# Prevent iMG Care Guide

## How to clean, maintain, and protect your Prevent instrumented-mouthguard.

### **Daily Care**

**Rinse immediately.** As soon as you remove it, rinse with cool water to clear saliva and debris.

**Brush gently.** Use a soft-bristled toothbrush with a drop of mild, fragrance-free dish soap or a gentle, non-abrasive (non-whitening) toothpaste. Brush all surfaces, then rinse thoroughly with cool water.

**Air-dry completely.** Let the guard air-dry on a clean surface before returning it to its case. Never store it wet.

**Quick tip.** If sports drinks are regularly consumed, remove the mouthguard before drinking and swish water before reinserting to reduce staining.

### **Weekly Deep Clean**

Alongside daily cleaning, choose one soaking method once a week. Do not combine methods in the same session. After any soak, rinse thoroughly with cool water and air-dry before storing.

**Denture / retainer tablets (Efferdent, etc.).** Drop one tablet into a glass of cool water, submerge the guard, and follow the package instructions (typically 10–15 minutes). These mild oxidizing agents loosen plaque, whiten, and reduce bacteria.

**Hydrogen peroxide soak.** Mix equal parts 3% hydrogen peroxide and cool water. Soak for 10 minutes, then rinse well. Helps disinfect and lift surface stains.

**White vinegar soak.** Combine 1 part white vinegar with 3 parts cool water and soak for 15–30 minutes; the acidity breaks down mineral deposits from saliva. Rinse well to remove the smell before drying and storing.

 

### **What to Avoid**

**Hot water.** Never rinse under hot tap water or boil. Heat permanently warps the thermoplastic and destroys the fit.

**Dishwasher.** Exposes the guard to high heat and harsh detergent at once — both are destructive.

**Alcohol-based mouthwash.** Alcohol degrades the EVA plastic over time. For a mouthwash soak, choose an alcohol-free antibacterial rinse and confirm with your dentist first.

**Chlorine bleach.** Too harsh for mouthguard materials, and it leaves residue that is unsafe to put back in your mouth.

**Whitening or abrasive toothpastes.** These create micro-scratches in the softer EVA plastic, giving bacteria more surface to cling to.

**Leaving it loose in a bag or pocket.** A wet guard tossed in a gym bag or jersey pocket quickly accumulates bacteria, lint, and dirt.

**Hot car or direct sunlight.** Heat exposure, even from a parked car, can warp the material and permanently ruin the custom fit.
