Teeth grinding: what can a splint do — and what can it not do?

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.

Cleaning a night guard: four practical steps

Bite splints, aligners and retainers can look similar but serve different purposes. A night guard is not worn according to an aligner treatment schedule. Care also depends on the material; follow your individual instructions.

1. Rinse under cold water after removal.
2. Clean with a soft brush. For suitable appliances, the NHS patient leaflet recommends cold soapy water, followed by thorough rinsing. Only use a product recommended for your material.
3. Follow the material instructions for storage and drying. Protect the appliance from heat and keep it out of reach of pets and young children.
4. Contact the practice if there are sharp edges, sore spots, cracks or a change in fit. Do not force a poorly fitting appliance into place or grind it down yourself.
