Not All Mouthguards Are Created Equal
Every mouthguard on the market is one of three things: a stock guard (a one-size tray you bite down on), a boil-and-bite (thermoplastic you soften and mold yourself), or a custom-fit guard made from an impression of your actual teeth. Stock guards are not worth discussing — they protect poorly and fall out. The real decision is boil-and-bite versus custom-fit, and the differences are bigger than most athletes think.
Quick Verdict
BEST CHOICE FOR EVERY ATHLETE
Better fit, better comfort, and better retention - for athletes at every level.
Custom-FitLAST-RESORT OPTION
Generic-fit, added bulk, and less stability. Fine as a temporary backup, not as your everyday mouthguard.

How Boil-and-Bite Works
You mold it yourself.
01. Boil Water
Bring water to a rolling boil
02. Soften
Place guard in water for 30-60 seconds
03. Bite Down
Let cool a few seconds & bite down firmly
04. Cool
Place in cold water to set the shape.
05. Ready
You now have a rough negative of your bite.
The catch: The material thins where you bite hardest — exactly where impact protection matters most.
How Custom-Fit Works

Frequently Asked Questions
-
How long do you boil a boil-and-bite mouthguard?
Follow the package — typically 30–60 seconds in just-boiled water. Longer over-softens and thins the material.
-
How many times can you re-mold a boil-and-bite?
Once or twice at most — every reheat thins it and weakens protection.
-
Do custom mouthguards actually protect better?
The protection difference is consistency: engineered, uniform thickness over impact zones instead of material thinned wherever you bit hardest.
-
Why are dentist custom mouthguards so expensive?
You pay for office chair time plus an outside dental lab. Direct-to-consumer custom skips both, which is why it costs a fraction.
-
Is custom worth it for kids?
If they will wear it, yes — poor fit is the main reason kids abandon mouthguards mid-season.
-
What if I mess up my at-home impression?
Kits include two attempts, and replacement putty is free if you need another try.
-
Can I use HSA/FSA funds for a custom mouthguard?
Yes — TRUFIT custom guards are HSA/FSA eligible.
-
How long does a custom mouthguard last?
Multiple seasons with basic care — rinse after use, weekly cleaning, ventilated case. Your saved scan makes replacement one click.
