Night Guards for Teeth Grinding

Night Guards and Michigan Splints in Notting Hill

Teeth grinding and clenching, sometimes known as bruxism, can place significant pressure on the teeth, jaw joints and surrounding muscles. Many people grind during sleep without realising it until symptoms develop or wear becomes visible.

At Keep Smiling Dental Practice on Westbourne Grove, we provide custom-made night guards and Michigan splints for patients in Notting Hill, W11 and surrounding West London areas. These appliances are designed to help protect teeth and restorations from excessive grinding forces while supporting bite comfort.

A Michigan splint is not a location-based treatment. It is a type of professionally designed occlusal splint used to help manage grinding, clenching and bite-related strain.

The purpose is not necessarily to stop grinding completely. Instead, the appliance helps reduce damaging contact and distribute bite forces more evenly.

Night Guards, Crowns and Restorative Dentistry

Night guards often work alongside wider restorative dentistry. Patients with crowns, white fillings, implants or worn teeth may benefit from bite protection to help reduce stress on restorations.

This is particularly relevant where tooth wear or clenching is contributing to repeated damage or restorative failure. Preventive protection may support long-term maintenance and reduce avoidable repair work.

Night guards may also form part of smile makeover planning or restorative treatment where bite forces influence long-term outcomes.

Bruxism, Tooth Wear and Bite Pressure

Bruxism is the clinical term used to describe grinding or clenching of the teeth. It may happen during sleep or while awake and can place repeated pressure on the teeth, jaw joints and surrounding muscles.

Some patients become aware of bruxism through jaw tension, headaches or tooth sensitivity, while others only discover it during a dental examination when wear patterns become visible. Flattened biting edges, chipped enamel, fractured fillings or muscle tenderness may all suggest grinding activity.

Grinding does not affect everyone in the same way. Some patients experience mild wear, while others develop more significant damage to natural teeth or restorations over time. Identifying these patterns early allows treatment to focus on prevention and protection rather than later repair alone.

Custom Night Guards Compared with Shop-Bought Guards

Over-the-counter mouth guards and boil-and-bite appliances are widely available, but they are not designed specifically around your bite. While they may offer temporary cushioning, they often lack the precision and balance of a professionally made appliance.

A custom-made night guard or Michigan splint is planned around the shape of your teeth and the way your bite functions. This individual fit is important because uneven pressure or poor adaptation may reduce comfort and compromise the intended protective effect.

Custom appliances are also easier to review and adjust over time. Your dentist can assess wear patterns, monitor symptoms and ensure the appliance continues to fit properly as part of ongoing maintenance.

The goal is not simply to provide something to bite on. It is to create a professionally planned protective appliance that supports comfort, stability and long-term dental health.

Jaw Tension, Muscle Fatigue and Bite Health

Grinding and clenching can affect more than the teeth alone. Some patients notice jaw tightness, facial muscle fatigue or morning discomfort related to overnight bite pressure.

A night guard is not a cure for every form of jaw or facial pain, and symptoms can have several causes. However, where grinding and bite-related strain are contributing factors, protective appliances may help reduce pressure and support greater comfort.

Assessment remains important because symptoms affecting the jaw joints, muscles or bite should be reviewed properly rather than self-diagnosed or managed with generic appliances alone.

Maintaining and Replacing a Night Guard

Like any dental appliance, night guards and Michigan splints require maintenance. Wear marks on the appliance often reflect the forces that would otherwise be affecting your teeth and restorations.

Cleaning the appliance regularly and storing it correctly helps maintain hygiene and fit. During review appointments, we check the appliance, assess the bite and determine whether adjustments or replacement may be needed.

The lifespan of a night guard depends on the intensity of grinding, the design of the appliance and how well it is maintained. Patients with stronger clenching patterns may wear through appliances more quickly and require periodic review.

How Night Guards Help Protect Teeth

Grinding forces can place stress on enamel, fillings, crowns and other restorations. Over time this may contribute to wear, cracking and bite changes.

A professionally made night guard is designed to fit your teeth accurately and provide a controlled protective surface. This differs from generic over-the-counter guards, which may not fit precisely or provide balanced support.

Custom appliances can also support patients with crowns, implants or previous restorative work where protection from excessive bite forces is important.

How Treatment Works

1. Assessment. Review of symptoms, wear and bite function.
2. Planning. Discussion of appliance suitability and design.
3. Impressions or scans. Records used to create the appliance.
4. Fitting. Appliance adjusted for comfort and bite balance.
5. Review. Monitoring and maintenance advice.

Signs You May Need a Night Guard

• Grinding or clenching during sleep.
• Worn, flattened or chipped teeth.
• Jaw discomfort or morning tension.
• Tooth sensitivity linked to wear.
• Frequent damage to fillings or crowns.
• Awareness of bite pressure or clenching habits.

Many patients are unaware of nighttime grinding until it is noticed during a dental examination or highlighted by a partner or family member.

What Is a Michigan Splint?

A Michigan splint is a type of hard acrylic bite appliance commonly used in restorative and occlusal dentistry. It is custom-made to fit your bite and is designed to help manage grinding and muscle-related bite strain.

The appliance is planned around your teeth and jaw relationship rather than being supplied as a generic device. This individual planning helps improve comfort and support.

Your dentist will explain whether a Michigan splint or another form of protective appliance is most suitable for your situation.
