Sometimes, people who have pain in their jaws, headaches, or sensitivity in their teeth after waking up might also be grinding or clenching their teeth without being aware of it. This popular dental issue, bruxism, is the word given to an individual grinding their teeth. It happens mostly while the person is sleeping and if it continues for a long time, it can lead to very serious damage.
In line with the occasions and conditions we see at Central Coast Smiles, occlusal splints (also called night guards, or bite splints) are often devices that we advise patients to use to safeguard their teeth and to help the jaw to relax when it is in discomfort. This in, depth article will discuss the nature of occlusal splints, the method of treatment with such appliances, the person who requires an occlusal splint, and the steps to be taken in case one decides to undergo the therapy.
What Is an Occlusal Splint?
Basically, an occlusal splint is a custom, fitted, detachable dental device that your dentist makes for you and that you can wear it over your upper or lower teeth. Usually, the patient wears it during the night while sleeping, however, those who tend to clench their teeth while concentrating or being under stress, might wear it during the day as well.
The splint acts as a protective shield between your teeth. By doing so, it prevents the damage caused by the grinding and clenching forces and at the same time, it helps in achieving a more balanced jaw position.
Occlusal splints are sometimes referred to as:
- Night guards
- Dental splints
- Bite splints
- Bruxism guards
While the names may vary, the goal is the same to protect your teeth and reduce strain on your jaw muscles and joints.
Why Do People Need a Splint?
Many people grind or clench their teeth without being aware of it. Bruxism commonly occurs during sleep, meaning you cannot consciously stop it.
Over time, this excessive pressure can lead to:
- Flattened or worn-down teeth
- Chipped or cracked teeth
- Fractured fillings or crowns
- Tooth sensitivity
- Jaw pain and stiffness
- Tension headaches
- Facial muscle soreness
- Clicking or discomfort in the jaw joint
If left untreated, bruxism can cause irreversible damage to your teeth and contribute to temporomandibular joint (TMJ) dysfunction.
An occlusal splint helps manage these risks by absorbing pressure and guiding your jaw into a more neutral resting position.
How Does an Occlusal Splint Work?
An occlusal splint works in several important ways:
- Protects Tooth Surfaces
When you grind your teeth, the enamel (outer layer) can wear down. The splint acts as a shield, taking the force instead of your natural teeth.
- Reduces Muscle Strain
Clenching places heavy pressure on jaw muscles. A splint can help relax these muscles by slightly adjusting the way your teeth meet.
- Supports Jaw Joint Health
The temporomandibular joints (TMJ) connect your jaw to your skull. Grinding and clenching can overload these joints. A splint helps distribute pressure more evenly and reduce stress on the joints.
- Helps Prevent Further Damage
While a splint does not necessarily stop bruxism completely, it significantly reduces the damage it can cause.
Signs You May Need a Night Guard
Your dentist may detect signs of bruxism during a routine examination. However, you may also notice symptoms yourself, including:
- Morning jaw soreness
- Headaches upon waking
- Teeth that feel sensitive or tender
- Difficulty opening your mouth fully
- Clicking or popping in your jaw
- Teeth that appear shorter or worn
If you experience any of these symptoms, it is worth discussing them with your dentist.
What Is the Process for Getting a Splint?
Getting a custom occlusal splint usually involves two appointments.
First Appointment Records and Impressions
Your dentist will take digital scans or impressions of your teeth. This ensures the splint is precisely tailored to your mouth.
Laboratory Fabrication
The impressions are sent to a dental laboratory, where skilled technicians create your custom splint.
Second Appointment Fitting and Adjustment
Once ready, your dentist will check the fit and make any necessary adjustments to ensure comfort and proper function. You will also receive instructions on how to wear and care for it.
What Does It Feel Like to Wear One?
When you first start wearing your splint, it may feel slightly unusual or bulky. This is completely normal.
Some patients notice:
- A tight sensation at first
- Increased saliva production
- Mild discomfort for the first few nights
Most people adjust quickly within a few days to a couple of weeks. Many patients eventually report they sleep better and feel more comfortable wearing their splint than without it.
If your splint causes persistent pain or does not feel right, it is important to contact your dentist for review.
How Long Does a Splint Last?
The lifespan of an occlusal splint depends on:
- How often you wear it
- How intensely you grind
- How well you maintain it
On average, splints may last between 2–3 years. Heavy grinders may need replacement sooner, while mild cases may last longer.
Regular dental check-ups allow your dentist to monitor wear and ensure your splint continues to fit correctly.
How Do You Care for a Night Guard?
Proper care is essential to keep your splint hygienic and long-lasting.
We recommend:
- Rinsing with cool water before and after use
- Cleaning gently with a soft toothbrush
- Avoiding hot water (which can warp the material)
- Storing it in its protective case
- Keeping it out of reach of pets
Bring your splint to your dental appointments so it can be checked professionally.
What If My Splint Stops Fitting?
Teeth can shift slightly over time, especially if you have had dental treatment such as fillings or crowns.
If your splint feels:
- Too tight
- Loose
- Painful
- Impossible to insert
Do not attempt to adjust it yourself. Book an appointment so your dentist can assess and modify it safely.
Are Over-the-Counter Guards Safe?
While pharmacy night guards may seem like a cheaper alternative, they are not custom-fitted and may:
- Fit poorly
- Cause bite changes
- Increase jaw discomfort
- Fail to protect your teeth adequately
A professionally made splint is designed specifically for your bite and provides more reliable protection.
Does a Splint Cure Bruxism?
An occlusal splint is not a cure for bruxism. Rather, it helps to deal with the consequences by shielding your teeth and lessening the tension in your jaw.
Bruxism is related to stress, sleep disorders, or bite imbalances. Sometimes, other therapies may be suggested with the use of a splint.
Final Thoughts
Grinding and clenching may impact your teeth severely and permanently if you don’t do anything about it. An occlusal splint is a great, non, invasive method to help keep your teeth safe, ease pain, and maintain oral health in the long run.
In case you think that you grind your teeth or have symptoms like jaw pain, headaches, and worn, out teeth, consult your dentist about a custom night guard option.
