What is bruxism?
Bruxism involves activity of the chewing muscles, including clenching or grinding the teeth. It can occur during sleep or while awake. Not every episode requires treatment: frequency, intensity and consequences such as pain or damaged teeth matter. The NIDCR bruxism guide describes symptoms and approaches to care.
Awake and sleep bruxism
During the day, you might notice clenching while concentrating, driving or doing stressful work. Recognising the circumstances and learning to relax the jaw can be useful. This does not mean forcing one jaw position all day or monitoring every movement.
Sleep grinding cannot be stopped consciously while it is happening. A partner may hear it, or you may notice morning symptoms. Wear marks alone do not prove that significant sleep bruxism is currently taking place; they may reflect earlier activity or other factors.
Which symptoms should you mention?
- Morning tiredness or soreness in the chewing muscles.
- Clenching noticed during waking hours.
- Grinding reported by someone while you sleep.
- Chipped teeth, broken restorations or sensitivity.
- Jaw pain, restricted movement or locking.
These symptoms have more than one possible cause. Bruxism and temporomandibular disorders, often called TMD, are not the same diagnosis. Headaches should not automatically be attributed to teeth or the bite.
Is stress or an uneven bite the cause?
Several factors may play a role, including stress, individual susceptibility, some medicines and substance use. A single cause cannot be assumed for every person. Mention snoring, pauses in breathing during sleep or daytime sleepiness, as these may need separate assessment.
Straightening teeth cannot be promised to stop bruxism or cure jaw-joint pain. The NIDCR TMD guidance explains concerns about treatment that permanently changes the bite. If orthodontics is needed for another reason, its goals should be discussed separately.
How is it assessed?
Your dentist asks about symptoms and examines teeth, restorations, muscles and jaw movement. Before the appointment, note when symptoms happen, what seems to worsen them and whether someone hears grinding. Bring a medicine list and any splint you already use.
Not everyone needs a sleep study or muscle-activity measurement. Further investigations should answer a question that could change the plan, and another clinician’s input may be appropriate.
What can a dental splint do?
A custom splint may protect teeth and restorations from tooth contact. It cannot guarantee that bruxism will stop or that every cause of pain will resolve. The dentist chooses the design and specifies wear and review.
Do not adjust the splint by filing it yourself. Report new pain, pressure or a change in how the teeth meet. Clean it according to the instructions and bring it to reviews.
Managing the consequences
Care may combine protection of teeth, attention to daytime habits and support with stress. A physiotherapy assessment may be considered for muscle symptoms. Sleep quality, caffeine and alcohol can also be discussed. Do not stop a medicine suspected of contributing without speaking to its prescriber.
If you notice clenching or tooth wear, start with a dental consultation at ProDent. We can assess whether you need protection, further investigation or restoration of damaged teeth, and agree realistic aims for care.
