfort and inconvenience, but it will eventually pass.
Wearing the night guard for an extended period before sleeping helps your mouth get accustomed to it. You can also try wearing it during the day for short periods to get used to the feel. It is normal to experience excess saliva during sleep due to the presence of the nightguard, but this typically resolves within two weeks.
To make sleeping with a nightguard more comfortable, ensure that it is properly fitted by a dental professional. Keep the nightguard clean by rinsing it with cold water and scrubbing it with a toothbrush daily. Avoid using hot water, the microwave, or the dishwasher, as heat can cause warping.
Overall, placing the nightguard in your mouth 30 minutes before bedtime is a recommended strategy to help you adjust to wearing it while sleeping. This simple technique can improve your comfort and help you get a good night's rest.

They may cause excess saliva initially
Nightguards are dental appliances used to protect teeth from the damaging effects of teeth grinding or clenching, also known as bruxism. They can be store-bought or custom-made by a dentist, and are typically worn at night since most people grind or clench their teeth during sleep.
While nightguards are effective in preventing teeth from hitting directly against each other and provide a cushioning effect, they may cause some side effects, one of which is excess saliva. This occurs because the presence of something in the mouth stimulates the salivary glands and triggers the body's instinct to produce more saliva. This is a common issue faced by nightguard users, and it can be frustrating and disruptive to sleep.
Excess saliva is often experienced during the initial adjustment period when the body is getting used to the nightguard. On average, it takes about two weeks for the body to adjust, and for the excess salivation to subside. During this time, it is important to be patient and allow the mouth to gradually adapt to the presence of the nightguard.
To minimize the effects of excess saliva, it is recommended to practice breathing through the nose instead of the mouth. This reduces the stimulation of the salivary glands and can help reduce the amount of drooling. Additionally, ensuring a proper fit for the nightguard can also help reduce any discomfort or interference with sleep quality caused by excess saliva.
If the issue of excess saliva persists or becomes a significant concern, it is advisable to consult a dentist or orthodontist for personalized advice and adjustments. They can provide guidance on improving comfort and addressing excessive salivation.
