Why Pro Teeth Guard can still justify the premium
The company says its hard guard can last approximately 2–5 years depending on grinding severity. That is a manufacturer estimate, not a guarantee, but it gives us a useful ownership-cost variable. A $220 guard that lasts several years can beat a $115 guard replaced frequently.
Why SportingSmiles is the value benchmark
The Flexible Super Hard guard is currently $120, includes the impression kit and U.S. shipping, and SportingSmiles publishes a 90-day warranty. Its direct product page explicitly positions it for severe grinding and clenching.
When an online guard is the wrong problem to solve
Cracked teeth, major tooth wear, persistent jaw pain, locking/clicking, headaches, or a suspected sleep disorder justify professional evaluation. A guard may protect teeth, but it does not establish why someone is grinding.
