Orthodontist in Toronto, North York, Scarborough recommends mouthguards

The physical contact with playing sports in Toronto, North York, Scarborough, East York and the GTA can result in damage to braces and teeth.  Mouth guards not only protect your teeth, but they create a separation between your skull and the condyle which is the upper head of your lower jaw, decreasing the risk of concussions.  Drs. Noble, Cassolato and team stress the importance of wearing mouth guards and protective gear when playing contact sports.  Please contact your general dentist or orthodontist to fabricate a custom made mouth guard or for a stock mouth guard if you're wearing braces.
