Teeth Grinding (Bruxism) Treatment in London: Causes and Options
Teeth grinding — known clinically as bruxism — is more common than most people realise, and more damaging than many expect. It often happens during sleep, which means patients are frequently unaware of it until a dentist identifies characteristic wear patterns on the teeth, or until symptoms such as jaw pain, morning headaches or tooth sensitivity become noticeable.
Left untreated, bruxism can cause significant and irreversible damage to the tooth surfaces, jaw joints and muscles — and can compromise dental restorations including veneers, crowns, fillings and implants. This guide explains what bruxism is, how it is recognised, what treatment options are available in London and what to consider before choosing an approach.
Bruxism is the involuntary clenching or grinding of teeth, most commonly during sleep (sleep bruxism) but also during waking hours (awake bruxism). It can exert forces on teeth far greater than normal chewing — sufficient to flatten, chip or crack tooth enamel over time and to cause significant jaw muscle and joint symptoms.
Signs and Symptoms of Bruxism
Many patients with bruxism do not know they grind their teeth until a dentist points out the signs during a routine examination. The following are common indicators that should prompt a clinical assessment:- Worn, flattened or shortened tooth surfaces — particularly on the biting edges of front teeth or the chewing surfaces of back teeth
- Chipped, cracked or sensitive teeth without an obvious cause
- Jaw pain, stiffness or clicking — particularly in the morning
- Headaches on waking, often felt at the temples
- Facial muscle tension or tenderness, especially around the jaw and cheeks
- Earache without any evidence of ear infection
- A partner or family member reporting grinding sounds during sleep
- Loose or damaged dental restorations — fillings, crowns or veneers that repeatedly fracture or come loose
What Causes Bruxism?
The exact cause of bruxism is not fully established, and in many cases multiple factors contribute. Stress and anxiety are among the most commonly associated factors — the jaw muscles can hold tension during sleep in the same way they do during periods of emotional strain. Sleep disorders, including sleep apnoea, are also associated with higher rates of sleep bruxism. Bite misalignment — where the upper and lower teeth do not meet evenly — can be a contributing factor in some patients, though it is not considered the primary cause in most cases. Lifestyle factors including high caffeine intake, alcohol consumption and certain medications have also been associated with bruxism. Understanding the likely contributors for each patient helps guide the most appropriate treatment approach.How Is Bruxism Diagnosed?
Bruxism is usually identified during a routine dental examination. The dentist examines the teeth for characteristic wear patterns, assesses the bite, checks the jaw joints and muscles, and takes a full history of symptoms. There is no single definitive test for bruxism — diagnosis is based on clinical signs, patient history and, where relevant, a sleep study if a sleep disorder is suspected. The degree of tooth wear and any symptoms guide the urgency and type of treatment needed. Mild wear with no symptoms may require monitoring and a preventive night guard. More advanced wear or significant jaw symptoms may need a more comprehensive management approach.Treatment Options for Bruxism in London
Custom Night Guard (Occlusal Splint)
A custom-made night guard — also called an occlusal splint — is the most commonly recommended first-line treatment for sleep bruxism. It is a hard or soft acrylic device worn over the upper or lower teeth during sleep. It does not stop the grinding reflex, but it protects the tooth surfaces and reduces the forces transmitted to the jaw joints and muscles. At DentAkademi London, a custom night guard or gum shield is available from £350. This is made from impressions of the teeth for a precise fit — unlike over-the-counter boil-and-bite alternatives, which provide less accurate protection and can affect the bite if not fitted correctly. A well-fitted night guard should be comfortable enough to wear consistently every night.Botulinum Toxin (BTX) Injections
Botulinum toxin injections into the masseter muscles — the large chewing muscles on either side of the jaw — can reduce the force of clenching in selected patients. By partially relaxing the masseter, the force exerted during grinding is reduced, which can alleviate jaw pain, headaches and tooth wear. At DentAkademi London, BTX for one area is available from £195. Results typically last three to six months, after which repeat treatment is needed to maintain the effect. BTX for bruxism does not permanently stop grinding — it reduces its intensity. It is generally used alongside a night guard, not as a standalone replacement for tooth protection. Over time, some patients notice a reduction in masseter muscle bulk, which can also subtly change the facial profile by softening the jawline.Orthodontic Treatment
Where bite misalignment is a significant contributing factor to bruxism, orthodontic treatment may be considered to improve the occlusion. Correcting how the upper and lower teeth meet can reduce uneven biting forces and may help with symptoms in some patients. However, orthodontics is not a treatment for bruxism itself, and a night guard is usually recommended alongside any orthodontic correction to protect the teeth and the result.Stress Management and Lifestyle Adjustments
Where stress or anxiety is a clear contributing factor, addressing these underlying causes can reduce bruxism severity. Cognitive behavioural therapy, relaxation techniques and sleep hygiene improvements have shown benefit in some patients. Reducing caffeine and alcohol, particularly in the evening, may also help. These approaches are often most effective when combined with a night guard rather than used alone.Bruxism and Dental Damage: What Is at Risk
The forces generated by bruxism can be considerably greater than those of normal chewing. Over years, this can flatten the biting edges of front teeth, reduce tooth height, cause surface cracking, increase sensitivity, and lead to problems with the jaw joints (temporomandibular joints). Patients who have had restorative or cosmetic dental work are also at risk — fillings, crowns, veneers and bridges can all be damaged or dislodged by persistent grinding.Bruxism and Veneers or Implants
Patients who grind their teeth and are considering porcelain veneers, crowns or dental implants need to have their bruxism managed before treatment begins. Uncontrolled grinding significantly increases the risk of veneer fracture, crown failure and, in the case of implants, peri-implant bone stress. A night guard is strongly recommended before and after any significant restorative or cosmetic dental work for patients with a known history of bruxism. This does not mean veneers or implants are impossible — many patients with well-controlled bruxism have successful long-term outcomes. But it does mean the grinding needs to be acknowledged and planned for, not ignored.Over-the-counter night guards from pharmacies are not equivalent to custom-made dental splints. Ill-fitting guards can shift the bite, cause discomfort and may not provide adequate protection. If you suspect you grind your teeth, a dental assessment before purchasing any device is the most reliable starting point.
Can Bruxism Be Cured?
There is no single cure for bruxism. For most patients, management focuses on reducing its effects — protecting the teeth with a night guard, alleviating symptoms with BTX or physiotherapy, and addressing contributing factors where possible. Some patients find that bruxism reduces significantly during periods of lower stress, or as sleep improves. For others, it is a long-term condition requiring ongoing management rather than a one-time fix. The most important thing is to identify and manage bruxism before significant tooth structure is lost — enamel cannot regenerate, and the damage caused by years of untreated grinding can require extensive and costly restorative treatment to address.Frequently Asked Questions
What is bruxism?
Bruxism is the involuntary clenching or grinding of teeth, most commonly during sleep. It can cause significant tooth wear, jaw pain, headaches and damage to dental restorations if left unmanaged.What are the signs of teeth grinding?
Common signs include worn or flattened teeth, chipped or sensitive teeth, jaw pain or clicking, morning headaches, facial muscle tension and a partner reporting grinding sounds during sleep. A dentist can identify wear patterns during examination.What causes bruxism?
Contributing factors include stress and anxiety, sleep disorders, bite misalignment and lifestyle factors such as caffeine and alcohol. In most cases, several factors are involved rather than a single cause.How is bruxism treated in London?
Treatment options include a custom night guard to protect teeth, botulinum toxin injections to reduce jaw muscle force, orthodontic correction where bite misalignment contributes, and lifestyle or stress management approaches. Most patients benefit from a combination.How much does a night guard cost in London?
At DentAkademi London, a custom-made night guard is available from £350. This is laboratory-made from impressions of your teeth for an accurate, comfortable fit.Can botulinum toxin help with teeth grinding?
BTX injections into the masseter muscles can reduce clenching force and help manage bruxism symptoms. At DentAkademi London, BTX for one area is from £195. Results last three to six months and repeat treatment is needed to maintain the effect.Does bruxism damage teeth permanently?
Yes — untreated bruxism can cause irreversible enamel loss, chipping, cracking, sensitivity and damage to restorations. Enamel cannot regenerate, so early management is important to prevent long-term damage.Can orthodontic treatment help with bruxism?
Where bite misalignment is a contributing factor, orthodontics may help by improving the occlusion. However, it does not treat bruxism itself — a night guard is usually still needed alongside orthodontic treatment.Can I have veneers or implants if I grind my teeth?
Yes, but bruxism should be managed first. A night guard before and after veneer or implant treatment significantly reduces the risk of fracture or failure. Uncontrolled grinding is one of the most common causes of cosmetic and restorative dental work failing prematurely.What is the first step for bruxism treatment at DentAkademi London?
Book a dental consultation at £50. The dentist will assess tooth wear, jaw symptoms and contributing factors, and provide a written treatment plan before any treatment begins.
