“Both. It is a single, custom-made device that works as a night guard (protects your teeth from grinding wear) and as a retainer (holds your teeth in their current position). It is a thin, hard device worn at night.”
“The choice is completely yours. We often recommend both: it gives longer-lasting protection, and it also prevents the natural shifting of teeth that happens over time.”
“Yes. If one is lost or breaks you have another to wear right away, and a spare added during the same order comes at a reduced price, which lowers what you pay for each one. Better peace of mind and a better price per device.”
“No. A Keepers retainer is a passive appliance: it holds your teeth where they already are, it is not orthodontic treatment, and it does not straighten teeth.”
“A night guard is a custom clear appliance worn during sleep. It creates a protective layer between your upper and lower teeth, so the force from grinding and clenching lands on the guard instead of directly on your enamel and dental work.”
“No. A night guard protects teeth from the wear of grinding, but it does not stop the grinding itself or treat its cause. If you may need a diagnosis or treatment, consult a dentist or specialist.”
“Soft guards are easier to adapt to at first; hard guards are more durable and stable; dual-laminate guards combine a soft inside with a firmer outside. The evidence does not crown one best for everyone.”
