Why Would a Dentist Recommend a Bite Splint?

Waking up with a sore jaw, headaches, or worn-down teeth can be confusing if you're not sure what's causing it. Many people don't realise these symptoms are often linked to teeth grinding or clenching, especially during sleep, and may go on for months before being noticed.

A dentist may recommend a bite splint to help manage these issues. A bite splint, sometimes called a night guard or occlusal splint, is a custom-made device worn over the teeth, designed to fit your bite based on an impression or scan taken at the clinic.

This article is provided by IDD Dental Lab, a dental laboratory based in New Zealand that manufactures custom dental appliances, including bite splints, for dental practices and their patients. While we work closely with dentists to craft devices tailored to each patient's bite, we do not provide clinical diagnosis or treatment advice. 

The information here is intended for general educational purposes only. If you're experiencing symptoms such as jaw pain, headaches, or tooth wear, please speak with your dentist, who can assess your individual situation and determine whether a bite splint or other treatment may be appropriate for you. 

What Is a Bite Splint?

A bite splint is a removable appliance, usually made from durable plastic or acrylic, designed to fit snugly over your upper or lower teeth.

It creates a smooth surface between your top and bottom teeth, reducing direct contact during grinding or clenching episodes. This helps protect the tooth surfaces from gradual wear that can build up over time.

Bite splints are typically custom-fitted based on a mould or digital scan of your teeth, with the appliance crafted by a bite splint dental lab in New Zealand to support a comfortable and secure fit for each individual patient. A well-fitted splint sits comfortably without feeling bulky, allowing for normal speech and a more restful night's sleep for many people.

Your dentist will discuss which type of splint may suit your needs during a consultation, based on an assessment of your bite and overall oral health.

Types of Bite Splints

There are different styles of splints, including soft, hard, and dual-laminate designs. The right type depends on the severity of grinding and individual jaw needs, which a dentist can assess during a consultation.'

Common Reasons Dentists Recommend Bite Splints

Managing Teeth Grinding (Bruxism)

Many people grind or clench their teeth without realising it, often during sleep. Over time, this can wear down enamel and increase tooth sensitivity.

A bite splint creates a barrier between the teeth, which may help reduce the impact of grinding forces.

Easing Jaw Discomfort

Clenching and grinding can place extra strain on the jaw joints and surrounding muscles. Some people experience tension headaches, facial soreness, or difficulty opening their mouth comfortably.

A splint may help by encouraging a more relaxed jaw position during sleep.

Protecting Dental Work

If you have crowns, veneers, fillings, or other restorations, grinding can place extra pressure on these surfaces.

A bite splint can act as a protective layer, helping to reduce wear on both natural teeth and dental restorations.

Supporting TMJ-Related Concerns

Temporomandibular joint (TMJ) issues can cause clicking sounds, jaw stiffness, or discomfort while chewing.

While a splint isn't a cure, it may form part of a broader approach to managing TMJ-related symptoms, alongside other guidance from your dental team.

How a Bite Splint Is Made

Creating a bite splint usually involves a few simple steps. First, your dentist takes an impression or digital scan of your teeth.

This information is then sent to one of the dental labs in NZ, where the splint is custom-made to closely match your bite using the measurements provided.

Once ready, your dentist will check the fit and make small adjustments if needed, helping the splint sit comfortably and function as intended. 

What to Expect When Wearing a Bite Splint

It's common to need a short adjustment period when you first start wearing a splint. Your mouth may feel slightly different initially, but most people adapt within a week or two.

Regular check-ups allow your dentist to monitor how the splint is working and make adjustments if your bite changes over time.

Caring for your splint properly, including regular cleaning, may help support hygiene and may help extend its lifespan. 

Frequently Asked Questions

How do I know if I need a bite splint?

Signs such as jaw pain, headaches upon waking, or noticeably worn teeth may indicate grinding. Some people also notice tooth sensitivity or a clicking sound in the jaw joint. A dental check-up can help determine whether a splint may be suitable for your situation, based on an examination of your teeth and bite. 

Is wearing a bite splint uncomfortable?

Most people find that any initial discomfort settles within a short adjustment period, as the mouth gets used to the new sensation. A well-fitted splint should feel comfortable once you become used to wearing it, without affecting normal breathing or speech. 

How long does a bite splint last?

The lifespan of a splint depends on factors such as material, grinding intensity, and care routine. With proper dental cleaning and storage, splints may last for some time, though this can vary and wear may appear sooner in cases of heavy grinding. Your dentist can advise on when a replacement may be needed. 

Can children wear bite splints?

In some cases, a dentist may consider a splint for a child experiencing grinding, depending on their individual dental development and the underlying cause. This would be assessed on a case-by-case basis, taking into account the child's age and growth stage. 

Conclusion 

Bite splints are a common recommendation for people experiencing teeth grinding, jaw discomfort, or wear on their teeth and dental restorations. They are designed to sit comfortably over the teeth, creating a barrier that may help reduce the impact of clenching during sleep.

While outcomes vary depending on individual circumstances, some patients find a custom-fitted splint comfortable and helpful as part of their oral health routine. A comfortable, well-fitted splint may be more likely to be worn regularly, which can support its effectiveness. 

If you're experiencing jaw pain, headaches, or notice changes in your teeth, it's worth discussing your symptoms with your dentist. A personalised treatment plan, including whether a splint made through IDD Dental Lab might suit your needs, can be discussed during your consultation, along with guidance on care and what to expect.
