You may be grinding your teeth without realizing it. Many people clench or grind while sleeping, which means the first signs may be worn enamel, morning jaw soreness, headaches, sensitive teeth, or a dental restoration that repeatedly chips. Over time, the pressure created by nighttime grinding can place unnecessary stress on both natural teeth and dental work.
At AB Dental and Oral Surgery, preventive dentistry in San Antonio includes strategies designed to protect healthy teeth before repeated pressure causes more damage. When teeth grinding or clenching is contributing to excessive wear, a custom nightguard may provide a protective barrier between the upper and lower teeth.
A nightguard does not cure every possible cause of jaw pain or tooth damage. However, for patients with bruxism, it can help manage the effects of repeated tooth-to-tooth pressure while protecting enamel, crowns, fillings, and other restorations.
What Is Bruxism?
Bruxism is the habit of grinding or clenching the teeth. It can happen while a person is awake or during sleep.
Awake clenching may occur during periods of concentration, stress, driving, exercise, or other activities. Sleep bruxism can be more difficult to recognize because the patient is unconscious when it happens.
Some people grind loudly enough that a partner notices. Others clench without producing much sound. In those cases, a dentist may be the first person to recognize patterns of wear or damage associated with excessive pressure.
What Are Signs You May Be Grinding Your Teeth?
Teeth grinding does not affect every patient in the same way. Some people develop obvious tooth wear, while others primarily experience muscle soreness or repeated problems with restorations.
Possible signs include:
- Flattened or worn tooth surfaces
- Small chips along tooth edges
- Morning jaw soreness
- Tight facial muscles
- Headaches after waking
- Tooth sensitivity
- Cracked teeth
- Repeatedly damaged fillings or crowns
- Jaw fatigue
- A partner hearing grinding noises during sleep
These symptoms can have other causes, so an examination is important before assuming bruxism is responsible.
What Is a Custom Nightguard?
A custom nightguard is a dental appliance designed to fit over the teeth while you sleep. It creates a physical barrier between the upper and lower teeth so they are not grinding directly against one another.
The appliance is created using information from your own mouth rather than a generic shape. This allows the nightguard to fit the dental arch more precisely.
Depending on the patient’s bite and needs, the guard may be designed for the upper or lower teeth.
A custom nightguard does not necessarily stop the muscles from attempting to clench. Instead, it helps protect the teeth and restorations from direct contact and can distribute forces more appropriately.
Benefits of a Custom Nightguard
When nighttime grinding is placing excessive pressure on the teeth, a professionally fitted appliance can provide an important layer of protection.
- Protects tooth enamel: A nightguard creates a barrier that reduces direct tooth-to-tooth grinding.
- Helps protect dental restorations: Crowns, fillings, veneers, and other dental work can be exposed to heavy forces from bruxism.
- May reduce morning muscle soreness: Some patients experience less jaw fatigue when damaging contact between teeth is managed.
- Provides a customized fit: The appliance is created from the shape of the patient’s own teeth.
- Helps reduce additional tooth wear: Protecting the chewing surfaces can help limit further grinding-related enamel loss.
- Supports long-term restorative care: Patients who have invested in crowns or other restorations may benefit from protection against excessive bite forces.
How Is a Custom Nightguard Different From a Store-Bought Guard?
Over-the-counter nightguards are usually made in standard sizes or from materials that can be softened and shaped at home. These products may be useful for some people, but they are not created from a professional model or scan of the patient’s teeth.
A custom nightguard is designed according to the individual’s bite and dental anatomy. This can improve fit and stability.
A poorly fitting appliance may feel bulky, move around during sleep, or create uncomfortable pressure. If you have crowns, implants, orthodontic treatment, loose teeth, or significant dental wear, professional evaluation before choosing a guard is particularly important.
Is a Nightguard the Same as a Sports Mouthguard?
No. Although both appliances cover teeth, they are designed for different purposes.
A sports mouthguard is intended to help protect the mouth from sudden impact during athletic activities. A nightguard is designed to manage repeated grinding or clenching forces during sleep.
The material, thickness, fit, and design may therefore differ. Using an athletic mouthguard every night should not automatically be considered a substitute for a professionally recommended nightguard.
Can Teeth Grinding Crack a Tooth?
Repeated grinding and clenching can place substantial pressure on teeth. Over time, this may contribute to enamel wear, small chips, or cracks, particularly when a tooth is already weakened by a large filling or previous damage.
However, cracks can also result from trauma, chewing hard objects, or other causes.
If a tooth hurts when biting or when you release pressure, schedule an examination. A nightguard may help prevent additional stress, but it cannot repair a crack that has already formed.
Can Grinding Damage Dental Crowns and Fillings?
Yes. Dental restorations are designed to tolerate normal chewing forces, but repeated excessive pressure can increase wear.
A filling may chip, a crown may fracture, or bonding material may wear more quickly in a patient who grinds heavily.
When restorative work is repeatedly failing without an obvious explanation, your dentist may evaluate the bite and look for signs of bruxism.
A custom nightguard may then be recommended to help protect both the restorations and the natural teeth supporting them.
Can Grinding Cause Tooth Sensitivity?
Grinding can gradually wear enamel, exposing more sensitive tooth layers. Excessive force can also make the tissues around a tooth feel sore.
However, sensitivity can also result from cavities, gum recession, cracked teeth, damaged fillings, or other conditions.
Do not assume that every sensitive tooth simply needs a nightguard. Identifying the cause first is important so the correct treatment can be recommended.
Can a Nightguard Help With Jaw Pain?
It may help some patients when grinding or clenching contributes to muscle fatigue and excessive pressure.
However, jaw pain has many potential causes, including temporomandibular joint disorders, injuries, dental infections, bite problems, arthritis, and other conditions.
A nightguard should therefore be used as part of a diagnosis rather than as an automatic treatment for every type of jaw discomfort.
Can Stress Cause Teeth Grinding?
Stress and anxiety may contribute to clenching or grinding in some patients, particularly during waking hours. People may notice that they hold their teeth together tightly while working, driving, or concentrating.
A useful daytime habit is to become aware of your resting jaw position. When you are not chewing or swallowing, your teeth generally do not need to remain tightly clenched together.
However, sleep bruxism can involve several factors, so reducing stress alone may not completely eliminate nighttime grinding.
How Is a Custom Nightguard Made?
The dentist first examines the teeth, gums, bite, and existing restorations. Any active dental problems should be identified before an appliance is created.
An impression or digital scan can then capture the shape of the teeth. This information is used to fabricate a nightguard that fits the dental arch.
Once the appliance is ready, the fit and bite are checked. Adjustments may be made so the nightguard seats properly and feels comfortable.
You will also receive instructions for wearing, cleaning, and storing the appliance.
How Long Does a Custom Nightguard Last?
There is no exact lifespan for every nightguard. A patient with heavy grinding may wear through an appliance faster than someone who clenches only occasionally.
The material, design, cleaning habits, fit, and frequency of use can also influence longevity.
Bring your nightguard to routine dental visits so the dentist can inspect it for thinning, cracks, distortion, or changes in fit.
How Should You Clean a Nightguard?
Rinse the appliance after removing it and clean it according to the instructions provided by your dental team. Allowing it to remain covered with saliva and plaque can contribute to odor and buildup.
Store the nightguard in a clean, protective case when it is not being worn. Keep the case ventilated and clean it regularly.
Avoid very hot water unless specifically instructed otherwise, because heat can distort some dental appliance materials.
When Should a Nightguard Be Replaced?
Contact your dentist if the appliance becomes cracked, significantly worn, distorted, loose, or uncomfortable.
You may also need a new nightguard after major dental work changes the shape of your teeth. A new crown, bridge, or other restoration can alter the way an older appliance fits.
Do not force a nightguard into place if it suddenly feels too tight.
Frequently Asked Questions About Custom Nightguards
How do I know if I grind my teeth at night?
Morning jaw soreness, worn teeth, chips, headaches, tooth sensitivity, or a partner hearing grinding noises can be signs. A dental examination can help identify wear patterns.
Will a nightguard stop me from grinding?
A nightguard primarily protects the teeth from direct contact and helps manage grinding forces. It does not guarantee that the muscle activity causing bruxism will stop.
Can I buy a nightguard at a store?
Over-the-counter guards are available, but they do not provide the same individualized fit as a custom dental appliance.
Can a custom nightguard protect crowns?
It can help reduce direct grinding forces on crowns and other restorations, although no appliance can guarantee that dental work will never chip or wear.
Is a sports mouthguard the same as a nightguard?
No. Sports mouthguards are designed for athletic impacts, while nightguards are designed to manage grinding and clenching during sleep.
How often should I replace my nightguard?
Replacement depends on wear, fit, grinding intensity, and changes to your teeth. Your dentist can evaluate the appliance during routine visits.
