Teeth grinding: what can a splint do — and what can it not do?
Perhaps someone has heard you grinding your teeth at night. Or you notice yourself clenching while concentrating on work. Both can be part of bruxism. The term describes chewing muscle activities that can occur during sleep or while awake. Whether treatment is needed depends on their effects. Occasional activity is not automatically a disorder.

Editorial review:
01 Myth 1: People who grind their teeth notice it themselves
Not necessarily. Night-time grinding in particular is sometimes first noticed by someone else. Possible signs include strained chewing muscles, sensitive teeth or visible wear. On their own, however, these signs do not prove a particular cause. During the examination, your observations are considered alongside the condition of your teeth and chewing muscles. NIDCR: Bruxism
You can prepare for the discussion without constantly monitoring your jaw: briefly note when you notice symptoms or clenching. For example, in the morning, while driving or during focused screen work. It is also useful to know whether symptoms are new or have been similar for some time. The note is intended to help you describe your observations — it is not a self-test with a result.
02 Myth 2: A splint stops grinding
An occlusal splint can protect tooth surfaces from direct contact and further mechanical stress. However, this does not mean it permanently eliminates the underlying muscle activity. The current guideline therefore distinguishes protection from consequences from treatment of the activity itself. The role of a splint depends on the findings and treatment aim. S3 guideline: Diagnosis and treatment of bruxism
A useful question is: “What specifically is the splint intended to achieve for me?” Is it about protecting teeth under strain, managing symptoms or several aspects? Also discuss when its effect and fit should be checked. This keeps the basis for ongoing care clear. If you already have a splint, you can bring it to the appointment and describe your experience so far. Questions about cleaning belong in this discussion too.
03 Myth 3: Teeth grinding always means stress
Stress can play a role, but it is not the only possible influence. Bruxism has several associations; sleep, certain recreational substances and some medicines may also be relevant to assessment. Medicines should therefore be mentioned during the discussion, but not changed or stopped on your own initiative. NIDCR: Causes and influences
Depending on the situation, other disciplines may be useful alongside dental care. The government research institution NIDCR mentions physiotherapy, support with managing stress or sleep medicine assessment, for example. This does not establish a standard treatment for everyone affected. NIDCR: Questions for a bruxism expert
04 What can be discussed about everyday life?
Mention situations you recognise and what already helps you. Ask to be shown suitable, simple measures rather than trying jaw exercises indiscriminately. A splint, a changed habit and an additional assessment serve different purposes. A personal discussion can turn these into a manageable next step.
