A custom night guard or bite splint protects your teeth, and every good option is metal-free. Learn the difference between soft, hard and dual-laminate guards, why splint design matters for the jaw joint, when to screen for sleep apnea, and what custom splints cost in Tijuana.* **Source:** [https://www.molarcity.com/night-guard-bite-splint-bruxism/](https://www.molarcity.com/night-guard-bite-splint-bruxism/) ![cover](https://www.molarcity.com/fotosarticulos/night-guard-bite-splint-bruxism.webp) Many people grind or clench their teeth during sleep without knowing it. The first clue is often a partner hearing the noise, a sore jaw in the morning, headaches at the temples, or a dentist pointing out flattened, chipped teeth. This habit, called **bruxism**, can also crack fillings and crowns, and it is one of the most common reasons expensive dental work fails. This guide from Molar City, an independent dental tourism platform since 2007, explains how night guards and bite splints work and which materials make sense for patients who prefer a metal-free, biocompatible mouth. ## Night guard vs bite splint: the difference The terms overlap. A **night guard** usually means a protective cover worn while sleeping. A **bite splint** or **occlusal splint** is a custom appliance whose biting surface is carefully adjusted so the jaw muscles can relax and the bite is balanced. A well-made splint does both: it protects teeth and distributes forces evenly. ## Types and materials Virtually all custom night guards are metal-free. The differences are in hardness, comfort and durability: TypeMaterialProsCons Soft guardFlexible thermoplastic (EVA or similar)Comfortable, inexpensiveCan encourage chewing in some grinders; wears quickly Dual-laminateSoft inner layer, hard outer layerComfortable fit with a durable surfaceThicker; harder to adjust Hard acrylic splintHeat-processed or milled PMMAMost durable, precisely adjustable, recommended for heavy bruxism and jaw painRequires accurate fabrication and follow-up adjustments Over-the-counter boil-and-biteThermoplasticCheap, immediatePoor fit, can alter the bite if worn long term Patients concerned about BPA sometimes ask about plastics. PMMA acrylic is not made from BPA, unlike polycarbonate. If you have material sensitivities, ask the clinic which resin they use and whether it is heat-processed or milled, which typically leaves less residual monomer than cold-cured acrylic. ## Why splint design matters - **Full coverage:** covering all teeth in one arch avoids unwanted tooth movement. Small anterior-only devices can be useful short term but should be supervised. - **Even contacts:** the opposite teeth should touch the splint evenly, with smooth guidance when you slide your jaw. - **Follow-up:** hard splints usually need one or two adjustment visits as the muscles relax. A splint protects your teeth and can reduce muscle strain, but it does not cure bruxism. Stress, caffeine, alcohol, some medications and sleep disorders can all contribute. ## Bruxism and sleep apnea Night-time grinding is sometimes linked to disrupted breathing during sleep. If you snore loudly, wake unrefreshed or have daytime sleepiness, ask your physician about sleep apnea screening before relying on a night guard alone. In some cases a different device, a mandibular advancement appliance, prescribed after a sleep study, is more appropriate. Do not treat suspected sleep apnea with a night guard without medical evaluation. ## Protecting new dental work If you are investing in ceramic crowns, onlays or implants, a night guard is inexpensive insurance. Even strong materials can chip under grinding forces. Many dentists recommend a splint after placing [same-day ceramic crowns](https://www.molarcity.com/same-day-cerec-crowns-mexico/), [inlays and onlays](https://www.molarcity.com/inlays-onlays-vs-crowns-replacing-amalgam/) or [metal-free crowns](https://www.molarcity.com/metal-free-crowns-zirconia-emax-porcelain/), and for implants, where there is no natural ligament to cushion forces. ## Cost in Tijuana vs the USA In Tijuana, the biological clinic [American Biodental Center](https://www.molarcity.com/american-biodental-center/dentists-in-tijuana-mexico/), founded in 1998 with an in-house lab, **publishes** these prices. US figures are typical ranges.

Consult your dentist about the right appliance for your bite and symptoms, and your physician if you suspect a sleep disorder. ## Signs you may be grinding at night - Jaw tightness, soreness or clicking when you wake up. - Dull headaches at the temples, especially in the morning. - Teeth that look shorter, flat or chipped at the edges. - Sensitivity to cold caused by worn enamel or small cracks. - Scalloped edges on the sides of the tongue or ridges on the inner cheeks. - A partner who hears grinding sounds during the night. Daytime clenching is also common, especially when concentrating or stressed. A night guard does not address it, but awareness helps: many dentists suggest checking during the day that your lips are together and your teeth apart, with the jaw relaxed. If symptoms persist, a dentist can evaluate the jaw joint and muscles before making a splint. ## Frequently asked questions ### Are custom night guards metal-free? Yes. Custom night guards and bite splints are made from acrylic or thermoplastic resins and contain no metal. ### Is a hard or soft night guard better for grinding? For heavy grinding or jaw pain, dentists usually recommend a hard acrylic splint because it is durable and can be precisely adjusted. Soft guards are more comfortable but wear faster and may not suit heavy grinders. ### How long does a custom bite splint last? A hard acrylic splint typically lasts three to ten years depending on how much you grind. Soft guards may need replacing every six to twelve months. ### Can a night guard stop bruxism? No. It protects teeth and can reduce muscle strain, but it does not eliminate the habit. Managing stress, reviewing medications and screening for sleep disorders address underlying causes. ### How much does a bite splint cost in Tijuana? American Biodental Center publishes $300 for a custom bite splint, compared with roughly $400 to $1,000 for a lab-made splint in the United States. ## Frequently Asked Questions ### What is the difference between a night guard and a bite splint? A night guard is a removable oral appliance that cushions teeth from grinding and clenching. A bite splint is designed with specific bite and jaw-joint considerations, so splint design matters for the TMJ. Both protect teeth, but a properly designed splint also addresses jaw position and strain. ### Are metal-free night guards available? Yes. Every good night guard or bite splint option is metal-free, so you do not have to worry about metal components. Choices include soft, hard, and dual-laminate guards. ### Should I be screened for sleep apnea if I grind my teeth? Yes. Bruxism can be linked to sleep apnea, so screening is important. A dentist can help identify whether a sleep study or further evaluation is needed before choosing an appliance. ### What types of night guards can I choose from? The main options are soft guards, hard guards, and dual-laminate guards. Soft guards are comfortable, hard guards are durable, and dual-laminate guards combine a soft inner layer with a hard outer layer. ### Why does splint design matter for the jaw joint? A splint that is not designed for your bite can strain the jaw joint instead of relieving it. Proper design helps position the jaw comfortably and reduces strain on the TMJ. ### Can I get a custom night guard in Tijuana? Yes, custom splints are available in Tijuana. Because pricing varies by provider and appliance type, ask your dentist for a specific quote rather than relying on general estimates. ## Questions this page answers - how much does a custom night guard cost in Tijuana - best night guard for teeth grinding - metal-free bite splint for bruxism - soft vs hard night guard which is better - night guard for TMJ jaw pain - can a night guard help sleep apnea - dentist in Tijuana for night guard - custom bite splint cost Mexico - do I need a night guard if I grind my teeth - affordable night guard for Americans in Mexico --- ## More on MolarCity - [Homepage](https://www.molarcity.com/) - [Verified Dentists](https://www.molarcity.com/dentists-in-los-algodones-molar-city-mexico.php) - [Price List](https://www.molarcity.com/price-list-in-los-algodones.php) - [llms.txt index](https://www.molarcity.com/llms.txt) --- ## Citation & licence - **Publisher:** Molar City Group S.A. de C.V. - independent dental-tourism platform, operating since 2007.
