FAQ
Do custom sports mouth guards prevent concussions?
A straight answer first, then the context behind it, from the technicians who do the work.
THE SHORT ANSWER
Current evidence does not support the claim that any mouth guard, custom or stock, reliably prevents concussions. Custom-fitted guards do reduce the risk of dental trauma, lacerations, and jaw fractures. Some studies suggest custom guards may attenuate certain impact forces transmitted through the mandible, but no peer-reviewed consensus establishes them as a concussion-prevention device.
THE CONTEXT
What sits behind it
The concussion-prevention claim circulates widely in sports marketing, but regulatory language matters here. The FDA classifies mouth guards as Class I devices for dental protection, not head injury prevention. A 2021 systematic review in the British Journal of Sports Medicine found insufficient evidence to recommend any mouth guard design specifically for concussion reduction. Dentists prescribing or recommending custom guards should frame them accurately to patients and athletes as dental protective devices, not neurological ones.
What custom guards do deliver is well-documented: a precise fit over the dentition reduces displacement forces on teeth, soft tissue lacerations drop significantly compared to stock alternatives, and occlusal stability during impact is measurably better. For a general dentist or team-affiliated practice writing mouth guard prescriptions, that clinical framing keeps recommendations defensible and avoids liability tied to overclaimed outcomes.
For practices sending mouth guard cases to a dental lab, the fabrication workflow has moved substantially digital. An intraoral scan replaces the alginate impression, the STL file goes direct to milling or thermoforming, and turnaround compresses from weeks to days. Dani Dental fabricates custom sports appliances from digital files, with every case reviewed by the technician on the order before it ships.
