30-Day Fit Guarantee
We’re confident your retainers will fit perfectly. If they don’t, you can return them within 30 days for a replacement.
Custom retainers keep teeth straight after braces or aligners by holding alignment and preventing shifting/spacing, while a custom night guard protects against grinding/clenching to reduce enamel wear and morning jaw tension. If your goal is alignment retention, choose retainers; if you wake with jaw soreness or headaches, choose a night guard; need both? use retainer + night guard per your dentist’s advice. Expect a snug, clear retainer (a mild 1–3 night lisp is normal) and pick night-guard thickness (1.5–3.0 mm or dual-laminate) based on grinding severity.

How do I know if my night guard is working?
You should notice less morning jaw tension within 3–7 nights and fewer grinding headaches within 1–2 weeks.
Partners often report quieter sleep (less grinding noise). Teeth should feel less sensitive on waking, and your guard will show even wear marks rather than chips or through-holes.
At your next dental checkup, your dentist should see reduced enamel wear and fewer fractures or craze lines. If jaw fatigue persists after 2–3 weeks, consider a thicker or dual-laminate guard, and ensure the fit is snug without rocking.
Can retainers fix minor relapse, or do they only maintain alignment?
Retainers maintain alignment; they are not designed to actively move teeth. For visible gaps or overlaps, short clear-aligner treatment may be required. Order a fresh retainer set to stabilize your current position and book an assessment. Nightly retainer wear afterward helps prevent future relapse.
What thickness or type of night guard should I choose for my grinding level?
Light grinding: ~1.3 mm (easy to adapt). Moderate: 2 mm (balance of comfort and durability). Heavy grinding, crack history, or veneers: 2 mm or dual-laminate (hard exterior, soft interior).
Most people prefer upper guards for stability, but choose the arch that is most comfortable and compatible with your dental work. If you chew through guards or wake with fatigue, step up a thickness.
Will retainers or night guards affect speech or sleep? How long to adjust?
A mild lisp is common for 1–3 nights; reading aloud for 5–10 minutes speeds adaptation. Most users sleep normally within about a week. If you are sensitive, choose the thinnest guard that still protects.
Persistent speech issues usually indicate the device is too loose or tight and needs adjustment. If that's the case, request a refit within 30 days under the Perfect Fit Guarantee.
How do I keep retainers and night guards clear, odour-free, and long-lasting?
Daily: rinse with cool water and brush gently with a soft brush (no toothpaste). 2–3x per week: use non-abrasive cleaning tablets like our Petal Pods; avoid hot water and alcohol-based cleaners. For clinical grade cleaning, use our Petal Ultrasonic Cleaner
Dry fully and store in a ventilated case. Avoid heat, dishwashers, boiling, and harsh chemicals. Replace retainers and night guards about every 5-6 months.
