Teeth grinding and jaw clenching
Grinding and clenching can happen during sleep or while awake, and many people are unaware of it. Often the first sign is what it leaves behind: worn teeth, cracked fillings or an aching jaw.
Signs we look for
- Flattened, chipped or more sensitive teeth
- Cracked fillings, failing crowns or fractured teeth
- Waking with headaches or an aching jaw
- A partner noticing grinding noises at night
- In some cases, damage extensive enough that restorative work is discussed
Not all tooth wear comes from grinding. Diet, acid reflux and other factors can also contribute, so an examination looks at the pattern of wear rather than assuming a cause.
Understanding the cause
The causes of bruxism are not fully understood and often more than one factor is involved. Stress, certain medicines and sleep-related breathing problems have all been associated with it, and their relative importance differs from person to person.
We examine the wear pattern on your teeth, the jaw joints and surrounding area, and your medical and dental history. Where the pattern suggests a sleep-related breathing problem, we would discuss referral for medical assessment rather than treating it here.
What may be discussed
- A custom-made night splint, worn to help protect the teeth from further wear
- Reviewing contributing factors identified during the assessment
- Referral for medical assessment where sleep-related breathing problems are suspected
- Repair of teeth already damaged, where that is appropriate
A splint is intended to help protect teeth from wear; it does not stop grinding itself. Which approach suits you depends on your individual assessment, and outcomes vary between people. We will talk through the options, their limitations, risks and alternatives before anything is decided.
