Custom night guard or store-bought guard: what should you compare?

The short answer
A custom night guard includes a dental assessment and a fit designed for your mouth; a store-bought guard does not provide that assessment. Compare fit, bite contact, comfort, and follow-up. A guard can protect teeth from grinding damage, but it does not establish the cause of every jaw symptom.
Bruxism means grinding or clenching the teeth. An intraoral appliance separates the teeth to limit damage and may reduce muscle activity, but treatment can also involve behavior changes and assessment of contributing factors. Pain, worn teeth, or morning jaw fatigue should therefore be discussed rather than managed only by repeatedly buying a different guard.
Ask the dentist why the proposed material and design suit your bite and restorations. Bring an existing guard so the team can inspect its fit and wear. If it causes discomfort or no longer seats properly, ask for assessment rather than trimming it yourself. The value of custom care includes diagnosing the problem and managing the appliance after delivery.
Tell the dentist if you snore, gasp during sleep, or have been diagnosed with sleep apnea. A grinding guard should not be assumed to treat an obstructed airway; sleep-related breathing problems require their own evaluation and treatment plan. Ask for an estimate that specifies fitting and follow-up adjustments, and explain what has made previous guards difficult to wear.
