Buying Guide: Key Considerations For Choosing A Night Guard
- Custom fit vs. ready-to-wear: Do you prefer a fully moldable guard at home, or a pre-formed option you can wear immediately?
- Material and safety: Look for BPA-free materials and soft cushioning on the top layer to reduce gum and cheek irritation.
- Durability and reuse: Reusable guards offer longer-term cost savings, while disposables suit travel or short-term needs.
- Teeth coverage: Some guards protect only the front teeth, while others cover both front and back teeth for broader protection.
- Cleaning and hygiene: Check if the kit includes a cleaning accessory or case to maintain hygiene between uses.
- Fit variability: For sleepers with different jaw positions, options with adjustable or multi-size packs can improve comfort.
- Ease of use: A shorter molding time and straightforward steps reduce the risk of an improper fit.
