Do I need a night guard?
Direct answer
You may need a night guard if you grind or clench your teeth, wake with jaw pain, have worn teeth, cracked fillings, tooth sensitivity, headaches or signs of bite overload. A night guard does not necessarily stop grinding, but it can help protect teeth and restorations from excessive forces. It should be custom-planned after a dental assessment.
Why a custom night guard may help
A night guard creates a protective surface between the teeth during sleep. This can reduce direct tooth-to-tooth wear and protect fillings, crowns and enamel from heavy forces.
The design matters. A poorly fitting or unsuitable appliance can be uncomfortable, affect the bite or fail to protect the right areas.
When a night guard may be considered
| Finding | Why it matters | Possible benefit |
|---|---|---|
| Tooth wear | Grinding can flatten enamel over time. | A guard can reduce further wear during sleep. |
| Cracked fillings or crowns | Restorations may be overloaded. | A guard can distribute forces more safely. |
| Morning jaw pain | Jaw muscles may be overactive at night. | A guard may reduce tooth contact and overload. |
| Tooth sensitivity | Wear, cracks or overload may expose sensitive areas. | Protection may reduce ongoing trauma. |
| TMD symptoms | Jaw pain or clicking may be related to overload. | A guard may be part of a broader treatment plan. |
What should be checked first?
- Tooth wear pattern.
- Cracks in teeth or restorations.
- Jaw muscle tenderness.
- Jaw joint symptoms.
- Bite contacts and tooth position.
- Existing crowns, bridges, implants or veneers.
- Sleep quality, snoring or breathing concerns.
- Dental anxiety, comfort and gag reflex.
What happens at Gloss & Floss Dental Care®?
At Gloss & Floss Dental Care® in Stockholm, we assess whether a night guard is appropriate and what design would suit your teeth, bite and symptoms.
If a guard is recommended, impressions or digital scans may be taken. We also explain how to use, clean and check the appliance over time.
When should you book an assessment?
Book an assessment if you wake with jaw pain, notice worn teeth, break restorations repeatedly or suspect night-time grinding.
Practical advice: Do not rely on an over-the-counter guard long term without diagnosis if you have pain, bite changes or significant tooth wear.
